The Proof Fabric Architecture
How Proof Fabric Protocol is architected: issuers, proof artifacts, and verifiers — with no central authority in the verification path.
February 8, 2026
Three roles
The architecture has three roles. An issuer is a system that emits proofs, holding a signing key bound to an authorized identity. A proof artifact is the compact, signed record of an event. A verifier is anyone holding the artifact and the issuer’s public key.
Crucially, there is no shared database of secrets and no central authority that verification depends on. Verification is a local, mathematical operation.
Data stays at the edge
Sensitive data never enters a proof. Issuers commit to data with a hash at the moment of the event, so the raw data remains within the issuer’s control. This keeps the fabric privacy-preserving by design rather than by policy.
Portability and durability
Because artifacts are self-contained and self-verifying, they can be stored anywhere and remain verifiable long after the originating system changes or goes offline. This makes the fabric durable and suitable for long-lived evidence.
Key takeaways
- Roles: issuer, proof artifact, verifier — no central authority in the path.
- Sensitive data stays at the edge; only commitments travel.
- Artifacts are portable and remain verifiable over time.
