比特币是如何运作的？ 6 W3 }& D/ K a) I, @' H
% N7 @/ w' L4 g- f6 C+ h
) ]2 S* [- g( X0 h2 r: t
从用户的角度来看，比特币就是一个手机应用或电脑程序，一个比特币钱包。用户可以用它支付和接收比特币。这就是比特币对于大多数用户的运作原理。在幕后，整个比特币网络共享一个称作“区块链”的公共账本。
6 ]/ L/ b* A5 R6 g/ ^" u! M6 q p N* S' a2 X
如果我们把比特币区块链类比成一个实物账本，那么每个区块就相当于这个账本中的一页，每十分钟生成一页新的账本，每一页账本上记载着比特币网络这十分钟的交易信息。每个区块之间依据密码学原理，按照时间顺序依次相连，形成链状结构。 所以这份账本包含了每一笔处理过的交易，使得用户的电脑可以核实每一笔交易的有效性。每一笔交易的真实性由发送地址对应的电子签名保护。 * v- `3 S4 }% k$ l% J
# S% C' n- T* l" d 另外，任何人都可以利用专门计算设备来处理、记录交易并获得比特币奖励。这一服务经常被称作“挖矿”。通过挖矿，调动了挖矿者（矿工）的积极性，还保证了交易的确认速度、交易记录的正确性及比特币网络的安全性。
5 X4 X0 C/ | t$ G2 i4 v. G0 Y' g
, l: A F. W K+ X$ e% N 没有谁拥有比特币网络，就像没有人拥有电子邮件背后的技术一样。比特币由世界各地所有的比特币用户控制。开发者可以改善比特币钱包软件，但他们不能强行改变比特币协议的规则，因为所有的用户都可以自由选择他们想用的钱包软件。, ?/ b! ?- _" Z4 ]
# D3 L& L3 Z+ j( _
为了相互之间保持兼容性，所有用户也需要选择遵循相同规则的钱包软件。只有所有用户达成完全一致的共识，比特币才能正常地工作。因此，所有的用户和开发者对接受和保护这一共识很有动力.
