Validator Network

Definition ∞ A validator network comprises a group of participants responsible for verifying transactions and maintaining the integrity of a blockchain. These nodes confirm new blocks and ensure adherence to the protocol’s rules, typically in proof-of-stake or delegated proof-of-stake systems. Validators often stake cryptocurrency as collateral and receive rewards for honest participation. Their collective operation secures the network against malicious activity.
Context ∞ News about validator networks frequently discusses their role in blockchain security, decentralization, and the efficiency of consensus mechanisms. A key debate involves balancing the number of validators for security with the potential for centralization if too few entities hold significant stake. Future developments will focus on increasing validator participation, improving network resilience, and enhancing the economic incentives for honest operation.
