It's a dead fork of Bitcoin, result of community unhappiness with where Bitcoin was going.
Either way, it's "maintained" by Bitmain (from their wallet at least) which is a non-alternative.
If you want electronic, peer to peer, private cash, Monero is the way to go.
There are at least three big lies in this post if we skip the bitmain statement:
  1. That Bitcoin Cash is a "dead fork" of Bitcion.
  2. That Bitcoin Cash is not usable as p2p, private (CashShuffle) digitial Cash.
  3. That Monero somehow is.
Monero of course is completely unusable in comparison to Bitcoin Cash. You have to wait at the very least 20 minutes after spending your funds before you're able to spend them again. I.e. if you send a submaximal amount of monero, you can't use the rest of your funds for twenty minutes!
Monero is also not any faster transactionally than BCH. Having a faster block time doesn't mean you're faster, it just means you're accepting less security per confirmation.
Not to mention that the Monero core wallet is nearly impossible to sync. Often you are told to use a "remote node", but this dramatically weakens your privacy. More so than the default weakness that comes with Monero's really small anon set, and the tracing attacks linked below.
  1. How buying pot with Monero will get you busted — Knacc attack on Cryptonote coins
  2. Exchange Denial of Service in Monero
  3. Fake deposit amount exchange vulnerability in Monero
  4. Hiding your IP while using Ryo or other Cryptonotes + IP reveal exploit in Monero/OpenAlias
  5. Cryptonight-GPU — FPGA-proof PoW algorithm based on floating point instructions
  6. Tracing Cryptonote ring signatures using external metadata
  7. Newly added - FloodXMR: Low-cost transaction flooding attack with Monero’s bulletproof protocol*
We show how an attacker can take advantage of Monero’s Bulletproof protocol, which reduces transaction fees, to flood the network with his own transactions and, consequently, remove mixins from transaction inputs.
Assuming an attack timeframe of 12 months, our findings show that an attacker can trace up to 47.63% of the transaction inputs at a cost of just 1,746.53 USD.1 Moreover, we show also that more than 90% of the inputs are affected by our tracing algorithm.
  1. That cost was based on transactions with 100 outputs, while the monero protocol limits this number to 16, which increases the cost of the attack to roughly $10,000 USD
A former developer for Monero stated that Monero's privacy doesn't work.
https://www.reddit.com/dashpay/comments/bindps/when_the_fud_finally_fails_and_the_ugly_hot_girl/em92sbz/
fireice_uk stated in his article, there's really no way to fix it.
I didn't say that. I think it can be fixed, however as is, Monero's (and all other cryptonotes') privacy is not fit for purpose.
So why are the Monero members lying about their utility w.r.t. to BCH as digital, private Cash? I think this would be a great discussion to have!

AMA with Sinovate, a new GPU friendly coin with new innovations to the space

SINOVATE
What SINOVATE is aiming on Cryptocurrency Market?
SINOVATE is created for Innovation and it aims to keep bringing never before seen Innovations in the crypto market.
What is Infinity Nodes, why different from Classical Masternode System? Infinity Nodes are groundbreaking evolved masternodes that solves the inflation problem. Traditional masternodes start with high ROI but with very large inflation and that inflation is what inevitably makes them fail.
What is IDS, why is it better than cloud storage? And size providers how to get/ earn SIN?
IDS = Incorruptible Data Storage.
IDS is a peer-to-peer private networking system, which will permit transactions and storage between miners and Infinity Node owners. Competitors including Sia, Storj, BitTorrent and even IPFS solutions reward individuals for serving and hosting content on their hard drive space, which requires a 24/7 uptime for computers. User hard drives must remain open and the rewards received must justify the costs incurred for leaving computer online.
In IDS, the private networking of decentralized storage relies solely on the SINOVATE Blockchain, with only node owners receiving rewards as compensation for utilising their hard drive resources to run an Infinity Node. Node owners will get rewards both from the Infinity Nodes and from storing confidential data.
IDS will have 5 steps of evolution.
SINOVATE has 533 tp/s. How are you planning to use this as a use case?
Scalability is one of the biggest problems in cryptocurrencies. POS only or centralized cryptocurrencies have higher scalability but are not suitable for the original Satoshi plan. Satoshi Nakamoto’s dream was everybody to mine their own coins without being centralized so SINOVATE blockchain not only is the most scalable POW cryptocurrency but will also have much more increased scalability in the future. Mass adoption requires high scalability especially when it will be used in real life as a payment means. Are we going to see SINOVATE Payment System in the future?
SINOVATE payment gateway will be released this year with high scalability and less than 3 seconds transaction times with the help of FlashSend.
What is SINOVATE aiming with X25X Algorithm?
SINOVATE formerly SUQA always aimed at the ordinary user starting with the X22i custom algorithm and upgraded to X25X to fight the big hardware companies so everyone can mine their own coin without letting ASIC,FPGA companies dominate the network.
Algo Comparison Chart
We are committed to remaining ASIC / FPGA resistant and such use an ever evolving algorithm, the latest variation named X25X launched with the last update. It is protected from difficulty attacks using Dark Gravity Wave v3 and raises the memory requirements compared to X22i bt a factor of five making it harder for ASIC / FPGA to implement.
What is Komodo dPOW , and when is the plan implementation on SINOVATE?
dPoW diagram
KOMODO DPoW is a working and trusted 51 % Attack protection technology to prevent any kind of malicious attacks by the help of notarized data of Bitcoin, KOMODO and SINOVATE chain.
What is the current status on mobile wallets? We saw a mobile wallet trailer.
Mobile wallets will be released in July 2019 as a custom good looking wallet tailored to the specific needs of SIN Blockchain
What is the plan for adoption in real life SINOVATE?
Our team draws from a large diversity of skills from many areas of business and across many different industries. This allows us to design and hone the experience of interacting with the SINOVATE Blockchain at many levels, from developers, business leaders and operational levels, down to the end-user experience.
This allows us to develop software and user experiences from the perspective of all involved, ensuring that the end user is the primary focus.
What is the current financial status on SINOVATE?
SINOVATE are transparent about the financial status of the foundation and the activity taken with funds. We regularly publish updates and the latest one for June is here.
