Description: A passive validator is a component within proof-of-stake (PoS) systems that does not actively engage in the transaction validation process. Instead, this type of validator relies on other validators to carry out the verification and consensus of transactions on the network. This approach allows passive validators to participate in the blockchain ecosystem without the need to maintain complex technical infrastructure or be constantly online. Passive validators can delegate their participation to active validators, who are responsible for validation and network maintenance. This dynamic promotes decentralization and security, as it enables more users to get involved in the validation process without requiring a high level of technical knowledge. Additionally, passive validators can receive rewards for their participation, although their role is more limited compared to active validators. In summary, passive validators are an integral part of proof-of-stake systems, facilitating the inclusion of a larger number of participants in the consensus process and contributing to the robustness of the network.
