Several common consensus mechanisms (pbft,raft,pow,pos,dpos,ripple) in blockchain have been summarized in recent days. Try to use simple and understandable language, the space is large, want to understand can read each algorithm introduced in front

Virtual Agent Mode-virtual ProxyVirtual proxy mode defers the actual time required for object instantiation. If a proxy object can handle a real object before it needs to work, the real object is not needed for the moment.Pros: The advantage of this

Coordinated Universal time (UTC): Coordinated worlds, also known as World standard Times, is known as Greenwich Mean Time (Greenwich Mean time,gmt). For example, the time difference between the Chinese mainland and UTC is +8, which is utc+8. The

We describe the names of some standard signals and the events they represent. Each signal name is a macro that represents a positive integer, but you do not attempt to speculate on the exact value represented by the macro, but instead use the name

Description: People who like to write small programs pay special attention to the execution efficiency of their own programs, then on Linux, there is a time command to measure the runtime of the command, but also to measure the use of memory, I/O,