What partnerships will there be in the future?
Besides the Masternodes related partnerships, SINOVATE partnered with KOMODO for the integration of dPoW 51% attack protection, which will be active at the end of July or early August 2019.
As the foundation’s mission is to grow the space for all. We are happy to work with all projects and businesses both by learning from the great work others have undertaken and offering something back to other projects with our open source code.
With Governance what can it do for the community?
Decentralized governance is the future of any successful blockchain project, SINOVATE believes that blockchain will be ubiquitous in the underlying infrastructure and services in the future of everyday life. Having fair voting for developments, marketing and innovations of the SINOVATE chain will be very important for everyone.

AMD's Growing CPU Advantage Over Intel

https://seekingalpha.com/article/4152240-amds-growing-cpu-advantage-intel?page=1
AMD's Growing CPU Advantage Over Intel Mar. 1.18 | About: Advanced Micro (AMD)
Raymond Caron, Ph.D. Tech, solar, natural resources, energy (315 followers) Summary AMD's past and economic hazards. AMD's Current market conditions. AMD Zen CPU advantage over Intel. AMD is primarily a CPU fabrication company with much experience and a great history in that respect. They hold patents for 64-bit processing, as well as ARM based processing patents, and GPU architecture patents. AMD built a name for itself in the mid-to-late 90’s when they introduced the K-series CPU’s to good reviews followed by the Athlon series in ‘99. AMD was profitable, they bought the companies NexGen, Alchemy Semiconductor, and ATI. Past Economic Hazards If AMD has such a great history, then what happened? Before I go over the technical advantage that AMD has over Intel, it’s worth looking to see how AMD failed in the past, and to see if those hazards still present a risk to AMD. As for investment purposes we’re more interested in AMD’s turning a profit. AMD suffered from intermittent CPU fabrication problems, and was also the victim of sustained anti-competitive behaviour from Intel who interfered with AMD’s attempts to sell its CPU’s to the market through Sony, Hitachi, Toshiba, Fujitsu, NEC, Dell, Gateway, HP, Acer, and Lenovo. Intel was investigated and/or fined by multiple countries including Japan, Korea, USA, and EU. These hazard needs to be examined to see if history will repeat itself. There have been some rather large changes in the market since then.
1) The EU has shown they are not averse to leveling large fines, and Intel is still fighting the guilty verdict from the last EU fine levied against them; they’ve already lost one appeal. It’s conceivable to expect that the EU, and other countries, would prosecute Intel again. This is compounded by the recent security problems with Intel CPU’s and the fact that Intel sold these CPU’s under false advertising as secure when Intel knew they were not. Here are some of the largest fines dished out by the EU
2) The Internet has evolved from Web 1.0 to 2.0. Consumers are increasing their online presence each year. This reduces the clout that Intel can wield over the market as AMD can more easily sell to consumers through smaller Internet based companies.
3) Traditional distributors (HP, Dell, Lenovo, etc.) are struggling. All of these companies have had recent issues with declining revenue due to Internet competition, and ARM competition. These companies are struggling for sales and this reduces the clout that Intel has over them, as Intel is no longer able to ensure their future. It no longer pays to be in the club. These points are summarized in the graph below, from Statista, which shows “ODM Direct” sales and “other sales” increasing their market share from 2009 to Q3 2017. 4) AMD spun off Global Foundries as a separate company. AMD has a fabrication agreement with Global Foundries, but is also free to fabricate at another foundry such as TSMC, where AMD has recently announced they will be printing Vega at 7nm.
5) Global Foundries developed the capability to fabricate at 16nm, 14nm, and 12nm alongside Samsung, and IBM, and bought the process from IBM to fabricate at 7nm. These three companies have been cooperating to develop new fabrication nodes.
6) The computer market has grown much larger since the mid-90’s – 2006 when AMD last had a significant tangible advantage over Intel, as computer sales rose steadily until 2011 before starting a slow decline, see Statista graph below. The decline corresponds directly to the loss of competition in the marketplace between AMD and Intel, when AMD released the Bulldozer CPU in 2011. Tablets also became available starting in 2010 and contributed to the fall in computer sales which started falling in 2012. It’s important to note that computer shipments did not fall in 2017, they remained static, and AMD’s GPU market share rose in Q4 2017 at the expense of Nvidia and Intel.
7) In terms of fabrication, AMD has access to 7nm on Global Foundries as well as through TSMC. It’s unlikely that AMD will experience CPU fabrication problems in the future. This is something of a reversal of fortunes as Intel is now experiencing issues with its 10nm fabrication facilities which are behind schedule by more than 2 years, and maybe longer. It would be costly for Intel to use another foundry to print their CPU’s due to the overhead that their current foundries have on their bottom line. If Intel is unable to get the 10nm process working, they’re going to have difficulty competing with AMD. AMD: Current market conditions In 2011 AMD released its Bulldozer line of CPU’s to poor reviews and was relegated to selling on the discount market where sales margins are low. Since that time AMD’s profits have been largely determined by the performance of its GPU and Semi-Custom business. Analysts have become accustomed to looking at AMD’s revenue from a GPU perspective, which isn’t currently being seen in a positive light due to the relation between AMD GPU’s and cryptocurrency mining.
The market views cryptocurrency as further risk to AMD. When Bitcoin was introduced it was also mined with GPU’s. When the currency switched to ASIC circuits (a basic inexpensive and simple circuit) for increased profitability (ASIC’s are cheaper because they’re simple), the GPU’s purchased for mining were resold on the market and ended up competing with and hurting new AMD GPU sales. There is also perceived risk to AMD from Nvidia which has favorable reviews for its Pascal GPU offerings. While AMD has been selling GPU’s they haven’t increased GPU supply due to cryptocurrency demand, while Nvidia has. This resulted in a very high cost for AMD GPU’s relative to Nvidia’s. There are strategic reasons for AMD’s current position:
1) While the AMD GPU’s are profitable and greatly desired for cryptocurrency mining, AMD’s market access is through 3rd party resellers whom enjoy the revenue from marked-up GPU sales. AMD most likely makes lower margins on GPU sales relative to the Zen CPU sales due to higher fabrication costs associated with the fabrication of larger size dies and the corresponding lower yield. For reference I’ve included the size of AMD’s and Nvidia’s GPU’s as well as AMD’s Ryzen CPU and Intel’s Coffee lake 8th generation CPU. This suggests that if AMD had to pick and choose between products, they’d focus on Zen due higher yield and revenue from sales and an increase in margin.
