Validators

Definition ∞ Validators are entities responsible for confirming transactions and adding new blocks to a blockchain, particularly within Proof-of-Stake (PoS) consensus mechanisms. They are typically required to stake a quantity of the network’s native cryptocurrency as collateral, which incentivizes honest participation. Their involvement is essential for maintaining network security, integrity, and the finality of transactions.
Context ∞ The operational integrity and economic incentives of validators are fundamental to the security and performance of Proof-of-Stake blockchains. Current discussions frequently address validator performance metrics, the application of slashing penalties for malicious conduct, the distribution of staking rewards, and the potential for validator centralization to affect network decentralization and censorship resistance.
