Proof of Stake

Page Summary

Proof of Stake is a consensus mechanism for blockchain technologies. It works by selecting validators according to the quantity of cryptocurrency they hold. Every blockchain uses a consensus mechanism to keep its network safe. It is difficult for attackers to get more than 51% of a cryptocurrency. For this reason, they cannot easily take over a Proof of Stake network. Proof of Stake is different from Proof of Work, in which miners validate transactions. The first Proof of Stake cryptocurrency was Peercoin.
