Definition ∞ A verifier committee is a group of participants within a blockchain network responsible for confirming the validity of transactions and blocks proposed by others. In certain proof-of-stake or delegated proof-of-stake systems, these committees are randomly selected or elected to perform crucial validation tasks. Their collective agreement ensures the integrity and security of the distributed ledger. This mechanism reduces the computational burden on individual nodes.
Context ∞ Verifier committees are often discussed in crypto news concerning the scalability and decentralization of various blockchain protocols. Reports may highlight the efficiency of these committees in processing transactions or their role in securing sidechains and layer-2 solutions. The design and implementation of effective verifier committees are critical for maintaining network security while improving transaction throughput in advanced blockchain architectures.
