On-chain monitoring is the continuous observation and analysis of transactions and activities recorded directly on a blockchain ledger. This practice involves utilizing specialized tools and algorithms to track, decode, and interpret data publicly available on distributed ledgers, such as transaction volumes, address activity, smart contract interactions, and token movements. It provides real-time insights into network health, user behavior, and potential security threats or illicit activities. The immutable nature of blockchain data makes this form of surveillance highly accurate and verifiable.
