# The responsibility of validator Validators have two main responsibilities: * Validators ensure that their servers are always online and private keys are not compromised. * Actively participate in the consensus process: Validators are required to vote, commit new blocks in the blockchain. Additionally, validators are expected to be active members in the community. They are always updated with the current state of the system. Validators play a special role in the system because they are required to vote on every proposal. --- # 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.
