5 Best USB Bitcoin Miners 2020 – Reviews & Buying Guide
Notice to Upcoming Bitcoin Miners: USB hubs
I did four hours of research after I wasn't able to connect 20 USB ASICminers to two $7 USB hubs from eBay. Be advised: you need to get expensive hubs that advertise their amperage as half the number of ASICs you want to use; ASICminers use a LOT of power. The cheapest I found were Amazon brand (yes brand) at $20 for seven ports, plus tax. The price of functional hubs has gone up with increased demand brought on by the ASIC market.

I don’t know if it’s just me but I decided I wanted to mine some bitcoin using my gpu at first I kept getting virus alert messages that I gave access btw I downloaded nice hash directly from the GitHub page they redirected me to . So then later I noticed the symptoms of the virus begin to show up. The computer started running very slowly also all my norton firewalls were off somehow I did not switch them off every time I went to switch it back on norton crashed. Then comping to the internet I don’t know if it’s Cisco Webex but it never did this before I was using my phone and it kept loading and never joined . At this point I decided to disconnect my internet from my pc. It then connected . I think bandwidth was reduced but can’t be sure it could be webex’s fault .anyone confirm if this.I booted into safe mode after and after that I could not login using my password I don’t think that is a symptom of the virus but can someone confirm this. Update :- my pc now wasn’t booting up non of the ports were working my keyboard or mouse were not working ik cause they didn’t light up meaning no power . So I did a cmos reset didn’t work so my motherboard has the option to Re flash the bios it’s the x570 meg motherboard so I reflagged my bios and it booted up . Btw this never happened I build my pc myself tested each and every part only after I downloaded this garbage miner I started facing problems. When u think antivirus are lying I don’t think so y other miners work perfectly fine with the antivirus only this piece of shit software doesn’t . It somehow managed to go to my bios how the f did they do that idk but I swear u literally want trouble if u download this Edit 3:- ended up deleting windows and downloading it back from a usb stick
I earned about 4000% more btc with my android tablet than with a $250 ASIC mini rig setup using GekkoScience Newpac USB miners!
Requirements: 1.) Android Device with access to Google Play Store. *I haven't tried yet but you may be able to use tis on Android TV devces as well by sideloading. If anyone has success before I try, let me know! -Note, I did this with a Samsung Galaxy Tab S6 so its a newer more powerful device. If your android is older, your profts will most likely be less than what I earned but to give a projected range I also tested on my Raspberry Pi 4 running a custom LineageOS rom that doesn't allow the OS to make full use of the Pi's specs and I still got 500 h/s on that with Cloud boost, so about 60% of what my Tab 6 with MUCH Higher Specs does. **Hey guys. Before I get started i just wanted to be clear about one thing. Yes I have seen those scammy posts sharing "miracle" boosts and fixes. I have a hard time believing stuff online anymore. But this is honestly real. Ill attach photos and explain the whole story and process below. Thanks for taking the time to read and feel free to share any thoughts, concerns, tips, etc* So last week I finally got started with my first mini rig type mining build. I started getting into crypto about a year ago and it has taken me a long time to even grasp half of the projects out there but its been fun thus far! Anyways my rig was 2 GekkoScience Newpac USB miners, a Moonlander USB miner to pair with an FPGA i already had mining, a 10 port 60W 3.0 USB hub and 2 usb fans. The Newpacs actually are hashing at a combined 280 g/s which is actually better than their reported max hash rate when overclocked. Pleasant surpise and they are simple!! I just wanted to get a moonlander because my fpga already mines on Odocrypt for DGB and I just wanted to experience Scrypt mining and help build the DGB project. The Newpacs are mining BTC though. After I got everything up and running i checked my payout daily average after 1 week. I averaged .01 a day TOTAL between all three miners with them all perforing ABOVE SPEC!!! I had done research so i knew I wouldnt earn much. More than anything i just wanted to learn. But still. I was kinda surprised in a negative way. Yesterday I actually earned less than .01 Frustrated I went back to scouring the web for new ideas. About a year ago, when II was starting, I saw an app on my iphone called CryptoBrowser that claimed to mine btc on your phone without actually using phone resources using a method of cloud mining. I tried it for a week and quit because I earned like .03 after a ton of use and seemed scammy. Plus my iphone actually would get very hot when doing this so I quit using it as it seemed like a possible scam with all the cryptonight browser mining hacks and malware out there. Anyways I was on my Galaxy Tab S6 and saw that CryptoBrowser released a "PRO" edition for 3.99 on Google Play. I bought it for Sh*ts and giggles and booted it up. It came with what they called "Cloud Boost" Essentially this is a button you press and it multiplys the estimated hashrate that it gives you device by the number shown on the boost button. (With the purchase of PRO you get one free x10 boost. You can purchase additional boosts to use with other android devices but those are actually pretty pricy. Another x10 boost was like $25 if i remember correctly). I played with it for about an hour to see if it actually worked like it said it would this time. To my surprise, as i was browsing, my device didnt increase in temperature AT ALL!!!!! I checked my tast manager to confirm and it was indeed true, my memory and usage barely went up. it was giving me an estimated range of 80-105 on the hashrate. Once i pushed the x10 boost button, that went to 800-1150 h/s. I switched my screen to not go to sleep, plugged it to the charge and let it run on the browser page, hashing. When you push the boost button, it runs for 3 hours at the boosted speeds. After that it goes back to normal but if you press the button again, it boosts everything again. There is no limit to how many times you use it. After checking what I earned after 24 hours, I HAD MADE .40 in BTC!!!!! I JUST EARNED OVER 4000% MORE THAN MY $280 MINING RIG EARNED ME!!!! I was blown away. Maybe this was a fluke? I did it again next day. Every 3 hours or so I would push the button again but thats all. Sure enough, .35 that day. Also, it realy BTC. I requested a payout and although it took like 12 hours for them to send me an email stating they had just sent it, I actually did recieve the state amount of BTC within 24 hours in my personal wallet. The fees to send are SUPER LOW!. Like .01 Below I will list the steps I took, along with an explanation of thier "Mining" process on Androids. Reminder, this ONLY WORKS ON ANDROIDS. Also DO NOT use cryptobrowser on a physcal laptop or desktop. I ran it on an old laptop for three days last year and it fried it. It does actually use your hardware on those platforms to mine and it is not efficnet at all as I suspect they prob steal over half of your power for themselves using the REAL RandomX protocol via browser mining which is EXTREMELY INEFFICIENT DONT TRY IT!! -----How To Do This Yourself: Cryptotab Browser states the program works on Android devices by estimating what it thinks the hashrate would be for your device specs and siimulates what you would mine in a remote server however you still earn that estimated coin amount. It is not a SHA-256 process or coin that they say is mining, rather it is XMR and they swap that and pay it out to you in BTC Bitcoin. However I know damn well my Tab S6 doesnt hash 80-105 h/s on RandomX because I have done it with a moodified XMRig module i ported to Android. I got 5 h/s a sec if I was getting any hashes at all. But thats besides the point as I still was making money. Now, when you press that cloud boost button it immediately boosts that hash rate it estimates by the number on the cloud boost. As stated above, you can purchase more boosts and gift them or use them on extra android devices that you may have. Again, they are pricey so I'm not doing that plus it would just mean that I have another device that I have to leave on and open. The boosts come in x2, x4, x6, x8 and x10 variants. Again, they have unlimited uses. Here is the link to grab yourself CryptoBrowser Pro from CryptoTab. This IS A REFERRAL LINK! This is where I benefit from doing tis tutorial. Like i said, I want to be transparent as this is not a scam but I'm also not doing this out of the love of my heart. Their referral system works in that people that use the donwload the app using your link are your stage 1 referrals. Anytime they are mining, you earn a 15% bonus. So say they mine $.30 one day. You would get paid out an additional $.045 in your own balance (it does not come out of the referred user balance fyi so no worries). Then lets say that referred miner also gets their own referrals. I would get a 10% bonus on whatever THOSE people mine. This goes on and on for like 8 tiers. Each tier the bonus percntage essential halves. So again, I stand to benefit from this but it also is stupid to not make this visible as its WAY CHEAPER, EASIER AND MORE PROFITABLE TO GET BTC USING THIS METHOD THAN IT IS USING ASICS!! THIS EARNS ALMOST AS MUCH BTC AS AN ANTMINER S7 DOES RUNNING 24/7 ONLY WITHOUT THE HUGE ELLECTRICTY BILL AND COSTS!!!!) Thats it. Again, if you have concerns, let me know or if you have suggestions, other tips, etc... mention those as well!!! https://cryptotabbrowser.com/8557319 Links to Picture Proof http://imgur.com/gallery/P13bEsB
I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O
Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.** A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it: - Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have. - My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's. - I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose... - I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS. ______________________ Q2) What is your maximum budget before rebates/shipping/taxes?** * A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK). ______________________ Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.** A3) IMMEDIATELY! :) ______________________ Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)** A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\*
______________________ Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?** A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference? ______________________ Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.** A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean). ______________________ Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?** A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science). ______________________ Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)** A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well. - This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\* - I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\* - Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\* - Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts. - Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?) ______________________ Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?** A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports. ______________________ Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?** A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though. ______________________ ______________________ ______________________ **Extra info or particulars:*\* AND NOW TO THE FUN-STUFF... Here's a list of everything (PARTS PARTS PARTS) I have on-hand and ready to deploy into the wild &/or negotiate a trade/barter with: CASES - Corsair Carbide Series Air 540 Arctic White (Model# Crypto-Currency-9011048-WW) - (Probably my top pick for this build). Cooler Master HAF XB EVO (This is probably my top 1st or 2nd pick for this build, the thing is a monster!).

