戳记

将该戳记与其他所有人为相同的资源在同一日期生成的戳记区别开来的随机因子（salt）。

A random salt that distinguished this stamp from any other one minted for the same resource and date .

对那些没有添加hashcash戳记的发送者而言，检验X-Hashcash：的接收者不用校验任何内容。

For senders who do not add hashcash stamps , recipients who check for X-Hashcash : just do not have anything to check .

即使垃圾邮件制造者利用植入木马（trojans）的僵尸（zombies）的技术，需要使用具体的hashcash戳记至少也会减少那些僵尸进程的发出量。

Even if spammers utilize zombie machines they have infected with trojans , requiring individualized hashcash stamps at least slows down the traffic out of those zombies .

例如，一个快速的PentiumIII或者G4可以在不到一秒钟之内生成一个20-比特的戳记，但是Pentium-II或者G3做不到。

For example , a fast Pentium III or slow G4 can mint a20-bit stamp in less than a second , but a Pentium-II or G3 cannot .

hashcash提出质询的方式是，当通过安全散列算法（SecureHashAlgorithm）进行散列时，要求“minters”生成一个字符串（戳记，stamps），在它们的散列中有很多前导零。

The way hashcash poses a challenge is by asking " minters " to produce strings ( stamps ) that when hashed with the Secure Hash Algorithm , SHA-1 , have a number of leading zeros in their hash .

给定SHA-1的一致性与加密强度，找出给定比特值的hashcash戳记的惟一已知途径是平均2^b次运行SHA-1。

Given the uniformity and cryptographic strength of SHA-1 , the only known way to discover a hashcash stamp of a given bit value b is by running SHA-12 ^ b times on average .

假定给出了前6个域，为了生成一个通过期望数目的前导零进行散列的的戳记，minter必须尝试很多连续的后缀值。

Given the first six fields , a minter must try many sequential suffix values to produce a stamp that hashes with the desired number of leading zeros .

生成戳记的日期（和时间）。

The date ( and time ) a stamp was minted .

This is checked based on the timestamp of the last time check .

你从图书馆借的书上的戳记表明，这本书必须明天归还。

The stamp in your library book shows it must be returned tomorrow .

用户可能会决定认为比特定期限更早的戳记是非法的。

A user may decide to consider stamps older than a certain age invalid .

所找到的前导零的数目就是特定戳记的比特值。

The number of leading zeros discovered is the bit value of a particular stamp .

现在面临的挑战是如何获得更多可以更无缝地处理bashcash戳记的工具。

The challenge now is to get more tools to process hashcash stamps more seamlessly .

附加的时间戳记对于是否是当前状态是很重要的。

The addition of the date-time stamp is important to give a sense of currency .

当然，校验一个戳记所需的时间只是一秒的一小部分。

Checking a stamp , of course , takes a tiny fraction of a second .
