Which is the most important hardware to mine cryptocurrency?

Crypto mining equipment is specifically designed to solve blockchain hash functions at a faster rate than other hardware solutions. Traditional computers are built with a processor known as a Central Processing Unit (CPU), which is designed to compute the functions needed for a standard computer.
Alternatively, mining hardware is built with different, more advance processors. Yet, these aren’t just high-powered computers. Crypto mining equipment is more efficient than typical hardware at solving computational hashes required to successfully mine blockchains.
There are several things to look out for when it comes to purchasing cryptocurrency mining hardware and equipment.[1]
First, these machines must not just be powerful, but energy efficient as well. Since the number one cost in crypto mining is electricity, a good piece of mining equipment must consume less power while still maintaining its high-powered usage. This makes a key factor in crypto mining hardware hashes per second per watt of power, which determines how much power is consumed for a given amount of hash power.
Second, because cryptocurrency mining is done 24/7/365, the equipment used to mine must be able to operate on a continuous basis. This means, equipment is designed for optimal cooling so as to not overheat from continuous use, as well as setting up equipment in a way which will allow for the most optimal cooling. If you are unsure how this can be done it may be best to outsource the installation and hosting of your mining hardware to a third-party provider with the proper tools and resources to service mining equipment.
There are three types of mining hardware: GPU, FPGA, and ASIC. The type of hardware used is dependent on the blockchain being mined. While ASIC-based hardware may be the most powerful for some blockchains (such as Bitcoin), they are rendered almost useless in other blockchains (such as ZCash) whose hashing algorithm is designed to be resistant to ASIC hardware.
Choosing the correct piece of mining hardware is one of the most important parts of cryptocurrency mining, as the wrong choice could result in a significant loss of potential profits and time.
All in all, it has become clear over the past several years that cryptocurrency mining hardware is necessary for anyone looking to make a profit in mining. Determining which piece of mining equipment is most suitable for your needs is dependent on many factors such as your budget and the blockchain being mined.

Transcript of discussion between an ASIC designer and several proof-of-work designers from #monero-pow channel on Freenode this morning

[08:07:01] lukminer contains precompiled cn/r math sequences for some blocks:
[08:07:11] try that with RandomX :P
[08:09:00] tevador: are you ready for some RandomX feedback? it looks like the CNv4 is slowly stabilizing, hashrate comes down...
[08:09:07] how does it even make sense to precompile it?
[08:09:14] mine 1% faster for 2 minutes?
[08:09:35] naturally we think the entire asic-resistance strategy is doomed to fail :) but that's a high-level thing, who knows. people may think it's great.
[08:09:49] about RandomX: looks like the cache size was chosen to make it GPU-hard
[08:09:56] looking forward to more docs
[08:11:38] after initial skimming, I would think it's possible to make a 10x asic for RandomX. But at least for us, we will only make an ASIC if there is not a total ASIC hostility there in the first place. That's better for the secret miners then.
[08:13:12] What I propose is this: we are working on an Ethash ASIC right now, and once we have that working, we would invite tevador or whoever wants to come to HK/Shenzhen and we walk you guys through how we would make a RandomX ASIC. You can then process this input in any way you like. Something like that.
[08:13:49] unless asics (or other accelerators) re-emerge on XMR faster than expected, it looks like there is a little bit of time before RandomX rollout
[08:14:22] 10x in what measure? $/hash or watt/hash?
[08:14:46] watt/hash
[08:15:19] so you can make 10 times more efficient double precisio FPU?
[08:16:02] like I said let's try to be productive. You are having me here, let's work together!
[08:16:15] continue with RandomX, publish more docs. that's always helpful.
[08:16:37] I'm trying to understand how it's possible at all. Why AMD/Intel are so inefficient at running FP calculations?
[08:18:05] midipoet ([email protected]/web/ has joined #monero-pow
[08:18:17] hardware development works the other way round. We start with 1) math then 2) optimization priority 3) hw/sw boundary 4) IP selection 5) physical implementation
[08:22:32] This still doesn't explain at which point you get 10x
[08:23:07] Weren't you the ones claiming "We can accelerate ProgPoW by a factor of 3x to 8x." ? I find it hard to believe too.
[08:30:20] sure
[08:30:26] so my idea: first we finish our current chip
[08:30:35] from simulation to silicon :)
[08:30:40] we love this stuff... we do it anyway
[08:30:59] now we have a communication channel, and we don't call each other names immediately anymore: big progress!
[08:31:06] you know, we russians have a saying "it was smooth on paper, but they forgot about ravines"
[08:31:12] So I need a bit more details
[08:31:16] ha ha. good!
[08:31:31] that's why I want to avoid to just make claims
[08:31:34] let's work
[08:31:40] RandomX comes in Sep/Oct, right?
[08:31:45] Maybe
[08:32:20] We need to audit it first
[08:32:31] ok
[08:32:59] we don't make chips to prove sw devs that their assumptions about hardware are wrong. especially not if these guys then promptly hardfork and move to the next wrong assumption :)
[08:33:10] from the outside, this only means that hw & sw are devaluing each other
[08:33:24] neither of us should do this
[08:33:47] we are making chips that can hopefully accelerate more crypto ops in the future
[08:33:52] signing, verifying, proving, etc.
[08:34:02] PoW is just a feature like others
[08:34:18] sech1: is it easy for you to come to Hong Kong? (visa-wise)
[08:34:20] or difficult?
[08:34:33] or are you there sometimes?
[08:34:41] It's kind of far away
[08:35:13] we are looking forward to more RandomX docs. that's the first step.
[08:35:31] I want to avoid that we have some meme "Linzhi says they can accelerate XYZ by factor x" .... "ha ha ha"
[08:35:37] right? we don't want that :)
[08:35:39] doc is almost finished
[08:35:40] What docs do you need? It's described pretty good
[08:35:41] so I better say nothing now
[08:35:50] we focus on our Ethash chip
[08:36:05] then based on that, we are happy to walk interested people through the design and what else it can do
[08:36:22] that's a better approach from my view than making claims that are laughed away (rightfully so, because no silicon...)
[08:36:37] ethash ASIC is basically a glorified memory controller
[08:36:39] sech1: tevador said something more is coming (he just did it again)
[08:37:03] yes, some parts of RandomX are not described well
[08:37:10] like dataset access logic
[08:37:37] RandomX looks like progpow for CPU
[08:37:54] yes
[08:38:03] it is designed to reflect CPU
[08:38:34] so any ASIC for it = CPU in essence
[08:39:04] of course there are still some things in regular CPU that can be thrown away for RandomX
[08:40:20] uncore parts are not used, but those will use very little power
[08:40:37] except for memory controller
[08:41:09] I'm just surprised sometimes, ok? let me ask: have you designed or taped out an asic before? isn't it risky to make assumptions about things that are largely unknown?
[08:41:23] I would worry
[08:41:31] that I get something wrong...
[08:41:44] but I also worry like crazy that CNv4 will blow up, where you guys seem to be relaxed
[08:42:06] I didn't want to bring up anything RandomX because CNv4 is such a nailbiter... :)
[08:42:15] how do you guys know you don't have asics in a week or two?
[08:42:38] we don't have experience with ASIC design, but RandomX is simply designed to exactly fit CPU capabilities, which is the best you can do anyways
[08:43:09] similar as ProgPoW did with GPUs
[08:43:14] some people say they want to do asic-resistance only until the vast majority of coins has been issued
[08:43:21] that's at least reasonable
[08:43:43] yeah but progpow totally will not work as advertised :)
[08:44:08] yeah, I've seen that comment about progpow a few times already
[08:44:11] which is no surprise if you know it's just a random sales story to sell a few more GPUs
[08:44:13] RandomX is not permanent, we are expecting to switch to ASIC friendly in a few years if possible
[08:44:18] yes
[08:44:21] that makes sense
[08:44:40] linzhi-sonia: how so? will it break or will it be asic-able with decent performance gains?
[08:44:41] are you happy with CNv4 so far?
[08:45:10] ah, long story. progpow is a masterpiece of deception, let's not get into it here.
[08:45:21] if you know chip marketing it makes more sense
[08:45:24] linzhi-sonia: So far? lol! a bit early to tell, don't you think?
[08:45:35] the diff is coming down
[08:45:41] first few hours looked scary
[08:45:43] I remain skeptical: I only see ASICs being reasonable if they are already as ubiquitous as smartphones
[08:45:46] yes, so far so good
[08:46:01] we kbew the diff would not come down ubtil affter block 75
[08:46:10] yes
[08:46:22] but first few hours it looks like only 5% hashrate left
[08:46:27] looked
[08:46:29] now it's better
[08:46:51] the next worry is: when will "unexplainable" hashrate come back?
[08:47:00] you hope 2-3 months? more?
[08:47:05] so give it another couple of days. will probably overshoot to the downside, and then rise a bit as miners get updated and return
[08:47:22] 3 months minimum turnaround, yes
[08:47:28] nah
[08:47:36] don't underestimate asicmakers :)
[08:47:54] you guys don't get #1 priority on chip fabs
[08:47:56] 3 months = 90 days. do you know what is happening in those 90 days exactly? I'm pretty sure you don't. same thing as before.
[08:48:13] we don't do any secret chips btw
[08:48:21] 3 months assumes they had a complete design ready to go, and added the last minute change in 1 day
[08:48:24] do you know who is behind the hashrate that is now bricked?
[08:48:27] innosilicon?
[08:48:34] hyc: no no, and no. :)
[08:48:44] hyc: have you designed or taped out a chip before?
[08:48:51] yes, many years ago
[08:49:10] then you should know that 90 days is not a fixed number
[08:49:35] sure, but like I said, other makers have greater demand
[08:49:35] especially not if you can prepare, if you just have to modify something, or you have more programmability in the chip than some people assume
[08:50:07] we are chipmakers, we would never dare to do what you guys are doing with CNv4 :) but maybe that just means you are cooler!
[08:50:07] and yes, programmability makes some aspect of turnaround easier
[08:50:10] all fine
[08:50:10] I hope it works!
[08:50:28] do you know who is behind the hashrate that is now bricked?
[08:50:29] inno?
[08:50:41] we suspect so, but have no evidence
[08:50:44] maybe we can try to find them, but we cannot spend too much time on this
[08:50:53] it's probably not so much of a secret
[08:51:01] why should it be, right?
[08:51:10] devs want this cat-and-mouse game? devs get it...
[08:51:35] there was one leak saying it's innosilicon
[08:51:36] so you think 3 months, ok
[08:51:43] inno is cool
[08:51:46] good team
[08:51:49] IP design house
[08:51:54] in Wuhan
[08:52:06] they send their people to conferences with fake biz cards :)
[08:52:19] pretending to be other companies?
[08:52:26] sure
[08:52:28] ha ha
[08:52:39] so when we see them, we look at whatever card they carry and laugh :)
[08:52:52] they are perfectly suited for secret mining games
[08:52:59] they made at most $6 million in 2 months of mining, so I wonder if it was worth it
[08:53:10] yeah. no way to know
[08:53:15] but it's good that you calculate!
[08:53:24] this is all about cost/benefit
[08:53:25] then you also understand - imagine the value of XMR goes up 5x, 10x
[08:53:34] that whole "asic resistance" thing will come down like a house of cards
[08:53:41] I would imagine they sell immediately
[08:53:53] the investor may fully understand the risk
[08:53:57] the buyer
[08:54:13] it's not healthy, but that's another discussion
[08:54:23] so mid-June
[08:54:27] let's see
[08:54:49] I would be susprised if CNv4 ASICs show up at all
[08:54:56] surprised*
[08:54:56] why?
[08:55:05] is only an economic question
[08:55:12] yeah should be interesting. FPGAs will be near their limits as well
[08:55:16] unless XMR goes up a lot
[08:55:19] no, not *only*. it's also a technology question
[08:55:44] you believe CNv4 is "asic resistant"? which feature?
[08:55:53] it's not
[08:55:59] cnv4 = Rabdomx ?
[08:56:03] no
[08:56:07] cnv4=cryptinight/r
[08:56:11] ah
[08:56:18] CNv4 is the one we have now, I think
[08:56:21] since yesterday
[08:56:30] it's plenty enough resistant for current XMR price
[08:56:45] that may be, yes!
[08:56:55] I look at daily payouts. XMR = ca. 100k USD / day
[08:57:03] it can hold until October, but it's not asic resistant
[08:57:23] well, last 24h only 22,442 USD :)
[08:57:32] I think 80 h/s per watt ASICs are possible for CNv4
[08:57:38] linzhi-sonia where do you produce your chips? TSMC?
[08:57:44] I'm cruious how you would expect to build a randomX ASIC that outperforms ARM cores for efficiency, or Intel cores for raw speed
[08:57:48] curious
[08:58:01] yes, tsmc
[08:58:21] Our team did the world's first bitcoin asic, Avalon
[08:58:25] and upcoming 2nd gen Ryzens (64-core EPYC) will be a blast at RandomX
[08:58:28] designed and manufactured
[08:58:53] still being marketed?
[08:59:03] linzhi-sonia: do you understand what xmr wants to achieve, community-wise?
[08:59:14] Avalon? as part of Canaan Creative, yes I think so.
[08:59:25] there's not much interesting oing on in SHA256
[08:59:29] Inge-: I would think so, but please speak
[08:59:32] hyc: yes
[09:00:28] linzhi-sonia: i am curious to hear your thoughts. I am fairly new to this space myself...
[09:00:51] oh
[09:00:56] we are grandpas, and grandmas
[09:01:36] yet I have no problem understanding why ASICS are currently reviled.
[09:01:48] xmr's main differentiators to, let's say btc, are anonymity and fungibility
[09:01:58] I find the client terribly slow btw
[09:02:21] and I think the asic-forking since last may is wrong, doesn't create value and doesn't help with the project objectives
[09:02:25] which "the client" ?
[09:02:52] Monero GUI client maybe
[09:03:12] MacOS, yes
[09:03:28] What exactly is slow?
[09:03:30] linzhi-sonia: I run my own node, and use the CLI and Monerujo. Have not had issues.
[09:03:49] staying in sync
[09:03:49] linzhi-sonia: decentralization is also a key principle
[09:03:56] one that Bitcoin has failed to maintain
[09:04:39] hmm
[09:05:00] looks fairly decentralized to me. decentralization is the result of 3 goals imo: resilient, trustless, permissionless
[09:05:28] don't ask a hardware maker about physical decentralization. that's too ideological. we focus on logical decentralization.
[09:06:11] physical decentralization is important. with bulk of bitnoin mining centered on Chinese hydroelectric dams
[09:06:19] have you thought about including block data in the PoW?
[09:06:41] yes, of course.
[09:07:39] is that already in an algo?
[09:08:10] hyc: about "centered on chinese hydro" - what is your source? the best paper I know is this:
[09:09:01] linzhi-sonia: do you mine on your ASICs before you sell them?
[09:09:13] besides testing of course
[09:09:45] that paper puts Chinese btc miners at 60% max
[09:10:05] tevador: I think everybody learned that that is not healthy long-term!
[09:10:16] because it gives the chipmaker a cost advantage over its own customers
[09:10:33] and cost advantage leads to centralization (physical and logical)
[09:10:51] you guys should know who finances progpow and why :)
[09:11:05] but let's not get into this, ha ha. want to keep the channel civilized. right OhGodAGirl ? :)
[09:11:34] tevador: so the answer is no! 100% and definitely no
[09:11:54] that "self-mining" disease was one of the problems we have now with asics, and their bad reputation (rightfully so)
[09:13:08] I plan to write a nice short 2-page paper or so on our chip design process. maybe it's interesting to some people here.
[09:13:15] basically the 5 steps I mentioned before, from math to physical
[09:13:32] linzhi-sonia: the paper you linked puts 48% of bitcoin mining in Sichuan. the total in China is much more than 60%
[09:13:38] need to run it by a few people to fix bugs, will post it here when published
[09:14:06] hyc: ok! I am just sharing the "best" document I know today. it definitely may be wrong and there may be a better one now.
[09:14:18] hyc: if you see some reports, please share
[09:14:51] hey I am really curious about this: where is a PoW algo that puts block data into the PoW?
[09:15:02] the previous paper I read is from here
[09:15:38] hyc: you said that already exists? (block data in PoW)
[09:15:45] it would make verification harder
[09:15:49] linzhi-sonia:
[09:15:51] but for chips it would be interesting
[09:15:52] we discussed the possibility about a year ago
[09:16:05] oh good links! thanks! need to read...
[09:16:06] I think that paper by dryja was original
[09:17:53] since we have a nice flow - second question I'm very curious about: has anyone thought about in-protocol rewards for other functions?
[09:18:55] we've discussed micropayments for wallets to use remote nodes
[09:18:55] you know there is a lot of work in other coins about STARK provers, zero-knowledge, etc. many of those things very compute intense, or need to be outsourced to a service (zether). For chipmakers, in-protocol rewards create an economic incentive to accelerate those things.
[09:19:50] whenever there is an in-protocol reward, you may get the power of ASICs doing something you actually want to happen
[09:19:52] it would be nice if there was some economic reward for running a fullnode, but no one has come up with much more than that afaik
[09:19:54] instead of fighting them off
[09:20:29] you need to use asics, not fight them. that's an obvious thing to say for an asicmaker...
[09:20:41] in-protocol rewards can be very powerful
[09:20:50] like I said before - unless the ASICs are so useful they're embedded in every smartphone, I dont see them being a positive for decentralization
[09:21:17] if they're a separate product, the average consumer is not going to buy them
[09:21:20] now I was talking about speedup of verifying, signing, proving, etc.
[09:21:23] they won't even know what they are
[09:22:07] if anybody wants to talk about or design in-protocol rewards, please come talk to us
[09:22:08] the average consumer also doesn't use general purpose hardware to secure blockchains either
[09:22:14] not just for PoW, in fact *NOT* for PoW
[09:22:32] it requires sw/hw co-design
[09:23:10] we are in long-term discussions/collaboration over this with Ethereum, Bitcoin Cash. just talk right now.
[09:23:16] this was recently published though suggesting more uptake though I guess
[09:23:29] I find it pretty hard to believe their numbers
[09:24:03] well
[09:24:09] sorry, original article:
[09:24:11] just talk, no? rumors
[09:24:18] college students are already more educated than the average consumer
[09:24:29] we are not seeing many such customers anymore
[09:24:30] it's data from cisco monitoring network traffic
[09:24:33] and they're always looking for free money
[09:24:48] of course anyone with "free" electricity is inclined to do it
[09:24:57] but look at the rates, cannot make much money
[09:26:06] Ethereum is a bloated collection of bugs wrapped in a UI. I suppose they need all the help they can get
[09:26:29] Bitcoin Cash ... just another get rich quick scheme
[09:26:38] hmm :)
[09:26:51] I'll give it back to you, ok? ha ha. arrogance comes before the fall...
[09:27:17] maye we should have a little fun with CNv4 mining :)
[09:27:25] ;)
[09:27:38] come on. anyone who has watched their track record... $75M lost in ETH at DAO hack
[09:27:50] every smart contract that comes along is just waiting for another hack
[09:27:58] I just wanted to throw out the "in-protocol reward" thing, maybe someone sees the idea and wants to cowork. maybe not. maybe it's a stupid idea.
[09:29:18] linzhi-sonia: any thoughts on CN-GPU?
[09:29:55] CN-GPU has one positive aspect - it wastes chip area to implement all 18 hash algorithms
[09:30:19] you will always hear roughly the same feedback from me:
[09:30:52] "This algorithm very different, it heavy use floating point operations to hurt FPGAs and general purpose CPUs"
[09:30:56] the problem is, if it's profitable for people to buy ASIC miners and mine, it's always more profitable for the manufacturer to not sell and mine themselves
[09:31:02] "hurt"
[09:31:07] what is the point of this?
[09:31:15] it totally doesn't work
[09:31:24] you are hurting noone, just demonstrating lack of ability to think
[09:31:41] what is better: algo designed for chip, or chip designed for algo?
[09:31:43] fireice does it on daily basis, CN-GPU is a joke
[09:31:53] tevador: that's not really true, especially in a market with such large price fluctuations as cryptocurrency
[09:32:12] it's far less risky to sell miners than mine with them and pray that price doesn't crash for next six months
[09:32:14] I think it's great that crypto has a nice group of asicmakers now, hw & sw will cowork well
[09:32:36] jwinterm yes, that's why they premine them and sell after
[09:32:41] PoW is about being thermodynamically and cryptographically provable
[09:32:45] premining with them is taking on that risk
[09:32:49] not "fork when we think there are asics"
[09:32:51] business is about risk minimization
[09:32:54] that's just fear-driven
[09:33:05] Inge-: that's roughly the feedback
[09:33:24] I'm not saying it hasn't happened, but I think it's not so simple as saying "it always happens"
[09:34:00] jwinterm: it has certainly happened on BTC. and also on XMR.
[09:34:19] ironically, please think about it: these kinds of algos indeed prove the limits of the chips they were designed for. but they don't prove that you cannot implement the same algo differently! cannot!
[09:34:26] Risk minimization is not starting a business at all.
[09:34:34] proof-of-gpu-limit. proof-of-cpu-limit.
[09:34:37] imagine you have a money printing machine, would you sell it?
[09:34:39] proves nothing for an ASIC :)
[09:35:05] linzhi-sonia: thanks. I dont think anyone believes you can't make a more efficient cn-gpu asic than a gpu - but that it would not be orders of magnitude faster...
[09:35:24] ok
[09:35:44] like I say. these algos are, that's really ironic, designed to prove the limitatios of a particular chip in mind of the designer
[09:35:50] exactly the wrong way round :)
[09:36:16] like the cache size in RandomX :)
[09:36:18] beautiful
[09:36:29] someone looked at GPU designs
[09:37:31] linzhi-sonia can you elaborate? Cache size in RandomX was selected to fit CPU cache
[09:37:52] yes
[09:38:03] too large for GPU
[09:38:11] as I said, we are designing the algorithm to exactly fit CPU capabilities, I do not claim an ASIC cannot be more efficient
[09:38:16] ok!
[09:38:29] when will you do the audit?
[09:38:35] will the results be published in a document or so?
[09:38:37] I claim that single-chip ASIC is not viable, though
[09:39:06] you guys are brave, noone disputes that. 3 anti-asic hardforks now!
[09:39:18] 4th one coming
[09:39:31] 3 forks were done not only for this
[09:39:38] they had scheduled updates in the first place
[09:48:10] Monero is the #1 anti-asic fighter
[09:48:25] Monero is #1 for a lot of reasons ;)
[09:48:40] It's the coin with the most hycs.
[09:48:55] mooooo
[09:59:06] sneaky integer overflow, bug squished
[10:38:00] p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has joined #monero-pow
[11:10:53] The convo here is wild
[11:12:29] it's like geo-politics at the intersection of software and hardware manufacturing for thermoeconomic value.
[11:13:05] ..and on a Sunday.
[11:15:43] midipoet: hw and sw should work together and stop silly games to devalue each other. to outsiders this is totally not attractive.
[11:16:07] I appreciate the positive energy here to try to listen, learn, understand.
[11:16:10] that's a start
[11:16:48] <-- p0nziph0ne ([email protected]/vpn/privateinternetaccess/p0nziph0ne) has quit (Quit: Leaving)
[11:16:54] we won't do silly mining against xmr "community" wishes, but not because we couldn'd do it, but because it's the wrong direction in the long run, for both sides
[11:18:57] linzhi-sonia: I agree to some extent. Though, in reality, there will always be divergence between social worlds. Not every body has the same vision of the future. Reaching societal consensus on reality tomorrow is not always easy
[11:20:25] absolutely. especially at a time when there is so much profit to be made from divisiveness.
[11:20:37] someone will want to make that profit, for sure
[11:24:32] Yes. Money distorts.
[11:24:47] Or of the two
[11:26:35] Too much physical money will distort rays of light passing close to it indeed.

