On-Chain Commitment

Definition ∞ An on-chain commitment refers to the act of recording data or a cryptographic hash of data onto a blockchain. This action establishes an immutable and publicly verifiable record, demonstrating a party’s dedication to a specific action or value at a particular time. It forms a verifiable anchor for off-chain processes.
Context ∞ On-chain commitments are fundamental to various blockchain applications, including layer-2 scaling solutions and decentralized identity systems. They provide a trust anchor, allowing participants to verify the integrity of off-chain computations or data without needing to store everything directly on the main chain, thereby improving efficiency and scalability.
