A node validator is a participant in a blockchain network responsible for verifying and validating transactions. These nodes maintain the integrity of the blockchain by ensuring that all transactions comply with the network’s rules.Validators are crucial in consensus mechanisms like Proof of Stake (PoS). Instead of relying on energy-intensive mining, validators are selected to create new blocks based on their stake in the network. They lock up a certain amount of cryptocurrency as collateral, which can be forfeited if they act maliciously or fail to validate properly.Being a node validator often requires technical knowledge and resources, such as a reliable server and internet connection. Validators typically earn rewards in the form of transaction fees or newly minted coins for their work, incentivizing them to act in the network’s best interest.In summary, node validators help secure and maintain the blockchain by validating transactions, contributing to the network’s overall trustworthiness and efficiency.
