MultiMiner: Bitcoin Mining" align="left" /><p>Stratum: the server gives the client templates that the client can use to generate its own work. Only the block header and first transaction (generation transaction) are included. Stratum uses the least bandwidth of all the protocols. Stratum also makes it very fast and efficient to switch to new work data when there is a block change, which can help keep down the reject ratio caused by stale work. Unlike the other protocols it is not HTTP, so it won't work over an HTTP proxy. There is no real specification. There is a document that explains the core features and for the rest you have to read the source code for "stratum mining proxy" and/or old posts on bitcointalk.org. GBT (getblocktemplate): the server gives the client templates that the client can use to generate its own work. The client is given full block data and (if supported by server and client) this allows the client to modify the block. For instance the miner could choose which transactions to include in a block. Because of these features GBT needs to transfer more data than Stratum, so bandwidth usage is higher. These features are not supported anywhere yet, as far as I know. GBT is well documented through detailed specs. Plain getwork: the way mining was done originally. The server gives the client a block header without any transactions or any way to modify the block except for the nonce value. The client is limited to trying all possible nonce values and will then need to request more work from the server. This causes massive bandwidth usage for modern mining hardware. Like Stratum it doesn't give the miner any control over what is mined. You get the worst of both worlds. getwork with rollntime extension: allows the client a limited way to generate work by modifying the timestamp on the block header. If you process 10 nonce ranges per second (42.9 Ghps) you'd want to request 10 block headers from the server. As each second passes you update the timestamp on those block headers, allowing you to reuse the same work for the next second. Bandwidth usage goes up with hashrate. 429 Ghps would require 100 small request-response exchanges with the server to get enough work after every block change. Compare with GBT where bandwidth usage goes up with the size of the transactions (one big request-response exchange per block change). Which uses less bandwidth depends on your hashrate (getwork) and the size of the block you are hashing (GBT). TL;DR: getwork is the old way. The rollntime extension gave it back some life, but it won't scale as mining devices get faster. There are two new protocols to improve mining: Stratum which focuses on low bandwidth usage and GBT which focuses on allowing the miner to control what goes in a block.</p>]]></content:encoded> <category><![CDATA[Bitcoin Mining]]></category> <link>http://bitcoin-and-blockchain.education/BitcoinMining/655</link> <guid isPermaLink="true">http://bitcoin-and-blockchain.education/BitcoinMining/655</guid> <pubDate>Tue, 14 Jul 2020 11:38:00 +0000</pubDate> </item> <item> <title>How do you get Bitcoin?</title> <description>Bitcoin is still a thing - a thing people are confused by.

Turns out being a currency that could change the future of payments isn’t easy. WHAT IS BITCOIN? A digital currency. But unlike Visa or PayPal, there’s no centralized operation heading it up. Meaning no bank CEO and no issuing authority (think: the way the US government backs the dollar). Instead, transactions happen through a peer-to-peer network. You don’t even have to use your real identity - you could use your middle school screen name if you want. Welcome to the Wild West of the Interwebs. HOW IS THIS ALLOWED? Blockchain. Not code for Tetris. Every time something is bought or sold using bitcoin, it’s verified and publicly recorded on the blockchain. In other words, the blockchain is the digital ledger that makes bitcoin legit. HOW DO I GET BITCOIN? You have to mine for it. Not the coal kind. Mining is when computers on the network crunch through a set of puzzles. Whoever wins gets rewarded with new bitcoins and a metaphorical gold star. Or you could always just buy them from someone. I THOUGHT IT WAS FOR SMOOTH CRIMINALS. It can be. Silk Road - an online drug market that was busted a few years ago - traded in bitcoin. Because ‘following the money’ is harder to do when you can use a fake name. But there are also a lot of non-shady companies that accept bitcoin now - including Dell, Microsoft, and Expedia. OK. BUT WHY WOULD I USE IT? You probably wouldn’t right now. But as the network grows, some think it could have more mainstream applications because of its loose structure. Think: international money transfers with zero transaction fees. Some venture capital firms (including one run by the Winklevii) have invested in startups that deal with bitcoin.</p>]]></content:encoded> <category><![CDATA[Bitcoin Exchanges]]></category> <link>http://bitcoin-and-blockchain.education/BitcoinExchanges/1084</link> <guid isPermaLink="true">http://bitcoin-and-blockchain.education/BitcoinExchanges/1084</guid> <pubDate>Sun, 12 Jul 2020 11:30:00 +0000</pubDate> </item> <item> <title>Using Bitcoins on Silk Road</title> <description>Black markets on the Deep Web offer everything: money laundering and a one-stop-shop for illegal drugs and guns.

