Did you know that some tech giants are now blockchain validators? Google Cloud, for instance, is a validator for several blockchains, including Celo and Polygon.
A blockchain validator is a network participant that helps to maintain the blockchain's integrity and security.
The primary role of a blockchain validator is to verify and validate new transactions and blocks, particularly in Proof-of-Stake (PoS) networks like Ethereum, etc.
To validate a transaction, validators must first ensure that the transaction adheres to the network's rules, such as confirming that the sender has sufficient funds and that the transaction is not fraudulent.
After that stage, the validator now works with other validators to agree on which transactions are valid and which blocks should be added to the chain.
If the transaction passes all the checks, then it would be considered valid and mapped on the blockchain.
In essence, blockchain validators are the guardians of the network, ensuring that transactions are valid and that the blockchain remains secure and reliable.
