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.

Rising fees on the Bitcoin network contributed to a push by some in the community to create a hard fork to increase the blocksize.[11] 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.[12][13] 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.[12] Eventually, a group of bitcoin activists,[14] investors, entrepreneurs, developers[12] 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.[15] 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.[12][13]

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.

被Blockchain一样Cryptocurrency


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.

为什么Cryptocurrency发明


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]

在古代,加密是由许多办法完成的。在中国较“流行”使用淀粉水在纸上写字,再浸泡在碘水中使字浮现出来。而外国就不同了,最经典的莫过于伯罗奔尼撒战争。公元前405年,雅典和斯巴达之间的伯罗奔尼撒战争已进入尾声。斯巴达军队逐渐占据了优势地位,准备对雅典发动最后一击。这时,原来站在斯巴达一边的波斯帝国突然改变态度,停止了对斯巴达的援助,意图是使雅典和斯巴达在持续的战争中两败俱伤,以便从中渔利。在这种情况下,斯巴达急需摸清波斯帝国的具体行动计划,以便采取新的战略方针。正在这时,斯巴达军队捕获了一名从波斯帝国回雅典送信的雅典信使。斯巴达士兵仔细搜查这名信使,可搜查了好大一阵,除了从他身上搜出一条布满杂乱无章的希腊字母的普通腰带外,别无他获。情报究竟藏在什么地方呢?斯巴达军队统帅莱桑德把注意力集中到了那条腰带上,情报一定就在那些杂乱的字母之中。他反复琢磨研究这些天书似的文字,把腰带上的字母用各种方法重新排列组合,怎么也解不出来。最后,莱桑德失去了信心,他一边摆弄着那条腰带,一边思考着弄到情报的其他途径。当他无意中把腰带呈螺旋形缠绕在手中的剑鞘上时,奇迹出现了。原来腰带上那些杂乱无章的字母,竟组成了一段文字。这便是雅典间谍送回的一份情报,它告诉雅典,波斯军队准备在斯巴达军队发起最后攻击时,突然对斯巴达军队进行袭击。斯巴达军队根据这份情报马上改变了作战计划,先以迅雷不及掩耳之势攻击毫无防备的波斯军队,并一举将它击溃,解除了后顾之忧。随后,斯巴达军队回师征伐雅典,终于取得了战争的最后胜利。

Bitcoin Cash trades on digital currency exchanges including Bitstamp,[30] Coinbase,[31] Gemini,[32] Kraken,[33] Bitfinex, and ShapeShift using the Bitcoin Cash name and the BCH ticker symbol for the cryptocurrency. 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]

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.

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."

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.[16]

“The arguments have devolved over three or four years of bitter debate, the principles are real and they are important to preserve, but a lot of the drama has nothing to do with principles anymore. A lot of this debate is now more about hurt feelings. It’s about bruised egos. It’s about things that were said that can’t be unsaid, insults that were exchanged, and personalities and ego.”

  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。

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.

There are two factions of bitcoin supporters, that support large blocks or small blocks.[20] 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.[20] 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.[20]
