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.
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。
EDA adjustments caused instabilities in mining difficulty of the Bitcoin Cash system, resulting in Bitcoin Cash being thousands of blocks ahead of Bitcoin. To address the problem with stability, a change of the Bitcoin Cash DAA was implemented and the EDA cancelled. The change took effect on 13 November 2017. After the change, the Bitcoin Cash DAA adjusts the mining difficulty after each block. To calculate the difficulty for a new block, the Bitcoin Cash DAA uses a moving window of last 144 blocks.
Bitcoin (BTC) is a consensus network that enables a new payment system and a completely digital currency. Powered by its users, it is a peer to peer payment network that requires no central authority to operate. On October 31st, 2008, an individual or group of individuals operating under the pseudonym "Satoshi Nakamoto" published the Bitcoin Whitepaper and described it as: "a purely peer-to-peer version of electronic cash, which would allow online payments to be sent directly from one party to another without going through a financial institution."
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.
At the time of the software upgrade (also known as a fork) anyone owning bitcoin was also in possession of the same number of Bitcoin Cash units. The technical difference between Bitcoin Cash and Bitcoin is that Bitcoin Cash allows larger blocks in its blockchain than Bitcoin, which in theory allows it to process more transactions per second. Bitcoin Cash was the first of the Bitcoin forks, in which software-development teams modified the original Bitcoin computer code and released coins with “Bitcoin" in their names, with "the goal of creating money out of thin air." In relation to Bitcoin it is characterized variously as a spin-off, a strand, a product of a hard fork, an offshoot, a clone, a second version or an altcoin. On 1 August 2017 Bitcoin Cash began trading at about $240, while bitcoin traded at about $2,700.
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.
主人公贾马尔就是作者心目中的神，他对美好事物的不懈追求被影片渲染得感人至深。他在任何情况下都从不放弃对心中圣洁化身的拉提卡的追求，无论是金钱的诱惑，还是生命受到威胁，都没有窒灭他的所求。在看到自己心爱的人被哥哥抛弃时，一向尊重哥哥的他怒不可遏。他参加百万富翁的节目，不是为了成为百万富翁，而是为了寻找拉提卡。他的性格是那样单纯，他的心灵是那样干净，这简直就是作者富有诗意的创造，寄托着作者对美好人性的无限渴望和对世俗对人性美的冲击的深深忧虑。银幕上这样一个简单、率直又可爱的个性赢得了许多观众的“垂青”，他时常说的一句“It's our destiny.”（这是我们的命中注定），更引来了无数粉丝的尖叫。的确，在现实生活中，一个拥有这样美好心灵的人都是很值得我们尊敬的，但在他没有成功以前，这样的人很容易被人看作为是“一根筋”。