2) If AMD maintained historical levels of GPU production in the face of cryptocurrency demand, while increasing production for Zen products, they would maximize potential income for highest margin products (EPYC), while reducing future vulnerability to second-hand GPU sales being resold on the market. 3) AMD was burned in the past from second hand GPU’s and want to avoid repeating that experience. AMD stated several times that the cryptocurrency boom was not factored into forward looking statements, meaning they haven’t produced more GPU’s to expect more GPU sales.
In contrast, Nvidia increased its production of GPU’s due to cryptocurrency demand, as AMD did in the past. Since their Pascal GPU has entered its 2nd year on the market and is capable of running video games for years to come (1080p and 4k gaming), Nvidia will be entering a position where they will be competing directly with older GPU’s used for mining, that are as capable as the cards Nvidia is currently selling. Second-hand GPU’s from mining are known to function very well, with only a need to replace the fan. This is because semiconductors work best in a steady state, as opposed to being turned on and off, so it will endure less wear when used 24/7.
The market is also pessimistic regarding AMD’s P/E ratio. The market is accustomed to evaluating stocks using the P/E ratio. This statistical test is not actually accurate in evaluating new companies, or companies going into or coming out of bankruptcy. It is more accurate in evaluating companies that have a consistent business operating trend over time.
“Similarly, a company with very low earnings now may command a very high P/E ratio even though it isn’t necessarily overvalued. The company may have just IPO’d and growth expectations are very high, or expectations remain high since the company dominates the technology in its space.” P/E Ratio: Problems With The P/E I regard the pessimism surrounding AMD stock due to GPU’s and past history as a positive trait, because the threat is minor. While AMD is experiencing competitive problems with its GPU’s in gaming AMD holds an advantage in Blockchain processing which stands to be a larger and more lucrative market. I also believe that AMD’s progress with Zen, particularly with EPYC and the recent Meltdown related security and performance issues with all Intel CPU offerings far outweigh any GPU turbulence. This turns the pessimism surrounding AMD regarding its GPU’s into a stock benefit. 1) A pessimistic group prevents the stock from becoming a bubble. -It provides a counter argument against hype relating to product launches that are not proven by earnings. Which is unfortunately a historical trend for AMD as they have had difficulty selling server CPU’s, and consumer CPU’s in the past due to market interference by Intel. 2) It creates predictable daily, weekly, monthly, quarterly fluctuations in the stock price that can be used, to generate income. 3) Due to recent product launches and market conditions (Zen architecture advantage, 12nm node launching, Meltdown performance flaw affecting all Intel CPU’s, Intel’s problems with 10nm) and the fact that AMD is once again selling a competitive product, AMD is making more money each quarter. Therefore the base price of AMD’s stock will rise with earnings, as we’re seeing. This is also a form of investment security, where perceived losses are returned over time, due to a stock that is in a long-term upward trajectory due to new products reaching a responsive market.
4) AMD remains a cheap stock. While it’s volatile it’s stuck in a long-term upward trend due to market conditions and new product launches. An investor can buy more stock (with a limited budget) to maximize earnings. This is advantage also means that the stock is more easily manipulated, as seen during the Q3 2017 ER.
5) The pessimism is unfounded. The cryptocurrency craze hasn’t died, it increased – fell – and recovered. The second hand market did not see an influx of mining GPU’s as mining remains profitable.
6) Blockchain is an emerging market, that will eclipse the gaming market in size due to the wide breath of applications across various industries. Vega is a highly desired product for Blockchain applications as AMD has retained a processing and performance advantage over Nvidia. There are more and rapidly growing applications for Blockchain every day, all (or most) of which will require GPU’s. For instance Microsoft, The Golem supercomputer, IBM, HP, Oracle, Red Hat, and others. Long-term upwards trend AMD is at the beginning of a long-term upward trend supported by a comprehensive and competitive product portfolio that is still being delivered to the market, AMD referred to this as product ramping. AMD’s most effective products with Zen is EPYC, and the Raven Ridge APU. EPYC entered the market in mid-December and was completely sold out by mid-January, but has since been restocked. Intel remains uncompetitive in that industry as their CPU offerings are retarded by a 40% performance flaw due to Meltdown patches. Server CPU sales command the highest margins for both Intel and AMD.
The AMD Raven Ridge APU was recently released to excellent reviews. The APU is significant due to high GPU prices driven buy cryptocurrency, and the fact that the APU is a CPU/GPU hybrid which has the performance to play games available today at 1080p. The APU also supports the Vulcan API, which can call upon multiple GPU’s to increase performance, so a system can be upgraded with an AMD or Nvidia GPU that supports Vulcan API at a later date for increased performance for those games or workloads that been programmed to support it. Or the APU can be replaced when the prices of GPU’s fall.
