Blockchain Validator Guide

When working with blockchain validator, a node that proposes and finalizes blocks in a proof‑of‑stake network. Also known as validator, it is the engine that keeps the ledger honest.

In a proof‑of‑stake, participants lock up tokens to earn the right to validate transactions, the validator node must meet hardware and uptime requirements. This validator node, the physical or virtual server running the consensus client handles block proposals, votes on finality, and manages keys securely. The amount of staking rewards, the income earned for successful block validation directly influences a validator’s economics, encouraging reliable uptime and penalizing misbehavior. Together, these pieces enable the broader consensus mechanism, the set of rules that determine how a blockchain reaches agreement that powers most modern PoS chains.