At which time I'd be obliged to send an itemized list or see if I have what they're/you're specifically looking for.\* ______________________ THERMAL APPLICATIONS/FANS - JUST FANS - BeQuiet - Pure Wings 2 (80mm) Pure Wings 2 (120mm) Pure Wings 2 (140mm) Silent Wings 3 PWM (120mm) NOCTUA - PoopBrown - NF-A20 PWM (200mm) Specifically for the BIG "CoolerMaster HAF XB EVO" Case GREY - NF-P12 Redux - 1700RPM (120mm) PWM Corsair - Air Series AF120LED (120mm) CPU COOLING SYSTEMS - NOCTUA - NT-HH 1.4ml Thermal Compound NH-D15 6 Heatpipe system (this thing is the tits) EVGA (Extremely crappy coding in the software here, I'm like 99.99% these will be problematic if I were to try and use in any OS outside of Windows, because they barely ever work in the intended Windows as it is). CLC 240 (240mm Water-cooled system CRYORIG - Cryorig C7 Cu (Low-Profile Copper Edition*) A few other oversized CPU cooling systems I forget off the top of my head but a CPU cooler is a CPU cooler after comparing to the previous 3 models I mentioned. I almost exclusively am using these amazing "Innovation Cooling Graphite Thermal Pads" as an alternative to thermal paste for my CPU's. They're not cheap but they literally last forever. NZXT - Sentry Mesh Fan Controller ______________________ POWER SUPPLIES (PSU's) - BeQuiet 550W Straight Power 11 (GOLD) EVGA - 750P2 (750W, Platinum) 850P2 (850W, Platinum) 750T2 (750W, TITANIUM - yeah baby, yeah) ROSEWILL - Quark 750W Platinum Quark 650W Platinum SEASONIC - Focus 750W Platinum ______________________ STORAGE - HGST Ultrastar 3TB - 64mb Cache - 7200RPM Sata III (3.5) 4X Samsung 860 EVO 500GB SSD's 2X Team Group L5 LITE 3D 2.5" SSD's 480GB 2X WD 10TB Essential EXT (I'm cool with shucking) + 6X various other external HDD's (from 4-8TB) - (Seagate, WD & G-Drives) ______________________ Other accessories worth mentioning - PCI-E to 4X USB hub-adapter (I have a dozen or so of these - might not be sufficient enough &/or needed but again, 'worth mentioning' in case I somehow ever run out of SATA & USB ports and have extra external USB HDD's. Although, I'm sure there would be better suited components if I get to that point that probably won't cost all that much). ______________________ ______________________ ______________________ Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc... Naturally, I have GPU's. Specifically; At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one. I also have some GTX 1080 TI's but those are already spoken for, sorry. It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP. In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well... Rig 1 = EPIC NAS SYSTEM Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL Oh, I almost forgot... The current routers I'm using are... 1X Netgear Nighthawk 6900P (Modem + Router) 1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one) 1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices. ---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :) Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years. TIA for assisting in any way possible. Gotta love the internets! THE END. :) EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here... I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent. One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind. I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids. Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).* I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows: EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else... (Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT). Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner: *** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\* Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. = 'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat. I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale. Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/. THE END (Round#2)
Hey guys, I am currently trying to get into the bitcoin mining with the hopes of having a steady output of some satoshis. I am quite aware of the current state of the mining business and have run the calculations. So: I am not looking for a quit break even, I just want a steady flow of like 2000 satoshis a day. To achieve that I have purchased two GekkoScience 2-Pac and I intend to get more over time. What is missing is the USB hub. I am quite unsure what would be the best pick. What I intend to have is a hub that enables me to have like 5 of these asics pointing upwards and still having at least one, better two, ports free to also run USB fans. And all ports should deliver maximum power (14W) so that I can run the miners on full speed. Does anyone have any suggestion for such a hub? Short summary for the hub I want:
5 ports for miners
1 or 2 ports for fans
at least 14W output for each port
ports poiting upwards
ports having enough physical space between them so that the all miners will fit
I somehow guess that there is not the perfect hub I want. But I hope that at least with the help of you guys I get to the next best fit ;) Thanks in advance!
I have already ordered a Raspberry Pi 3 and I know I need to install NOOBS onto it. I've watched a few videos on making a Bitcoin mine so I know/have everything I'm going to need. However, I'm having trouble finding USB bitcoin miner. I've found this one on Amazon for $70, but I'm not sure it's the best option and I'm hoping one of you could help me out. Thanks in advance.
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: https://www.reddit.com/FPGA/comments/1xsk6w/cyclone_v_gx_starter_kit_vs_de1soc_board/ (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:
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.
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.
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
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).
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:
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.)
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?
VexRiscv is "A FPGA friendly 32 bit RISC-V CPU implementation." This is a RISC-V implementation written in SpinalHDL. VexRiscv has a lot of plugin and configuration options. The Murax SoC is a very light SoC that can run on an iCE40-HX8k (but probably not the 1k FPGA that only has 1,280 LUTs). The Briey SoC only runs on Xilinx or Altera FPGAs.
part 3: down the NodeRed rabbit hole - resurrection (long)
so, now that i've got about 4 weeks of NR experience under my belt, i thought i would do a follow up and show a few new flows. plus, i've picked up a few new hardware add-ons. namely a Harmony Hub and a coupla Sonoff/Tasmota S31. one of the new things i did was setup some global.variables i can use in any flow. https://imgur.com/YFJEwRd 1] is pretty obvious, does my bayesian sensors think i'm home/not_home, and then save it to a global.variable. 2] reads the MQTT for my S31 power monitor on my dumb TV. if it's > 100, then the TV is ON, <= 99, then TV is OFF (or in the process of turning off). then set a global.variable for on/off. https://imgur.com/mcuS1Vk 3] i changed the day/night temperatures to global.variables. 4] this one gets the current volume level of my Sonos and then stores that to a global.variable. (get to why further below) 5] this one i talked about in another post here: https://www.reddit.com/homeassistant/comments/abvqup/device_tracker_with_unifi2mqtt/ okay, so now that i know if my dumb TV is on/off, then i can add it into my "away" (and "bedtime") flow. that gray one on the bottom right is using the HarmonyHub control node to fire the power toggle. (which i'll get to further below) plus it'll stop my Sonos, if it's playing. https://imgur.com/nerbMv3 also you may notice the "alexa TTS" one, that's a subflow, which is a bit of reusable flow, you can put anywhere you want it. this one picks a random number between 1 and 10, then alexa TTS plays the corresponding message. https://imgur.com/bLtBlaD this was also my attempt to get alexa to say "aaaf-firmative" like newt in aliens. https://imgur.com/cUnG1IE doesn't really work, but i'm determined to make this happen. gonna have to figure out the proper phonetics of it. then i'm totally gonna get her to do a stutter like max headroom on one of the other responses. but, my ultimate goal is to get her to do "twiki" from buck rogers. beaty beaty anyways, i've also added that subflow to all my switch on/offs. along with an MQTT log. https://imgur.com/SnpAnW8 now for some of the new stuff... here's a sleep timer. if i'm listening to music in bed, i can activate this with "alexa turn on sleep" and what it does, is it takes the current volume level of my Sonos, stored in a global.var, stores it in a flow.var, then subtracts 1 every minute, until it reaches zero. if the volume is at 30, then it'll be 30 mins until zero. https://imgur.com/7QmbY2S once it reaches zero, it stops the music, sets the volume back to the original state (ie: 30) and then turns itself off. there's an issue when you use something like a Harmony Hub to turn on/off dumb devices via input_bool, or switches, or lights, etc.: that once you turn it on via NR, HA, HHub, Alexa, etc., then HA thinks it's on. if you then turn it off via the device remote, HA won't let you turn it on again, because HA thinks its already on. so, i had to use a script and a "dummy" input_boolean. by dummy i mean, that i do not care, and will not EVER care, what it's state is. on. off. whatever. won't need it. it just needs to be there for the script to work.
input_boolean: mac_x: game_x: candles_x: tv_x:
hide them from emu_hue, cause Alexa doesn't need to see them either.
so instead of key'ing off the input_booleans, i key off the script call. "alexa, turn on candles" calls the script, which toggles the i_b but i only care about the state change of the script. then NR does it's thing. https://imgur.com/Hky9fWd notice tho, that it's a little smart. if the tv is already on, via that global.var, then it just switches inputs, otherwise it turns it on, waits 7 seconds, then switches inputs. okay, here's something REALLY advanced. i have a second pi running cgminer with a USB hub and some USB stick ASIC bitcoin miners. and every once and a while, they stop working and need to be reset. and you can't just restart, you gotta kill the power to the hubs to get them to reset. and then restart cgminer. enter NR cgminer node and the cgminer API. https://imgur.com/POSkjrp so every 5 mins, hit the cgminer API, it returns stats in json, dump those to mqtt. use the function node to pull out the array nested values we need to look at. look for a zero value in any of them. if the input_boolean "auto-reset-miner" is on, then lets reset. stop cgminer, wait, turn off the USB hub, wait, turn on hub, wait, start cgminer, send an alert to mqtt and SMS me. now the real magic is the red exec "start cgminer" node. because we stopped cgminer, we have to start it again, on a whole other computer than NR is on. it basically does a SSH into the miner pi and starts up cgminer. this was difficult to accomplish inside a docker of NR. i had to move some ssh keys around and then reference them with full paths. then i had to do an ssh-copy-id so it didn't require a password.