GPU Mining Crash Course - START HERE!

Welcome All to the GPUMining Crash Course!
With the increase in prices in cryptocurrency, a lot of people are getting back into mining and a lot of people are brand new to the concept overall. So, I quickly wrote this crash course to help you understand what to expect and how to successfully mine your first cryptocurrency. This crash course isn't gonna have all of the fluff you'd see in a normal publication. This is just everything you need to know to get up and running on your first cryptocurrency mining rig.

What is cryptocurrency mining?

One of the main things about cryptocurrencies is that they are "decentralized". Sounds great, but WTF does that even mean? Well, the easiest way to explain it is...
You know how if you want to send your friend/family money digitally, you can do so through your bank. Your bank likely takes a transaction fee and in a few days they will transfer the money. Since cryptocurrencies are decentralized, they don't have a bank or organization to fulfill the transfer of money. Instead, they outsource the computing power of their cryptocurrency network to miners (soon to be you). These miners are verifying transactions, securing the blockchain, and powering the cryptocurrency's specific network among other things. As an incentive, the miners collect transaction fees on the transactions that they verify and collect block rewards while new currency is still being introduced into the ecosystem.

What kind of rig should I build?

You can mine cryptocurrencies using your CPU, GPU, FPGA, or ASIC, but this is a GPU Mining subreddit, so I will cater this to GPUs.
For building a great all-around GPU rig, there are two models of GPUs that I'd recommend:
Both of these GPUs have solid hashrates across most mining algorithms and for a decent price! You should be able to find both of these kinds of GPUs used for around $200-$250 each, which is a great price if you know what happened during the last mining craze! ($200 GPUs were out of stock everywhere and people were reselling them for $600+ each)
There are also plenty of great AMD GPUs for mining, but I've worked mostly with Nvidia so that's why both of my recommendations are Nvidia and not AMD.
Other parts to your rig that you'll need are listed below. Most of these can be pieces of crap and are just needed to make the rig actually run, but the one spot you DON'T want to cheap out on is the power supply unit. A decent power supply unit will keep your home from burning down while also keeping your rigs up and running smoothly. Here are my recommendations:

She's built, now what?

Now you need to do a few things. I am a Windows miner, so I will be speaking to Windows here:
  1. Update Windows - Do all of the updates. Just do it.
  2. Update Drivers - Go to the EVGA website and download GeForce experience. It will keep your GPU drivers up to date.
  3. Go to Windows Device Manager and make sure all of your GPUs show up under "Display Adapters". If it is there, but it isn't showing the Name/Model of the GPU as the name, right click it and select "Update Driver". This should fix it.
Assuming you've done all of this, you're ready to download a mining application.

