Fixed committee size refers to a design parameter in some decentralized systems where the number of participants in a governing or operational committee remains constant. This predetermined quantity of members provides a stable and predictable structure for decision-making or task execution. It simplifies network design and can aid in performance optimization. This approach contrasts with dynamic committee sizes that adjust based on network conditions.
Context
In proof-of-stake networks, fixed committee size is often chosen to provide a consistent level of security and decentralization. The discussion frequently centers on finding the optimal size to balance network overhead with resilience against malicious actors. Regulatory bodies may also scrutinize committee structures, assessing their governance and accountability implications.
By replacing probabilistic committee selection with deterministic bounds, this new sortition mechanism guarantees an honest majority, enhancing consensus security and network scalability.
A new cryptographic sortition method achieves deterministic bounds on adversarial committee influence, fundamentally enhancing Proof-of-Stake security and decentralization.
A new cryptographic sortition model introduces deterministic bounds on adversarial committee influence, enabling smaller, more efficient, and verifiably secure consensus groups.
