Network Validators

Definition ∞ Network validators are participants in a blockchain network responsible for verifying transactions and maintaining the integrity of the distributed ledger. In proof-of-stake systems, validators stake their digital assets as collateral to participate in the consensus mechanism. They are rewarded for honest behavior and penalized for malicious actions. These entities are fundamental to the security and operation of many modern blockchains.
Context ∞ Network validators are frequently discussed in crypto news, especially concerning blockchain upgrades, decentralization efforts, and staking economics. Reports often cover the distribution of validation power, the rewards offered, and the technical requirements for participation. Debates sometimes arise regarding the concentration of validators and its implications for network censorship resistance. Their role is central to the ongoing evolution and security of various proof-of-stake protocols.
