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.
