Validator Selection Policy

Definition ∞ A Validator Selection Policy is the predefined set of rules and algorithms that determine which network participants are chosen to validate transactions and propose new blocks in a proof-of-stake blockchain. This policy governs the eligibility criteria, the method of selection, and the frequency of participation for validators. Its design directly impacts the decentralization, security, and performance of the network. A robust policy is essential for preventing collusion and ensuring network integrity.
Context ∞ The efficacy of a Validator Selection Policy is a central topic in the ongoing development and evaluation of proof-of-stake protocols. A key discussion involves balancing the desire for broad participation with the need for efficient and secure block production. Future developments are exploring more sophisticated randomization techniques and reputation-based mechanisms to enhance fairness and resistance to stake concentration.