But a recent series of heists, busts and fraud have shown why these bazaars can't be trusted. In October, the FBI shut down Silk Road, the biggest online black market, seizing $3.5 million of bitcoins in the process. In November, a similar site called Sheep Marketplace was labeled a scam after it lost $6 million in users' bitcoins in an alleged hack. And last week, administrators of a revived Silk Road claimed cyber attackers sucked out all the bitcoins it held in escrow - valued at $2.7 million. This latest episode "may mark the death knell for the dark markets, " according to Nicholas Weaver, a security researcher at the International Computer Science Institute. "Between busts, scam-markets, and now mass theft, it is a task that they clearly are incapable of doing, " Weaver said. The heart of the issue is that Bitcoin - by design - doesn't work well with shady middlemen. Anyone with access to your digital wallet can empty it forever. And all transactions are irreversible. That's why it's not smart to fork over bitcoins to an underground website like Silk Road, which stands between buyers and sellers and holds on to money during a deal. "When you introduce a third party holding on to people's funds, it's absolutely antithetical to the idea of Bitcoin, " said Evan Rose, CEO of Bitcoin ATM maker Genesis. "You're giving someone cash over the Internet that you'll never be able to get back." Silk Road's new administrators said hackers exploited a Bitcoin glitch to steal funds. But in the days since the attack, it's become painfully clear that the Bitcoin system isn't to blame. Only two scenarios exist, says Andreas Antonopoulos an engineer at Bitcoin wallet service Blockchain: Silk Road's leaders were fooled into emptying all their accounts willingly, or they simply swindled their customers themselves. Those who currently use bitcoins to buy drugs, weapons or hire assassins also have something else to worry about. All transactions leave a permanent record that's traceable to specific wallets. Even though Bitcoins are technically anonymous, if they ever pull that money out in their name at a legitimate Bitcoin bank or exchange, law enforcement has a direct connection to a real identity. That's why Weaver says bitcoins are essentially "prosecution futures." Bitcoin tracing experts are already cropping up - and they're teaming up with law enforcement too. Sarah Meiklejohn is a computer scientist and graduate student at the University of California in San Diego, where she explores how people are spending their bitcoins. She said people spending bitcoins in black markets don't realize "every bitcoin is by nature a marked bill." And it's not as forgiving as actual cash. If police catch you buying something illegal in person, you get criminal charges for that single act. Bitcoin's permanent, public ledger gives prosecutors a much longer memory. "if you get caught buying drugs with bitcoins and they look at your transaction history, you get caught on every transaction you've ever made, " she said. "It's much more serious."</p>]]></content:encoded> <category><![CDATA[Bitcoin Exchanges]]></category> <link>http://bitcoin-and-blockchain.education/BitcoinExchanges/598</link> <guid isPermaLink="true">http://bitcoin-and-blockchain.education/BitcoinExchanges/598</guid> <pubDate>Fri, 10 Jul 2020 11:25:00 +0000</pubDate> </item> <item> <title>Bitcoin mining results</title> <description>Timo Hanke, a mathematical researcher and cryptocurrency expert, in collaboration with Sergio Demian Lerner, a renowned security expert, has developed a new Bitcoin mining method that can increase mining revenue by up to 20 ...