On-Chain Data Query

Definition

An on-chain data query is a request to retrieve specific information directly from a blockchain’s public ledger. This process involves extracting verifiable transaction details, smart contract states, or other publicly recorded information directly from a blockchain network. Unlike off-chain data, on-chain data is immutable and transparent, providing a definitive record of events and asset movements. Queries can be executed using blockchain explorers, specialized APIs, or by directly interacting with network nodes.
