A Data Fidelity Register is a set of an organisation’s facts, each one bound to its public source and sealed so it can be checked.
Below is a single entry, shown to make the shape plain. A register is many of these, published together on the organisation’s own domain.
The company name is masked here; this entry illustrates the structure, not a live record. The seal is a SHA-256 fingerprint over the fact’s six fields, so any later change to the value, the period, the quote or the source is detectable. Every fact in a register carries one.
The facts in a release are sealed together, and the release itself is anchored so the whole set is tamper-evident:
The individual seals are combined into a single fingerprint, the release commitment, using a Merkle tree, and that commitment is signed and entered in a public log. Anyone can confirm the entry exists in the log independently of Apparat. This is what lets a register be trusted without trusting us.