</description> <content:encoded><![CDATA[<img src="/img/all_about_cryptocurrency_16_awesome_and.jpg" alt="All About CryptoCurrency: 16 Awesome and useful Bitcoin calculators" align="left" /><p>Timo Hanke, a mathematical researcher and cryptocurrency expert, in collaboration with Sergio Demian Lerner, a renowned security expert, has developed a new Bitcoin mining method that can increase mining revenue by up to 20 percent, translating to an increase of $30 million in annual profits if used by one of the biggest mining pools. The patent pending method available for licensing “involves a new design of the SHA 256 hash-engines (inside the ASIC) and an additional pre-processing step as part of the mining software (outside the ASIC)” according to the whitepaper. Through parallel processing, it re-uses “outputs that would otherwise be created and discarded on a continuous basis.” Furthermore, it achieves gains on top of other optimizations such as “timing, pipelining, path balancing, custom cell and full custom designs.” The new technology is a result of algorithmic discoveries that “were widely believed to be impossible, ” allowing for a reduction in chip silicon area and lower power consumption by using fewer gates for each hashing core. This shortcuts the number of computations required for mining, as the mining hardware can re-use information acquired over time or share information with other hashing cores. “Chip designers get a game-changing improvement over whatever they already have achieved today, ” says technology inventor Hanke. “For the Bitcoin mines of the future, AsicBoost will make all the difference between a profitable and an unprofitable mine.” The results have the potential to lead to a dramatic improvement in performance in a zero sum industry where every little gain counts. The Arms Race in Bitcoin’s Mining Industry Bitcoin mining has always been a competitive endeavor with the short-lived CPU mining period quickly giving way to GPUs, followed by ASICs. Considered an arms race as each hash-share gain increases profits at the expense of competitors, competition is intense, with hardware constantly improved and older versions quickly becoming obsolete. A dramatic illustration can be seen during a three-month period between December 2015 to March 2016 when difficulty more than doubled from 75 petahash to 175 petahash, more than halving the reward for mining hardware in use during December 2015. The increase in difficulty followed an increase in price which reached a low of approximately $170 in 2015 to stand currently at $440.</p>]]></content:encoded> <category><![CDATA[Bitcoin Mining]]></category> <link>http://bitcoin-and-blockchain.education/BitcoinMining/272</link> <guid isPermaLink="true">http://bitcoin-and-blockchain.education/BitcoinMining/272</guid> <pubDate>Wed, 08 Jul 2020 11:22:00 +0000</pubDate> </item> <item> <title>Bitcoin mining hash</title> <description>If you’ve already heard about Bitcoin, you probably know that mining is one of the core concept underlying this blockchain technology.

You’ve maybe also heard that mining involves thousands of powerful computers which solve some magical puzzles. But do you really know how does mining works under the hood? Science behind Bitcoin Despite the fact that the blockchain technology takes advantage of a few sophisticated numerical algorithms, the underlying concepts are quite straightforward. And definitely you don’t need an engineering degree in programming to grasp the gist of this revolutionary technology! Cryptographic hash function Hash functions belong to a very useful class of algorithms that transform any data into a short message which then we can easily compare and process. Simple example of that could be a mathematical function which as an output gives the remainder of division by 1000 (modulo operation). You can think about hashes as fingerprints of data. Cryptographic hash functions must meet some conditions, such as: be deterministic — that means for the same input function have to always return the same hash you shouldn’t be able to guess the input from hash except by trying all possibilities, which is impossible even for supercomputers small change in the input should result in a completely different hash it should be extremely hard to find 2 different inputs which give the same hash (like winning Powerball 10 times in a row hard!!!) Cryptographic hash functions are diligently analyzed before they are recommended to production use. For instance National Institute of Standards and Technology organized several contests for hash functions in which finest minds in the world tried to crack or find vulnerabilities in the list of proposed algorithms. Bitcoin relies heavily on this properties when it comes to mining blocks. If you’re curious, an actual implementation uses well known and battle-tested algorithm called SHA-256 .

