A public validator is a participant in a blockchain network that helps secure and maintain the network by validating transactions. These validators are responsible for confirming the legitimacy of transactions and adding them to the blockchain.In networks that use proof-of-stake or similar consensus mechanisms, anyone can become a public validator by staking a certain amount of cryptocurrency as collateral. This means that they have a vested interest in the network’s health and integrity. By validating blocks of transactions, they earn rewards, typically in the form of the network’s native currency.Public validators play a crucial role in decentralization. Their participation helps ensure that no single entity has control over the network, promoting a more transparent and secure environment for all users. This setup encourages honest behavior, as malicious activity could lead to financial loss for the validator.Overall, public validators contribute significantly to the stability and reliability of blockchain networks, making them essential for the overall functionality of decentralized systems.