Because cold wallets, such as those stored offline in a text file as I keep recommending in my standard advice below: All you need is a text file to put your wallets in, like this example from https://walletgenerator.net/?currency=Dogecoin 1,"D7WBUpdgLRtG6WyPsqjhaKiJR65X8ZGnkZ","6KieLMW1poAzNVnmLuQZqA262gxEQ51eLGdDK8e2GL2B4LHCKKb"2,"DM8LT16d49zHr8ByXbUwZb9UBXDGMaZRdc","6Ktgxdv6vN9v2bDHwcJBBb3oMRAgXJumESzBnxaXUSGFZoq6pWQ"3,"D5UCa51AfxjtVHQ46oYXe2YfkctTeLXPhx","6L2WSPWadRYCwt2L1CxH6zC7PoTYY3KyjxdiUoCqi5eyq6hQKvj" Use https://coinb.in/#settings to move coins. Download both sites and run them offline. Use https://bitinfocharts.com/dogecoin/ to check balances and transactions. See http://www.mocacinno.com/blog/create-sign-broadcast-transactions-using-coinb/ for coinb.in tutorial. And read the ELI5s (and my history) for more info. Are without doubt THE SAFEST way to store your coins. Plus, they consume no resources. No bandwidth, no network stress for every node we have, no storage of 20Gb+ blockchains, no weeks of waiting for things to sync, no tearing your hair out and posting desperate pleas for help, and most importantly, no coins irretrievably lost because you or your client screwed up.
Wallets, ALL WALLETS are nothing but numbers. Very large numbers, but fundamentally no different from “7”, “42”, “911” or a phone number. They cannot be created nor destroyed, and you either know them or you don’t. Anyone who knows a key can use it to spend any coins it controls. Anyone who doesn’t know it, can’t. Don’t be the guy who doesn’t know his own keys. Keep them safe. Make copies. Keep those safe. Don’t let your friends, kid brother or random burglar find them, but don’t lose them either. The only other thing you need for a fully functional wallet is a way to spend coins. Coinb.in is such a way. There are others, such as DogeCoinMultiSig.org which tomcarbon built. Oh, and you can and should download it and run it locally.
The default entry point for coinb.in is https://coinb.in/#settings because this settings page is very well hidden. Its in the tiny gear wheel on the Broadcast page. Looking across the top of the page, you can see
We’re only going to use three of these. New, Sign, Broadcast. Now, keep in mind that coinb.in is an old Bitcoin tool which tomcarbon added Dogecoin to. Sometimes it thinks its dealing with Bitcoin still, so if you see anything odd, go and make sure you’ve selected Dogecoin in the Settings page.
This tool should be the only place you spend coins. Sure, some clients may look more convenient, but they all suffer from a very big coin-losing flaw. Whenever you split a UTXO, they create a new wallet to send the change to. And they DON’T TELL YOU! This means unless you back up after every transaction, you run a high risk of finding all your coins have ‘disappeared’ from your wallet, and you don’t recognise where they went. So if you use a client for the convenience as well as a text list of your wallets, you won’t know to add a new wallet to your masterfile. Its best to ditch the clients entirely.
Now we come to the nitty-gritty. Lets use those three wallets above and assume that #1 is the source, #2 the destination and #3 the change wallet. Note that these won’t actually work, as none of them have ever been used, but they will do as examples. New Transaction Located at the bottom of the New menu, this will give you a page to enter your wallets and amounts. In the top field, you enter your source address or Key. If you use the key, it will calculate the address when you click the Load button, which should match what you expected. Note that Load only brings in the first 100 UTXOs. This is so that you can retrieve coins from high-volume wallets which would kill any client. Coinb.in is in fact the ONLY WAY to do this, as even QT falls over around 600 UTXOs. You will see the total balance that was loaded in the Transaction Fee field. And also in the Inputs tab, where you can go to adjust which UTXOs to spend. Now you need to add the wallet(s) and amounts to send to them. Lets suppose the source contained a single UTXO for 1,000 Doge. You want to send 500 of them. So you would enter the #2 address in the Address field, and 500 in the Amount field. The Fee now changes to 500, which is not what you want. So you click the + button to bring up a new line, enter the change address and the other 500, making the fee zero. And you’re done. Check that the Fee is indeed zero. Check that the amounts shown in the Outputs and Inputs tabs match exactly.
THIS IS CRITICAL!
There is a bug which will send all the coins to the miners if the Outputs exceed the Inputs. I would have expected the Fee to show as negative in such a situation, but it doesn’t. BE WARNED! Once everything looks right, hit the Submit button. This will give you a block of hex code. Copy it. Sign Go to the Sign tab and paste it. Add your private key for the source wallet and click Submit. Note this can be done offline for safety. This will give you another block of hex, the SIGNED transaction. Broadcast Copy this and paste it in the Broadcast tab and click Submit. That’s it. Your coins are on their way. Make a cuppa and settle in while they arrive in a minute or three. Note: All fields retain their values unless you refresh the page! This can be a boon when doing multiple transactions, such as when emptying a huge wallet. But it can also be a trap for the unsuspecting. Refresh or close the window when you’re done.
Who should use this? Absolutely EVERYONE! Even if you’re wedded to your client in some satanic blood-contract, you should still know how this works, because sooner or later you’re going to have a problem you can’t fix without it. Definitely download the site and store it on every device you have. On every USB backup of your wallets. On your phone (well, except iOS which doesn’t do local HTML), etc, etc, etc. Oh, and if you’re a programmer SmartyShibe, do consider improving the code over on GitHub. EDIT:https://github.com/OutCast3k/coinbin added courtesy of AtomHearth
Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures. dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd. Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome. Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules. Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd. dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets. Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue) Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing. Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged. Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing. A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning. Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store. iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.". Nearest goal is to make the app crash free. Both mobile apps received new design themes. dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.". Up next is supporting dynamic page widths site wide and deploying new visual blocks home page. Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One). Ticket splitting: updated to use Go modules and added simnet support, several fixes. docs: beginner's guide overhaul, multiple fixes and cleanups. decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet. @Richard-Red is building a curated list of Decred-related GitHub repositories. Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus! Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)
Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate. Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply. Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.
Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example. A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1. Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks. Three more wallets integrated Decred in September:
Atomic desktop wallet added Decred in version 0.1.31. The team answered many questions on Reddit.
AnyBit wallet added Decred. It features built-in price and news tracking. Notably, the source code is open for their Android and iOS wallets.
Coboadded Decred support into their Android and iOS wallets.
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets. Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.
The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.
Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed. Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate.

If you have suggestions of events or conferences Decred should attend, please share them in #event_planning. In 2019, we would like to expand our presence in Europe, Asia, and South America, and we're looking for community members to help identify and staff those events. (@Dustorf)
August issue of Decred Journal was translated to Russian. Many thanks to @DZ! Rency cryptocurrency ratings published a report on Decred and incorporated a lot of feedback from the community on Reddit. September issue of Chinese CCID ratings was published (snapshot), Decred is still at the bottom. Videos:
The underbelly of blockchain Governance - fiat licensing and our code with Marco Peerboom and Chris DeRose (youtube, tweet, decred, missed in August issue) Insightful dialogue about men's underwear, licenses, subtleties of GPL, BSD wars, tiling window managers and much more.
Introduction to Decred (Korean, youtube) @Killawhale collected a lot of feedback from the community and produced this video to spread the word in Korea.

Decentralized autonomous funding of blockchain projects by @Richard-Red (medium, discussion on decred and dashpay)
The trouble with infrastructure, "thin" protocols in particular, is that someone has to build them at a cost. e.g. LN takes a ton of work, doesn't necessarily generate value itself, but it magnifies the value of BTC or whatever coin that uses it. I see the DEX in a similar light - whoever creates it is not going to make a bunch of money from it, but it will magnify the value of the underlying asset(s) that end up having a deep order book on the DEX. (@jy-p in #dex)
Twitter: why decentralized governance and funding are necessary for network survival and the power of controlling the narrative; learning about governance more broadly by watching its evolution in cryptocurrency space, importance of community consensus and communications infrastructure. Reddit: yet another strong pitch by @solar; question about buyer protections; dcrtime internals; a proposal to sponsor hoodies in the University of Cape Town; Lightning Network support for altcoins. Chats: skills to operate a stakepool; voting details: 2 of 3 votes can approve a block, what votes really approve are regular tx, etc; scriptless script atomic swaps using Schnorr adaptor signatures; dev dashboard, choosing work, people do best when working on what interests them most; opportunities for governments and enterprise for anchoring legal data to blockchain; terminology: DAO vs DAE; human-friendly payments, sharing xpub vs payment protocols; funding btcsuite development; Politeia vote types: approval vote, sentiment vote and a defund vote, also linking proposals and financial statements; algo trading and programming languages (yes, on #trading!); alternative implementation, C/C++/Go/Rust; HFTs, algo trading, fake volume and slippage; offline wallets, usb/write-only media/optical scanners vs auditing traffic between dcrd and dcrwallet; Proof of Activity did not inspire Decred but spurred Decred to get moving, Wikipedia page hurdles; how stakeholders could veto blocks; how many votes are needed to approve a proposal; why Decrediton uses Electron; CVE-2018-17144 and over-dependence on single Bitcoin implementation, btcsuite, fuzz testing; tracking proposal progress after voting and funding; why the wallet does not store the seed at all; power connectors, electricity, wiring and fire safety; reasonable spendings from project fund; ways to measure sync progress better than block height; using Politeia without email address; concurrency in Go, locks vs channels. #support is not often mentioned, but it must be noted that every day on this channel people get high quality support. (@bee: To my surprise, even those poor souls running Windows 10. My greatest respect to the support team!)
