Bitcoin (BTC) is the world’s first decentralized digital currency and payment system and is by far the most known and valuable cryptocurrency. It was created in 2009 by an anonymous person or group called Satoshi Nakamoto. Bitcoin enables transactions to be sent peer-to-peer without passing through a central authority. The transactions are recorded on a decentralized public ledger called the blockchain and each payment acquires a small transaction fee to cover the cost of the network. The total supply of Bitcoin is 21 million and it’s smallest unit of bitcoin is called a Satoshi, it’s a hundred millionth of a bitcoin – 0.00000001 BTC. The creation of Bitcoin’s is happening through mining. Miners have the task to validate transactions and keep the network secure. Their efforts are rewarded by new minted Bitcoins and transactions fees. Bitcoin can be exchanged for fiat or other cryptocurrencies, products and services. Over 100,000 merchants and vendors accepts bitcoin as a payment.
Peer to peer (P2P) electronic cash is simply described as online money sent from one person to another without the need for a trusted third-party. As described in the original Bitcoin whitepaper by Satoshi Nakamoto, P2P cash makes use of digital signatures as part of the solution, but the main benefits are lost if a trusted third party is still required to prevent fraud. This makes P2P cash a trustless and safe way to transact without the need of intermediaries.
If you have the required hardware, you can mine bitcoin even if you are not a miner. There are different ways one can mine bitcoin such as cloud mining, mining pool, etc. For cloud mining, all you need to do is to connect to the datacenter and start mining. The good thing about this is that you can mine from anywhere and you don’t need a physical hardware to mine.
Here goes a screenshot from my e-mechanical workstation; although and as you can see we are half way routing the traces but progressing. I also have the BOM or other layers if you need to see anything in particular. You think you can help us market this product? we'd like to compete with Intel (and Bitmad lol) for a Pro Turn-Key Crypto Solution. You in?
With the largest variety of markets and the biggest value - having reached a peak of 18 billion USD - Bitcoin is here to stay. As with any new invention, there can be improvements or flaws in the initial model however the community and a team of dedicated developers are pushing to overcome any obstacle they come across. It is also the most traded cryptocurrency and one of the main entry points for all the other cryptocurrencies. The price is as unstable as always and it can go up or down by 10%-20% in a single day.
每一个细节都能反映很多事情，正如社会本身。 Truth alone triumphs ，还是 money, fashion, 或是 lies ？ Jamal 回答不了。他没有受过教育，没有被灌输过所谓的 National motto 。如果根据他的亲身经历去理解，他真的不知道这些东西究竟那个是王道。有钱的黑社会老大、著名的男演员、装成善人却弄瞎小孩子的乞讨集团首领都混得不错， truth 在哪里？当审问他的警官说“我五岁的女儿都会回答这道题”的时候， Jamal 问了他两个问题，贫民窟 5 岁小孩都能回答的问题，警官却答不出。这就是贫富阶级的差别，受教育不同、吃的东西不同，去的地方也不同…… 开篇警官审问 Jamal 的镜头，让我们想起与伊拉克有关的各种虐待和拷问。警官说“外面还有许多强盗、强奸犯、诈骗犯、勒索犯等我去抓，你快招了吧，省省咱俩的时间”，可是我们自始至终只看到警察追赶在私人土地上玩耍的穷孩子，殴打在泰姬陵揽客的孤儿，以及无视被纵火的穆斯林教徒、一心在车里打牌。我们还看到白色轿车穿梭在狭窄胡同的穷人堆里的，烧成废墟的贫民窟和孟买城中拔地而起的高楼。只要用心，我们能看到的太多了。整个印度的社会风貌都展现在我们面前，一个 Latika 算什么。只看到爱情故事的人，是选择性失明而已。
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.
To keep the block generation time equal to ten minutes on average, both Bitcoin and Bitcoin Cash use an algorithm adjusting the mining difficulty parameter. This algorithm is called the difficulty adjustment algorithm (DAA). Originally, both Bitcoin and Bitcoin Cash used the same difficulty adjustment algorithm, adjusting the mining difficulty parameter every 2016 blocks. Since 1 August 2017, Bitcoin Cash also used an addition to the DAA, called an Emergency Difficulty Adjustment (EDA) algorithm. EDA was used alongside the original DAA and it was designed to decrease the mining difficulty of Bitcoin Cash by 20%, if the time difference between 6 successive blocks was greater than 12 hours.
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。
The would-be hard fork with an expanded block size limit was described by hardware manufacturer Bitmain in June 2017 as a "contingency plan" should the bitcoin community decide to fork; the first implementation of the software was proposed under the name Bitcoin ABC at a conference that month. In July 2017, the Bitcoin Cash name was proposed by mining pool ViaBTC. The change, called a fork, took effect on 1 August 2017. As a result, the bitcoin ledger called the blockchain and the cryptocurrency split in two.
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.