AMD also stands to benefit as Intel confirmed that their new 10 nm fabrication node is behind in technical capability relative to the Samsung, TSMC, and Global Foundries 7 nm fabrication process. This brings into questions Intel’s competitiveness in 2019 and beyond. Take-Away • AMD was uncompetitive with respect to CPU’s from 2011 to 2017 • When AMD was competitive, from 1996 to 2011 they did record profit and bought 3 companies including ATI. • AMD CPU business suffered from: • Market manipulation from Intel. • Intel fined by EU, Japan, Korea, and settled with the USA • Foundry productivity and upgrade complications • AMD has changed • Global Foundries spun off as an independent business • Has developed 14nm &12nm, and is implementing 7nm fabrication • Intel late on 10nm, is less competitive than 7nm node • AMD to fabricate products using multiple foundries (TSMC, Global Foundries) • The market has changed • More AMD products are available on the Internet and both the adoption of the Internet and the size of the Internet retail market has exploded, thanks to the success of smartphones and tablets. • Consumer habits have changed, more people shop online each year. Traditional retailers have lost market share. • Computer market is larger (on-average), but has been declining. While Computer shipments declined in Q2 and Q3 2017, AMD sold more CPU’s. • AMD was uncompetitive with respect to CPU’s from 2011 to 2017. • Analysts look to GPU and Semi-Custom sales for revenue. • Cryptocurrency boom intensified, no crash occurred. • AMD did not increase GPU production to meet cryptocurrency demand. • Blockchain represents a new growth potential for AMD GPU’s. • Pessimism acts as security against a stock bubble & corresponding bust. • Creates cyclical volatility in the stock that can be used to generate profit. • P/E ratio is misleading when used to evaluate AMD. • AMD has long-term growth potential. • 2017 AMD releases competitive product portfolio. • Since Zen was released in March 2017 AMD has beat ER expectations. • AMD returns to profitability in 2017. • AMD taking measureable market share from Intel in OEM CPU Desktop and in CPU market. • High margin server product EPYC released in December 2017 before worst ever CPU security bug found in Intel CPU’s that are hit with detrimental 40% performance patch. • Ryzen APU (Raven Ridge) announced in February 2018, to meet gaming GPU shortage created by high GPU demand for cryptocurrency mining. • Blockchain is a long-term growth opportunity for AMD. • Intel is behind the competition for the next CPU fabrication node. AMD’s growing CPU advantage over Intel About AMD’s Zen Zen is a technical breakthrough in CPU architecture because it’s a modular design and because it is a small CPU while providing similar or better performance than the Intel competition.
Since Zen was released in March 2017, we’ve seen AMD go from 18% CPU market share in the OEM consumer desktops to essentially 50% market share, this was also supported by comments from Lisa Su during the Q3 2017 ER call, by MindFactory.de, and by Amazon sales of CPU’s. We also saw AMD increase its market share of total desktop CPU’s. We also started seeing market share flux between AMD and Intel as new CPU’s are released. Zen is a technical breakthrough supported by a few general guidelines relating to electronics. This provides AMD with an across the board CPU market advantage over Intel for every CPU market addressed.
1) The larger the CPU the lower the yield. - Zen architecture that makes up Ryzen, Threadripper, and EPYC is smaller (44 mm2 compared to 151 mm2 for Coffee Lake). A larger CPU means fewer CPU’s made during fabrication per wafer. AMD will have roughly 3x the fabrication yield for each Zen printed compared to each Coffee Lake printed, therefore each CPU has a much lower cost of manufacturing.
2) The larger the CPU the harder it is to fabricate without errors. - The chance that a CPU will be perfectly fabricated falls exponentially with increasing surface area. Intel will have fewer high quality CPU’s printed compared to AMD. This means that AMD will make a higher margin on each CPU sold. AMD’s supply of perfect printed Ryzen’s (1800X) are so high that the company had to give them away at a reduced cost in order to meet supply demands for the cheaper Ryzen 5 1600X. If you bought a 1600X in August/September, you probably ended up with an 1800X.
3) Larger CPU’s are harder to fabricate without errors on smaller nodes. -The technical capability to fabricate CPU’s at smaller nodes becomes more difficult due to the higher precision that is required to fabricate at a smaller node, and due to the corresponding increase in errors. “A second reason for the slowdown is that it’s simply getting harder to design, inspect and test chips at advanced nodes. Physical effects such as heat, electrostatic discharge and electromagnetic interference are more pronounced at 7nm than at 28nm. It also takes more power to drive signals through skinny wires, and circuits are more sensitive to test and inspection, as well as to thermal migration across a chip. All of that needs to be accounted for and simulated using multi-physics simulation, emulation and prototyping.“ Is 7nm The Last Major Node? “Simply put, the first generation of 10nm requires small processors to ensure high yields. Intel seems to be putting the smaller die sizes (i.e. anything under 15W for a laptop) into the 10nm Cannon Lake bucket, while the larger 35W+ chips will be on 14++ Coffee Lake, a tried and tested sub-node for larger CPUs. While the desktop sits on 14++ for a bit longer, it gives time for Intel to further develop their 10nm fabrication abilities, leading to their 10+ process for larger chips by working their other large chip segments (FPGA, MIC) first.” There are plenty of steps where errors can be created within a fabricated CPU. This is most likely the culprit behind Intel’s inability to launch its 10nm fabrication process. They’re simply unable to print such a large CPU on such a small node with high enough yields to make the process competitive. Intel thought they were ahead of the competition with respect to printing large CPU’s on a small node, until AMD avoided the issue completely by designing a smaller modular CPU. Intel avoided any mention of its 10nm node during its Q4 2017 ER, which I interpret as bad news for Intel shareholders. If you have nothing good to say, then you don’t say anything. Intel having nothing to say about something that is fundamentally critical to its success as a company can’t be good. Intel is on track however to deliver hybrid CPU’s where some small components are printed on 10nm. It’s recently also come to light that Intel’s 10nm node is less competitive than the Global Foundries, Samsung, and TSMC 7nm nodes, which means that Intel is now firmly behind in CPU fabrication. 4) AMD Zen is a new architecture built from the ground up. Intel’s CPU’s are built on-top of older architecture developed with 30-yr old strategies, some of which we’ve recently discovered are flawed. This resulted in the Meltdown flaw, the Spectre flaws, and also includes the ME, and AMT bugs in Intel CPU’s. While AMD is still affected by Spectre, AMD has only ever acknowledged that they’re completely susceptible to Spectre 1, as AMD considers Spectre 2 to be difficult to exploit on an AMD Zen CPU. “It is much more difficult on all AMD CPUs, because BTB entries are not aliased - the attacker must know (and be able to execute arbitrary code at) the exact address of the targeted branch instruction.” Technical Analysis of Spectre & Meltdown * Amd Further reading Spectre and Meltdown: Linux creator Linus Torvalds criticises Intel's 'garbage' patches | ZDNet FYI: Processor bugs are everywhere - just ask Intel and AMD Meltdown and Spectre: Good news for AMD users, (more) bad news for Intel Cybersecurity agency: The only sure defense against huge chip flaw is a new chip Kernel-memory-leaking Intel processor design flaw forces Linux, Windows redesign Take-Away • AMD Zen enjoys a CPU fabrication yield advantage over Intel • AMD Zen enjoys higher yield of high quality CPU’s • Intel’s CPU’s are affected with 40% performance drop due to Meltdown flaw that affect server CPU sales.

