The advent of the Bitcoin system has brought another boom in Internet era. In a very short time, many Blockchain systems come into being successively, whose decentration, consensus mechanisms, intelligent contract, and other characteristics make them applicable to various fields such as finance, education, medical, technology, etc. mechanism is core technology. And good plays important role stable operation system. continuous improvement mechanisms PoW (proof-of-work), PoS (proof-of-stake), DPoS (delegated-proof-of-stake), PBFT (Practical Byzantine Fault Tolerance) led evolution technology 3.0. Starting from issue generals, this article analyzes common based on existing applications then evaluates their consistency. This paper unique perspective, selection comment latest progress literature field block chain. At last, it also high degree summary prospect problems future development trend.
