David McNab created a Python implementation that does not use quite the same protocol as hashcash itself; some other developers have also created incomplete Python versions of parts of hashcash. 其他一些开发人员也创建了部分实现hashcash的不完全的Pytyhon版本。
Donald McNab, who was physically disabled and used a crutch, later described seeing men hammering away in desperation at glass windows with their bare hands. 唐纳德?麦克纳伯是一位使用拐杖的残疾人士,后来自己描述说他看到工人们绝望的徒手捶打玻璃窗。