4) Mobile Ryzen APU sales • -Providing gaming capability in a compact power envelope.
5) Ryzen and Threadripper sales • -Fabricated on 12nm in April. • -May eliminate Intel’s last remaining CPU advantage in IPC single core processing. • -AM4 motherboard supported until 2020. • -7nm Ryzen on track for early 2019. 6) Others: Vega, Polaris, Semi-custom, etc. • -I consider any positive developments here to be gravy. Conclusion While in the past Intel interfered with AMD's ability to bring it's products to market, the market has changed. The internet has grown significantly and is now a large market that dominates when in computer sales. It's questionable if Intel still has the influence to affect this new market, and doing so would most certainly result in fines and further bad press.
AMD's foundry problems were turned into an advantage over Intel.
AMD's more recent past was heavily influenced by the failure of the Bulldozer line of CPU's that dragged on AMD's bottom line from 2011 to 2017.
AMD's Zen line of CPU's is a breakthrough that exploits an alternative, superior strategy, in chip design which results in a smaller CPU. A smaller CPU enjoys compounded yield and quality advantages over Intel's CPU architecture. Intel's lead in CPU performance will at the very least be challenged and will more likely come to an end in 2018, until they release a redesigned CPU.
I previously targeted AMD to be worth $20 by the end of Q4 2017 ER. This was based on the speed that Intel was able to get products to market, in comparison AMD is much slower. I believe the stock should be there, but the GPU related story was prominent due to cryptocurrency craze. Financial analysts need more time to catch on to what’s happening with AMD, they need an ER that is driven by CPU sales. I believe that the Q1 2018 is the ER to do that. AMD had EPYC stock in stores when the Meltdown and Spectre flaws hit the news. These CPU’s were sold out by mid-January and are large margin sales.
There are many variables at play within the market, however barring any disruptions I’d expect that AMD will be worth $20 at some point in 2018 due these market drivers. If AMD sold enough EPYC CPU’s due to Intel’s ongoing CPU security problems, then it may occur following the ER in Q1 2018. However, if anything is customary with AMD, it’s that these things always take longer than expected.

What is Bitcoin?
Bitcoin is an experimental system of transfer and verification of property based on a network of peer to peer without any central authority.
The initial application and the main innovation of the Bitcoin network is a system of digital currency decentralized unit of account is bitcoin.
Bitcoin works with software and a protocol that allows participants to issue bitcoins and manage transactions in a collective and automatic way. As a free Protocol (open source), it also allows interoperability of software and services that use it. As a currency bitcoin is both a medium of payment and a store of value.
Bitcoin is designed to self-regulate. The limited inflation of the Bitcoin system is distributed homogeneously by computing the network power, and will be limited to 21 million divisible units up to the eighth decimal place. The functioning of the Exchange is secured by a general organization that everyone can examine, because everything is public: the basic protocols, cryptographic algorithms, programs making them operational, the data of accounts and discussions of the developers.
The possession of bitcoins is materialized by a sequence of numbers and letters that make up a virtual key allowing the expenditure of bitcoins associated with him on the registry. A person may hold several key compiled in a 'Bitcoin Wallet ', 'Keychain' web, software or hardware which allows access to the network in order to make transactions. Key to check the balance in bitcoins and public keys to receive payments. It contains also (often encrypted way) the private key associated with the public key. These private keys must remain secret, because their owner can spend bitcoins associated with them on the register. All support (keyrings) agrees to maintain the sequence of symbols constituting your keychain: paper, USB, memory stick, etc. With appropriate software, you can manage your assets on your computer or your phone.
Bitcoin on an account, to either a holder of bitcoins in has given you, for example in Exchange for property, either go through an Exchange platform that converts conventional currencies in bitcoins, is earned by participating in the operations of collective control of the currency.
The sources of Bitcoin codes have been released under an open source license MIT which allows to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software, subject to insert a copyright notice into all copies.
Bitcoin creator, Satoshi Nakamoto
What is the Mining of bitcoin?
Technical details :
During mining, your computer performs cryptographic hashes (two successive SHA256) on what is called a header block. For each new hash, mining software uses a different random number that called Nuncio. According to the content of the block and the nonce value typically used to express the current target. This number is called the difficulty of mining. The difficulty of mining is calculated by comparing how much it is difficult to generate a block compared to the first created block. This means that a difficulty of 70000 is 70000 times more effort that it took to Satoshi Nakamoto to generate the first block. Where mining was much slower and poorly optimized.
The difficulty changes each 2016 blocks. The network tries to assign the difficulty in such a way that global computing power takes exactly 14 days to generate 2016 blocks. That's why the difficulty increases along with the power of the network.
Material :
In the beginning, mining with a processor (CPU) was the only way to undermine bitcoins. (GPU) graphics cards have possibly replaced the CPU due to their nature, which allowed an increase between 50 x to 100 x in computing power by using less electricity by megahash compared to a CPU.
Although any modern GPU can be used to make the mining, the brand AMD GPU architecture has proved to be far superior to nVidia to undermine bitcoins and the ATI Radeon HD 5870 card was the most economical for a time.
For a more complete list of graphics cards and their performance, see Wiki Bitcoin: comparison of mining equipment
In the same way that transition CPU to GPU, the world of mining has evolved into the use of the Field Programmable Gate Arrays (FPGA) as a mining platform. Although FPGAs did not offer an increase of 50 x to 100 x speed of calculation as the transition from CPU to GPU, they offered a better energy efficiency.
A typical HD/s 600 graphics card consumes about 400w of power, while a typical FPGA device can offer a rate of hash of 826 MH/s to 80w of power consumption, a gain of 5 x more calculations for the same energy power. Since energy efficiency is a key factor in the profitability of mining, it was an important step for the GPU to FPGA migration for many people.
