$ETH MINER

In a Proof of Work blockchain (like Bitcoin), miners use computational power to solve complex cryptographic puzzles. This secures the network, verifies transactions, and adds new blocks to the blockchain. Miners who succeed in solving these puzzles earn rewards for their work.

NODE

A node is any computer or server connected to a blockchain network. It stores a full or partial copy of the blockchain ledger, validates transactions and blocks, and shares information across the network. Nodes are essential for maintaining the decentralization and security of the blockchain.

VALIDATOR

In a Proof of Stake blockchain, validators are selected based on the amount of cryptocurrency they commit ("stake") to the network. Validators confirm transactions and propose new blocks—similar to miners, but without the need for heavy computing power. Honest validators are rewarded for their participation.