In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August. As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx) Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.
ASIC for Lyra2REv2 was spotted on the web. Vertcoin team is preparing a new PoW algorithm. This would be the 3rd fork after two previous forks to change the algorithm in 2014 and 2015. A report titled The Positive Externalities of Bitcoin Mining discusses the benefits of PoW mining that are often overlooked by the critics of its energy use. A Brief Study of Cryptonetwork Forks by Alex Evans of Placeholder studies the behavior of users, developers and miners after the fork, and makes the cases that it is hard for child chains to attract users and developers from their parent chains. New research on private atomic swaps: the paper "Anonymous Atomic Swaps Using Homomorphic Hashing" attempts to break the public link between two transactions. (bitcointalk, decred) On Sep 18 Poloniex announced delisting of 8 more assets. That day they took a 12-80% dive showing their dependence on this one exchange. Circle introduced USDC markets on Poloniex: "USDC is a fully collateralized US dollar stablecoin using the ERC-20 standard that provides detailed financial and operational transparency, operates within the regulated framework of US money transmission laws, and is reinforced by established banking partners and auditors.". Coinbase announced new asset listing process and is accepting submissions on their listing portal. (decred) The New York State Office of the Attorney General posted a study of 13 exchanges that contains many insights. A critical vulnerability was discovered and fixed in Bitcoin Core. Few days later a full disclosure was posted revealing the severity of the bug. In a bitcointalk thread btcd was called 'amateur' despite not being vulnerable, and some Core developers voiced their concerns about multiple implementations. The Bitcoin Unlimited developer who found the bug shared his perspective in a blog post. Decred's vision so far is that more full node implementations is a strength, just like for any Internet protocol.

Hello! At the moment, I don't use my Raspberry Pi for something usefull. A friend of my recommended that I could start mining Bitcoin. I have never done it before (Just some days on my computer. Manged to mine 0,00x something Bitcoin), and I wanted to try it out after reading this. I know that I am not able to generate that much Bitcoin, but I just want to start. As I said, I don't use it to anything else. Why not mining for Bitcoin? I have never done it before on Linux. My idea was to buy a USB Hub, a fan, and a lot of these. So, how would this actually work with the Raspberry? I am afraid that it's using a bit to much power than the Raspberry can handle. Fortunately, the USB Hub is powered. Can I buy two of these hubs, and then connect 9 miners on each? Is this actually possible? Do you have any great tutorials on how I can easily set up a miner on Raspberry Pi? Thank you very much!
Ordered 10 Block Erupters from BTCGuild... 3 died within a day
I was excited to start mining again after ditching GPU mining. Once the price dropped to 0.06 per, I ordered a set of 10. Plugged in 5 to two different computers (both modern systems with quality motherboards and high output USB ports with individual fuses). Right off the bat, one of them wouldn't mine. The light would turn green as soon as mining was attempted. Later that night, another went down. It just stopped after a while. Edit: Only 2 went down, not 3, but I will have to test them more to make sure Is this common? Is there a way I can troubleshoot this? I am not doing anything crazy with my miners, just plugging them into various USB ports, and mining. They aren't crowded or anything that would cause problems as far as I can tell.
Mega FAQ (Or: Please come here for your questions first)
Qbundle Guide (Step by step setup & Bootstrap) https://burstwiki.org/wiki/QBundle 1( I want to mine or activate My account. Where do find the multiple coins? You only need 1, an outgoing transaction or reward reassignment will set the public key. Get them from: https://www.reddit.com/burstcoinmining/comments/7q8zve/initial_burstcoin_requests/ Or (Faucet list) https://faucet.burstpay.net/ (if this is empty, come back later) http://faucet.burst-coin.es Or https://forums.getburst.net/c/new-members-introductions/getting-started-initial-burstcoin-requests 2( I bought coins on Bittrex and want to move to my new wallet, but can't. Why? Bittrex will only send to accounts with a public key (not a Burst requirement) so see number 1 and either set the name on the account (IF you will not mine) or set the reward recipient to the pool. Either action will enable the account and allow for transfers from Bittrex. 3( I sent coins from Poloniex/anywhere to Bittrex and they don’t show up after a considerable time. Why? You need to set an unencrypted message on the transaction, informing Bittrex which account to send the funds to (this is in the directions on Bittrex). Did you do this? Contact Bittrex support with all the details and eventually you will get your funds. 4( How much can I make on Burst? https://explore.burst.cryptoguru.org/tool/calculate Gives you an average over time assuming a few things like: Average luck/100% uptime/no overlapping/fees on pool/good plot scan time (<20 seconds) if you do not have all of these, you may not see that number. 5( If I use SSD’s would I make more money? No, it’s 95% capacity and 5% scan time that determine success. More plot area = better deadlines = better chance of forging a block, or better rates from a pool. 6( What is ‘solo’ and ‘pool’ (wasn’t his name Chewbacca?) Solo is where you attempt to ‘forge’ (mine) a block by yourself; you get 100% of the block reward and fees. But you only receive funds if you forge, no burst for coming in second place. Pools allow a group of miners to ‘pool’ together their resources and when a miner wins, they give the pool the winnings (this is done by the reward assignment you completed earlier), it is then divided according to different percentages and methods and burst is sent out according to pool rules (minimum pay-out, time, etc.) 7( I have been mining for 2 days and my wallet doesn’t show any Burst WHY? Mining solo: it is win-or-lose, nothing in between, and wining is luck and plot size. Pool mining: because it costs 1 burst to send burst, the pools have either a time requirement (every X days) or a minimum amount (100 burst +) so you need to research your pool. Some pools allow for you to set the limit (cryptoGuru and similar) to be met before sending 8( How do I see what I have pending? On CryptoGuru, based pools, it’s the ‘Pending (burst)’ column, other pools, look for the numbers next to your burst ID. One is Paid and the other pending. 9( I’m part of a pool and I forged a block, but I didn’t recieve the total value of the block, why? A pool has 2 basic numbers that denote the pay-out method, in the format ‘XX-XX’ (i.e. 50-50) The first number is the % paid to the block forger (miner) and the second is the retained value, which is paid to historic ‘shares’ (or, past blocks that the pool didn’t win, but had a miner that was ‘close’ to winning with a good submitted deadline) Examples of pools: 0-100 (good for <40TB) 20-80 (30-80TB) 50-50 (60-200TB) 80-20 (150-250) 100-0 (solo mine, 150+ TB) Please note that there is an overlap as this is personal preference and just guidance; a higher historical share value means a smoother pay-out regime, which some people prefer. If fees are not factored in, or are the same on different pools, the pay-out value will be the same over a long enough period. 10( Is XXX model of hard drive good? Which one do you recommend? CHEAP is best. If you have 2 new hard drives, both covered by warranty, get the one with the lowest cost per TB (expressed as $/TB , calculated by dividing the cost by the number of terabytes) because plot size is KING, 11( How many drives can I have on my machine? For best performance, you can have up to 2 drives per thread (3 on a new fast AVX2 CPU). So that quad-core core-2-quad can have up to 8 drives, but a more modern i7 with 4 cores + hyper threading can squeeze 8 * 3 or 24 drives. (Performance while scanning will suffer) 12( Can I game while I mine? Some people have done so, but you cannot have the ‘maximum’ number of drives and play games generally. 13( Can I mine Burst and GPU mine other coins? Yes, if you CPU Mine Burst. 14( I’m GPU plotting Burst and GPU mining another coin, my plots are being corrupted, why? My advice is dedicating a GPU to either mining or plotting, don’t try to do both. 15( What is a ‘plot’? A plot is a file that contains Hashes, these hashes are used to mine burst. A plot is tied to an account, but they can be created (with the same account ID) on other machines and connected back to your miner(s). 16( Where can I trade/buy/sell Burst? A list of exchanges is maintained on https://www.reddit.com/burstcoin/ (on the right, ‘Exchanges’ tab) the biggest at the moment are Bittrex and Poloniex, some offer direct Fiat-to-Burst purchase (https://indacoin.com for example) 17( Do I have to store my Burst off the exchange? No, but it’s safer from hackers who target exchanges, if you cannot guarantee the safety or security of your home computer from Trojans etc, then it might be best to leave on an exchange (but enable 2FA security on your account PLEASE!) 18( What security measures can I take to keep my coin safe? When you create an account, sign out and back in to your wallet (to make sure you have copied the pass phrase correctly) and keep multiple copies of the key (at least one physically printed or written down and in a safe place, better in 2 places) do not disclose the passphrase to anyone. Finally use either a local wallet or a trusted web wallet (please research before using any web wallet) 19( How can I help Burst? Run a wallet, which will act as a node (or if you’re a programmer, contact the Dev team Bring attention to burst (without ‘shilling’ or trying to get people to buy) And help translate into your local language Be a productive member of the community and contribute experience and knowledge if you can, or help others get into Burst. 20( Will I get coins on the fork(s) and where will they be? There will be no new coin, and no new coins to be given/air dropped etc, the forks are upgrades to burst and there will not be a ‘classic’ or ‘new’ burst. 