Validator
By CoinGecko | Updated on Mar 03, 2020
In contrast to mining on a Proof of Work blockchain network, Proof of Stake blockchain networks are secured by a distributed consensus of dedicated validators who have staked (locked into the network) a significant amount of token as long as the validator nodes are running. Validators are queued for block-signing based on a cambination of random selection, amount (weight) staked and length of time staked (age) and others depending on the design of the consensus algorithm.