The world of the mining of bitcoin is now migrating to the Application Specific Integrated Circuit (ASIC). An ASIC is a chip designed specifically to accomplish a single task. Unlike FPGAs, an ASIC is unable to be reprogrammed for other tasks. An ASIC designed to undermine bitcoins cannot and will not do anything else than to undermine bitcoins.
The stiffness of an ASIC allows us to offer an increase of 100 x computing power while reducing power consumption compared to all other technologies. For example, a classic device to offer 60 GH/s (1 hashes equals 1000 Megahash. 1GH/s = 1000 Mh/s) while consuming 60w of electricity. Compared to the GPU, it is an increase in computing power of 100 x and a reduction of power consumption by a factor of 7.
Unlike the generations of technologies that have preceded the ASIC, ASIC is the "end of the line" when we talk about important technology change. The CPUs have been replaced by the GPUs, themselves replaced by FPGAs that were replaced by ASICs.
There is nothing that can replace the ASICs now or in the immediate future. There will be technological refinements in ASIC products, and improvements in energy efficiency, but nothing that may match increased from 50 x to 100 x the computing power or a 7 x reduction in power consumption compared with the previous technology.
Which means that the energy efficiency of an ASIC device is the only important factor of all product ASIC, since the estimated lifetime of an ASIC device is superior to the entire history of the mining of bitcoin. It is conceivable that a purchased ASIC device today is still in operation in two years if the unit still offers a profitable enough economic to keep power consumption. The profitability of mining is also determined by the value of bitcoin but in all cases, more a device has a good energy efficiency, it is profitable.
Software :
There are two ways to make mining: by yourself or as part of a team (a pool). If you are mining for yourself, you must install the Bitcoin software and configure it to JSON-RPC (see: run Bitcoin). The other option is to join a pool. There are multiple available pools. With a pool, the profit generated by any block generated by a member of the team is split between all members of the team. The advantage of joining a team is to increase the frequency and stability of earnings (this is called reduce the variance) but gains will be lower. In the end, you will earn the same amount with the two approaches. Undermine solo allows you to receive earnings huge but very infrequent, while miner with a pool can offer you small stable and steady gains.
Once you have your software configured or that you have joined a pool, the next step is to configure the mining software. The software the most populare for ASIC/FPGA/GPU currently is CGminer or a derivative designed specifically for FPGAS and ASICs, BFGMiner.
If you want a quick overview of mining without install any software, try Bitcoin Plus, a Bitcoin minor running in your browser with your CPU. It is not profitable to make serious mining, but it is a good demonstration of the principle of the mining team.

Will I earn money by mining? - An answer to all newcomers

When people start their adventure with Bitcoin, they often go through a small gold fever with the concept of mining (I would know, that's how I started ;) ). Here is a small guide to answer your eternal question "will I make money with it?":
First of all, lets talk about hardware (click on the link for a long and useful list). You won't make money mining bitcoins unless you either have a really high-end GPU from ATI, an FPGA or an ASIC. That's the short answer. Having a decent CPU can be used for Litecoin mining, which can be a small income in itself, but we are here to talk about Bitcoin.
To see whether you will earn any money, you need to input a few pieces of data into a special calculator:
And then there are two magical variables that will either make it all work out, or be doomed for failure: * difficulty - it is automatically filled in by the calculator, but for long-term mining (more than a few weeks), you want to be a pessimist. Multiply the value by 10 for predictions over a few months or 100 for a year or two (it will rise steeply soon) * bitcoin price - also filled by the calculator - it might go up or down in the future, affecting your bottom line. It will probably increase in the long run, but lets be pessimistic and lower that to $10-$20 to make sure we are earning money no matter what
Having all your hard data and your guesses on the last two variables, you put it all into the mining calculator and see what you get. You will get your earnings in BTC and dollars, as well as summary of your costs and when you will brake even, and what will your net income be over your investment period.
Most likely you won't be earning money with Bitcoin mining, and that's okay - mining has become a very specialised process. If you want to invest money into new ASICs, you might be able to turn a tidy profit.
TLDR: Use this to check everything. ASICs may earn you money, GPUs won't anymore.

VNT Chain AMA - July 14

VNT Chain AMA - July 14
Welcome to the community of VNT Chain! We are the VNT Team and excited to announce that we are going to do monthly (or more often) AMA (Ask Me Anything) to listen and speak to our community members directly, on any topic! Each AMA will have its own main topic but any valuable topic or question not answered in the current AMA will be transferred to the next one.
We already had our first AMA on all our WeChat groups and Telegram channels, on July 14. Here’s a summary of the first AMA event.
VNT Chain Introduction
Powered by the worldwide leading blockchain service provider--Yunphant, VNT Chain is dedicated to build a global distributed smart value network, to provide efficient, friendly and low-cost services in finance, healthcare, supply chain, gaming etc.
Speaker Introduction
Dr. Huang Butian, co-founder of VNT Chain and founder of Yunphant Blockchain, founder of Blockchain Special Committee of China Computer Federation, got his PhD degree from Zhejiang University in Computer Science. Dr. Huang has raised more than 40 blockchain-related patent applications, ranked ninth in the global blockchain patents by 2017. He’s also the author of the book “Blockchain decryption – To build the next generation of internet based on trust”.
Q1:@Mo (Group 9) Please give us a brief introduction to the VNT Chain team.
A:
VNT Chain is powered by Yunphant. Yunphant was founded in 2014. It’s a senior member of hyperledger, focusing on blockchain service and product innovation. Yunphant has broad industry experience and use cases in blockchain infrastructure and services, is the first cross agency blockchain service provider of Chinese commercial banks, and the only one blockchain service provider for the key research program in the modern service industry of the Ministry of Science and Technology, China.
The team has made the below key achievements so far.
  1. In the 2016 ASC World Supercomputer Competition, team members received the highest computing performance award.
  2. The team has applied for more than 40 invention patents, placed No.9 on the global blockchain patents ranking as of 2017 and placed No.1 on the global blockchain patent innovation talents ranking.