21( Will I need to move my Burst off of the exchange for the fork? No, your transactions are on the block chain, which will be used on the fork, they will be visible after the move; nothing will need to be done on your side. 22( Where can I read about the progress of Burst and news in general on the community? There is no finer place than https://www.burstcoin.ist/ 23( What are the communities for Burst and the central website? Main website: https://www.burst-coin.org/ Reddit: https://www.reddit.com/burstcoin and https://www.reddit.com/burstcoinmining/ Burstforum.net: https://www.burstforum.net/ Getburst forum: https://forums.getburst.net/ Official Facebook channel: https://m.facebook.com/groups/398967360565392 (these are the forums that are known to be supporting the current Dev Team) Other ways to talk to the community: Discord: https://discordapp.com/invite/RPhpjVv Telegram (General): https://t.me/burstcoin Telegram (Mining): https://t.me/BurstCoinMining 24( When will Burst partner up with a company? Burst is a currency, the USD does not ‘partner up’ with a company, the DEV team will not partner up and give over to special interests. 25( Why is the DEV team anonymous? They prefer anonymity, as it allows them to work without constant scrutiny and questions unless they wish to engage, plus the aim is for Burst to become a major contender, and this brings issues with security. They will work and produce results, they owe you nothing and if you cannot see the vision they provide then please do not ‘invest’ for short term gain. 26( When moon/Lambo/$100/make me rich? My crystal ball is still broken, come back to the FAQ later for answer (seriously, this is a coin to hold, if you want to day-trade, good luck to you) 27( How can I better educate myself and learn about Dymaxion? Read about the Dymaxion here: https://www.reddit.com/burstcoin/wiki/dymaxion 28( My reads are slow, why? There are many reasons for this, if your computer has a decent spec it’s likely due to USB3 hub issues, or plugging into a USB2 hub, but other reasons can be multiple plots in the same folder, but it’s best to visit the mining subreddit. They can help more than an simple FAQ https://www.reddit.com/burstcoinmining/ 29( I have a great idea for Burst (not proof of stake related)? Awesome! Please discuss with the DEV team on discord https://discordapp.com/invite/RPhpjVv (Please be aware that this is a public forum, you need to find who to ask/tell) 30( I have a great idea for Burst (Proof of stake related)? No. if you want a POS, find a POS coin. On the tangle which is being implemented a POS/POW/POC coin can be created, but BURST will always be POC mined. You are welcome to implement a proof of stake coin on this! 31( Will the Dev team burn any coins? Burst is not an ICO, so any coins will need to be bought to be burnt. You are welcome to donate, but the DEV team have no intention of burning any coins, or increasing the coin cap. 32( When will there be an IOS wallet? IOS wallet is completed; we are waiting for it to go on the app store. Apple is the delaying factor. 33( Why do overlapping plots matter? Plots are like collections of lottery tickets (and if only one ticket could win). Having 2 copies is not useful, and it means that you have less coverage of ‘all’ the possible numbers. It’s not good, avoid. 34( My local wallet used to run, I synchronised it before and now it says ‘stopped’. when I start it, it stops after a few seconds, what should I do? I suggest that you change the database type to portable MariaDB (on Qbundle, at the top, ‘Database’ select, ‘change database’) and then re-import the database from scratch (see 35) 35( Synchronising the block chain is slow and I have the patience of a goldfish. What can I do? On Qbundle , ‘Database’ select ‘Bootstrap chain’ and make sure the CryptoGuru repository is selected, then ‘start Import’ this will download and quickly stuff the local database (I suggest Portable MariaDB, see 34) (lol, loop) 36( What will the block reward be next month/will the block rewards run out in 6 months? https://www.ecomine.earth/burstblockreward/ Rewards will carry on into 2026, but transaction fees will be a bigger % by then, and so profitable mining will continue. 37( How can I get started with Burst (wallet/mining/everything) and I need it in a video https://www.youtube.com/watch?v=LJLhw37Lh_8 Watch and be enlightened. 38( Can I mine on multiple machines with the same account? Yes, if you want to pool mine this can be done (but be prepared for small issues like reported size being incorrect. Just be sure to keep question 33 in mind.) 39( Why do some of my drives take forever to plot? Most likely they are SMR drives, it’s best to plot onto another SSD and then move the finished plot/part of a plot across to the SMR drive as this is much quicker. SMR drives are fine on the read, just random writes that are terrible. So plot an SMR drive quickly, plot to a non SMR or better still SSD drive, in as big a chunk as possible (fewer files better) and move. a version of Xplotter, called Splotter, can do this easily. https://github.com/NoParamedic/SPlotter 40( I have a great idea; why not get listed on more exchanges!! Exchanges list coins because of 2 reasons:
The coin pays (often A LOT, seriously we’ve been asked for 50 BTC)
I suggest you speak with your exchange and ask ‘when will they offer Burst?’ 41( Do you have a roadmap? https://www.burst-coin.org/roadmap 42( Why is the price of Burst going up/down/sideways/looping through time? The price of burst is still quite dependent upon Bitcoin, meaning that if Bitcoin gains, the value of Burst gains, if Bitcoin drops then Burst also drops. If there is news for Burst then we will see something independent of Bitcoin moving. Variations can be because of people buying in bulk or selling in bulk. There are also ‘pump and dump’ schemes that we detest, that can cause spikes in price that have nothing to do with news or Bitcoin, just sad people taking advantage of others. 43( Where is the best place to go with my mining questions? https://www.reddit.com/burstcoinmining/ or https://t.me/BurstCoinMining 44( What hardware do you advise me to buy, is this computer good? See question 43 for specific questions on hardware, it depends on so many variables. The ‘best’ in my opinion is a 36 bay Supermicro storage server, usually they have dual 6-core CPU’s and space for 36 drives. No USB cables, plotting and mining monster, anything else, DYOR. 45( Where do you buy your hard drives? I have bought most from EBay in job lots, and some refurbished drives with short warranties. Everything else I have bought, from Amazon. 46( Can I mine on my Google drive/cloud based storage? In short: no. If you want to try, and get to maybe 1 TB and then find that your local connection isn’t fast enough, or that shortly after, your account is blocked for various reasons. Please be my guest. 47( Can I mine on my NAS? Some you can mine with the NAS (if it can run the miner, it can scan locally) but generally they’re not very fast. good for maybe 16 TB? Having a plot on a NAS and mining from another computer depends on the network speed between the NAS and scanning computer. I believe you can scan about 8 TB (maybe a bit more) and keep the scan times to within acceptable, but YMMV. 48( How can I set up a node? No need to set up a node, just set up a wallet (version 2.0.4) or Qbundle (2.2) and it will do the rest 49( Are the passphrases secured? I’ll leave the effort to a few people to show how secure a 12-word passphrase is: https://burstforum.net/topic/4766/the-canary-burst-early-warning-system Key point: brute forcing it will be around 13,537,856,339,904,134,474,012,675,034 years. 50( I logged into my account (maybe with a different burst ID) and see no balance!! I have dealt with this very issue multiple times, and there are only 3 options:
You have typed in the password incorrectly
You have copy-pasted the password incorrectly
You are trying to log into a ‘local wallet’ which the block chain has not finished updating
Bitcoin, huh? WTF is going on? Should we scale you on-chain or off-chain? Will you stay decentralized, distributed, immutable?
0. Shit, this is long, TLWR please! Too long, won't read. EDIT: TLDR TLWR for clarity.
Bitcoin is a decentralized, distributed, immutable network. It has users, nodes, and miners, all of which participate in building a public and pseudonymous ledger of blocks called blockchain. The blockchain requires its own currency to function and this currency is called Bitcoin.
The bitcoin network is going through growing pains. Some believe that it should be scaled on-chain with high-volume-low-cost transaction fees, whereas others believe that it has to be scaled off-chain with low-volume-high-cost transaction fees and more affordable second layer solutions. Each have relative advantages and disadvantages. A compromise has not been reached yet.
The off-chain scaling solution via Bitcoin Core SegWit’s lightning network diminishes distributed and immutable network properties. It replaces bitcoin’s peer-to-peer network with a two-layer institution-to-institution network and peer-to-hub-to-peer second layer solution.
The on-chain scaling solution via Bitcoin Cash’s increased block size limit is feasible at the moment but inefficient in the long run. It could be merged with several good concepts from the lightning network proposal and new ideas outlined in this overview.
An appropriate scaling analogy is to recall email attachments early on. They too were limited to a few MB at first, then 10MB, 20MB, up until 25MB on Gmail. But even then, Gmail eventually started using Google Drive internally.
Similarly, any second layer solutions should be integrated within the existing bitcoin network secured by miners and nodes. The revenue from any second layer solutions should be redistributed internally to miners and nodes, not to additional third party hubs which the lightning network envisions.
The author of this overview recommends on-chain scaling for the time being, with the understanding that off-chain scaling should be implemented as soon as possible, as long as these second layer solutions keep the bitcoin peer-to-peer and decentralized, distributed, immutable. Unfortunately, the lightning network does not accomplish this.
The author remains impartial to Bitcoin Core and Bitcoin Cash proposals, with a preference for Bitcoin Cash’s way of handling immutability and overall progress thus far.
