Validator Requirements

Definition ∞ Validator Requirements refer to the specific criteria and technical specifications that an entity must satisfy to operate as a validator node within a proof-of-stake or similar consensus-based blockchain network. These requirements typically include minimum stake amounts, hardware specifications, uptime guarantees, and adherence to network rules. Meeting these criteria is essential for participating in block production and transaction verification. They ensure the network’s security and operational integrity.
Context ∞ Discussions around Validator Requirements are prominent in news concerning proof-of-stake blockchains, particularly regarding network decentralization and potential centralization risks if requirements are too high. The balance between maintaining network security through stringent requirements and promoting broad participation is a continuous debate. Future protocol upgrades often adjust these requirements to optimize for both performance and distributed control.
