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.
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.

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.
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.
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.
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。