1. Bitcoin, huh? Brief introduction. There are 3 sections to this overview. The first section is a brief introduction to bitcoin. The second section looks at recent developments in the bitcoin world, through the analogy of email attachments, and the third section discusses what could be next, through the perspective of resilience and network security. This is just a continuation of a long, long, possibly never-ending debate that started with the release of the bitcoin whitepaper in 2008 (see https://bitcoin.org/bitcoin.pdf). The recent mess during the past few years boils down to the controversy with the block size limit and how to appropriately scale bitcoin, the keyword appropriately. Scaling bitcoin is a controversial debate with valid arguments from all sides (see https://en.bitcoin.it/wiki/Block_size_limit_controversy). I have researched, studied, and written this overview as objectively and as impartially as possible. By all means, this is still an opinion and everyone is advised to draw their own conclusions. My efforts are to make at least a few readers aware that ultimately there is only one team, and that team is the team bitcoin. Yes, currently though, there are factions within the team bitcoin. I hope that we can get beyond partisan fights and work together for the best bitcoin. I support all scaling proposals as long as they are the best for the given moment in time. Personally, I hate propaganda and love free speech as long as it is not derogatory and as long as it allows for constructive discussions. The goal of this overview is to explain to a novice how bitcoin network works, what has been keeping many bitcoin enthusiasts concerned, and if we can keep the bitcoin network with three main properties described as decentralized, distributed, immutable. Immutable means censorship resistant. For the distinction between decentralized and distributed, refer to Figure 1: Centralized, decentralized and distributed network models by Paul Baran (1964), which is a RAND Institute study to create a robust and nonlinear military communication network (see https://www.rand.org/content/dam/rand/pubs/research_memoranda/2006/RM3420.pdf). Note that for the overall network resilience and security, distributed is more desirable than decentralized, and the goal is to get as far away from central models as possible. Of course, nothing is strictly decentralized or strictly distributed and all network elements are at different levels of this spectrum. For those unaware how bitcoin works, I recommend the Bitcoin Wikipedia (see https://en.bitcoin.it/wiki/Main_Page). In short, the bitcoin network includes users which make bitcoin transactions and send them to the network memory pool called mempool, nodes which store the public and pseudonymous ledger called blockchain and which help with receiving pending transactions and updating processed transactions, thus securing the overall network, and miners which also secure the bitcoin network by mining. Mining is the process of confirming pending bitcoin transactions, clearing them from the mempool, and adding them to blocks which build up the consecutive chain of blocks on the blockchain. The blockchain is therefore a decentralized and distributed ledger built on top of bitcoin transactions, therefore impossible to exist without bitcoin. If someone claims to be working on their own blockchain without bitcoin, by the definition of the bitcoin network however, they are not talking about the actual blockchain. Instead, they intend to own a different kind of a private database made to look like the public and pseudonymous blockchain ledger. There are roughly a couple of dozen mining pools, each possibly with hundreds or thousands of miners participating in them, to several thousand nodes (see https://blockchain.info/pools and https://coin.dance/nodes). Therefore, the bitcoin network has at worst decentralized miners and at best distributed nodes. The miner and node design makes the blockchain resilient and immune to reversible changes, making it censorship resistant, thus immutable. The bitcoin blockchain avoids the previous need for a third party to trust. This is a very elegant solution to peer-to-peer financial exchange via a network that is all: decentralized, distributed, immutable. Extra features (escrow, reversibility via time-locks, and other features desirable in specific instances) can be integrated within the network or added on top of this network, however, they have not been implemented yet. Miners who participate receive mining reward consisting of newly mined bitcoins at a predetermined deflationary rate and also transaction fees from actual bitcoin transactions being processed. It is estimated that in 2022, miners will have mined more than 90% of all 21 million bitcoins ever to be mined (see https://en.bitcoin.it/wiki/Controlled_supply). As the mining reward from newly mined blocks diminishes to absolute zero in 2140, the network eventually needs the transaction fees to become the main component of the reward. This can happen either via high-volume-low-cost transaction fees or low-volume-high-cost transaction fees. Obviously, there is the need to address the question of fees when dealing with the dilemma how to scale bitcoin. Which type of fees would you prefer and under which circumstances? 2. WTF is going on? Recent developments. There are multiple sides to the scaling debate but to simplify it, first consider the 2 main poles. In particular, to scale bitcoin on blockchain or to scale it off it, that is the question! The first side likes the idea of bitcoin as it has been until now. It prefers on-chain scaling envisioned by the bitcoin creator or a group of creators who chose the pseudonym Satoshi Nakamoto. It is now called Bitcoin Cash and somewhat religiously follows Satoshi’s vision from the 2008 whitepaper and their later public forum discussions (see https://bitcointalk.org/index.php?topic=1347.msg15366#msg15366). Creators’ vision is good to follow but it should not be followed blindly and dogmatically when better advancements are possible, the keyword when. To alleviate concerning backlog of transactions and rising fees, Bitcoin Cash proponents implemented a simple one-line code update which increased the block size limit for blockhain blocks from 1MB block size limit to a new, larger 8MB limit. This was done through a fork on August 1, 2017, which created Bitcoin Cash, and which kept the bitcoin transaction history until then. Bitcoin Cash has observed significant increase in support, from 3% of all bitcoin miners at first to over 44% of all bitcoin miners after 3 weeks on August 22, 2017 (see http://fork.lol/pow/hashrate and http://fork.lol/pow/hashrateabs). An appropriate scaling analogy is to recall email attachments early on. They too were limited to a few MB at first, then 10MB, 20MB, up until 25MB on Gmail. But even then, Gmail eventually started using Google Drive internally. Note that Google Drive is a third party to Gmail, although yes, it is managed by the same entity. The second side argues that bitcoin cannot work with such a scaling approach of pre-meditated MB increases. Arguments against block size increases include miner and node centralization, and bandwidth limitations. These are discussed in more detail in the third section of this overview. As an example of an alternative scaling approach, proponents of off-chain scaling want to jump to the internally integrated third party right away, without any MB increase and, sadly, without any discussion. Some of these proponents called one particular implementation method SegWit, which stands for Segregated Witness, and they argue that SegWit is the only way that we can ever scale up add the extra features to the bitcoin network. This is not necessarily true because other scaling solutions are feasible, such as already functioning Bitcoin Cash, and SegWit’s proposed solution will not use internally integrated third party as shown next. Note that although not as elegant as SegWit is today, there are other possibilities to integrate some extra features without SegWit (see /Bitcoin/comments/5dt8tz/confused_is_segwit_needed_for_lightning_network). Due to the scaling controversy and the current backlog of transactions and already high fees, a third side hastily proposed a compromise to a 2MB increase in addition to the proposed SegWit implementation. They called it SegWit2x, which stands for Segregated Witness with 2MB block size limit increase. But the on-chain scaling and Bitcoin Cash proponents did not accept it due to SegWit’s design redundancy and hub centralization which are discussed next and revisited in the third section of this overview. After a few years of deadlock, that is why the first side broke free and created the Bitcoin Cash fork. The second side stuck with bitcoin as it was. In a way, they inherited the bitcoin network without any major change to public eye. This is crucial because major changes are about to happen and the original bitcoin vision, as we have known it, is truly reflected only in what some media refer to as a forked clone, Bitcoin Cash. Note that to avoid confusion, this second side is referred to as Bitcoin Core by some or Legacy Bitcoin by others, although mainstream media still refers to it simply as Bitcoin. The core of Bitcoin Core is quite hardcore though. They too rejected the proposed compromise for SegWit2x and there are clear indications that they will push to keep SegWit only, forcing the third side with SegWit2x proponents to create another fork in November 2017 or to join Bitcoin Cash. Note that to certain degree, already implemented and working Bitcoin Cash is technically superior to SegWit2x which is yet to be deployed (see /Bitcoin/comments/6v0gll/why_segwit2x_b2x_is_technically_inferior_to). Interestingly enough, those who agreed to SegWit2x have been in overwhelming majority, nearly 87% of all bitcoin miners on July 31, 2017 prior to the fork, and a little over 90% of remaining Bitcoin Core miners to date after the fork (see https://coin.dance/blocks). Despite such staggering support, another Bitcoin Core fork is anticipated later in November (see https://cointelegraph.com/news/bitcoin-is-splitting-once-again-are-you-ready) and the "Outcome #2: Segwit2x reneges on 2x or does not prioritize on-chain scaling" seems to be on track from the perspective of Bitcoin Core SegWit, publicly seen as the original Bitcoin (see https://blog.bridge21.io/before-and-after-the-great-bitcoin-fork-17d2aad5d512). The sad part is that although in their overwhelming majority, the miners who support SegWit2x would be the ones creating another Bitcoin Core SegWit2x fork or parting ways from the original Bitcoin. In a way, this is an ironic example how bitcoin’s built-in resiliency to veto changes causes majority to part away when a small minority has status quo and holds off fully-consented progress. Ultimately, this will give the minority Bitcoin Core SegWit proponents the original Bitcoin branding, perhaps to lure in large institutional investors and monetize on bitcoin’s success as we have it seen it during the past 9 years since its inception. Recall that bitcoin of today is already a decentralized, distributed, immutable network by its definition. The bitcoin network was designed to be an alternative to centralized and mutable institutions, so prevalent in modern capitalist societies. Bitcoin Core SegWit group wants to change the existing bitcoin network to a network with dominant third parties which, unlike Google Drive to Gmail, are not internal. In particular, they intend to do so via the lightning network, which is a second layer solution (2L). This particular 2L as currently designed relies on an artificial block size limit cap which creates a bottleneck in order to provide high incentives for miners to participate. It monetizes on backlog of transaction and high fees, which are allocated to miners, not any group in particular. Cheaper and more instantaneous transactions are shifted to the lightning network which is operated by hubs also earning revenue. Note that some of these hubs may