The Inner Workings of Proof-of-Stake Cryptocurrency

Proof-of-Stake (PoS) is a consensus mechanism used by some cryptocurrencies to secure their networks and validate transactions. Unlike the more commonly used proof-of-work (PoW) mechanism, where miners compete to solve complex mathematical problems in order to validate transactions and add new blocks to the blockchain, PoS relies on users holding a certain amount of the cryptocurrency to "stake" their coins and validate transactions.

The idea behind PoS is that users who have a vested interest in the network, and therefore have a stake in it, are more likely to act in the best interest of the network by validating transactions honestly. Additionally, PoS is generally considered to be more energy-efficient than PoW, as it does not require significant computational power to participate in the validation process.
​
One of the most notable cryptocurrencies that uses a PoS consensus mechanism is Ethereum, which transitioned from a PoW mechanism to a PoS mechanism called Ethereum 2.0. Other examples of PoS cryptocurrencies include Dash, Decred, and Nxt.
