# About Validators Chiliz Chain relies on the Proof of Staked Authority (PoSA) consensus mechanism, designed to ensure fast block times and cost-efficient transactions. Advanced security features, including double-sign detection and slashing mechanisms, maintain the integrity, stability, and finality of the chain. This consensus mechanism is primarily managed by two key roles: * the Validators, who are a critical part of the chain. They create and validate blocks in turns. * the Delegators, who allocate their CHZ to the validators' pools in order to participate in the governance of the chain and earn reward. In Chiliz Chain, there is a set maximum of block-creating validators. There can also be an unlimited amount of active validators which are not creating blocks, but are in the queue in case a block-creating validator goes offline or gets "jailed". --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