choose to monitor transactions and can possibly censor who is allowed to participate in this no longer strictly peer-to-peer network. We lose the immutability and instead we have a peer-to-hub-to-peer network that is mutable and at best decentralized, and certainly not distributed (see https://medium.com/@jonaldfyookball/mathematical-proof-that-the-lightning-network-cannot-be-a-decentralized-bitcoin-scaling-solution-1b8147650800). For regular day-to-day and recurring transactions, it is not a considerable risk or inconvenience. And one could choose to use the main chain any time to bypass the lightning network and truly transact peer-to-peer. But since the main chain has an entry barrier in the form of artificially instilled high transaction fees, common people are not able to use bitcoin as we have known it until now. Peer-to-peer bitcoin becomes institution-to-institution bitcoin with peer-to-hub-to-peer 2L. To reiterate and stress, note the following lightning network design flaw again. Yes, activating SegWit and allowing 2L such as lightning allows for lower transaction fees to coexist side by side with more costly on-chain transactions. For those using this particularly prescribed 2L, the fees remain low. But since these 2L are managed by hubs, we introduce another element to trust, which is contrary to what the bitcoin network was designed to do at the first place. Over time, by the nature of the lightning network in its current design, these third party hubs grow to be centralized, just like Visa, Mastercard, Amex, Discover, etc. There is nothing wrong with that in general because it works just fine. But recall that bitcoin set out to create a different kind of a network. Instead of decentralized, distributed, immutable network with miners and nodes, with the lightning network we end up with at best decentralized but mutable network with hubs. Note that Bitcoin Core SegWit has a US-based organization backing it with millions of dollars (see https://en.wikipedia.org/wiki/Blockstream and https://steemit.com/bitcoin/@adambalm/the-truth-about-who-is-behind-blockstream-and-segwit-as-the-saying-goes-follow-the-money). Their proponents are quite political and some even imply $1000 fees on the main bitcoin blockchain (see https://cointelegraph.com/news/ari-paul-tuur-demeester-look-forward-to-up-to-1k-bitcoin-fees). Contrary to them, Bitcoin Cash proponents intend to keep small fees on a scale of a few cents, which in large volume in larger blockchain blocks provide sufficient incentive for miners to participate. On the one hand, sticking to the original vision of peer-to-peer network scaled on-chain has merit and holds potential for future value. On the other hand, 2L have potential to carry leaps forward from current financial infrastructure. As mentioned earlier, 2L will allow for extra features to be integrated off-chain (e.g. escrow, reversibility via time-locks), including entirely new features such as smart contracts, decentralized applications, some of which have been pioneered and tested on another cryptocurrency network called Ethereum. But such features could be one day implemented directly on the main bitcoin blockchain without the lightning network as currently designed, or perhaps with a truly integrated 2L proposed in the third section of this overview. What makes the whole discussion even more confusing is that there are some proposals for specific 2L that would in fact increase privacy and make bitcoin transactions less pseudonymous than those on the current bitcoin blockchain now. Keep in mind that 2L are not necessarily undesirable. If they add features and keep the main network characteristics (decentralized, distributed, immutable), they should be embraced with open arms. But the lightning network as currently designed gives up immutability and hub centralization moves the network characteristic towards a decentralized rather than a distributed network. In a sense, back to the initial email attachment analogy, even Gmail stopped with attachment limit increases and started hosting large files on Google Drive internally, with an embedded link in a Gmail email to download anything larger than 25MB from Google Drive. Anticipating the same scaling decisions, the question then becomes not if but when and how such 2L should be implemented, keeping the overall network security and network characteristics in mind. If you have not gotten it yet, repeat, repeat, repeat: decentralized, distributed, immutable. Is it the right time now and is SegWit (one way, my way or highway) truly the best solution? Those siding away from Bitcoin Core SegWit also dislike that corporate entities behind Blockstream, the one publicly known corporate entity directly supporting SegWit, have allegedly applied for SegWit patents which may further restrict who may and who may not participate in the creation of future hubs, or how these hubs are controlled (see the alleged patent revelations, https://falkvinge.net/2017/05/01/blockstream-patents-segwit-makes-pieces-fall-place, the subsequent Twitter rebuttal Blockstream CEO, http://bitcoinist.com/adam-back-no-patents-segwit, and the subsequent legal threats to SegWit2x proponents /btc/comments/6vadfi/blockstream_threatening_legal_action_against). Regardless if the patent claims are precise or not, the fact remains that there is a corporate entity dictating and vetoing bitcoin developments. Objectively speaking, Bitcoin Core SegWit developers paid by Blockstream is a corporate takeover of the bitcoin network as we have known it. And on the topic of patents and permissionless technological innovations, what makes all of this even more complicated is that a mining improvement technology called ASICboost is allowed on Bitcoin Cash. The main entities who forked from Bitcoin Core to form Bitcoin Cash had taken advantage of patents to the ASICboost technology on the original bitcoin network prior to the fork (see https://bitcoinmagazine.com/articles/breaking-down-bitcoins-asicboost-scandal). This boost saved estimated 20% electricity for miners on 1MB blocks and created unfair economic advantage for this one particular party. SegWit is one way that this boost is being eliminated, through the code. Larger blocks are another way to reduce the boost advantage, via decreased rate of collisions which made this boost happen at the first place (see https://bitcoinmagazine.com/articles/breaking-down-bitcoins-asicboost-scandal-solutions and https://bitslog.wordpress.com/2017/04/10/the-relation-between-segwit-and-asicboost-covert-and-overt). Therefore, the initial Bitcoin Cash proponents argue that eliminating ASICboost through the code is no longer needed or necessary. Of course, saving any amount electricity between 0% and 20% is good for all on our planet but in reality any energy saved in a mining operation is used by the same mining operation to increase their mining capacity. In reality, there are no savings, there is just capacity redistribution. The question then becomes if it is okay that only one party currently and already holds onto this advantage, which they covertly hid for relatively long time, and which they could be using covertly on Bitcoin Cash if they desired to do so, even though it would an advantage to a smaller degree. To be fair to them, they are mining manufacturers and operators, they researched and developed the advantage from own resources, so perhaps they do indeed have the right to reap ASICboost benefits while they can. But perhaps it should happen in publicly know way, not behind closed doors, and should be temporary, with agreed patent release date. In conclusion, there is no good and no bad actor, each side is its own shade of grey. All parties have their own truth (and villainy) to certain degree. Bitcoin Cash's vision is for bitcoin to be an electronic cash platform and daily payment processor whereas Bitcoin Core SegWit seems to be drawn more to the ideas of bitcoin as an investment vehicle and a larger settlement layer with the payment processor function managed via at best decentralized third party hubs. Both can coexist, or either one can eventually prove more useful and digest the other one by taking over all use-cases. Additionally, the most popular communication channel on /bitcoin with roughly 300k subscribers censors any alternative non-Bitcoin-Core-SegWit opinions and bans people from posting their ideas to discussions (see https://medium.com/@johnblocke/a-brief-and-incomplete-history-of-censorship-in-r-bitcoin-c85a290fe43). This is because their moderators are also supported by Blockstream. Note that the author of this overview has not gotten banned from this particular subreddit (yet), but has experienced shadow-banning first hand. Shadow-banning is a form of censorship. In this particular case, their moderator robot managed by people moderators, collaboratively with the people moderators, do the following:
(1) look for "Bitcoin Cash" and other undesirable keywords,
(2) warn authors that “Bitcoin Cash” is not true bitcoin (which objectively speaking it is, and which is by no means “BCash” that Bitcoin Core SegWit proponents refer to, in a coordinated effort to further confuse public, especially since some of them have published plans to officially release another cryptocurrency called “BCash” in 2018, see https://medium.com/@freetrade68/announcing-bcash-8b938329eaeb),
(3) further warn authors that if they try to post such opinions again, they could banned permanently,
(4) tell authors to delete their already posted posts or comments,
(5) hide their post from publicly seen boards with all other posts, thus preventing it from being seeing by the other participants in this roughly 300k public forum,
This effectively silences objective opinions and creates a dangerous echo-chamber. Suppressing free speech and artificially blowing up transaction fees on Bitcoin Core SegWit is against bitcoin’s fundamental values. Therefore, instead of the original Reddit communication channel, many bitcoin enthusiasts migrated to /btc which has roughly 60k subscribers as of now, up from 20k subscribers a year ago in August 2016 (see http://redditmetrics.com/btc). Moderators there do not censor opinions and allow all polite and civil discussions about scaling, including all opinions on Bitcoin Cash, Bitcoin Core, etc. Looking beyond their respective leaderships and communication channels, let us review a few network fundamentals and recent developments in Bitcoin Core and Bitcoin Cash networks. Consequently, for now, these present Bitcoin Cash with more favorable long-term prospects.
(1) The stress-test and/or attack on the Bitcoin Cash mempool earlier on August 16, 2017 showed that 8MB blocks do work as intended, without catastrophic complications that Bitcoin Core proponents anticipated and from which they attempted to discourage others (see https://jochen-hoenicke.de/queue/uahf/#2w for the Bitcoin Cash mempool and https://core.jochen-hoenicke.de/queue/#2w for the Bitcoin Core mempool). Note that when compared to the Bitcoin Core mempool on their respective 2 week views, one can observe how each network handles backlogs. On the most recent 2 week graphs, the Y-scale for Bitcoin Core is 110k vs. 90k on Bitcoin Cash. In other words, at the moment, Bitcoin Cash works better than Bitcoin Core even though there is clearly not as big demand for Bitcoin Cash as there is for Bitcoin Core. The lack of demand for Bitcoin Cash is partly because Bitcoin Cash is only 3 weeks old and not many merchants have started accepting it, and only a limited number of software applications to use Bitcoin Cash has been released so far. By all means, the Bitcoin Cash stress-test and/or attack from August 16, 2017 reveals that the supply will handle the increased demand, more affordably, and at a much quicker rate.
(2) Bitcoin Cash “BCH” mining has become temporarily more profitable than mining Bitcoin Core “BTC” (see http://fork.lol). Besides temporary loss of miners, this puts Bitcoin Core in danger of permanently fleeing miners. Subsequently, mempool backlog and transaction fees are anticipated to increase further.
