Introduction
Proof of Stake (PoS) is a consensus mechanism used by various blockchain networks to validate transactions and secure the network. It was developed as an energy-efficient alternative to the Proof of Work (PoW) mechanism, primarily pioneered by development on the Tendermint Consensus mechanism for Cosmos chains back in 2013-2014. In PoS, validators are chosen to create new blocks and confirm transactions based on the amount of cryptocurrency they lock up, or “stake,” in the network.
