A cryptographic validator is a participant in a blockchain network responsible for confirming and validating transactions. These validators play a crucial role in ensuring the integrity and security of the blockchain.In proof-of-stake systems, validators are chosen based on the amount of cryptocurrency they hold and are willing to “stake” as collateral. When a validator is selected, they review and confirm transactions, adding them to the blockchain. They are rewarded with transaction fees and new coins for their work.Validators must maintain honest behavior. If they act maliciously or fail to validate accurately, they can lose their staked coins. This mechanism encourages good practices among participants.In proof-of-work systems, the process involves miners instead of validators, but the goals are similar: to secure the network and validate transactions. Both mechanisms aim to ensure that transactions are genuine and that the blockchain remains trustworthy.