Mining Software

There are tons to choose from! Claymore, Phoenix, EWBF, LolMiner, etc... It can be overwhelming pretty quickly since they all have different algorithm support, speeds, efficiencies, and a whole lot more. On top of that, in order to get them running you need to set up batch files to call the proper exe, point you to the correct pool, and a whole bunch of other stuff that can be confusing to a new user. Not to mention, you will probably need a separate miner, config file, batch file, etc. for each different algorithm that you're interested in mining on.
Instead, I recommend that you download a miner management software that will take care of most of this tedious work for you. There are a few in the sidebar, but the /GPUMining favorite is AIOMiner. It was developed by our very own community member, xixspiderxix with the intention of making mining as easy as possible to do and without any fees. It supports over 100 different algorithms, so you'll be able to mine nearly ANY cryptocurrency you'd like. Just download it from their website and it will take you through a quick tutorial to help you get set up! You can also connect your rig to their website for remote monitoring and control. You've probably seen a few of their posts around this subreddit.
Other Windows mining softwares include:
Note: Many mining softwares have fees built into them. Most are around 1%, but can go as high as 5% or greater! You want a mining software with little or no fees at all so that you get to keep as much cryptocurrency as possible. These fees aren't something you actively pay, the software will automatically take it by mining on the developers behalf for a given amount of time and then switching back to mining on your own behalf. So, please be diligent in the software that you evaluate and make sure it is reputable.

I keep hearing about NiceHash. What is that?

The asshole of the mining industry. Jk, but not really.
NiceHash is a software program that allows you to sell your rig's hashing power to someone on their marketplace. They market themselves as profitable mining, but you're not really mining. You're selling your power in exchange for Bitcoin.
They did a great job telling people that with them, you're always mining the most profitable coin, but that's just not true. Since it is a mining marketplace, they make you mine whatever their most expensive contract is. If their contracts are below market prices, then you're not operating as efficiently and profitably as you could be.
NiceHash also has a sketchy history, which continues to this day. In 2017, they were hacked and lost $65M worth of Bitcoin. No one got paid out for MONTHS and many of their executives conveniently resigned. Their platform is also used to destroy cryptocurrencies. Since people are able to purchase mining power on their platform, people have used their platform to purchase enough mining power to control individual cryptocurrencies and duplicate coins, which increased the malicious user's wealth while completely destroying the integrity of the coin's blockchain. HoriZEN (formerly ZenCash), Ethereum Classic, and many other great cryptocurrencies have been the victim of NiceHash's platform.
For this and many other reasons, we highly recommend that you stay AWAY from Nicehash. We understand that it is extremely easy to use and you get paid in bitcoin, but they are destroying the industry with their greed and lack of motivation to change their platform for the protection of cryptocurrencies.

Concluding Thoughts

This is pretty much everything you need to know to get started. We covered the hardware, setting up the software, which software to use, and AIOMiner's tutorial will get you up to speed on how to actually mine the cryptocurrency that you want better than I can explain it, so I'll leave that part to them.
If you have any questions on this crash course, please leave a comment below where myself and other community members will be able to help you out.

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners
Thank you for inviting Horizen to the GPU mining AMA!
ZEN had a great run of GPU mining that lasted well over a year, and brought lots of value to the early Zclassic miners. It is mined using Equihash protocol, and there have been ASIC miners available for the algorithm since about June of 2018. GPU mining is not really profitable for Horizen at this point in time.
We’ve got a lot of miners in the Horizen community, and many GPU miners also buy ASIC miners. Happy to talk about algorithm changes, security, and any other aspect of mining in the questions below. There are also links to the Horizen website, blog post, etc. below.
So, if I’m not here to ask you to mine, hold, and love ZEN, what can I offer? Notes on some of the lessons I’ve learned about maximizing mining profitability. An update on Horizen - there is life after moving on from GPU mining. As well as answering your questions during the next 7 days.

Mining for Profitability - Horizen (formerly ZenCash) Thanks Early GPU Miners

Author: Rolf Versluis - co-founder of Horizen

In GPU mining, just like in many of the activities involved with Bitcoin and cryptocurrencies, there is both a cycle and a progression. The Bitcoin price cycle is fairly steady, and by creating a personal handbook of actions to take during the cycle, GPU miners can maximize their profitability.
Maximizing profitability isn't the only aspect of GPU mining that is important, of course, but it is helpful to be able to invest in new hardware, and be able to have enough time to spend on building and maintaining the GPU miners. If it was a constant process that also involved losing money, then it wouldn't be as much fun.

Technology Progression

For a given mining algorithm, there is definitely a technology progression. We can look back on the technology that was used to mine Bitcoin and see how it first started off as Central Processing Unit (CPU) mining, then it moved to Graphical Processing Unit (GPU) mining, then Field Programmable Gate Array (FPGA), and then Application Specific Integrated Circuit (ASIC).
Throughout this evolution we have witnessed a variety of unsavory business practices that unfortunately still happen on occasion, like ASIC Miner manufacturers taking pre-orders 6 months in advance, GPU manufacturers creating commercial cards for large farms that are difficult for retail customers to secure and ASIC Miner manufacturers mining on gear for months before making it available for sale.
When a new crypto-currency is created, in many cases a new mining algorithm is created also. This is important, because if an existing algorithm was used, the coin would be open to a 51% attack from day one, and may not even be able to build a valid blockchain.
Because there's such a focus on profitable software, developers for GPU mining applications are usually able to write a mining application fairly rapidly, then iterate it to the limit of current GPU technology. If it looks like a promising new cryptocurrency, FPGA stream developers and ASIC Hardware Developers start working on their designs at the same time.
The people who create the hashing algorithms run by the miners are usually not very familiar with the design capabilities of Hardware manufacturers. Building application-specific semiconductors is an industry that's almost 60 years old now, and FPGA’s have been around for almost 35 years. This is an industry that has very experienced engineers using advanced design and modeling tools.
Promising cryptocurrencies are usually ones that are deploying new technology, or going after a big market, and who have at least a team of talented software developers. In the best case, the project has a full-stack business team involving development, project management, systems administration, marketing, sales, and leadership. This is the type of project that attracts early investment from the market, which will drive the price of the coin up significantly in the first year.
For any cryptocurrency that's a worthwhile investment of time, money, and electricity for the hashing, there will be a ASIC miners developed for it. Instead of fighting this technology progression, GPU miners may be better off recognizing it as inevitable, and taking advantage of the cryptocurrency cycle to maximize GPU mining profitability instead.

Cryptocurrency Price Cycle

For quality crypto projects, in addition to the one-way technology progression of CPU -> GPU -> FPGA -> ASIC, there is an upward price progression. More importantly, there is a cryptocurrency price cycle that oscillates around an overall upgrade price progression. Plotted against time, a cycle with an upward progressions looks like a sine wave with an ever increasing average value, which is what we see so far with the Bitcoin price.

Cryptocurrency price cycle and progression for miners
This means mining promising new cryptocurrencies with GPU miners, holding them as the price rises, and being ready to sell a significant portion in the first year. Just about every cryptocurrency is going to have a sharp price rise at some point, whether through institutional investor interest or by being the target of a pump-and-dump operation. It’s especially likely in the first year, while the supply is low and there is not much trading volume or liquidity on exchanges.
Miners need to operate in the world of government money, as well as cryptocurrency. The people who run mining businesses at some point have to start selling their mining proceeds to pay the bills, and to buy new equipment as the existing equipment becomes obsolete. Working to maximize profitability means more than just mining new cryptocurrencies, it also means learning when to sell and how to manage money.

Managing Cash for Miners

The worst thing that can happen to a business is to run out of cash. When that happens, the business usually shuts down and goes into bankruptcy. Sometimes an investor comes in and picks up the pieces, but at the point the former owners become employees.
There are two sides to managing cash - one is earning it, the other is spending it, and the cryptocurrency price cycle can tell the GPU miner when it is the best time to do certain things. A market top and bottom is easy to recognize in hindsight, and harder to see when in the middle of it. Even if a miner is able to recognize the tops and bottoms, it is difficult to act when there is so much hype and positivity at the top of the cycle, and so much gloom and doom at the bottom.
A decent rule of thumb for the last few cycles appears to be that at the top and bottom of the cycle BTC is 10x as expensive compared to USD as the last cycle. Newer crypto projects tend to have bigger price swings than Bitcoin, and during the rising of the pricing cycle there is the possibility that an altcoin will have a rise to 100x its starting price.
Taking profits from selling altcoins during the rise is important, but so is maintaining a reserve. In order to catch a 100x move, it may be worth the risk to put some of the altcoin on an exchange and set a very high limit order. For the larger cryptocurrencies like Bitcoin it is important to set trailing sell stops on the way up, and to not buy back in for at least a month if a sell stop gets triggered. Being able to read price charts, see support and resistance areas for price, and knowing how to set sell orders are an important part of mining profitability.

Actions to Take During the Cycle

As the cycle starts to rise from the bottom, this is a good time to buy mining hardware - it will be inexpensive. Also to mine and buy altcoins, which are usually the first to see a price rise, and will have larger price increases than Bitcoin.
On the rise of the cycle, this is a good time to see which altcoins are doing well from a project fundamentals standpoint, and which ones look like they are undergoing accumulation from investors.
Halfway through the rise of the cycle is the time to start selling altcoins for the larger project cryptos like Bitcoin. Miners will miss some of the profit at the top of the cycle, but will not run out of cash by doing this. This is also the time to stop buying mining hardware. Don’t worry, you’ll be able to pick up that same hardware used for a fraction of the price at the next bottom.
As the price nears the top of the cycle, sell enough Bitcoin and other cryptocurrencies to meet the following projected costs:
  • Mining electricity costs for the next 12 months
  • Planned investment into new miners for the next cycle
  • Additional funds needed for things like supporting a family or buying a Lambo
  • Taxes on all the capital gains from the sale of cryptocurrencies
It may be worth selling 70-90% of crypto holdings, maintaining a reserve in case there is second upward move caused by government bankruptcies. But selling a large part of the crypto is helpful to maintaining profitability and having enough cash reserves to make it through the bottom part of the next cycle.
As the cycle has peaked and starts to decline, this is a good time to start investing in mining facilities and other infrastructure, brush up on trading skills, count your winnings, and take some vacation.
At the bottom of the cycle, it is time to start buying both used and new mining equipment. The bottom can be hard to recognize.
If you can continue to mine all the way through bottom part of the cryptocurrency pricing cycle, paying with the funds sold near the top, you will have a profitable and enjoyable cryptocurrency mining business. Any cryptocurrency you are able to hold onto will benefit from the price progression in the next higher cycle phase.

An Update on Horizen - formerly ZenCash

The team at Horizen recognizes the important part that GPU miners played in the early success of Zclassic and ZenCash, and there is always a welcoming attitude to any of ZEN miners, past and present. About 1 year after ZenCash launched, ASIC miners became available for the Equihash algorithm. Looking at a chart of mining difficulty over time shows when it was time for GPU miners to move to mining other cryptocurrencies.

Horizen Historical Block Difficulty Graph
Looking at the hashrate chart, it is straightforward to see that ASIC miners were deployed starting June 2018. It appears that there was a jump in mining hashrate in October of 2017. This may have been larger GPU farms switching over to mine Horizen, FPGA’s on the network, or early version of Equihash ASIC miners that were kept private.
The team understands the importance of the cryptocurrency price cycle as it affects the funds from the Horizen treasury and the investments that can be made. 20% of each block mined is sent to the Horizen non-profit foundation for use to improve the project. Just like miners have to manage money, the team has to decide whether to spend funds when the price is high or convert it to another form in preparation for the bottom part of the cycle.
During the rise and upper part of the last price cycle Horizen was working hard to maximize the value of the project through many different ways, including spending on research and development, project management, marketing, business development with exchanges and merchants, and working to create adoption in all the countries of the world.
During the lower half of the cycle Horizen has reduced the team to the essentials, and worked to build a base of users, relationships with investors, exchanges, and merchants, and continue to develop the higher priority software projects. Lower priority software development, going to trade shows, and paying for business partnerships like exchanges and applications have all been completely stopped.
Miners are still a very important part of the Horizen ecosystem, earning 60% of the block reward. 20% goes to node operators, with 20% to the foundation. In the summer of 2018 the consensus algorithm was modified slightly to make it much more difficult for any group of miners to perform a 51% attack on Horizen. This has so far proven effective.
The team is strong, we provide monthly updates on a YouTube live stream on the first Wednesday of each month where all questions asked during the stream are addressed, and our marketing team works to develop awareness of Horizen worldwide. New wallet software was released recently, and it is the foundation application for people to use and manage their ZEN going forward.
Horizen is a Proof of Work cryptocurrency, and there is no plan to change that by the current development team. If there is a security or centralization concern, there may be change to the algorithm, but that appears unlikely at this time, as the hidden chain mining penalty looks like it is effective in stopping 51% attacks.
During 2019 and 2020 the Horizen team plans to release many new software updates:
  • Sidechains modification to main software
  • Sidechain Software Development Kit
  • Governance and Treasury application running on a sidechain
  • Node tracking and payments running on a sidechain
  • Conversion from blockchain to a Proof of Work BlockDAG using Equihash mining algorithm
After these updates are working well, the team will work to transition Horizen over to a governance model where major decisions and the allocation of treasury funds are done through a form of democratic voting. At this point all the software developed by Horizen is expected to be open source.
When the governance is transitioned, the project should be as decentralized as possible. The goal of decentralization is to enable resilience and preventing the capture of the project by regulators, government, criminal organizations, large corporations, or a small group of individuals.
Everyone involved with Horizen can be proud of what we have accomplished together so far. Miners who were there for the early mining and growth of the project played a large part in securing the network, evangelizing to new community members, and helping to create liquidity on new exchanges. Miners are still a very important part of the project and community. Together we can look forward to achieving many new goals in the future.

