众所周知,比特币网络是采用的P2P网络体系,所以,没有明显的客户端与服务端的区别或者是概念,每一个节点既是自身的客户端,又是其它节点的服务端。
在sync.h中,定义了 CSemaphore,它包装了系统底层的信号量机制,对wait(), try_wait(),post()实现了封装,代码如下:
1234567891011class CSemaphore..

如今,委内瑞拉的法币几乎一文不值,而且它的现金危机只会越来越糟糕。
在过去几个月里,我们看到这个国家陷入了越来越严重地一场全面的人道主义灾难中,“经济确实处于一个无解的螺旋式下降中”-Steve Hanke说,他是普金斯大学的应用经济学教授。
国家政策导致在过去一年多的时间里通货膨胀率上升了4115%,对应的玻利瓦尔(委内瑞拉货币)在2017年贬值了9..

go-ethereum中go-event库的使用github.com/ethereum/go-ethereum/event包实现了一个事件发布订阅的库,使用接口主要是event.Feed 类型,以前还有event.TypeMux 类型,看代码注释,说过时了,目前主要使用Feed 类型。
