Validator News
A validator is a person or entity in charge of verifying blockchain transactions. Transactions are added to the distributed ledger after the blockchain validator has gone through the official process of validating them.
In systems using the proof-of-work (PoW) algorithm, such as Bitcoin, miners (acting as validators) solve challenging computational arithmetic problems to earn the ability to validate transactions and collect rewards for their work. On the other hand, in proof-of-stake (PoS) systems, validators receive incentives when they stake the network’s token and correctly engage with the network, such as with Avalanche and its AVAX token. By requiring value to be locked up in the network to take part in the consensus decisions, this approach aids in network security.
In the PoS version of Ethereum, a validator on the Beacon Chain participates in Ethereum network consensus and is represented by a balance, public key and other features. The validators must stake at least 32 ETH to participate in the validation process. However, they can use pooled staking services if they don’t have 32 ETH but still want to earn block rewards by properly batching transactions into new blocks.
