Onchain Event

Definition ∞ An onchain event is any action or transaction that is recorded permanently on a blockchain. This refers to verifiable activities such as token transfers, smart contract executions, or protocol upgrades, all of which are immutable and publicly accessible on the distributed ledger. These events form the fundamental data points of any blockchain network. They provide transparent proof of state changes and interactions within a decentralized system.
Context ∞ Onchain events are crucial metrics for analyzing the activity and health of various blockchain networks and decentralized applications. Analysts frequently monitor transaction counts, gas usage, and smart contract interactions to gauge network utility and user engagement. Significant onchain events, like large token movements or major protocol changes, often correlate with market sentiment and news cycles.
