作为新用户，你可以开始使用比特币，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比特币钱包，它会生成你的第一个比特币地址，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比特币，反之亦然。事实上，这跟电子邮件的运作方式是非常相似的，除了一个比特币地址应该只被使用一次。
As a new user, you can start using bitcoin without having to understand the technical details. Once you install a bitcoin wallet on your computer or cell phone, it will generate your first bitcoin address and more addresses whenever you need it. You can tell your friends your address, and they can pay you bitcoin through this address, and vice versa. In fact, this is very similar to the way e-mail works, except that a bitcoin address should be used only once.
比特币区块链是整个比特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。这样比特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比特币。密码学确保了区块链的完整性和时间顺序。
The bitcoin block chain is the public shared ledger on which the entire bitcoin network relies. All confirmed transactions are included in the block chain. This allows the bitcoin wallet to calculate the available balance and verify that the consumer spends its own bitcoin in the new transaction.
一笔交易是指包含在区块链里的比特币钱包之间的价值转移。 比特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比特币网络所确认。
A transaction is a transfer of value between bitcoins’ wallets, which are contained in the block chain. Bitcoins’ wallets are used to keep a confidential data file called private keys or seeds for the signature of the transaction, that is, to provide mathematical evidence that the transaction originated from the owner of the wallet. This signature also ensures that the transaction will not be modified by anyone after it has occurred.
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，保持比特币网络的中立性，且允许比特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，并通过比特币网络进行验证。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。
Mining is a distributional consensus system that incorporates the transaction data to be confirmed into the block chain, thus completing the identification of these transactions. By mining, data in the block chain can be stored in chronological order, maintaining the neutrality of the Bitcoin network and allowing different computers on the Bitcoin network to agree on the system's state. To be confirmed, the transaction must be packaged into a block that meets very strict cryptography rules and validated through the Bitcoin network. These rules prevent modification of existing blocks, since all blocks will lapse as soon as changes are made. The difficulty and the median lotteries are comparable, and no one can easily and continuously add new pieces to the chain. Therefore, there is no group or individual who can control what is contained in the chain or replace parts of the chain for the purpose of cancelling their transactions.
