OpenProof is the probative infrastructure. TruthX Engine is the deterministic structuring engine powering it. RPO is the Registered Probative Object it produces.
This repository provides a public reference implementation of the Registered Probative Object (RPO) specification.
It shows how fragmented evidence can be represented as a structured, traceable and machine-verifiable record for human review.
| Component | Role |
|---|---|
| TruthX Engine | Structures heterogeneous evidence through a controlled, deterministic pipeline. |
| RPO | Preserves the resulting record, its sources, transformations, reservations and integrity data. |
| OpenProof | Provides the probative infrastructure and verification layer. |
Processing chain:
Evidence → TruthX Engine → RPO → OpenProof validation
The reference implementation illustrates:
- the minimum structure of an RPO bundle;
- deterministic serialization of the record;
- generation of a reproducible integrity hash;
- detection of subsequent modifications;
- separation between machine-verifiable data and human-readable content.
The file example-bundle.json provides a minimal example.
For the same normalized input, a compliant implementation must produce the same sealed representation and the same integrity hash.
Any later modification to the protected content must be detectable.
The canonical public RPO specification is maintained here:
This repository implements and illustrates that specification. It does not replace it.
This reference implementation can verify structural conformity and integrity.
It does not:
- determine whether an allegation is true;
- assess the legal weight of evidence;
- replace expert analysis or human judgment;
- make institutional, judicial or governance decisions.
Automation supports judgment. It does not replace authority or accountability.
- RPO Specification — canonical public specification.
- RPO Examples — example probative objects and use cases.
- OpenProof Validator — conformity and integrity validation tools.
