12.4 On-Chain Data Anchoring

Once validated, the data is committed to the blockchain in a structured format. This process is referred to as data anchoring, where a representation of the data—often in the form of hashes or structured records—is stored on-chain.

This ensures that:

• data becomes immutable once recorded

• it can be referenced by smart contracts

• historical data can be audited and verified

From a technical standpoint, this anchoring process enables developers to build contracts that rely on verifiable external inputs, rather than assumptions or manual updates.
