Abstract

The categories of popular consensus punctures are reviewed: Proof of Work and its hybrids, Proof of Stake (includes LPoS, Proof of Importance) and hybrids, DAGs and its varieties. The article describes their algorithms, characteristics, features, as well as disadvantages and advantages. Vulnerabilities and attacks are subject to. Also provides a list of the use of each protocol in cryptocurrencies and other systems.
