A blockchain validator is a member of a Proof-of-Stake blockchain network and its responsibilities usually include confirming transactions on a blockchain and adding them into the ledger; validators also have the duty of protecting the network’s integrity by validating transactions, making sure they respect by the network’s policies and procedures, and stopping fraudulent transactions.
For a large blockchain systems like Bitcoin or Ethereum, there are thousands of these kind of nodes or validators, that are consist mostly of volunteers who usually use their personal computers for the tasks.
Understanding of Blockchain Validator
Types of Blockchain Validators:
- Proof-of-Work Validators – one of the most expensive types of validators, require to solve complex mathematical problems to validate transactions; mostly used by Bitcoin
- Proof-of-Stake Validators – PoS validators are rewarded with the coins when they approve transactions and upload them to the blockchain; mostly used by Ethereum
- Delegated Proof-of-StakeValidators – token holders choose these validators, who then approve transactions and add them to the blockchain; mostly used by EOS
Three tasks are usually carried out by validator nodes:
- Verifying that new transactions are formatted correctly
- Calculating hash fingerprints from block to block to make sure no changes have been made to the chain
- Validating each new block to ensure that the miner’s puzzle was solved correctly and the block is correctly structured