  3. The team has won the second of the 2017 Lee Kuan Yew Global Business Competition Finals.
  4. On June 7, 2018, at the "15th Zhejiang Merchants (Investment and Financing) Conference and 2018 Digital Economy Summit", Yunphant Blockchain won “2018 Zhejiang Merchants Pre-Unicorn” Award issued by the independent evaluation of "Zheshang" Magazine.
  5. On June 9, 2018, Yunphant Blockchain was selected into the "2018 Hurun Blockchain Enterprise List" - the leading company Top20.
  6. Yunphant Blockchain had two case studies elaborated in the 2018 China Blockchain Industry White Paper which was released by the Information Center of the Ministry of Industry and Information Technology: The Industrial Bank blockchain anti-counterfeiting platform and Minsheng Bank's blockchain-based domestic credit certificate project.
The Yunphant Blockchain has established cooperative relationships with research institutions such as Zhejiang University, National University of Singapore, Shandong University, and Zhejiang Gongshang University in the fields of smart contracts, consensus algorithms, virtual machines, zero-knowledge proof, lightning networks, etc.
Q2:@此心光明(Group 9):The VNT Consortium Chain+ Public Chain solution is in fact goes against the decentralization of the blockchain in public opinions. How can VNT guarantee sufficient decentralization?
A:
The more appropriate way to express “decentralization” is “non-centralization”. Please refer the article “Blockchain: Building a Credit-Based Next Generation Internet”. The issue that blockchain solves is the problem of trust. It is meaningless to implement completed decentralization in some application scenarios. What we should concern about is the performance, security, and scalability of blockchain, so that it can better connect with the real economy, generating greater commercial value. VNT supports the scalability mainly by reducing participation in consensus groups, improving the efficiency of consensus algorithms and combining the technologies of consortium chain and side chain.
Q3: @琥珀川(Group 3):What are the advantages of Vortex's consensus mechanism? How to achieve TPS above 10,000? How does VNT improve the speed of the public chain without losing the level of consensus?
A:
The traditional Bitcoin and Ethereum are mainly based on POW, which reaches a consensus based on the workload of miners. But the biggest problem is the low efficiency. From the technical level, first, the optimization of consensus algorithms. A lot of optimizations have been made to the traditional PBFT. The transaction and consensus optimization are processed in 2 channels. The consensus message is processed first, and Replica cancels the whole network broadcast of the transaction, improving the consensus response speed and reducing the demand for network bandwidth.
Another strategy is hardware acceleration. All the super nodes need to build their own servers, which calls for cost in a certain server, and equip each node with the GPU to make hardware acceleration for the verification that involved in the consensus algorithm.
In the future, we will implement a system operation framework of consensus verification through FPGA to perform point-to-point connection by implementing TCP/IP protocol, and to use ARP, ICMP, DHCP-assisted TCP/IP protocol to interact with other FPGA nodes, shortening the TCP/IP stack and making the FPGA In the real network; At the same time, the data message is converted into a message format that satisfies the requirements of the consensus protocol, and then be transmitted and broadcasted. Other FPGA nodes will send the votes and feedbacks when they receive messages. This kind of technology can greatly improve the communication efficiency, especially for intensive computing services.
Q4: @金元宝(Group 8)As the pioneer of the financial application of blockchain technology both domestically and internationally, how do you think of the comparison between VNT and Ripple which is recently put forward by media agencies?
A:
It is true that Yunphant and Ripple are doing something similar. Ripple provides a global financial settlement solution that is dedicated to promoting the standard trading protocol common to all major banks around the world, replacing the swift network. Yunphant provides blockchain infrastructure services to establish distributed shared ledgers for commercial banks. At present, the credit certificate information and the electronic transmission system of trading documents based on blockchain technology have been constructed, which reduces the time of credit certificate transaction from 3-5 days to seconds. It can improve the acceptance efficiency of the credit certificate business and eliminate the cost of offline certification. Logistics, taxation, and the like can be incorporated in following up processes, solving the authenticity problems of trade background for banks.
Q5: 桐博博 (Group 10):The improvement of the blockchain is to improve the security of the system and reduce the operating cost of enterprises. The essence of the VNT Chain is the integration of the consortium chain and the public chain, which calls for a great amount of workload. However, the quantity standard on the public chain of every consortium chain may differ, and it will be a waste of resources of the public chain. And at the same time different standards can bring difficulties in code auditing, and it is more prone to security problems. My question is when it comes to the date docking on the public chain, can Dr. Huang provide any solutions?
A:
Well it’s a quite long question. Based on my understanding, you are asking what are the difficulties in implementation of “Public Chain+ Consortium Chain”?
https://preview.redd.it/bzlunw4fi7d11.png?width=452&format=png&auto=webp&s=2e1e19d6b9f477e84d1161d7f945471643d1f2c7
https://preview.redd.it/6q87egili7d11.png?width=1500&format=png&auto=webp&s=78c5fd072f2f493ae2cc1be36c084673639d6521
Note: 1. Ordinary contract will need to transfer data across the chain to the cross-chain contract; 2 Cross-chain nodes get cross-chain blocks from the cross-chain contract through rpc request; 3 Collect the block submitted to the verifier for verification; 4 Collect the block after submitting to the supervisor, and the certifier's behavior is supervised; 5 After the verification, the new block will be generated. 6 Side chain application transfers the cross-chain data.
It is indeed the technical integration of the consortium chain and the public chain, and the consistency of the data standards between consortium chains must be standardized. We are working with some banking institutions and trying to establish standards for financial district management of the commercial banking system.
The entire architecture involves a cross-chain mechanism, which is a technical difficulty for our current infrastructure. Here we have to resolve a cross-chain mechanism between the consortium chains, and the consortium chain and the public chain.
Q6: @Winter-tale (Group 5): According to my understanding, VNT Chain is to trade the assets or data on the consortium chain and then connect to the public chain through the cross-chain mechanism to realize the sale and purchase, which simply put is that to sell the assets or data of the organization to the c-end users? So my question is, will the assets and data of the organization be sold? Is one of the values ​​of VNT tokens used as a medium for buying or selling these assets or data?
