A single synchronous call to DNR Verify runs the full pipeline under a strict latency budget. Any layer can approve, require step-up authentication, hold for review, or reject, all under rules the institution owns.
A chain adapter normalizes the transaction into a canonical schema and validates structure, asset, contract, and chain support, including finality semantics for the network involved.
Deterministic, versioned institution rules evaluate amount ceilings, velocity, allow and deny lists, destination checks, and approval requirements. Policy is the final authority in every verdict.
DNR Intelligence scores the transaction against behavioral and contextual features and returns a risk score with machine-readable reason codes and supporting evidence.
Where appropriate, verified credentials and institutional KYB evidence contribute additional signals to the decision.
The verdict is signed with a hybrid signature: classical Ed25519 plus NIST-standardized ML-DSA, so the record stays valid even if either scheme is later weakened.
A verifiable record naming the exact controls, policy version, and evidence hashes is written to an append-only, Merkle-anchored transparency log that anyone can independently check.
DNR never holds funds and never controls the keys that move value. It verifies flows it does not control. Independence is the source of its trust value.
AI produces scores and reasons; institution-owned rules decide the action. Explainable to regulators by construction, with no opaque automated authority.
On timeout, dependency failure, or ambiguity the secure default is hold or reject. A silent approval is treated as a defect of the highest severity.
Every verdict yields a signed record anchored in an append-only log. Any third party can verify what controls ran and what evidence was used.
Algorithms are referenced through a versioned registry, so schemes can rotate as standards evolve without breaking historical records.
Network-specific adapters normalize each blockchain into one canonical model. Assets stay on their existing networks; DNR adds a layer around them.
DNR builds on the NIST-finalized post-quantum standards: ML-KEM for key establishment, ML-DSA for signatures, and SLH-DSA for long-lived hash-based assurance. Hybrid signing keeps every attestation valid under both classical and post-quantum assumptions. DNR applies this to the layer it controls (authorization, attestation, and audit) and makes no claims about the underlying blockchains themselves. Read the full whitepaper for the complete design.
| Attribute | Target | How |
|---|---|---|
| Verify latency | p50 < 120ms · p99 < 300ms | Stateless sync path, budget split across layers |
