Bitcoin Cash (BCH) is hard fork (a community-activated update to the protocol or code) of Bitcoin that took effect on August 1st, 2017 that increased the block size to 8MB, to help the scale the underlying technology of Bitcoin.Nov 16th 2018: BCH was hard forked again and split into Bitcoin SV and Bitcoin ABC. Bitcoin ABC became the dominant chain and took over the BCH ticker as it had more hashpower and majority of the nodes in the network.
Bitcoin is the world’s first cryptocurrency which works on a completely decentralized network known as the blockchain. The blockchain network consists a link of blocks that are secured using cryptography and record all the transactions. Bitcoin was first presented to the world in 2009 by an anonymous identity known as Satoshi Nakamoto. As Bitcoin works on a decentralized network, it is completely free from the involvement of third-party financial institutions or central banks. The Bitcoin blockchain facilitates instant peer-to-peer transactions at minimum transactions fees required to maintain the network. The total number of Bitcoins is fixed at 21 million with its smallest unit being referred to as Satoshi. Each Satoshi represents a hundred millionth part of Bitcoin which means that 100,000,000 Santoshi = 1 BTC. Additional Bitcoins are generated by a process known as mining. Bitcoins are mined by professional miners solving complex computational equations. For each Bitcoin mined, the miners are rewarded with either more coins or transaction fees. The miners also validate all transactions on the Bitcoin network as well as look after the network security. Bitcoin can be exchanged with fiat currencies or other digital currencies. There are over 100,000 merchants and vendors accepting Bitcoin all over the world.
So, Reppo. You wanted to talk-the-tech if my instincts are correct? Friends and I are designing a 8 layers stack module based off the Avalon's A3255 55nm mining chip with a fpga/firmware (source borrowed). This incorporate the full trading bot machine learning and TA indicator accelerators, and of course a crypto wallet secured by a custom AVR. We're down to 1.694AMP per hashboard (14chips each x 5 =70).
There are two factions of bitcoin supporters, that support large blocks or small blocks. The Bitcoin Cash faction favors the use of its currency as a medium of exchange for commerce while the Bitcoin-supporting faction view bitcoin's primary use as that of a store of value. Some Bitcoin supporters like to call Bitcoin Cash “Bcash,” “Btrash,” or simply a scam, while Bitcoin Cash advocates insist that their implementation is the pure form of Bitcoin.
Bitcoin Cash trades on digital currency exchanges including Bitstamp, Coinbase, Gemini, Kraken, Bitfinex, and ShapeShift using the Bitcoin Cash name and the BCH ticker symbol for the cryptocurrency. On 26 March 2018, OKEx removed all Bitcoin Cash trading pairs except for BCH/BTC, BCH/ETH and BCH/USDT due to "inadequate liquidity". As of May 2018, daily transaction numbers for Bitcoin Cash are about one-tenth of those of bitcoin.
Bitcoin Cash was launched in August 2017, as a direct response to small block sizes on the Bitcoin code. 1MB block sizes were not meeting the demand of the growing community, so a group of dissatisfied crypto enthusiasts decided to create a ‘hard fork’ of the Bitcoin blockchain, with an increased 8MB block size. No one person currently takes credit for the token’s creation; rather it is attributed to a de-centralized group of developers.
Rising fees on the Bitcoin network contributed to a push by some in the community to create a hard fork to increase the blocksize. This push came to a head in July 2017 when some members of the bitcoin community including Roger Ver felt that adopting BIP 91 without increasing the block-size limit favored people who wanted to treat bitcoin as a digital investment rather than as a transactional currency. This push by some to increase the block size met a resistance. Since its inception up to July 2017, Bitcoin users had maintained a common set of rules for the cryptocurrency. Eventually, a group of bitcoin activists, investors, entrepreneurs, developers and largely China-based miners were unhappy with Bitcoin's proposed SegWit improvement plans meant to increase capacity and pushed forward alternative plans for a split which created Bitcoin Cash. The proposed split included a plan to increase the number of transactions its ledger can process by increasing the block size limit to eight megabytes.
而 Jamal 是个不折不扣的理想主义者。他善良而执着，对 Latika 一直不肯放弃。 Salim 在火车上数钱的时候， Jamal 脑子里想的都是 Latika ，兄弟俩的人生观一目了然。演员 Dev Patel 现实中也是只有 18 岁，有人说 Jamal 看起来太单薄，跳起舞来都是长手长脚的。但是这有什么关系呢？外型虽然薄弱，意志却无比坚强。 开头被拷打时，胖警察报告审了他一夜，除了名字什么都没问出来——“ He’s a tough guy.” 他的长官说“ What the hell can a slumdog possibly know” 的时候，背后被电晕的 Jamal 吐了一口血：“ The answers.” 这个镜头，我印象非常深刻。 18 岁的 Jamal Malik 因为这种坚强而显得格外性感。如果说这部电影是个童话，那也一定是因为 Jamal 这种近似不可能的执着和坚持，而不是男女主人公的离奇爱情故事。选不出“ Truth Alone Triumphs.” 的 Jamal ，他的人生故事却是这句话的完美诠释。 如果 Salim 是那个社会的代表型人物， Jamal 就是印度人民的精神象征，这就解释了为什么 Jamal 的天真善良和理想主义是理所当然的，也解释了为什么 Jamal 赢大奖后人们都为他兴奋欢呼。
