比特币白皮书解读（时间戳）

3. Timestamp Server

The solution we propose begins with a timestamp server. A timestamp server works by taking a hash of a block of items to be timestamped and widely publishing the hash, such as in a newspaper or Usenet post [2-5]. The timestamp proves that the data must have existed at the time, obviously, in order to get into the hash. Each timestamp includes the previous timestamp in its hash, forming a chain, with each additional timestamp reinforcing the ones before it.

我们提出的方案是以时间戳服务开始的

A timestamp server works by taking a hash of a block of items to be timestamped and widely publishing the hash, such as in a newspaper or Usenet post [2-5]. 

时间戳服务器通过对以区块形式存在的一组数据实施随机散列而加上时间戳，并将该随机散列进行广播，就像在新闻或世界性新闻组网络的发帖一样。

 The timestamp proves that the data must have existed at the time, obviously, in order to get into the hash.

显然，该时间戳能够证实特定数据必然于某特定时间是的确存在的，因为只有在该时刻存在了才能获取相应的随机散列值。

Each timestamp includes the previous timestamp in its hash, forming a chain, with each additional timestamp reinforcing the ones before it.

每个时间戳应当将前一个时间戳纳入其随机散列值中，每一个随后的时间戳都对之前的一个时间戳进行增强，这样就形成了一个链条。
