How digital currency works

新用户所需了解的基本知识

作为新用户，你可以开始使用数字货币，而不需要理解其中的技术细节，一旦你在电脑或手机上安装一个数字货币钱包，它会生成你的第一个虚拟币地址，并且在你需要的任何时候都可以生成更多的地址。你可以将你的地址告诉你的朋友们，他们便能够通过这个地址向你支付数字货币，反之亦然，事实上，这跟电子邮件的运作方式是非常相似的，除了一个数字货币地址应该只被使用一次。

余额 - 区块链

区块链是整个数字货币网络所依赖的公共共享总帐，所有确认的交易均包含在区块链中。这样数字货币钱包可以计算出可用余额，并核实新的交易中消费方花费的确实是自己的数字货币，密码学确保了区块链的完整性和时间顺序。

交易 - 私钥

一笔交易是指包含在区块链里的数字货币钱包之间的价值转移。数字货币钱包保存着一份称作私钥或种子的保密数据用来为交易签名，即提供数学证据证明这些交易来自钱包的拥有者。这个签名也确保交易发生后不会被任何人修改。所有的交易在用户之间广播，通常在接下来的10-20分钟内通过一个称作挖矿的处理过程开始被数字货币网络所确认。

处理- 挖矿

挖矿是个将待确认的交易数据包含到区块链中，从而完成对这些交易进行确认的分布式共识系统。通过挖矿，可以强制性保证块链中的数据按时间顺序存储，保持数字货币网络的中立性，且允许数字货币网络上不同的计算机对系统状态达成一致。交易要获得确认，必须要被打包到一个符合非常严格的密码学规则的区块中，并通过数字货币网络进行验证。这些规则可以防止对已有块的修改，因为一旦有改动，之后所有的块都将失效。挖矿的难度和中彩票相当，没人可以轻易地、连续地将新块加入到块链中。因此，没有集体和个人可以控制块链中包含什么样的内容或者替换掉块链中的部分内容以达到撤销他们交易的目的。

Basic knowledge that new users need to know

As a new user, you can start using digital currency without understanding the technical details. Once you install a digital currency wallet on your computer or mobile phone, it will generate your first virtual currency address, and when you need it more addresses can be generated at any time. You can tell your friends your address, and they will be able to pay you digital currency through this address, and vice versa. In fact, this is very similar to how email works, except for a digital currency address, should only be used once。

Balance - Blockchain

The blockchain is a public common ledger on which the entire digital currency network depends, and all confirmed transactions are included in the blockchain. In this way, the digital currency wallet can calculate the available balance and verify that what the consumer spends in the new transaction is indeed their own digital currency. Cryptography ensures the integrity and time sequence of the blockchain。

Transaction - Private Key

A transaction refers to the transfer of value between digital currency wallets contained in the blockchain. Digital currency wallets store a secret data called a private key or seed to sign transactions, that is, to provide mathematical proof that these transactions come from the wallet owner. This signature also ensures that the transaction will not be modified by anyone after the transaction occurs. All transactions are broadcast between users, usually in the next 10-20 minutes through a process called mining, which is confirmed by the digital currency network。

Processing - Mining

Mining is a decentralized consensus system that includes transaction data to be confirmed in the blockchain to complete the confirmation of these transactions. Through mining, it is mandatory to ensure that the data in the block chain are stored in chronological order, maintain the neutrality of the digital currency network, and allow different computers on the digital currency network to agree on the state of the system. In order for a transaction to be confirmed, it must be packaged in a block that complies with very strict cryptographic rules and verified through a digital currency network. These rules can prevent the modification of existing blocks, because once there is a change, all blocks will be invalid afterwards. The difficulty of mining is comparable to that of winning a lottery, and no one can easily and continuously add new blocks to the block chain. Therefore, no collective or individual can control what kind of content is contained in the block chain or replace part of the content in the block chain to achieve the purpose of revoking their transactions。
