On-Chain

On-chain refers to any transaction or data that is directly recorded and validated on the blockchain. On-chain transactions are visible, transparent, and immutable, meaning they cannot be altered once confirmed. On-chain operations are usually slower and more expensive compared to off-chain alternatives because they require network consensus and often include fees for miners or validators to process the transactions. Every transaction or action is part of the public ledger, contributing to the overall security and decentralization of the blockchain network. An example of on-chain transactions includes sending Ether (ETH) from one wallet to another, which gets recorded permanently on the Ethereum blockchain.