A:
https://preview.redd.it/4d88u73ti7d11.png?width=553&format=png&auto=webp&s=89e993d773cccf0dc040b9fa5c7342612a3de9c2
VNT builds the exchange connector of data and asset. It is the infrastructure pipelines VNT Chain provide for the data and asset transactions among participating organizations. Therefore, VNT Token is not a medium for buying or selling data and asset, but a fuel GAS for trading contracts.
Q7:@爱嘻嘻(Group 3) What is the role of VNT tokens in the entire ecology? What is the economic incentive model for all parties including developers, miners, and investors?
A:
Incentives: Use VNT tokens to motivate community developers and contributing users;
Publish the app: Any individual or organization needs to pay VNT tokens to publish a decentralized application or smart contract on the VNT Chain network;
Circulating digital assets: Any user needs to pay VNT tokens to transfer assets on VNT Chain;
Consensus Reward: The Consensus Node can get VNT tokens from each transaction as a reward.
Q8:@山的那边(Group 10): Speaking of the financial sector, can you give an example of what kind of pain points does the VNT Chain solve? What kind of ecosystem will VNT Chain build in the future?
A:
This team “Designer” was hatched by us. The biggest problem in the financial sector is trust. VNT Chain hopes to build a global distributed smart value network to replace the traditional SWIFT network. At present, Yunphant Blockchain is cooperating with Minsheng Bank, China CITIC Bank, Suning Bank, Bank of China, etc. It is hoped that such a blockchain infrastructure will be built to lower the cost of credit certificate and improve the efficiency.
Despite of building infrastructure, VNT's ecosystem includes the establishment of a smart contract service platform (recently our incubation team Designer won the first place in the Thunder Global Blockchain Competition), the development of digital asset wallets, and game social networking. In addition, we have established joint research plans with Zhejiang University, National University of Singapore, Shandong University, Wuhan University and other universities to reserve the frontier technology research results of the blockchain. We will provide the greatest possibilities for the improvement of blockchain infrastructure! We are all working hard on the infrastructure construction and improvement of blockchain industry!
Q9: @funny (Group 1) Does the VNT under construct has a detailed plan for program implementation and application?
A:
We have completed the development of consortium chain, and we are now focusing on the development of the main chain and supplementary wallet, smart contract service platform, etc. In terms of program application, we are now gradually promoting the application of credit certificate and forfeiting for domestic commercial banks, and cooperating with some commercial organizations to promote the application of supply chain finance, and advancing some other business cooperation with local game manufactures in Hangzhou.
Q10: @Mo (Hangzhou): How does VNT think of the development and future of the global public chain, and what advantages does VNT have in current cooling-down market?
A:
I personally think that it the most advantageous technology should be the fusion of the consortium chain and the public chain. The synergy between on-chain and off- chain is an inevitable trend of management of infrastructure development in the future. Based on this, VNT is the first in the world to propose a fusion architecture of consortium chain + cross chain+ public chain, optimizing hardware acceleration through consensus algorithms to improve the performance of the main chain and supporting high scalability through consortium chain strategies. Through an architecture like this, the application problem of basic infrastructure can be solved. In addition, we have greater possibilities by the support from Yunphant Blockchain, especially the technology accumulation and application experiences.

Bitcoin mining evolves from GPU to FPGA and now custom ASIC

Bitcoin mining used to be rows of consumer gpu's brute-forcing the sha-256 encryption (max 2000 Mhash/s). After that people and companies started using expensive fpga setups to do it faster (100-25000 Mhash/s). Now companies have developed custom ASIC for bitcoin mining. (Avalon , Bitforce , Deepbit). It has an impressive speed of 4.5K -> 1500K Mhash/s . This increase of computing ability will probably put the gpu mining out of business and shake up the market abit.

Será que vou ganhar dinheiro com mineração? – Uma reposta para novatos em Bitcoin

Quando as pessoas começam a se aventurar com o Bitcoin, elas geralmente entram numa pequena “febre do ouro” com o conceito de mineração (Eu sei bem como é, eu comecei assim ;) ). Aqui daremos um pequeno guia para responder à eterna pergunta: “eu farei dinheiro com isso?”.
Em primeiro lugar, vamos falar sobre hardware [https://en.bitcoin.it/wiki/Mining_hardware_comparison] (clique no link para uma longa e útil lista). Você não irá fazer dinheiro minerando bitcoins a não ser que você tenha uma GPU da ATI, FPGA ou ASIC. Esta é uma resposta curta. Tendo uma CPU decente você pode minerar Litecoin [htpp://litecoin.org/], que pode ser uma pequena fonte de renda, mas nós estamos aqui para falar sobre Bitcoin.
Para ver se você vai ganhar algum dinheiro, você precisa colocar algumas pequenas informações numa calculadora especial [http://tpbitcalc.appspot.com/]:
E então existem duas variáveis mágicas que vão ou fazer tudo funcionar perfeitamente, ou condenar tudo ao fracasso: dificuldade – isto é automaticamente preenchido pela calculadora, mas para mineração por longos períodos (mais do que algumas semanas), você deve ser pessimista. Multiplique o valor por 10 para previsões acima de alguns meses ou 100 por um ano ou dois (isso vai subir em breve) *preço do bitcoin – também automaticamente preenchido pela calculadora – ele pode subir ou descer no futuro, afetando seu resultado final. Ele provavelmente subirá a longo tempo, mas vamos ser pessimistas e baixar esse preço para US$10-20 para ter certeza de que ganhemos dinheiro não importa o que aconteça.
Dedique todo o seu espaço de disco e palpites nessas duas variáveis, coloque tudo isso na calculadora de mineração e veja no que dá. Você terá seus ganhos em BTC e dólares, bem como um resumo de seus custos e ainda quando você pode ficar sem dinheiro, e qual será seu lucro líquido depois de seu período de investimento. O mais provável é que você não irá conseguir fazer dinheiro com mineração, e está tudo bem – mineração se tornou um processo bastante especializado. Se você quiser investir seu dinheiro em um novo ASIC, você pode ser capaz de conseguir de obter um lucro considerável.
Um resumo rápido para os preguiçosos: Use isso [http://tpbitcalc.appspot.com/] para verificar tudo. ASICs merecem o investimento de seu dinheiro, GPUs não.
