On-chain data refers to the data that is stored on a blockchain. A blockchain is a decentralized, distributed database that is used to record transactions or other types of data in a secure and transparent way.

In a blockchain, data is stored in the form of blocks, which are linked together in a chain. Each block contains a set of transactions or other data, as well as a cryptographic hash that links it to the previous block in the chain. This creates a tamper-evident record of all the data that has been recorded on the blockchain.