Markets move in cycles and it is not surprising that, three years after the speculative bubble at the end of 2013, bitcoin is enjoying a resurgence of interest. The virtual currency has been declared dead by experts and the mainstream media more times than it’s worth counting, but it appears to be stubbornly resistant to demise. This time around, bitcoin’s move above $1, 000 takes place in very different circumstances. The bitcoin and wider blockchain ecosystem is significantly more mature, with multiple large exchanges rather than one huge, poorly-run and insecure exchange (the ill-fated MtGox) providing a hub for trading and a catastrophic single point of failure. Awareness is far greater, liquidity is higher. The rise in price has been rapid (and somewhat choppy, to say the least) but does not, at the time of writing, have the character of a bubble – that irrational exuberance that sees a period of multiple double-digit daily increases, culminating with a final sharp spike upwards and an inevitable and brutal crash. The global economic picture Moreover, there are reasons for bitcoin’s rise beyond mere speculative interest. Like the bitcoin ecosystem, the global economic crisis has also matured over the past three years. We now have a better picture of the problems facing us – and how bitcoin fits into that. China has always been a big player in the bitcoin space, accounting for around 70 percent of bitcoin mining (the process by which new bitcoins are created, and transactions on the bitcoin network approved) and up to 90 percent of trading. The Chinese government’s move to devalue the Yuan to make its state-run economy more competitive, and the strengthening US dollar, have made bitcoin even more interesting to Chinese speculators. Moreover, bitcoin has become a popular and proven means of circumventing the capital controls imposed by the authorities. If you want to move money out of China, there are various options – and bitcoin is one of them. No wonder it has seen increased demand as wealthy Chinese seek to store value in assets and currencies other than Yuan. China also forms a large piece of the global economic puzzle. What happens in the next year will shape the rest of the world. How much further their economy will slow; the problems of China’s vast and opaque shadow banking sector; their interaction with the US and the Trump presidency, which is notably more hostile towards Chinese imports and labour than the previous administration; what they do with their very significant dollar reserves in response – all of these have yet to be answered. Later this year will see the 19th National Congress of the Communist Party of China, at which new leadership will be elected, including five out of the seven members of the Politburo Standing Committee – the highest decision-making body in the country. This is closely watched due to the significant scope for uncertainty and its economic impacts as potential candidates jockey for power. Bitcoin offers something here for the scared Chinese middle classes. In fact, any form of uncertainty increasingly favors bitcoin as a ‘safe haven’ asset, either as a means of moving money across borders, or as a means of protecting it from bail-ins and erosion by inflation. Bitcoin has not previously proven a good store of value, but with growing market cap and awareness, volatility is far lower than it was. On the long-term timescale, it has posted attractive gains, where the Yuan has only slid one way.</p>]]></content:encoded> <category><![CDATA[Bitcoin Exchanges]]></category> <link>http://bitcoin-and-blockchain.education/BitcoinExchanges/610</link> <guid isPermaLink="true">http://bitcoin-and-blockchain.education/BitcoinExchanges/610</guid> <pubDate>Sat, 04 Jul 2020 11:11:00 +0000</pubDate> </item> <item> <title>Bitcoin ASIC miners Comparison</title> <description>We’ve decided to do a quick comparison between the different options that you have for around 30 MHS Scrypt ASIC miners that are available on the market at the moment in order to give you an idea on how they compare to each ...</description> <content:encoded><![CDATA[<img src="/img/antminer_s7_473t_bitcoin_miner_asic.jpg" alt="Antminer S7 4.73T Bitcoin miner ASIC miner 4730G BTC Mining" align="left" /><p>We’ve decided to do a quick comparison between the different options that you have for around 30 MHS Scrypt ASIC miners that are available on the market at the moment in order to give you an idea on how they compare to each other. We have a GAWMiners Falcon Miner (ZeusMiner Thunder X3), Silver Fish Blade Miner and Innosilicon A2Mini Miner that we have either tested already or are currently testing (detailed reviews of the last two to follow soon). On the photo above you can see the three miners on top of each other, so that you can get a good idea on how they compare in terms of size. Do note that they are all different not only in terms of size, but also in terms of power consumption and completeness, and they also do come with different prices as well. Here is a table to compare and summarize the three miners that are all averaging about 28 MHS or slightly more in terms of actual hashrate according to their specs and what we have seen so far in our tests. The Falcon is the largest one, essentially a ZeusMiner Thunder X3 from the earlier batches as the newer units do come with a bit different design and Zeus has already announced new miners with lower power consumption, though these are not yet shipping. The A2Mini miner based on Innosilicon A2 chips is the second one in terms of physical size, however this miner differs than the other two with the fact that it contains an integrated power supply and Raspberry Pi controller all built inside the case. The smallest one is the Silver Fish Blade, an interesting open frame solution that is not very widely available and popular outside of China. All of the miners above have their own advantages and disadvantages, but the price is probably the deciding factor for every miner when considering the return of investment expected. This is especially true now when the Litecoin network difficulty has climbed up to a level that ensures just a bit over 1 LTC per day to be mined with any of these Scrypt ASIC miners. Obviously the A2Mini is the worst choice in terms of price, though we do like the miner a lot as it comes as a complete solution ready to be used out of the box and with the lowest power usage. At the price that it is currently being sold however it is not a wise choice and A2 really does need to update their prices. The Silver Fish blade is also an interesting solution, especially with the lower power usage it offers as compared to ZeusMiner’s alternative, here however we do not like very much the not so effective for cooling open design and the Windows only software miner available for the device along with network only connectivity. The price of the Silver Fish is also quite high compared to Zeus’, and even though the ZeusMiner and the branded products from their partners such as GAW’s Falcon with the highest power consumption it is still the most interesting solution in terms of price. And with the announcement of the new lower power usage products that offer higher hashrate at lower price ZeusMiner is probably the most interesting choice for a Scrypt ASIC miner at the moment as it should be able to offer the fastest ROI at the moment.</p>]]></content:encoded> <category><![CDATA[Bitcoin Mining]]></category> <link>http://bitcoin-and-blockchain.education/BitcoinMining/594</link> <guid isPermaLink="true">http://bitcoin-and-blockchain.education/BitcoinMining/594</guid> <pubDate>Thu, 02 Jul 2020 11:10:00 +0000</pubDate> </item> <item> <title>ASICs Bitcoin mining</title> <description>Avalon, the first company to manufacture ASIC mining chips and sell them to consumers, has returned to the marketplace with a new chip after an absence of several years.