Continued censorship involving Ethereum's proposed fork to progPOW.

Our friends at Ethereum are subject to continued manipulation into forking their coin to progPOW. I decided to post this in /btc because it is the last bastion of free speech in the crypto community.
Today, after drawing attention to the sketchy history of progPOW's original proponent, my post was subjected to massive vote manipulation, and eventually deleted.
I have long suspected that progPOW favors NVIDIA miners, given the deep connections that progPOW's development team has to NVIDIA. Today, the progPOW team freely admitted that AMD miners will suffer a larger hashrate decrease compared to NVIDIA miners, so I created a poll:
Ethereum developers want to fork to ETH to progPOW [1], a proof-of-work algorithm that gives AMD GPUs a stronger hashrate penalty compared to NVIDIA [2][3]. Should Ethereum use ProgPOW for Proof-of-Work? Cast your vote with Ethereum [4].
Below is my post that was deleted, in its entirety.
If you are curious about the CSW/Coingeek connection, scroll down.
Previous Posts
Criticism and Soft Power
I have received criticism for my posts mostly due to what people call "character attacks." I have two things to say about that:
  1. I have never engaged in any character attacks. In all cases, the character has made their modus operandi known by themselves, and I have simply shined a light on it. I don't need call people "mentally unstable gentlemen" [--source, Ohgodagirl Twitter] to get my point across.
  2. Algorithm change discussions must include economic and political introspection as well as a discussion of the proposed change's technical details. As I have stated before, progPOW would not exist without the people responsible for creating it. We must look at these people's history, character, prior accomplishments, and industry connections. The discussion must exist outside the scope of the proposed change, not inside of it.
Example: When people criticize my posts for "not looking at the technical details", they are making a mistake. If someone asked "which should we kill more often: baby seals or baby kittens?", we don't all immediately start discussing the optimal relation of kittens-per-second to seals-per-second that can be killed. No, our first reaction is "what the fuck, why should we kill anything?"
Customer complaints from people who bought cloud contracts from Kristy's previous company:
Coingeek Connection
Previously, I had promised to provide information regarding the CSW/Coingeek and Core Scientific connection.
When I was president of (2003-2011), someone wanted to buy our company. When this happens, the buyer and seller usually write a purchase agreement similar to the business in which they are involved. This is done to ensure that the purchase is executed. In ImageShack's case, the buyer bought $500,000 worth of advertising from us. The logic was that ImageShack would be acquired, so they actually would pay themselves. If they didn't buy ImageShack, they would owe us $500,000.
Given the partnership between Core Scientific (Kristy's employer) and "Squire Mining" (effectively, Coingeek), I would not be surprised if Coingeek and Core Scientific made such an agreement, as well. In their case, it would likely be a hosting agreement. Since Coingeek has many ASICs, and Core Scientific is a large mining facility, I would not be surprised if those Coingeek ASICs are hosted by Core Scientific.
Individuals close to these parties can verify those claims, but I cannot share the proof at this time without revealing the identity of my sources.
Chatlog Dumps
Today, I also provide public comments from chatlog dumps showcasing Kristy Leigh Anne Minehan's deep connection to NVIDIA:

Profitable Crypto Mining: ASIC vs GPU, Which One Is Better?

Profitable Crypto Mining: ASIC vs GPU, Which One Is Better?
If you’re new to mining you probably have multiple questions running through your head right now. Good news is that it gets easier with time, assuming that you do your homework and research, and we will try to help you out.
One of the common questions is whether one should choose GPU or ASIC mining and we definitely have some advice on that topic.
When we’re considering classic POW mining we can quickly rule out CPU hardware for not being efficient and FPGA hardware because of its high costs. This leaves you with ASIC and GPU to choose from.

Buying Mining Equipment

Let’s get things straight — you won’t be able to buy ASIC devices in any of you local electronic shops, even in the biggest ones. There are two ways you can get this hardware: buying it online which shouldn’t be a problem these days unless that’s the newest model you’re after. Second option is to find a local company that sells ASIC equipment.
Also, you can try to purchase the equipment directly from the manufacture company, however, mind the huge customs and delivery fees if the company is located abroad.
It is highly recommended to test ASICs before buying them to make sure the equipment works properly.
GPU or graphics cards and other equipment that you will need to build your very own mining farm can be easily purchased at a regular computer store. The only problem you may have is getting the right set of hardware, so make sure to come prepared.
When buying a used (second-hand) graphics card don’t forget to test it.
What’s better?
If you’re not into hardware and have no clue how to set up a farm by yourself buying ASIC equipment would be a better option as you won’t need to build anything yourself.

Warranty Policy

In general, an official warranty policy for ASIC hardware is up to 180 days since the equipment was shipped to the buyer. When the seller is confident about the quality of their equipment, they can offer their personal 1 month warranty.
When you’re buying computer hardware in most of the cases you are getting full 2 year warranty policy including exchange or repairments of the equipment.
What’s better?
Warranty policy is especially important when you have no chance to check the equipment yourself or when you’re buying large inventory of it. Also, if you plan to go with overclocking, you will probably need a decent warranty as well.
We need to add that when you’re using the equipment accordingly and conduct regular maintenance both ASIC and GPU can work past the warranty period.

Setting Up Process

With ASICs it’s simple: you plug and connect it, pick a pool to join and start mining right away.
With GPU, it’s a little complicated. First, you need to build your farm. You will need a framework, motherboard with installed CPU and cooling, storage unit, power supply, risers and video cards. If you have no experience with assembling computer hardware you’re gonna need to save some time and prepare to put extra effort. Once your rig is ready you will have to install OS and optimize it which is usually even harder than setting up a rig. But luckily we’ve got a solution for that. CoinFly can do the work for you and help you with setting up and optimizing your equipment.
What’s better?
Although ASICs are very easy, you shouldn’t quickly give up on GPU mining. If assembling computer hardware is not a big problem for you, CoinFly will help you with setting it up.


ASIC equipment won’t give you too much trouble: it’s safe, stable, and doesn’t require any special knowledge. Maintenance includes cleaning off dust and oiling the fans.
When dealing with rigs, you will have to work a little harder and study the basics about at least graphics cards’ temperatures and operational frequency. A stable workflow depends heavily on the software and as it has a tendency to fail, it could become a problem. Unless you’re using CoinFly — our system will notify you in case of emergency so you can tune your equipment online.
What’s better?
Once again, when it comes to maintaining ASICs are almost trouble-free. GPU rigs are a bit tricky but when using the right tools like CoinFly to monitor their work, it can serve you just fine.

The Noise

ASICs are loud: when you’re in a room with a working ASIC you’re gonna need to shout, so people can hear you.
GPU farms have no such problem. Some of them are almost silent and that doesn’t affect the cooling process at all.
What’s better?
Maybe the level of noise your equipment makes was not the first issue on your list but we recommend you to consider it. ASICs are suitable only for the commercial and industrial premises.


ASICs can work with only one algorithm and mine one or several types of cryptocurrencies and are perfect for mining Bitcoin and its forks.
GPU rigs are universal: you can mine a huge variety of coins if you set your miner right.
What’s better?
If you want to mine Bitcoin, you gotta go with ASIC. But think again if that’s what you’re really after. After all, you can choose mining any altcoin that you’d like with your GPU rig and then simply exchange it to BTC. And if you’re lucky enough to mine a coin that will do good ASICs do not give you that choice, however, their mining capability is higher.

Relevance of the Equipment

ASICs are quickly getting out of date as the new models come along. Back in the day, the new versions used to come out every half a year and they were 10 times more efficient. In general, you need to change your ASIC hardware every year.
GPU equipment can perfectly serve you for 2 to 3 years and if you wish to sell the graphics card afterwards that wouldn’t be a problem either.
What’s better?
In terms of relevance, it’s probably reasonable to go with the GPU.

Return on Investment

In the long run, the profitableness of ASICs is higher but because the new models are being released quite frequently you cannot expect huge profits. It is always important to do your research and get the most relevant equipment.
GPU hardware will take its time to pay you back but it also depends if you manage to find the right coin to mine that will eventually increase your profits.
What’s better?
ASIC mining is definitely a good option for those who don’t want to constantly monitor the crypto market.
But in the case that you’re interested in what’s happening in the crypto space and you also have time to do your own research, the GPU farm would the better choice. If you’re not willing to spend your efforts on that, CoinFly Autopilot mode will help you mine the most profitable coin on the market automatically.


ASICs are great for people who can provide a non-residential space for mining and not willing to spend too much time and effort for setting up the equipment and stay updated with the latest trends in the crypto industry.
GPU rigs are suitable for mining at home and won’t scare away all the crypto and computer enthusiasts. If you’re just starting your mining journey but not sure how to do it, we recommend to register on CoinFly. From setting up your hardware to tuning it online and picking the best coin to mine at the moment — we’ve got you covered!

