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。
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.
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.
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.