Avalon has announced a new A3218 mining chip that will be released in the Avalon6 miner. According to Avalon, each server can process 3.65 TH/s at a power efficiency of 0.29 W/GH. Each server is composed of 80 of the Avalon A3218 chips. The system requires, at minimum, a 12VC DC, 1, 100 watts PSU output. Unlike the other companies that have been developing 14nm chips, Avalon decided to stick with its 28nm ASIC chip. “What I can tell you is that Avalon was offered the 14nm Samsung chip many months ago, and they declined, ” explained Sean Walsh, Founder of BlockC, in an interview with Bitcoin Magazine . “The 14nm process node is very new, very slow to design/produce, very difficult, very expensive and doesn't currently yield efficiency gains that even come close to compensating for all this. Avalon will produce at smaller process nodes, but only once it actually makes financial sense to do so.” Canaan-Creative, the parent company of Avalon, and BlockC have recently announced a partnership that results in BlockC becoming the global distributor (except in China) of all Avalon products and services in the bitcoin space. According to Walsh, 1 petahash of processing power would cost approximately $350, 000 to $360, 000. This is quite a bit cheaper than the only other seller on the market, Bitmain, for two reasons, ” Walsh said. “First, Bitmain is currently advertising prices of about $380, 000 per petahash. Second, Bitmain is not shipping any miners until mid-December, which is a full month later than BlockC.co ship dates. One Petahash currently earns about $90, 000 per month in gross profit (after paying electric bills). Running the numbers, BlockC/Avalon is about 7 percent lower on sales price, plus the 25 percent you gain by emerging your PH a month sooner. That’s an effective savings of over 30 percent.” BlockC expects the first batch of Avalon6 miners to arrive in their California datacenters by November 12, 2015. It is currently selling the servers in batches of 10, providing 36.5 TH/s for $14, 950. Who is Avalon? Avalon is one of the oldest bitcoin mining hardware companies in the ecosystem. Canaan Creative, the parent company of Avalon, was founded in 2012 by NG Zhang, Jiaxuan Li, who goes by the name Lee, and Xiangfu Liu. The first miner they released was the Icarus, which was a programmable Xylinx FPGA chip released in the beginning of 2012. Soon after, they released the Lancelot, which was also based on the Xylinx FPGA.</p>]]></content:encoded> <category><![CDATA[Bitcoin Mining]]></category> <link>http://bitcoin-and-blockchain.education/BitcoinMining/356</link> <guid isPermaLink="true">http://bitcoin-and-blockchain.education/BitcoinMining/356</guid> <pubDate>Tue, 30 Jun 2020 11:03:00 +0000</pubDate> </item> <item> <title>Bitcoin template</title> <description>Last week, lead Bitcoin developer Gavin Andresen and other Bitcoin Core developers joined the recently established MIT Digital Currency Initiative.

