About this register
This register publishes verified facts about OpenClassrooms, each drawn from a public source. Each fact is kept with its source, its verbatim context, and a cryptographic seal that lets anyone verify its integrity.
How it works
Each fact carries a SHA-256 seal computed over six fields: label, value, context, source URL, unit, and time period. The seals are combined into a single commitment, timestamped and anchored in a public transparency log (Sigstore Rekor, operated by the Linux Foundation). Any later change to an entry breaks its seal, so the register is tamper-evident and can be verified by anyone.

Apparat guarantees the fidelity of this register to its sources: each entry reflects the document it cites. Apparat does not audit the truth of the source documents themselves.
Independent verification
The format and its reference verifier are open: anyone can check the seals, the signature, and the anchoring without trusting Apparat. github.com/data-fidelity-register/verifier