[Dev-Happy] BlondfrogsLast Friday at 3:58 PM
Hey everyone. The channel is now open for the dev meeting.
LSJI07 - MBITLast Friday at 3:58 PM
TronLast Friday at 3:59 PM
Hi all!
JerozLast Friday at 3:59 PM
TronLast Friday at 3:59 PM
Topics: Algo stuff - x22rc, Ownership token for Restricted Assets and Assets.
JerozLast Friday at 4:00 PM
@Milo is also here from coinrequest.
MiloLast Friday at 4:00 PM
Hi :thumbsup:
Pho3nix Monk3yLast Friday at 4:00 PM
welcome, @Milo
TronLast Friday at 4:00 PM
@Milo Was there PRs for Android and iOS?
MiloLast Friday at 4:01 PM
Yes, I've made a video. Give me a second I'll share it asap.
JerozLast Friday at 4:02 PM
I missed the iOS one.
MiloLast Friday at 4:02 PM
Well its 1 video, but meant for all.
JerozLast Friday at 4:02 PM
Ah, there's an issue but no pull request (yet?)
[Dev-Happy] BlondfrogsLast Friday at 4:03 PM
nice @Milo
MiloLast Friday at 4:04 PM
Can it be that I have no video post rights?
JerozLast Friday at 4:05 PM
In discord?
MiloLast Friday at 4:05 PM
[Dev-Happy] BlondfrogsLast Friday at 4:05 PM
just a link?
JerozLast Friday at 4:05 PM
Standard version has a file limit afaik
Pho3nix Monk3yLast Friday at 4:05 PM
try now
gave permissions
MiloLast Friday at 4:05 PM
it's not published yet on Youtube, since I didn't knew when it would be published in the wallets
file too big. Hold on i'll put it on youtube and set it on private
LSJI07 - MBITLast Friday at 4:06 PM
no worries ipfs it...:yum:
Pho3nix Monk3yLast Friday at 4:06 PM
ok, just send link when you can
[Dev-Happy] BlondfrogsLast Friday at 4:07 PM
So guys. We released Ravencoin v2.4.0!
JerozLast Friday at 4:08 PM
If you like the code. Go update them nodes! :smiley:
[Dev-Happy] BlondfrogsLast Friday at 4:08 PM
We are recommending that you are upgrading to it. It fixes a couple bugs in the code base inherited from bitcoin!
MiloLast Friday at 4:08 PM\_g7NpFXm6g&
sorry for the hold up
Coin Request
Raven dev Gemiddeld
LSJI07 - MBITLast Friday at 4:09 PM
thanks short and sweet!!
KAwARLast Friday at 4:10 PM
Is coin request live on the android wallet?
TronLast Friday at 4:10 PM
Nice video.
It isn't in the Play Store yet.
Pho3nix Monk3yLast Friday at 4:10 PM
Well, this is the first time in a while where we have this many devs online. What questions do y'all have?
LSJI07 - MBITLast Friday at 4:11 PM
Algo questions?
Pho3nix Monk3yLast Friday at 4:11 PM
KAwARLast Friday at 4:11 PM
LSJI07 - MBITLast Friday at 4:12 PM
what are the proposed 22 algos in x22r? i could only find the original 16 plus 5 on x21.
TronLast Friday at 4:12 PM
Likely the 5 from x21 and find one more.
We need to make sure they're all similar in time profile.
liqdmetalLast Friday at 4:14 PM
should we bother fixing a asic-problem that we dont know exists for sure or not?
TronLast Friday at 4:14 PM
That's the 170 million dollar question.
[Dev-Happy] BlondfrogsLast Friday at 4:14 PM
I would prefer to be proactive not reactive.
JerozLast Friday at 4:14 PM
LSJI07 - MBITLast Friday at 4:15 PM
RIPEMD160 is a golden oldie but not sure on hash speed compared to the others.
liqdmetalLast Friday at 4:15 PM
in my mind we should focus on the restricted messaging etc
Sevvy (y rvn pmp?)Last Friday at 4:15 PM
probably won't know if the action was needed until after you take the action
liqdmetalLast Friday at 4:15 PM
we are at risk of being interventionistas
acting under opacity
TronLast Friday at 4:15 PM
Needs to spit out at least 256 bit. Preferably 512 bit.
LSJI07 - MBITLast Friday at 4:15 PM
TronLast Friday at 4:15 PM
If it isn't 512 bit, it'll cause some extra headache for the GPU mining software.
liqdmetalLast Friday at 4:16 PM
i seek to avoid iatrogenics
TronLast Friday at 4:16 PM
Similar to the early problems when all the algos except the first one were built for 64-bytes (512-bit) inputs.
Had to look that one up. TIL iatrogenics
JerozLast Friday at 4:17 PM
I have to google most of @liqdmetal's vocabulary :smile:
liqdmetalLast Friday at 4:17 PM
@Tron tldr: basically the unseen, unintended negative side effects of the asic "cure"
Sevvy (y rvn pmp?)Last Friday at 4:18 PM
10 dolla word
liqdmetalLast Friday at 4:19 PM
we need a really strong case to intervene in what has been created.
TronLast Friday at 4:19 PM
I agree. I'm less concerned with the technical risk than I am the potential split risk experienced multiple times by Monero.
Sevvy (y rvn pmp?)Last Friday at 4:20 PM
tron do you agree that forking the ravencoin chain presents unique risks compared to other chains that aren't hosting assets?
JerozLast Friday at 4:21 PM
Yes, if you fork, you need to figure out for each asset which one you want to support.
Sevvy (y rvn pmp?)Last Friday at 4:21 PM
yeah. and the asset issuer could have a chain preference
TronLast Friday at 4:22 PM
@Sevvy (y rvn pmp?) Sure. Although, I'd expect that the asset issuers will be honor the assets on the dominant chain. Bigger concern is the branding confusion of multiple forks. See Bitcoin, Bitcoin Cash, Bitcoin SV for an example. We know they're different, but do non-crypto folks?
Hans_SchmidtLast Friday at 4:22 PM
I thought that the take-away from the recently published analyses and discussions was that ASICs for RVN may be active, but if so then they are being not much more effective than GPUs.
Sevvy (y rvn pmp?)Last Friday at 4:22 PM
agreed on all accounts there tron
TronLast Friday at 4:23 PM
I'm not yet convinced ASICs are on the network.
KAwARLast Friday at 4:23 PM
It would be better to damage an asic builder by forking after they made major expenses. Creating for them the type of deficit that could be negated by just buying instead of mining. Asic existence should be 100 percent confirmed before fork.
liqdmetalLast Friday at 4:23 PM
170million dollar question is
TronLast Friday at 4:24 PM
I've had someone offer to connect me to the folks at Fusion Silicon.
Sevvy (y rvn pmp?)Last Friday at 4:25 PM
yes. and if they are active on the network they are not particularly good ASICs
which makes it a moot point probably
TronLast Friday at 4:26 PM
The difficult part of this problem is that by the time everyone agrees that ASICs are problematic on the network, then voting the option in is likely no longer an option.
Sevvy (y rvn pmp?)Last Friday at 4:26 PM
yes. part of me wonders if we would say "okay, the clock on the asic countdown is reset by this new algo. but now the race is on"
[Dev-Happy] BlondfrogsLast Friday at 4:26 PM
There are always risks when making a change that will fork the network. We want wait to long though, as tron said. It wont be a voting change. it will be a mandatory change at a block number.
Sevvy (y rvn pmp?)Last Friday at 4:26 PM
acknowledge the inevitable
MiloLast Friday at 4:27 PM
I had just a small question from my side. When do you think the android version would be published, and do you maybe have a time-frame for the others?
TronLast Friday at 4:27 PM
Quick poll. How would everyone here feel about a BIP9 option - separate from the new features that can be voted in?
KAwARLast Friday at 4:27 PM
Maybe voting should not be a strictly blockchain vote. A republic and a democratic voice?
[Dev-Happy] BlondfrogsLast Friday at 4:27 PM
@Milo We can try and get a beta out next week, and publish soon after that.
MiloLast Friday at 4:28 PM
@[Dev-Happy] Blondfrogs :thumbsup::slight_smile:
[Dev-Happy] BlondfrogsLast Friday at 4:28 PM
BIP9 preemptive vote. I like it.
TronLast Friday at 4:30 PM
The advantage to a BIP9 vote is that it puts the miners and mining pools at a clear majority before activation.
LSJI07 - MBITLast Friday at 4:30 PM
Centralisation is inevitable unless we decide to resist it. ASIC's are market based and know the risks and rewards possible. A key step in resisting is sending a message. An algo change to increase asic resistance is imho a strong message. A BIP9 vote now would also be an indicator of bad actors early....
TronLast Friday at 4:30 PM
The disadvantage is that it may not pass if the will isn't there.
LSJI07 - MBITLast Friday at 4:30 PM
Before assets are on main net and cause additional issues.
KAwARLast Friday at 4:31 PM
I am not schooled in coding to have an educated voice. I only understand social problems and how it affects the economy.
SpyderDevLast Friday at 4:31 PM
All are equal on RVN
TronLast Friday at 4:31 PM
It is primarily a social problem. The tech change is less risky and is easier than the social.
LSJI07 - MBITLast Friday at 4:32 PM
All can have a share....people who want more of a share however pay for the privilege and associated risks.
KAwARLast Friday at 4:33 PM
Assets and exchange listings need to be consistent and secure.
brutoidLast Friday at 4:36 PM
I'm still not entirely clear on what the overall goal to the algo change is? Is it just to brick the supposed ASICs (unknown 45%) which could still be FPGAs as seen from the recent block analysis posted in the nest. Is the goal to never let ASICs on? Is it to brick FPGAs ultimately. Are we making Raven strictly GPU only? I'm still unclear
LSJI07 - MBITLast Friday at 4:37 PM
What about the future issue of ASICs returning after a BIP9 fork "soon"? Are all following the WP as a community? i.e asic resistant or are we prepared to change that to asic resistant for early coin emission. Ideally we should plan for the future. Could the community make a statement that no future algo changes will be required to incentivise future public asic manufacturers?
Lol. Same question @brutoid
brutoidLast Friday at 4:37 PM
Haha it is
You mind-beamed me!
[Dev-Happy] BlondfrogsLast Friday at 4:38 PM
The is up to the community.
Currently, the feel seems like the community is anti asic forever.
The main issue is getting people to upgrade.
KAwARLast Friday at 4:38 PM
Clarity is important. Otherwise we are attacking windmills like Don Quixote.
brutoidLast Friday at 4:39 PM
I'm not getting the feeling of community ASIC hate if the last few weeks of discussion are anything to go by?
Hans_SchmidtLast Friday at 4:39 PM
A unilateral non-BIP9 change at a chosen block height is a serious thing, but anti-ASIC has been part of the RVN philosophy since the whitepaper and is therefore appropriate for that purpose.
[Dev-Happy] BlondfrogsLast Friday at 4:39 PM
We can use the latest release as an example. It was a non forking release, announced for 2 weeks. and only ~30% of the network has upgraded.
TronLast Friday at 4:39 PM
@Hans_Schmidt Well said.
liqdmetalLast Friday at 4:40 PM
I'm not concerned about a "asic hardware problem" so much as I believe it more likely what we are seeing is several big fish miners (perhaps a single really big fish). For now I recommend standing pat on x16r. In the future I can see an algo upgrade fork to keep the algo up to date. If we start fighting against dedicated x16r hashing machines designed and built to secure our network we are more likely to go down in flames. The custom SHA256 computers that make the bitcoin the most secure network in existence are a big part of that security. If some party has made an asic that performs up to par or better than FPGA or GPU on x16r, that is a positive for this network, a step towards SHA256 security levels. It is too bad the community is in the dark regarding their developments. Therefore I think the community has to clarify its stance towards algorithm changes. I prefer a policy that will encourage the development of mining software, bitstreams and hardware by as many parties as possible. The imminent threat of ALGO fork screws the incentive up for developers.
JerozLast Friday at 4:40 PM
@brutoid the vocal ones are lenient towards asics, but the outcome of the 600+ votes seemed pretty clear.
brutoidLast Friday at 4:40 PM
This is my confusion
TronLast Friday at 4:41 PM
More hashes are only better if the cost goes up proportionally. Machines that do more hashes for less $ doesn't secure the network more, and trends towards centralization.
JerozLast Friday at 4:41 PM
I would argue for polling ever so often as it certainly will evolve dynamically with the state of crypto over time.
TronLast Friday at 4:41 PM
Measure security in two dimensions. Distribution, and $/hash.
liqdmetalLast Friday at 4:41 PM
and volume of hash
traysiLast Friday at 4:42 PM
45% of the hashrate going to one party is unhealthy, and standing pat on x16r just keeps that 45% where it is.
TronLast Friday at 4:42 PM
Volume doesn't matter if the cost goes down. For example, lets say software shows up that does 1000x better than the software from yesterday, and everyone moves to it. That does not add security. Even if the "difficulty" and embedded hashes took 1000x more attempts to find.
brutoidLast Friday at 4:42 PM
My issue is defintely centralization of hash and not so much what machine is doing it. I mine with both GPU and FPGA. Of course, the FPGAs are not on raven
TJayLast Friday at 4:44 PM
easy solution is just to replace a few of 16 current hash functions, without messing with x21r or whatever new shit
TronLast Friday at 4:44 PM
How do folks here feel about allowing CPUs back in the game?
traysiLast Friday at 4:44 PM
Botnets is my concern with CPUs
brutoidLast Friday at 4:44 PM
Botnets is my concern
SpyderDevLast Friday at 4:44 PM
Yes please.
LSJI07 - MBITLast Friday at 4:44 PM
the poll votes seem not very security conscious. More of day miners chasing profits. I love them bless! Imho the future is bright for raven, however these issues if not sorted out now will bite hard long term when asset are on the chain and gpu miners are long gone.....
ZaabLast Friday at 4:45 PM
How has the testing of restricted assets been on the test net?
liqdmetalLast Friday at 4:45 PM
Agreed. I dont think x16r is obsolete like that yet however
[Dev-Happy] BlondfrogsLast Friday at 4:45 PM
@Zaab not enough testing at the moment.
HedgerLast Friday at 4:45 PM
Yes, how is the Testing going?
justinjjaLast Friday at 4:45 PM
Like randomX or how are cpus going to be back in the game?
TronLast Friday at 4:45 PM
@Zaab Just getting started at testing at the surface level (RPC calls), and fixing as we go.
ZaabLast Friday at 4:45 PM
And or any updates on the review of dividend code created by the community
Lokar -=Kai=-Last Friday at 4:45 PM
if the amount of hash the unknown pool has is fixed as standarderror indicated then waiting for the community of FPGAers to get onto raven might be advantageous if the fork doesn't hurt FPGAs.
ZaabLast Friday at 4:45 PM
Can't rememeber who was on it
SpyderDevLast Friday at 4:45 PM
@Zaab But we are working on it...
Lokar -=Kai=-Last Friday at 4:46 PM
more hash for votes
JerozLast Friday at 4:46 PM
@Maldon is, @Zaab
TronLast Friday at 4:46 PM
@Zaab There are unit tests and functional tests already, but we'd like more.
[Dev-Happy] BlondfrogsLast Friday at 4:46 PM
@Zaab Dividend code is currently adding test cases for better security. Should have more update on that next meeting
KAwARLast Friday at 4:46 PM
Absolute democracy seems to resemble anarchy or at least civil war. In EVE online they have a type of community voice that get voted in by the community.
ZaabLast Friday at 4:46 PM
No worries was just curious if it was going as planned or significant issues were being found
Obviously some hiccups are expected
More testing is always better!
TronLast Friday at 4:47 PM
Who in here is up for a good civil war? :wink:
ZaabLast Friday at 4:47 PM
Tron v Bruce. Celebrity fight night with proceeds to go to the RVN dev fund
SpyderDevLast Friday at 4:48 PM
Cagefight or mudpit?
JerozLast Friday at 4:48 PM
talking about dev funds..... :wink:
Pho3nix Monk3yLast Friday at 4:49 PM
and there goes the conversation....
KAwARLast Friday at 4:49 PM
I am trying to be serious...
ZaabLast Friday at 4:49 PM
Sorry back to the ascii topic!
traysiLast Friday at 4:49 PM
@Tron What do we need in order to make progress toward a decision on the algo? Is there a plan or a roadmap of sorts to get us some certainty about what we're going to do?
LSJI07 - MBITLast Friday at 4:50 PM
Could we have 3 no BIP9 votes? No1 Friendly to asics, retain status quo. No2 change to x17r minimal changes etc, with no additional future PoW/algo upgrades. No3. Full Asic resistance x22r and see what happens...
Sounds messy....
TronLast Friday at 4:51 PM
Right now we're in research mode. We're building CNv4 so we can run some metrics. If that goes well, we can put together x22rc and see how it performs. It will likely gore everyone's ox. CPUs can play, GPUs work, but aren't dominant. ASICs VERY difficult, and FPGAs will have a tough time.
ZaabLast Friday at 4:51 PM
Yeah i feel like the results would be unreliable
TronLast Friday at 4:51 PM
Is this good, or do we lose everyone's vote?
PlayHardLast Friday at 4:52 PM
Fpga will be dead
Lokar -=Kai=-Last Friday at 4:52 PM
why isn;t a simple XOR or something on the table?
ZaabLast Friday at 4:52 PM
The multiple bip9 that is
Lokar -=Kai=-Last Friday at 4:52 PM
something asic breaking but doesn't greatly complicate ongoing efforts for FPGA being my point.
justinjjaLast Friday at 4:52 PM
How are you going to vote for x22rc?
Because if by hashrate that wouldn't pass.
traysiLast Friday at 4:52 PM
Personally I like the idea of x22rc but I'd want to investigate the botnet threat if CPUs are allowed back in.
TronLast Friday at 4:52 PM
XOR is on the table, and was listed in my Medium post. But, the social risk of chain split remains, for very little gain.
traysiLast Friday at 4:53 PM
@Lokar -=Kai=- A small change means that whoever has 45% can probably quickly adapt.
LSJI07 - MBITLast Friday at 4:53 PM
Research sounds good. x22rc could be reduce to x22r for simplicity...
TronLast Friday at 4:53 PM
x22r is a viable option. No CNv4.
LSJI07 - MBITLast Friday at 4:53 PM
Don't know how much time we have to play with though...
Lokar -=Kai=-Last Friday at 4:53 PM
if they have FPGAs yes if they have ASIC then not so much, but I guess that gets to the point, what exactly are we trying to remove from the network?
PlayHardLast Friday at 4:54 PM
Guys my name is Arsen and we designed x16r fpga on bcus. Just about to release it to the public. I am buzzdaves partner.
Will kill us
But agreed
Asic is possible on x16r
And you dont need 256 core
traysiLast Friday at 4:55 PM
Hi Arsen. Are you saying CN will kill "us" meaning RVN, or meaning FPGA?
JerozLast Friday at 4:55 PM
This is what im afraid of ^ an algo change killing FPGA as I have the feeling there is a big fpga community working on this
PlayHardLast Friday at 4:55 PM
Fpgas ))
whitefire990Last Friday at 4:55 PM
I am also about to release X16R for CVP13 + BCU1525 FPGA's. I'm open to algo changes but I really don't believe in CPU mining because of botnets. Any CNv4 shifts 100% to CPU mining, even if it is only 1 of the 22 functions.
Lokar -=Kai=-Last Friday at 4:55 PM
namely FPGAs that aren;t memory equipped
like fast mem
not ddr
PlayHardLast Friday at 4:55 PM
Hbm non hbm
whitefire990Last Friday at 4:56 PM
Right now with both Buzzdave/Altered Silicon and myself (Zetheron) about to release X16R for FPGA's, then the 45% miner's share will decrease to 39% or less.
PlayHardLast Friday at 4:56 PM
Will be dead for fpga
LSJI07 - MBITLast Friday at 4:56 PM
sound so x22r is fpga "friendly" ... more so than asic anyway...
PlayHardLast Friday at 4:56 PM
But a change must be planned
X16r is no way possible to avoid asics
TJayLast Friday at 4:56 PM
@LSJI07 - MBIT I would say less friendly...
whitefire990Last Friday at 4:57 PM
As I mentioned in thenest discussion, asic resistance increases with the square of the number of functions, so X21R is more asic resistant than X16R, but both are pretty resistant
PlayHardLast Friday at 4:58 PM
Yeah more algos make it heavier on ASIC
DirkDiggler (Citadel Architect)Last Friday at 4:58 PM
My interpretation of the whitepaper was that we used x16r as it was brand new (thus ASIC resistant), and that was to ensure a fair launch... We've launched... I don't like the idea of constantly forking to avoid the inevitable ASICs.
x16r was a great "experiment" before we had any exchange listings... that ship has sailed though... not sure about all these x22rs lmnop changes
KAwARLast Friday at 5:00 PM
I believe that it is easier to change the direction of a bicycle than an oil tanker. We feel more like a train. We should lay out new tracks and test on them and find benefits that are acceptable to everyone except train robbers. Then open the new train station with no contentious feelings except a silently disgruntled minority group. ???
Hans_SchmidtLast Friday at 5:01 PM
The most productive action the community can do now re ASICs is to voice support for the devs to make a non-BIP9 change at a chosen block height if/when the need is clear. That removes the pressure to act rashly to avoid voting problems.
LSJI07 - MBITLast Friday at 5:01 PM
Thats why im proposing to fork at least once to a more asic resistant algo (but FPGA "friendly/possible"), with the proviso ideally that no more PoW algo forks are require to provide future ASICs some opportunity to innovate with silicon and efficiency.
TJayLast Friday at 5:01 PM
folks should take into account, that high end FPGAs like BCU1525 on x16r can't beat even previous gen GPUs (Pascal) in terms of hash cost. so they aren't a threat to miners community
PlayHardLast Friday at 5:02 PM
A proper change
Requires proper research
eyz (Silence)Last Friday at 5:02 PM
Just so I'm clear here, we are trying to boot ASICS, don't want CPUs because of Botnets, and are GPU and FPGA friendly right?
PlayHardLast Friday at 5:02 PM
It is not a quick one day process
eyz (Silence)Last Friday at 5:02 PM
If there is a bip9 vote there needs to be a clear explanation as I feel most in the community don't understand exactly what we are trying to fix
TronLast Friday at 5:03 PM
@Hans_Schmidt I like that route. It has some game theoretics. It gives time for miners to adapt. It is only used if needed. It reduces the likelihood of ASICs dominating the network, or even being built.
[Dev-Happy] BlondfrogsLast Friday at 5:03 PM
Hey guys. great convo. We are of course looking to do the best thing for the community and miner. We are going to be signing off here though.
justinjjaLast Friday at 5:03 PM
TJay that comes down to power cost.
If your paying 4c/kw gpus all the way.
But if your a home miner in europe an fpga is your only chance

