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.[36]

  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。

The split originated from what was described as a "civil war" in two competing bitcoin cash camps.[18][29] The first camp, supported by entrepreneur Roger Ver and Jihan Wu of Bitmain, promoted the software entitled Bitcoin ABC (short for Adjustable Blocksize Cap) which would maintain the block size at 32MB.[29] The second camp led by Craig Steven Wright and billionaire Calvin Ayre put forth a competing software version Bitcoin SV, short for "Bitcoin Satoshi's Vision," that would increase the block size limit to 128MB.[26][29]

  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。

  为什么不是爱情童话?抱歉我要用很世俗的眼光来分析男女主人公的感情,但是我一贯不相信一个人一生非另一个人不可,除非那个人的意义上升到了另一个高度。 Jamal 的理想主义在那种社会环境下意味着他始终需要一个精神寄托。小的时候是那个男明星, Jamal 为了他的签名可以跳进粪坑。而母亲死后, Jamal和哥哥一直在过着颠沛流离的日子,兄弟感情又不是纯友爱,只能说又爱又恨的。他唯一的朋友,他生命中唯一美好的事物就是 Latika 了。即使失散多年 Jamal 也忘不了 Latika ,因为寻找她是他生命的主要意义,是他活着的理由。因此,我认为这种近似强迫症的不现实的坚持其实是可能的,有着现实意义,不是童话。有人说 Freida Pinto 过于漂亮,我很同意。 Jamal 认为 Latika 是世上最美的女人,而 Pinto 也差不离了;如果 Latika 其实没有那么漂亮,就更能体现出她对于 Jamal 的精神意义。    

什么Cryptocurrency是最容易开采


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.

Bitcoin mining saps energy, costly, uses more power and also the reward delays. For mining, run software, get your wallet ready and be the first to solve a cryptographic problem and you get your reward after the new blocks have been added to the blockchain.Mining is said to be successful when all the transactions are recorded in the blockchain and the new blocks are added to the blockchain.

什么是使用Cryptocurrency的优势


  MD5还广泛用于操作系统的登陆认证上,如Unix、各类BSD系统登录密码、数字签名等诸多方。如在UNIX系统中用户的密码是以MD5(或其它类似的算法)经Hash运算后存储在文件系统中。当用户登录的时候,系统把用户输入的密码进行MD5 Hash运算,然后再去和保存在文件系统中的MD5值进行比较,进而确定输入的密码是否正确。通过这样的步骤,系统在并不知道用户密码的明码的情况下就可以确定用户登录系统的合法性。这可以避免用户的密码被具有系统管理员权限的用户知道。MD5将任意长度的“字节串”映射为一个128bit的大整数,并且是通过该128bit反推原始字符串是困难的,换句话说就是,即使你看到源程序和算法描述,也无法将一个MD5的值变换回原始的字符串,从数学原理上说,是因为原始的字符串有无穷多个,这有点象不存在反函数的数学函数。所以,要遇到了md5密码的问题,比较好的办法是:你可以用这个系统中的md5()函数重新设一个密码,如admin,把生成的一串密码的Hash值覆盖原来的Hash值就行了。

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.

On 26 March 2018, OKEx removed all Bitcoin Cash trading pairs except for BCH/BTC, BCH/ETH and BCH/USDT due to "inadequate liquidity".[5] As of May 2018, daily transaction numbers for Bitcoin Cash are about one-tenth of those of bitcoin.[5]

比特币是有史以来持续回升


Both Bitcoin as well as Bitcoin Cash use a proof-of-work algorithm to timestamp every new block. The proof of work algorithm used is the same in both cases. It can be described as a partial inversion of a hash function. Additionally, both Bitcoin and Bitcoin Cash target a new block to be generated every ten minutes on average. The time needed to calculate a new block is influenced by a parameter called the mining difficulty. If the total amount of mining power increases, an increase of the mining difficulty can keep the block time roughly constant. Vice versa, if the mining power decreases, a decrease of the mining difficulty can keep the block time roughly constant.[36]

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.

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.

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.[36]

在这一段中,萨利姆成为了真正的萨利姆。看着电视里的贾马尔,萨利姆心中是感动,是懊悔,是骄傲,他虽然嘴上说“他是个疯子”,但实际上对能有这样一个灵魂圣洁的弟弟,他发自内心的骄傲。他让拉提卡走,他知道那意味着什么,导演特意给了打电话的贾维德一个特写,表明了萨拉姆内心的挣扎和害怕,他知道那意味着死亡。但作为一个男子汉,他从来都是说一不二的,他说“他那儿我来摆平”,同样是气势如虹,萨拉姆做事从不需要解释,他不希望弟弟担心,于是,他说:“你别无选择”,的确,拉提卡的每一次选择实际上都是萨拉姆替她做的,无论是好的,或是坏的,他这句话的潜台词,分明是在托付拉提卡,好好照顾贾马尔,他是我唯一的弟弟。“原谅我所做的一切”,既是对拉提卡说,也是对远处的弟弟贾马尔说的,那一句话里,包含的是兄长对弟弟的爱,是父亲对儿子的爱,是长辈对晚辈的爱,是对自己血脉另一部分的爱,他让拉提卡好好活着,也正是让贾马尔好好活着。当他躺在装满钞票的浴缸里时,他生平的两个愿望都得到了实现:第一,他想成为百万富翁,他此刻拥有了钞票,他温柔地触摸着它们;第二,他想要成为弟弟的保护神,他要弟弟过的好,看到他和拉提卡能够团聚,这个愿望也实现了,他的人生得到了升华,他的完美旅程结束了。
