FAQ & Guides Questions and educational content relevant to the Cosmos Hub. Announcements Announcements relevant to the Cosmos Hub. Validator Profiles Validators run the blockchain’s software (for Cosmos Hub this is in the Gaia repository) to produce and verify new blocks. You can find a list of all of the current Cosmos Hub validators using a block explorer like Mintscan. Validators guarantee security to the blockchain network by “staking”, i.e., putting up their own ATOM or ATOM that has been delegated to them, to produce or verify blocks. If they incorrectly verify a block (by signing the same block twice) or fail to produce blocks (by going offline), they are “slashed” for their misbehavior. In return for correctly verifying and producing blocks, they receive block rewards.
