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

In a blockchain, data is stored as blocks, which are linked together in a chain. Each block contains a set of transactions or other data and 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.