This was widely interpreted as an MIT takeover of the roles of leadership, funding and co-ordination of Bitcoin technical development, previously claimed by the Bitcoin Foundation. In parallel, Bitcoin policy think tank Coin Center is claiming the role of interface to policy makers and regulators, with the publication of a framework for state digital currency regulation. The report, titled “State Digital Currency Principles and Framework, ” is a model for digital-currency-specific regulations and laws. The report provides a template with structure, definitions and language for the essential components of any digital currency law: who must be licensed, how start-ups are encouraged, how solvency is guaranteed and other necessary elements. Recently, Bitcoin-friendly bills have been proposed in Utah, New Hampshire and New York City. Texas, Kansas, California, Pennsylvania and North Carolina also have expressed interest in Bitcoin regulations, and New York has proposed the controversial “Bitlicense” scheme, which many observers consider far too strict. Coin Center hopes that states will use the report as a template for their own bills and regulations. “The state that reaps the benefits of new technologies, new jobs and enhanced financial inclusion will be the state that first discovers a path worth following, ” says Executive Director Jerry Brito. “We hope this report will help in that endeavor.” Brito adds that, to be a leader in the future of financial technology, a state must carefully forge a path toward consumer protection and avoid the pitfalls of inartful and unnecessarily costly regulation. Of course, striking an optimal balance between necessary crime prevention and consumer protection on the one hand and equally necessary innovation and technology leadership on the other is challenging. The recent initiative of the Isle of Man government to create a balanced regulatory environment that offers “freedom to flourish” to innovative fintech companies, while keeping crime and fraud out, is an important development in that respect. The Coin Center report emphasizes that only operators with unilateral control of customer funds should be subject to a license requirement, and that anti-money laundering (AML) requirements, if absolutely necessary at all, should match, but not exceed, federal standards. “Intermediaries who do not assume a position of trust, nonfinancial uses and individual access are digital currency innovations that should be encouraged, ” the report says. “These intermediaries can benefit both consumers and businesses through improved financial privacy, financial inclusion, and vibrant technology-based economies. These uses should not be burdened by compliance costs that lack concomitant consumer protection benefits.” Brito, who is also a professor of Law at George Mason University, co-authored the report “.” Coin Center is a not-for-profit research and advocacy center focused on public policy issues facing cryptocurrency technologies such as Bitcoin. “Our mission is to build a better understanding of these technologies and to promote a regulatory climate that preserves the freedom to innovate using blockchain technologies, ” says the Coin Center website. “We do this by producing and publishing policy research from respected academics and experts, educating policymakers and the media about blockchain technology, and by engaging in advocacy for sound public policy.” It’s probably too early to speculate on which organizations will co-ordinate the technical and policy-related aspects of Bitcoin development, but it seems clear that MIT and Coin Center are establishing strong leadership positions.</p>]]></content:encoded> <category><![CDATA[Bitcoin Exchanges]]></category> <link>http://bitcoin-and-blockchain.education/BitcoinExchanges/1010</link> <guid isPermaLink="true">http://bitcoin-and-blockchain.education/BitcoinExchanges/1010</guid> <pubDate>Sun, 28 Jun 2020 11:03:00 +0000</pubDate> </item> <item> <title>Bitcoin Gambling sites</title> <description>Bitcoin (BTC) is the most popular cryptocurrency currently used around the world today.

With over 2.5 million users and an ever growing community, bitcoins are rising in value with no signs of stopping. Conceptualized in 2008, bitcoins are a fresh currency with exceptional potential. Using world renowned security protocols, faster transactions than traditional banking, inexpensive fees and complete anonymity, bitcoins are emerging as a popular alternative to common currencies. By improving on many elements that currencies around the world suffer from today such as inflation and manipulation, BTC has brought the next generation of stabilized currency into the forefront. Take note that bitcoins do not exist in the physical world as actual coins or tender, they are stored entirely in bitcoin wallets, which is essentially a personal bitcoin bank account. However, no banks are involved with bitcoin resulting in much cheaper fees than normal banking. Bitcoin miners use specialized hardware and software to approve all bitcoin exchanges between wallets to verify transaction integrity and also process complex algorithms which release new bitcoins onto the market when solved. Every time the algorithm is solved, a new algorithm is provided to the miners but with added complexity, delaying the release of the next set of bitcoins to prevent inflation. More businesses are accepting bitcoins as a legitimate method of payment every single day; as time progresses the value of a single bitcoin will continue to rise; investing in bitcoins early is a wise and objectively safe decision.
