The first pure mined ERC20 Token for Ethereum, using the soliditySHA3 hashing algorithm. This is a smart contract which follows the original Satoshi Nakamoto whitepaper to form a fundamentally sound trustless currency. This combines the scarcity and fair distribution model of Bitcoin with the speed and extensibility of the Ethereum network. Thus, it is named 0xBitcoin or 0xBTC where 0x represents the Ethereum Network and ecosystem.
Bitcoin mining: how is a block header of 80 bytes processed in SHA-256? Isn't it too big?
The whole process of bitcoin mining was making sense to me until a moment of madness an hour ago, if there is 80 bytes of data to be processed in SHA-256, that's 640 bits of data to be processed in SHA-256. In this 80 bytes we have: 4 bytes (version), previous block hash (32 bytes), merkle root (32 bytes), time (4 bytes), bits (4 bytes), nonce (4 bytes). I thought SHA-256 accepted 512 bits of data, so that's 64 bytes of data. And on top of that, I need to add the length of the data to be processed in the last 64 bits of this 512 bits input but 64 bytes is well over the limit. What am I missing here? Can someone help hear it up for me? Thanks

''' Bitmain has made many major developments in 2018, including the 7nm ASIC chip for SHA-256 mining, the AI division “Sophon”, the BCH fork, as well as its expanding operations in the U.S. In the past year, Bitmain launched a series of new products that may boost the mining efficiency, including a firmware that supports the AsicBoost optimization that available on S9 and BM1387-based models (R4, S9i, S9j, T9, and T9+). In addition, the next generation 7nm ASIC chip, designed for SHA-256 mining is definitely a great milestone for Bitmain in 2018. The ASIC chip was used in Bitmain’s two latest products launched in late November, the Antminer S15 (28 TH/s, 57J/TH) and T15 (23 TH/s, 67J/TH). Bitmain also indicated that “the chip provides significant improvements in terms of performance, power consumption and delivering outstanding performance”.

PSA: For SHA-256 Bitcoin mining, the BW.com pool has been averaging 5+% higher than any of the previous pools since its inception over a week ago.
I just realized it today, but +5% over the term of a contract is pretty substantial! (If it's not a new pool, forgive me. I've never noticed it before, and even if it has been around, it definitely looks like they've now got their sh*t together.)
Mining other SHA-256 coins with Antminer S7 beside Bitcoin?
Hey guys, I hope this is not off topic. I have 2x Antminer S7 which one I usually (but not always) point to Nicehash. After some extensive Googling I get a vague idea that it is possible to mine these SHA-256 based Altcoins with it, but nothing concrete. I'm guessing the answer is "yes", but would like confirmation before I stop mining Bitcoin and give it a try. Also, is there a SHA-256 auto-profit switch pool to direct the Antminers to? TIA
Bitcoin is the currency of the future & Genesis Mining is the largest cloud mining company on the market. Mine bitcoin through the cloud, get started today! Bitcoin mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network. This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. How Bitcoin Mining Works. Before you start mining Bitcoin, it's useful to understand what Bitcoin mining really means. Bitcoin mining is legal and is accomplished by running SHA256 double round hash verification processes in order to validate Bitcoin transactions and provide the requisite security for the public ledger of the Bitcoin network. Bitcoin mining is the process by which new bitcoins are entered into circulation, but it is also a critical component of the maintenance and development of the blockchain ledger. Total Customer: 110398 Total Mining : 21.1841 BTC Last Proof of Payment Bitcoin. You can review Bitcoin payments. Regular payments are made.Bitcoin mining began to grow day by day, from all over the world People doing cloud gpu mining and in this way they provide very good incomes.
