Blockchain
A blockchain is a decentralized digital ledger that records transactions in blocks, links those blocks together, and makes the record difficult to alter.

A validator is a network participant in a Proof-of-Stake (PoS) blockchain that stakes cryptocurrency to propose, verify, and finalize new blocks of transactions, earning rewards for honest behavior and risking penalties (slashing) for misconduct.