Mining ERC-918 Tokens (0xBitcoin)


0xBitcoin (0xBTC) is the first mineable ERC20 token on Ethereum. It uses mining for distribution, unlike all previous ERC20 tokens which were assigned to the contract deployer upon creation. 0xBTC is the first implementation of the EIP918 mineable token standard (, which opened up the possibility of a whole new class of mineable assets on Ethereum. Without any ICO, airdrop, pre-mine, or founder’s reward, 0xBitcoin is arguably the most decentralized asset in the Ethereum ecosystem, including even Ether (ETH), which had a large ICO.
The goal of 0xBitcoin is to be looked at as a currency and store of value asset on Ethereum. Its 21 million token hard cap and predictable issuance give it scarcity and transparency in terms of monetary policy, both things that Ether lacks. 0xBitcoin has certain advantages over PoW based currencies, such as compatibility with smart contracts and decentralized exchanges. In addition, 0xBTC cannot be 51% attacked (without attacking Ethereum), is immune from the “death spiral”, and will receive the benefits of scaling and other improvements to the Ethereum network.


0xBitcoin can be mined using typical PC hardware, traded on exchanges (either decentralized or centralized) or purchased from specific sites/contracts.

-Mined using PC hardware

-Traded on exchanges such as


0xBitcoin is a Smart Contract on the Ethereum network, and the concept of Token Mining is patterned after Bitcoin's distribution. Rather than solving 'blocks', work is issued by the contract, which also maintains a Difficulty which goes up or down depending on how often a Reward is issued. Miners can put their hardware to work to claim these rewards, in concert with specialized software, working either by themselves or together as a Pool. The total lifetime supply of 0xBitcoin is 21,000,000 tokens and rewards will repeatedly halve over time.
The 0xBitcoin contract was deployed by Infernal_Toast at Ethereum address: 0xb6ed7644c69416d67b522e20bc294a9a9b405b31
0xBitcoin's smart contract, running on the Ethereum network, maintains a changing "Challenge" (that is generated from the previous Ethereum block hash) and an adjusting Difficulty Target. Like traditional mining, the miners use the SoliditySHA3 algorithm to solve for a Nonce value that, when hashed alongside the current Challenge and their Minting Ethereum Address, is less-than-or-equal-to the current Difficulty Target. Once a miner finds a solution that satisfies the requirements, they can submit it into the contract (calling the Mint() function). This is most often done through a mining pool. The Ethereum address that submits a valid solution first is sent the 50 0xBTC Reward.
(In the case of Pools, valid solutions that do not satisfy the full difficulty specified by the 0xBitcoin contract, but that DO satisfy the Pool's specified Minimum Share Difficulty, get a 'share'. When one of the Miners on that Pool finds a "Full" solution, the number of shares each miner's address has submitted is used to calculate how much of the 50 0xBTC reward they will get. After a Reward is issued, the Challenge changes.
A Retarget happens every 1024 rewards. In short, the Contract tries to target an Average Reward Time of about 60 times the Ethereum block time. So (at the time of this writing):
~13.9 seconds \* 60 = 13.9 minutes
If the average Reward Time is longer than that, the difficulty will decrease. If it's shorter, it will increase. How much longer or shorter it was affects the magnitude with which the difficulty will rise/drop, to a maximum of 50%. * Click Here to visit the stats page~ ( to see recent stats and block times, feel free to ask questions about it if you need help understanding it.


Presently, 0xBitcoin and "Alt Tokens" can be mined on GPUs, CPUs, IGPs (on-CPU graphics) and certain FPGAs. The most recommended hardware is nVidia graphics cards for their efficiency, ubiquity and relatively low cost. As general rules, the more cores and the higher core frequency (clock) you can get, the more Tokens you will earn!

Ritocoin - a 100% community driven project based on Ravencoin

tl:dr: Ritocoin is a code fork of the Ravencoin codebase and continues to track future Ravencoin developments. The project was launched to provide a more community-oriented blockchain with the same functionality as Ravencoin, without a corporate overseer, and with a more flexible model for community participation and development. It’s intention is to be a hacker’s playground for innovative ideas.


Proof-of-Work Algorithm: X21S
Block Time: 60 seconds
POW Block Reward: Smooth curve down
Community fund: 1% first year
Difficulty Retargeting: DGW-180
Maximum Supply:
6 months: 993,521,892 RITO
1 year: 1,227,448,858 RITO
5 years: 1,762,210,058 RITO
10 years: 1,820,404,381 RITO
50 years: 2,030,907,256 RITO
100 years: 2,293,707,246 RITO
Infinite: 10 RITO per block in perpetuity

Pre-mine: None
Masternodes: Researching for use case
Asset layer: Was enabled at height 50,000



This hashing algorithm was created specifically for Ritocoin, and was designed to resist FPGAs, ASICs, and NiceHash. It is X16S (16 algorithms shuffled and hashed),, followed by 5 additional hashing algorithms: haval256, tiger, lyra2, gost512, and sha256. The inclusion of lyra2 brings numerous advantages, making parallelization of the algorithm practically impossible, with each step relying on the previous step having already been computed. It is a “friendly” algorithm that makes GPUs produce much less heat and uses less electricity during mining.

Take your time to learn more about us in the below story of Ritocoin...

The spirit of Bitcoin continues to inspire, empower and enable people around the globe. Ten years later, just as it seemed Bitcoin was being defined by commercial agents and regulated governance, that same free and independent spirit imbued the Ravencoin community. In ten short months, however, 30% of the Ravencoin project’s net hash comes from NiceHash and the looming impact of the imminent FPGA mining cards and X16R bitstreams certainly promises to shake up the dream of this GPU miner’s darling.

Ravencoin’s fair launch genuinely inspired our developers and supporters. We admire the way Ravencoin came out swinging — fighting for fairness, an honest distribution of coins and a place where GPU miners could thrive. The asset layer attracted many more miners and investors to the pools. Many Ritocoin enthusiasts came from the Ravencoin community, and continue their association with that project.

The whole crypto ecosystem should appreciate the work begun by Ravencoin. Obviously they continue to inspire and motivate us to this day. It’s the reason we took action. We decided to start our own project which focuses upon at least two pillars of decentralized networks in the crypto space: community governance and a fair distribution of coins. It is a core belief throughout Ritocoin that in order to successfully develop and maintain this hacker’s playground — a place where a broad range of ideas could be tried and allowed to flourish — these two ideals must be allowed to drive and guide our community.

This deep focus on community choices creates a project flexible enough to support most ideas, and agile enough to define new frontiers.

A mining network’s distributed ledger is defined by its technology. Like many in the broader crypto-mining community, we value the GPU for its accessibility. These processors are available for purchase all around the world without any legal restrictions. GPUs are vastly more accessible for hobbyists and miners to acquire. They can be shipped nearly anywhere around the globe, a nice benefit to the popular secondary market which has sprung up much to the chagrin of PC gamers.

More constraints exist for the ASIC and FPGA miner. Laws in some parts of the world restrict people from using or buying ASIC and FPGA mining hardware. This alone is directly in confrontation with Ritocoin’s core values of decentralized stewardship and sovereignty.

The GPU, in essence, is like your voice. Anyone with the means of acquiring one GPU should be able to have their voice heard. ASIC and FPGA mining devalues the GPU miner’s voice and silos that coin’s network away from the small scale and personal mining operator. A truly community driven project means each stakeholder, regardless of size of contribution to the network’s net hash, has an opportunity to build, vote and direct.

