Constant Committee Size

Definition ∞ Constant committee size refers to a fixed number of participants responsible for specific tasks in a decentralized network. This architectural choice in blockchain protocols means the group of validators or nodes responsible for block production or transaction verification maintains an unchanging member count. Such a design aims to provide predictable security assurances and consistent network performance. It contrasts with dynamic committee structures where membership can vary, often balancing decentralization with efficiency considerations.
Context ∞ Discussions around constant committee size frequently arise in sharding implementations and proof-of-stake systems, where maintaining security against malicious actors is paramount. Its selection often represents a trade-off between network scalability and the overhead associated with committee management. Future protocol upgrades often consider how to maintain security guarantees while potentially adjusting committee dynamics.
