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.
3.时间戳服务器
我们提供的解决方案从时间戳服务器说起。一个时间戳服务器是靠对多个项目组成的区块进行哈希来得到时间戳，并在如报纸或Usenet网广泛发布该哈希值而得以工作，时间戳证明数据在那个时间点一定是存在的，明显的，为了得到哈希值，每个时间戳的哈希值中都包含之前的时间戳，从而形成一条链，每一个新增的时间戳都对其上一个进行加强。
细节解读
What's "timestamp "
A timestamp is a sequence of characters or encoded information identifying when a certain event occurred, usually giving date and time of day, sometimes accurate to a small fraction of a second. The term derives from rubber stamps used in offices to stamp the current date, and sometimes time, in ink on paper documents, to record when the document was received. Common examples of this type of timestamp are a postmark on a letter or the "in" and "out" times on a time card.
In modern times usage of the term has expanded to refer to the digital date and time information attached to digital data. For example, computer files contain timestamps that tell when the file was last modified, and digital cameras add timestamps to the pictures they take, recording the date and time the picture was taken.
什么是时间戳
时间戳是一系列字符或编码信息，用于识别特定事件何时发生，通常给出日期和时间，有时精确到一小部分秒。 该术语来自办公室中使用的橡皮图章，用于标记当前日期，有时用墨水在纸质文件上记录，以记录收到文件的时间。 这种类型的时间戳的常见示例是字母上的邮戳或时间卡上的“ in”和“ out”时间。
在现代，该术语的使用已经扩展到指代附加到数字数据的数字日期和时间信息。 例如，计算机文件包含时间戳，用于指示文件上次修改的时间，数码相机为其拍摄的图片添加时间戳，记录拍摄照片的日期和时间。