If you are already familiar with our website, discord or whitepaper, you are probably aware that masternodes had been proposed as a feature of the network from the beginning. This opened the door to ongoing discussions in the Ritocoin community regarding

● A masternode’s true purpose

● What benefit they provide to the project

● How the benefit is realized

● The collateral

This discussion, governed entirely by stakeholders across the extended network yielded a defining moment for our vision of flexibility. We have not yet found the potential utility of masternodes, however, the conversation has not reached an extent to where we could abandon the idea. To quote one of our developers during this discussion on our Discord:

“Just want to give a reminder here that even though masternodes are on the roadmap, it is not set in stone. This coin belongs to the community and we will do what we as a community want to do. If we conclude that we want to take this coin a different direction than masternodes, then that is what we’ll do.” --traysi

We are all volunteers at Ritocoin. Our moderators and community leaders try to give immediate support to all users that require it. Contact us in Discord or Telegram, not only for support, but, proposing new ideas, revising old ones and just so you can find a place to get together and find people to hang out with. You are well within your rights to enjoy yourself at any given moment, and, should you feel so inclined to begin working with the team, we just so happen to be looking for ambitious individuals that see themselves as being part of a greater vision, are inspired by change, and inspired to be the change they want to see making things better in this world.

Join us in a space where your ideas to build something great can become a reality. We are eager to know what you think is best for the future of Rito. What steps would you take to become more resilient, stronger, fair and decentralized? Because at the end of the day, like it or not, love it or leave it.. this is your coin, too.

You can become a significant part of this project. We will help you further develop the role you wish to fill in the cryptocurrency space — influencer, developer, analyst, you name it. This is not a just-for-developer’s playground. We want the enthusiasts. We want the perplexed and the rabbit-hole divers. This is the coin for everyone who is trying to find their place on the path that Satoshi began unfolding in 2008 after the collapse of the housing market rippled out into the subsequent crash of global markets. That’s why we have Bitcoin, remember? Be your own bank. This is why Satoshi and kept their software open source. It’s up to us to keep the torch ablaze.

Community funds

For the first year, about 1% of mined coins are set aside into a developers fund that is used to provide bounties to the community developers who make substantial development contributions to the Ritocoin ecosystem. We have already paid out numerous bounties for important work that has already benefits Ritocoin in substantial ways. We also have another donation-driven community fund that has recently been put together for the purposes of doing fun contests and things like that.

Cooperation and collaborations

We have discovered a number of fatal flaws in the original Ravencoin codebase and worked with the Ravencoin developers to get those fixed in both Ritocoin and Ravencoin. This work has benefitted Ravencoin in numerous ways and we look forward to a long time of collaboration and cooperation between us and them. Many members of the Safecoin team are also in our discord group, and have collaborated with us in shaping the future decisions of Ritocoin. We have several thousand members in our group and they represent all walks of cryptocurrency life. We invite all coin developers, miners and enthusiasts to join our discord and be a part of this coin that truly belongs entirely to the community.

Block reward

A couple weeks ago we met for a scheduled meeting in our discord group and had a lengthy conversation about the block reward. Our block reward started at 5,000 RITO per block (every 60 seconds) just like Ravencoin. This extremely high number of coins coupled with the high profitability of mining led to unforeseen consequences with pools auto-exchanging the coin into bitcoin. This dumping by non-community miners had a very negative impact on the community sentiment and morale, as we watched the exchange price plunge. We looked at other coins and realized that this fate has befell many other coins with high block rewards. Following much discussion, we decided to change the reward structure. Starting around March 19th the block rewards will start to slowly go down in a curve until it reaches 1,000. Then the reduction will be even more slowed down with block rewards exponentially dropping at periodic intervals. We have posted charts on our website that shows what the long-term effects of our reward reducing algorithms will be. As a miner, the next 2 months will be a great time to mine and hold, while the block reward is still fairly high. We encourage all miners and cryptocurrency enthusiasts to take advantage of the current favourable block reward and build a nice holding for yourself. Then join the community and be a part of the fun we’re having with this project.
This post was prepared by a collaboration of multiple Ritocoin members and was posted to reddit by the core developer Trevali, who posts to reddit under the ritocoin username and will be very happy to answer any questions anybody may have about our project. Traysi (well known in the Ravencoin community) is also an active Ritocoin developer and may come to this thread if needed.
We welcome any questions from any of you regarding our project!

Best $100-$300 FPGA development board in 2018?

Hello, I’ve been trying to decide on a FPGA development board, and have only been able to find posts and Reddit threads from 4-5 years ago. So I wanted to start a new thread and ask about the best “mid-range” FGPA development board in 2018. (Price range $100-$300.)
I started with this Quora answer about FPGA boards, from 2013. The Altera DE1 sounded good. Then I looked through the Terasic DE boards.
Then I found this Reddit thread from 2014, asking about the DE1-SoC vs the Cyclone V GX Starter Kit:‬ (I was also leaning towards the DE1-SoC.)
Anyway, I thought I better ask here, because there are probably some new things to be aware of in 2018.
I’m completely new to FPGAs and VHDL, but I have experience with electronics/microcontrollers/programming. My goal is to start with some basic soft-core processors. I want to get some C / Rust programs compiling and running on my own CPU designs. I also want to play around with different instruction sets, and maybe start experimenting with asynchronous circuits (e.g. clock-less CPUs)
Also I don’t know if this is possible, but I’d like to experiment with ternary computing, or work with analog signals instead of purely digital logic. EDIT: I just realized that you would call those FPAAs, i.e. “analog” instead of “gate”. Would be cool if there was a dev board that also had an FPAA, but no problem if not.
EDIT 2: I also realized why "analog signals on an FPGA" doesn't make any sense, because of how LUTs work. They emulate boolean logic with a lookup table, and the table can only store 0s and 1s. So there's no way to emulate a transistor in an intermediate state. I'll just have play around with some transistors on a breadboard.
UPDATE: I've put together a table with some of the best options:
Board Maker Chip LUTs Price SoC? Features
icoBoard Lattice iCE40-HX8K 7,680 $100 Sort of A very simple FPGA development board that plugs into a Raspberry Pi, so you have a "backup" hard-core CPU that can control networking, etc. Supports a huge range of pmod accessories. You can write a program/circuit so that the Raspberry Pi CPU and the FPGA work together, similar to a SoC. Proprietary bitstream is fully reverse engineered and supported by Project IceStorm, and there is an open-source toolchain that can compile your hardware design to bitstream. Has everything you need to start experimenting with FPGAs.
iCE40-HX8K Breakout Board Lattice iCE40-HX8K-CT256 7,680 $49 No 8 LEDs, 8 switches. Very similar to icoBoard, but no Raspberry Pi or pmod accessories.
iCE40 UltraPlus Lattice iCE40 UltraPlus FPGA 5280 $99 No Chip specs. 4 switchable FPGAs, and a rechargeable battery. Bluetooth module, LCD Display (240 x 240 RGB), RGB LED, microphones, audio output, compass, pressure, gyro, accelerometer.
Go Board Lattice ICE40 HX1K FPGA 1280 $65 No 4 LEDs, 4 buttons, Dual 7-Segment LED Display, VGA, 25 MHz on-board clock, 1 Mb Flash.
snickerdoodle Xilinx Zynq 7010 28K $95 Yes Xilinx Zynq 7-Series SoC - ARM Cortex-A9 processor, and Artix-7 FPGA. 125 IO pins. 1GB DDR2 RAM. Texas Instruments WiLink 8 wireless module for 802.11n Wi-Fi and Bluetooth 4.1. No LEDs or buttons, but easy to wire up your own on a breadboard. If you want to use a baseboard, you'll need a snickerdoodle black ($195) with the pins in the "down" orientation. (E.g. The "breakyBreaky breakout board" ($49) or piSmasher SBC ($195)). The snickerdoodle one only comes with pins in the "up" orientation and doesn't support any baseboards. But you can still plug the jumpers into the pins and wire up things on a breadboard.
numato Mimas A7 Xilinx Artix 7 52K $149 No 2Gb DDR3 RAM. Gigabit Ethernet. HDMI IN/OUT. 100MHz LVDS oscillator. 80 IOs. 7-segment display, LEDs, buttons. (Found in this Reddit thread.)
Ultra96 Xilinx Zynq UltraScale+ ZU3EG 154K $249 Yes Has one of the latest Xilinx SoCs. 2 GB (512M x32) LPDDR4 Memory. Wi-Fi / Bluetooth. Mini DisplayPort. 1x USB 3.0 type Micro-B, 2x USB 3.0 Type A. Audio I/O. Four user-controllable LEDs. No buttons and limited LEDs, but easy to wire up your own on a breadboard
Nexys A7-100T Xilinx Artix 7 15,850 $265 No . 128MiB DDR2 RAM. Ethernet port, PWM audio output, accelerometer, PDM microphone, microphone, etc. 16 switches, 16 LEDs. 7 segment displays. USB HID Host for mice, keyboards and memory sticks.
Zybo Z7-10 Xilinx Zynq 7010 17,600 $199 Yes Xilinx Zynq 7000 SoC (ARM Cortex-A9, 7-series FPGA.) 1 GB DDR3 RAM. A few switches, push buttons, and LEDs. USB and Ethernet. Audio in/out ports. HDMI source + sink with CEC. 8 Total Processor I/O, 40 Total FPGA I/O. Also a faster version for $299 (Zybo Z7-20).
Arty A7 Xilinx Artix 7 15K $119 No 256MB DDR3L. 10/100 Mbps Ethernet. A few switches, buttons, LEDs.
DE10-Standard (specs) Altera Cyclone V 110K $350 Yes Dual-core Cortex-A9 processor. Lots of buttons, LEDs, and other peripherals.
DE10-Nano Altera Cyclone V 110K $130 Yes Same as DE10-Standard, but not as many peripherals, buttons, LEDs, etc.


icoBoard ($100). (Buy it here.)
The icoBoard plugs into a Raspberry Pi, so it's similar to having a SoC. The iCE40-HX8K chip comes with 7,680 LUTs (logic elements.) This means that after you learn the basics and create some simple circuits, you'll also have enough logic elements to run the VexRiscv soft-core CPU (the lightweight Murax SoC.)
The icoBoard also supports a huge range of pluggable pmod accessories:
You can pick whatever peripherals you're interested in, and buy some more in the future.
Every FPGA vendor keeps their bitstream format secret. (Here's a Hacker News discussion about it.) The iCE40-HX8K bitstream has been fully reverse engineered by Project IceStorm, and there is an open-source set of tools that can compile Verilog to iCE40 bitstream.
This means that you have the freedom to do some crazy experiments, like:
You don't really have the same freedom to explore these things with Xilinx or Altera FPGAs. (Especially asynchronous circuits.)


Second Place:

iCE40-HX8K Breakout Board ($49)

Third Place:

numato Mimas A7 ($149).
An excellent development board with a Xilinx Artix 7 FPGA, so you can play with a bigger / faster FPGA and run a full RISC-V soft-core with all the options enabled, and a much higher clock speed. (The iCE40 FPGAs are a bit slow and small.)
Note: I've changed my mind several times as I learned new things. Here's some of my previous thoughts.

What did I buy?

I ordered a iCE40-HX8K Breakout Board to try out the IceStorm open source tooling. (I would have ordered an icoBoard if I had found it earlier.) I also bought a numato Mimas A7 so that I could experiment with the Artix 7 FPGA and Xilinx software (Vivado Design Suite.)


What can I do with an FPGA? / How many LUTs do I need?