(3) When compared to Bitcoin Cash transaction fees at roughly $0.02, transaction fees per kB are over 800 times as expensive on Bitcoin Core, currently at over $16 (see https://cashvscore.com).
(4) Tipping service that used to work on Bitcoin Core's /Bitcoin a few years back has been revived by a new tipping service piloted on the more neutral /btc with the integration of Bitcoin Cash (see /cashtipperbot).
3. Should we scale you on-chain or off-chain? Scaling bitcoin. Let us start with the notion that we are impartial to both Bitcoin Core (small blocks, off-chain scaling only) and Bitcoin Cash (big blocks, on-chain scaling only) schools of thought. We will support any or all ideas, as long as they allow for bitcoin to grow organically and eventually succeed as a peer-to-peer network that remains decentralized, distributed, immutable. Should we have a preference in either of the proposed scaling solutions? First, let us briefly address Bitcoin Core and small blocks again. From the second section of this overview, we understand that there are proposed off-chain scaling methods via second layer solutions (2L), most notably soon-to-be implemented lightning via SegWit on Bitcoin Core. Unfortunately, the lightning network diminishes distributed and immutable network properties by replacing bitcoin’s peer-to-peer network with a two-layer institution-to-institution network and peer-to-hub-to-peer 2L. Do we need this particular 2L right now? Is its complexity truly needed? Is it not at best somewhat cumbersome (if not very redundant)? In addition to ridiculously high on-chain transaction fees illustrated in the earlier section, the lightning network code is perhaps more robust than it needs to be now, with thousands of lines of code, thus possibly opening up to new vectors for bugs or attacks (see https://en.bitcoin.it/wiki/Lightning_Network and https://github.com/lightningnetwork/lnd). Additionally, this particular 2L as currently designed unnecessarily introduces third parties, hubs, that are expected to centralize. We already have a working code that has been tested and proven to handle 8MB blocks, as seen with Bitcoin Cash on August 16, 2017 (see https://www.cryptocoinsnews.com/first-8mb-bitcoin-cash-block-just-mined). At best, these third party hubs would be decentralized but they would not be distributed. And these hubs would be by no means integral to the original bitcoin network with users, nodes, and miners. To paraphrase Ocam’s razor problem solving principle, the simplest solution with the most desirable features will prevail (see https://en.wikipedia.org/wiki/Occam%27s_razor). The simplest scalability solution today is Bitcoin Cash because it updates only one line of code, which instantly increases the block size limit. This also allows other companies building on Bitcoin Cash to reduce their codes when compared to Bitcoin Core SegWit’s longer code, some even claiming ten-fold reductions (see /btc/comments/6vdm7y/ryan_x_charles_reveals_bcc_plan). The bitcoin ecosystem not only includes the network but it also includes companies building services on top of it. When these companies can reduce their vectors for bugs or attacks, the entire ecosystem is healthier and more resilient to hacking disasters. Obviously, changes to the bitcoin network code are desirable to be as few and as elegant as possible. But what are the long-term implications of doing the one-line update repeatedly? Eventually, blocks would have to reach over 500MB size if they were to process Visa-level capacity (see https://en.bitcoin.it/wiki/Scalability). With decreasing costs of IT infrastructure, bandwidth and storage could accommodate it, but the overhead costs would increase significantly, implying miner and/or full node centralization further discussed next. To decrease this particular centralization risk, which some consider undesirable and others consider irrelevant, built-in and integrated 2L could keep the block size at a reasonably small-yet-still-large limit. At the first sight, these 2L would remedy the risk of centralization by creating their own centralization incentive. At the closer look and Ocam’s razor principle again, these 2L do not have to become revenue-seeking third party hubs as designed with the current lightning network. They can be integrated into the current bitcoin network with at worst decentralized miners and at best distributed nodes. Recall that miners will eventually need to supplement their diminishing mining reward from new blocks. Additionally, as of today, the nodes have no built-in economic incentive to run other than securing the network and keeping the network’s overall value at its current level. Therefore, if new 2L were to be developed, they should be designed in a similar way like the lightning network, with the difference that the transaction processing revenue would not go to third party hubs but to the already integrated miners and nodes. In other words, why do we need extra hubs if we have miners and nodes already? Let us consider the good elements from the lightning network, forget the unnecessary hubs, and focus on integrating the hubs’ responsibilities to already existing miner and node protocols. Why would we add extra elements to the system that already functions with the minimum number of elements possible? Hence, 2L are not necessarily undesirable as long as they do not unnecessarily introduce third party hubs. Lastly, let us discuss partial on-chain scaling with the overall goal of network security. The network security we seek is the immutability and resilience via distributed elements within otherwise decentralized and distributed network. It is not inconceivable to scale bitcoin with bigger blocks as needed, when needed, to a certain degree. The thought process is the following:
(1) Block size limit:
We need some upper limit to avoid bloating the network with spam transactions. Okay, that makes sense. Now, what should this limit be? If we agree to disagree with small block size limit stuck at 1MB, and if we are fine with flexible block size limit increases (inspired by mining difficulty readjustments but on a longer time scale) or big block propositions (to be increased incrementally), what is holding us off next?
(2) Miner centralization:
Bigger blocks mean that more data will be transferred on the bitcoin network. Consequently, more bandwidth and data storage will be required. This will create decentralized miners instead of distributed ones. Yes, that is true. And it has already happened, due to the economy of scale, in particular the efficiency of grouping multiple miners in centralized facilities, and the creation of mining pools collectively and virtually connecting groups of miners not physically present in the same facility. These facilities tend to have huge overhead costs and the data storage and bandwidth increase costs are negligible in this context. The individual miners participating in mining pools will quite likely notice somewhat higher operational costs but allowing for additional revenue from integrated 2L described earlier will give them economic incentive to remain actively participating. Note that mining was never supposed to be strictly distributed and it was always at worst decentralized, as defined in the first section of this overview. To assure at best a distributed network, we have nodes.
(3) Node centralization:
Bigger blocks mean that more data will be transferred on the bitcoin network. Consequently, more bandwidth and data storage will be required. This will create decentralized nodes instead of distributed ones. Again, recall that we have a spectrum of decentralized and distributed networks in mind, not their absolutes. The concern about the node centralization (and the subsequent shift from distributed to decentralized network property) is valid if we only follow on-chain scaling to inconsiderate MB values. If addressed with the proposed integrated 2L that provides previously unseen economic incentives to participate in the network, this concern is less serious. Furthermore, other methods to reduce bandwidth and storage needs can be used. A popular proposal is block pruning, which keeps only the most recent 550 blocks, and eventually deletes any older blocks (see https://news.bitcoin.com/pros-and-cons-on-bitcoin-block-pruning). Block pruning addresses storage needs and makes sure that not all nodes participating in the bitcoin network have to store all transactions that have ever been recorded on the blockchain. Some nodes storing all transactions are still necessary and they are called full nodes. Block pruning does not eliminate full nodes but it does indeed provide an economic incentive for the reduction and centralization (i.e. saving on storage costs). If addressed with the proposed integrated 2L that provides previously unseen economic incentives to participate in the network, this concern is less serious. In other words, properly designed 2L should provide economic incentives for all nodes (full and pruned) to remain active and distributed. As of now, only miners earn revenue for participating. The lightning network proposes extra revenue for hubs. Instead, miner revenue could increase by processing 2L transactions as well, and full nodes could have an economic incentive as well. To mine, relatively high startup costs is necessary in order to get the most up to date mining hardware and proper cooling equipment. These have to be maintained and periodically upgraded. To run a full node, one needs only stable bandwidth and a sufficiently large storage, which can be expanded as needed, when needed. To run a full node, one needs only stable bandwidth and relatively small storage, which does not need to be expanded. Keeping the distributed characteristic in mind, it would be much more secure for the bitcoin network if one could earn bitcoin by simply running a node, full or pruned. This could be integrated with a simple code change requiring each node to own a bitcoin address to which miners would send a fraction of processed transaction fees. Of course, pruned nodes would collectively receive the least transaction fee revenue (e.g. 10%), full nodes would collectively receive relatively larger transaction fee revenue (e.g. 20%), whereas mining facilities or mining pools would individually receive the largest transaction fee revenue (e.g. 70%) in addition to the full mining reward from newly mined blocks (i.e. 100%). This would assure that all nodes would remain relatively distributed. Hence, block pruning is a feasible solution. However, in order to start pruning, one would have to have the full blockchain to begin with. As currently designed, downloading blockchain for the first time also audits previous blocks for accuracy, this can take days depending on one’s bandwidth. This online method is the only way to distribute the bitcoin blockchain and the bitcoin network so far. When the size of blockchain becomes a concern, a simpler distribution idea should be implemented offline. Consider distributions of Linux-based operating systems on USBs. Similarly, the full bitcoin blockchain up to a certain point can be distributed via easy-to-mail USBs. Note that even if we were to get the blockchain in bulk on such a USB, some form of a block audit would have to happen nevertheless. A new form of checkpoint hashes could be added to the bitcoin code. For instance, each 2016 blocks (whenever the difficulty readjusts), all IDs from previous 2015 blocks would be hashed and recorded. That way, with our particular offline blockchain distribution, the first time user would have to audit only the key 2016th blocks, designed to occur on average once in roughly 2 weeks. This would significantly reduce bandwidth concerns for the auditing process because only each 2016th block would have to be uploaded online to be audited. Overall, we are able to scale the bitcoin network via initial on-chain scaling approaches supplemented with off-chain scaling approaches. This upgrades the current network to a pruned peer-to-peer network with integrated 2L managed by miners and nodes who assure that the bitcoin network stays decentralized, distributed, immutable.
