Comparison of Two Validator's Voting History

A blockchain validator is someone who is responsible for verifying transactions on a blockchain. Once transactions are verified, they are added to the distributed ledger. In proof of work (PoW) systems like Bitcoin, validators, also known as miners, solve complex computational math problems in order to win the right to verify transactions and receive rewards for the “work.” In proof of stake (PoS) systems like Terra, validators are given rewards as long as they stake the network’s token and correctly participate in the network. A validator also called a proposer is chosen to submit a new block of transactions. Validators vote in two rounds on whether they accept or reject the proposed block. If a block is rejected, a new proposer is selected and the process starts again, if accepted, the block is signed and added to the chain. The transaction fees from the block are distributed as staking rewards to validators and delegators. Proposers get rewarded extra for their participation.