Cryptocurrency Mining History : Journey to PoC

Cryptocurrency just like any other technological development has given birth to many side industries and trends like ICO, white paper writing, and mining etc… just the cryptocurrency itself rises, falls and changes to adapt real life conditions, so does its side industries and trends. Today we are going to be focusing on mining. How it has risen, fell and adapted through the journey of cryptocurrency till date.
Without going into details crypto mining is the process by which new blocks are validated and added to the blockchain. It first took to main stream in January 2009 when the mysterious Satoshi Nakamoto launched the bitcoin white paper within which he/she/they proposed the first mining consensus mechanism called proof of work (Pow).
The PoW consensus mechanism required that one should spend a certain amount of computational power to solve a cryptographic problem (nounce) in other to have the have the right to pack/verify the next block on the blockchain. In this mechanism, the more computational power one possesses the more rights they have over the packing of the next block. The quest for faster hardware has seen significant changes in the types of hard ware dominating the PoW mining community.
Back in 2009 when bitcoin first started a normal pc and its processing power worked just fine. In fact a pc with an i7 Intel processor could mine up to 50btc per day but back then it almost nothing since btc was only some few cents. When the difficulty of the network became significantly high, simple computer processing units could not match the competitiveness and so miners settled for something more powerful, the high end graphic processors (GPU). This is when the era of rigs began It was in 2010. People would combine GPUs together in mining rigs on a mother board usually in order of 6 per rig some miners operated farms containing many of these rigs. Of course with greater power came greater network difficulty and so the search for faster hard ware let to implementation of Field Programmable Gate Arrays (FPGA) in June 2012. A further search for faster, less consuming and cheaper hard ware let us to where we are today. In the year 2013, Application Specific Integrated Circuits (ASIC) miners were introduced. One ASIC miner processes 1500H/s which is 100 times processing power of CPU and GPU. But all this speed and efficiency achievements brought about another problem one which touches the core of cryptocurrency itself. The idea of decentralization was gradually fading away as wealthy and big companies are the once who could afford and build the miners therefore centralizing mining around the rich, there was a called for ASIC resistant consensus mechanism.
A movement for ASIC resistant PoW algorithms began the idea is to make ASIC mining impossible or at least make it such that using ASIC doesn’t give a miner any additional advantage as to using CPU . In 2013 the MONERO the famous privacy coin proposed CryptoNight an ASIC resistant PoW consensus at least that is how they intended it to be. But things have proven much more difficult in practice than they had anticipated as ASIC producers keep matching up to every barrier put in place the PoW designers at a rate faster than it takes to build these barriers. MONERO for example has to fork every now and then in other to keep the CryptoNight ASIC resistant a trick which is still not working as reported by their CEO “We [also] saw that this was very unsustainable. … It takes a lot to keep [hard forking] again and again for one. For two, it may decentralize mining but it centralizes in another area. It centralizes on the developers because now there’s a lot of trust in developers to keep hard forking.” Another PoW ASIC resistance algorithm is the RamdonX and there are many others but could quickly imagine that the barriers to ASIC mining in these ASIC resistance algorithm would eventually be broken by the ASIC miners and so a total shift from PoW mining to other consensus mechanisms which are ASIC resistance from core were proposed some of which are in use today.
Entered the Proof of Stake (PoS) consensus mechanism. PoS was first introduced in 2013 by the PeerCoin team. Here, a validator’s right to mine is proportionate to his/heit economic value in the network simple put the more amounts of coins you have the more mining rights you get. Apart from PeerCoin, NEO and LISK also use POS and soon to follow is EThereum. There are different variations to PoS including but not limited to delegated proof of stake DPoS, masternode proof of stake MPoS each of which seek to improve on something in the POS. This is a very good ASIC resistance consensus mechanism but it still doesn’t solves the centralization problem as the rich always have the power to more coins and have more mining rights plus it is also expensive to start. And then we have gotten many other proposals to combat this among which are Proof of Weight (PoW) and Proof of Capacity (PoC). We take more interest in PoC it is the latest and gives the best solution to all our mining challenges consensus as of now.
Proof of Capacity was first was described 2013 in the Proofs of Space paper by Dziembowski, Faust, Kolmogorov and Pietrzak and it is now being used in Burst. The main factor that separates all the mining mechanisms is the resource used. These resources which miners spend in other to have mining rights is a measure of ensuring that one has expense a none-trivial amount of effort in making a statement. The resource being spent in PoC is disk space. This is less expensive since many people already have some unused space lying around and space is a cheap resource in the field of tech. it has no discrimination over topography… it really solves lots of centralized problems present in all most other consensus. If the future is now then one could say the future of crypto mining is PoC.

Crypto and the Latency Arms Race: Crypto Exchanges and the HFT Crowd

Crypto and the Latency Arms Race: Crypto Exchanges and the HFT Crowd

News by Coindesk: Max Boonen
Carrying on from an earlier post about the evolution of high frequency trading (HFT), how it can harm markets and how crypto exchanges are responding, here we focus on the potential longer-term impact on the crypto ecosystem.
First, though, we need to focus on the state of HFT in a broader context.

Conventional markets are adopting anti-latency arbitrage mechanisms

In conventional markets, latency arbitrage has increased toxicity on lit venues and pushed trading volumes over-the-counter or into dark pools. In Europe, dark liquidity has increased in spite of efforts by regulators to clamp down on it. In some markets, regulation has actually contributed to this. Per the SEC:
“Using the Nasdaq market as a proxy, [Regulation] NMS did not seem to succeed in its mission to increase the display of limit orders in the marketplace. We have seen an increase in dark liquidity, smaller trade sizes, similar trading volumes, and a larger number of “small” venues.”
Why is non-lit execution remaining or becoming more successful in spite of its lower transparency? In its 2014 paper, BlackRock came out in favour of dark pools in the context of best execution requirements. It also lamented message congestion and cautioned against increasing tick sizes, features that advantage latency arbitrageurs. (This echoes the comment to CoinDesk of David Weisberger, CEO of Coinroutes, who explained that the tick sizes typical of the crypto market are small and therefore do not put slower traders at much of a disadvantage.)
Major venues now recognize that the speed race threatens their business model in some markets, as it pushes those “slow” market makers with risk-absorbing capacity to provide liquidity to the likes of BlackRock off-exchange. Eurex has responded by implementing anti-latency arbitrage (ALA) mechanisms in options:
“Right now, a lot of liquidity providers need to invest more into technology in order to protect themselves against other, very fast liquidity providers, than they can invest in their pricing for the end client. The end result of this is a certain imbalance, where we have a few very sophisticated liquidity providers that are very active in the order book and then a lot of liquidity providers that have the ability to provide prices to end clients, but are tending to do so more away from the order book”, commented Jonas Ullmann, Eurex’s head of market functionality. Such views are increasingly supported by academic research.
XTX identifies two categories of ALA mechanisms: policy-based and technology-based. Policy-based ALA refers to a venue simply deciding that latency arbitrageurs are not allowed to trade on it. Alternative venues to exchanges (going under various acronyms such as ECN, ATS or MTF) can allow traders to either take or make, but not engage in both activities. Others can purposefully select — and advertise — their mix of market participants, or allow users to trade in separate “rooms” where undesired firms are excluded. The rise of “alternative microstructures” is mostly evidenced in crypto by the surge in electronic OTC trading, where traders can receive better prices than on exchange.
Technology-based ALA encompasses delays, random or deterministic, added to an exchange’s matching engine to reduce the viability of latency arbitrage strategies. The classic example is a speed bump where new orders are delayed by a few milliseconds, but the cancellation of existing orders is not. This lets market makers place fresh quotes at the new prevailing market price without being run over by latency arbitrageurs.
As a practical example, the London Metal Exchange recently announced an eight-millisecond speed bump on some contracts that are prime candidates for latency arbitrageurs due to their similarity to products trading on the much bigger CME in Chicago.
Why 8 milliseconds? First, microwave transmission between Chicago and the US East Coast is 3 milliseconds faster than fibre optic lines. From there, the $250,000 a month Hibernia Express transatlantic cable helps you get to London another 4 milliseconds faster than cheaper alternatives. Add a millisecond for internal latencies such as not using FPGAs and 8 milliseconds is the difference for a liquidity provider between investing tens of millions in speed technology or being priced out of the market by latency arbitrage.
With this in mind, let’s consider what the future holds for crypto.

Crypto exchanges must not forget their retail roots

We learn from conventional markets that liquidity benefits from a diverse base of market makers with risk-absorption capacity.
Some have claimed that the spread compression witnessed in the bitcoin market since 2017 is due to electronification. Instead, I posit that it is greater risk-absorbing capacity and capital allocation that has improved the liquidity of the bitcoin market, not an increase in speed, as in fact being a fast exchange with colocation such as Gemini has not supported higher volumes. Old-timers will remember Coinsetter, a company that, per the Bitcoin Wiki , “was created in 2012, and operates a bitcoin exchange and ECN. Coinsetter’s CSX trading technology enables millisecond trade execution times and offers one of the fastest API data streams in the industry.” The Wiki page should use the past tense as Coinsetter failed to gain traction, was acquired in 2016 and subsequently closed.
Exchanges that invest in scalability and user experience will thrive (BitMEX comes to mind). Crypto exchanges that favour the fastest traders (by reducing jitter, etc.) will find that winner-takes-all latency strategies do not improve liquidity. Furthermore, they risk antagonising the majority of their users, who are naturally suspicious of platforms that sell preferential treatment.
It is baffling that the head of Russia for Huobi vaunted to CoinDesk that: “The option [of co-location] allows [selected clients] to make trades 70 to 100 times faster than other users”. The article notes that Huobi doesn’t charge — but of course, not everyone can sign up.
Contrast this with one of the most successful exchanges today: Binance. It actively discourages some HFT strategies by tracking metrics such as order-to-trade ratios and temporarily blocking users that breach certain limits. Market experts know that Binance remains extremely relevant to price discovery, irrespective of its focus on a less professional user base.
Other exchanges, take heed.
Coinbase closed its entire Chicago office where 30 engineers had worked on a faster matching engine, an exercise that is rumoured to have cost $50mm. After much internal debate, I bet that the company finally realised that it wouldn’t recoup its investment and that its value derived from having onboarded 20 million users, not from upgrading systems that are already fast and reliable by the standards of crypto.
It is also unsurprising that Kraken’s Steve Hunt, a veteran of low-latency torchbearer Jump Trading, commented to CoinDesk that: “We want all customers regardless of size or scale to have equal access to our marketplace”. Experience speaks.
In a recent article on CoinDesk , Matt Trudeau of ErisX points to the lower reliability of cloud-based services compared to dedicated, co-located and cross-connected gateways. That much is true. Web-based technology puts the emphasis on serving the greatest number of users concurrently, not on serving a subset of users deterministically and at the lowest latency possible. That is the point. Crypto might be the only asset class that is accessible directly to end users with a low number of intermediaries, precisely because of the crypto ethos and how the industry evolved. It is cheaper to buy $500 of bitcoin than it is to buy $500 of Microsoft shares.
Trudeau further remarks that official, paid-for co-location is better than what he pejoratively calls “unsanctioned colocation,” the fact that crypto traders can place their servers in the same cloud providers as the exchanges. The fairness argument is dubious: anyone with $50 can set up an Amazon AWS account and run next to the major crypto exchanges, whereas cheap co-location starts at $1,000 a month in the real world. No wonder “speed technology revenues” are estimated at $1 billion for the major U.S. equity exchanges.
For a crypto exchange, to reside in a financial, non-cloud data centre with state-of-the-art network latencies might ironically impair the likelihood of success. The risk is that such an exchange becomes dominated on the taker side by the handful of players that already own or pay for the fastest communication routes between major financial data centres such as Equinix and the CME in Chicago, where bitcoin futures are traded. This might reduce liquidity on the exchange because a significant proportion of the crypto market’s risk-absorption capacity is coming from crypto-centric funds that do not have the scale to operate low-latency strategies, but might make up the bulk of the liquidity on, say, Binance. Such mom-and-pop liquidity providers might therefore shun an exchange that caters to larger players as a priority.

Exchanges risk losing market share to OTC liquidity providers

While voice trading in crypto has run its course, a major contribution to the market’s increase in liquidity circa 2017–2018 was the risk appetite of the original OTC voice desks such as Cumberland Mining and Circle.
Automation really shines in bringing together risk-absorbing capacity tailored to each client (which is impossible on anonymous exchanges) with seamless electronic execution. In contrast, latency-sensitive venues can see liquidity evaporate in periods of stress, as happened to a well-known and otherwise successful exchange on 26 June which saw its bitcoin order book become $1,000 wide for an extended period of time as liquidity providers turned their systems off. The problem is compounded by the general unavailability of credit on cash exchanges, an issue that the OTC market’s settlement model avoids.
As the crypto market matures, the business model of today’s major cash exchanges will come under pressure. In the past decade, the FX market has shown that retail traders benefit from better liquidity when they trade through different channels than institutional speculators. Systematic internalizers demonstrate the same in equities. This fact of life will apply to crypto. Exchanges have to pick a side: either cater to retail (or retail-driven intermediaries) or court HFTs.
Now that an aggregator like Tagomi runs transaction cost analysis for their clients, it will become plainly obvious to investors with medium-term and long-term horizons (i.e. anyone not looking at the next 2 seconds) that their price impact on exchange is worse than against electronic OTC liquidity providers.
Today, exchange fee structures are awkward because they must charge small users a lot to make up for crypto’s exceptionally high compliance and onboarding costs. Onboarding a single, small value user simply does not make sense unless fees are quite elevated. Exchanges end up over-charging large volume traders such as B2C2’s clients, another incentive to switch to OTC execution.
In the alternative, what if crypto exchanges focus on HFT traders? In my opinion, the CME is a much better venue for institutional takers as fees are much lower and conventional trading firms will already be connected to it. My hypothesis is that most exchanges will not be able to compete with the CME for fast traders (after all, the CBOE itself gave up), and must cater to their retail user base instead.
In a future post, we will explore other microstructures beyond all-to-all exchanges and bilateral OTC trading.

FPGA mining efficiency (hashing speed/power consumption) is very efficient, compared to GPU mining and drastically outperforms CPU mining. However, ASIC is still faster and more efficient than FPGA. Main Difference Between FPGA and ASIC Mining. During the last years, the bitcoin mining ecosystem has been experiencing important changes. At the beginning, it was possible to mine bitcoin with a CPU processor, but later, it was possible to do it with GPUs. What is Bitcoin Mining Hardware. The right bitcoin mining hardware is a necessity if you want to earn during bitcoin mining. Before, miners used a central processing unit (CPU) to mine, but it wasn’t fast enough.. So, miners moved on to using graphical processing unit (GPU) in computer graphics cards as they have data 50 to 100 times faster and consume less power per unit of work. Good news! Bitcoin ended its bear run in Q1 2019 and staggered the market with its significant comeback with a bull run in the closing of Q2. The price soars above $13,000 — rising 300% since Like a lot of my fellow miners out there, I came from a GPU mining world. As a GPU miner myself, I was both curious and concerned about the growing FPGA mining ecosystem. After weeks of research and testing, we compiled the first version of the to share what we've learned so far. This is now the fourth revision of
