NEXART EVIDENCE BRIDGE

Turn existing execution data into verifiable evidence.

Evidence Bridge maps your existing JSON or OpenTelemetry execution data into NexArt Certified Execution Records without requiring you to redesign your application payloads.

Use deterministic mapping to select the evidence that matters, review exactly what will be certified, create a cryptographically protected CER, verify it locally, and optionally submit it to the NexArt Node for independent attestation.

A CLEAR, REVIEWABLE PATH

From existing data to verifiable evidence.

  1. 01Existing JSON or OpenTelemetry
  2. 02Deterministic mapping
  3. 03Review evidence + disclosure
  4. 04Certified Execution Record
  5. 05Local verification
  6. 06Optional NexArt Node attestation
TRUST BOUNDARY

Built for evidence, not observability

Evidence Bridge does not replace your logs, traces or monitoring. It converts selected execution data into independently verifiable evidence with deterministic transformation provenance and cryptographic integrity.

It can prove that the certified record has not been altered. It does not prove that the original source claims were true, complete or correct.

EVIDENCE BRIDGE / OVERVIEW

Turn the JSON you already produce into verifiable execution evidence.

NexArt Evidence Bridge applies a published deterministic mapping profile to your application's existing JSON, creates and locally verifies structured NexArt execution evidence, and can optionally submit the unchanged evidence for separate NexArt Node attestation.

Trust boundary Bridge verifies the integrity of the transformation and preserves mapping provenance. It does not independently prove the truth or completeness of the source event.

MAPPING PROFILES / CREATE

Define a truthful transformation.

Published revisions are immutable. Changes create a new revision linked to its exact profile hash.

The source preset controls only deterministic Auto-map aliases. It does not change the evidence type or runtime endpoint.

Mapping and evidence outcomes remain separate. No single badge represents the entire trust state.

PUBLIC MAPPED REPRESENTATION

Confidentiality-safe mapped view

Protected values are hidden here after confidential evidence is created. Their mappings remain visible in Origin Trace, while the CER contains cryptographic commitments for those fields.

ORIGIN TRACE

Where each field came from

Origin Trace shows where each evidence field came from in the source JSON. Protected values may not appear in the public mapped representation after confidential sealing.

EVIDENCE STATUS

Independent status signals

Each signal answers a separate question. No single status represents the complete trust state.

Mapping validThe configured transformation completed successfully.
Evidence eligibleThe mapped event contains the semantics required by the selected evidence target.
Preview CER createdA local preview evidence artifact was generated.
Locally verifiedThe generated evidence passed its corresponding local integrity verification.
Node attestedA separate NexArt Node attestation exists.
Independent timestampExternal timestamp evidence has been independently verified where applicable.

INTEGRATION

Send the JSON you already produce.

The mapping profile performs the deterministic transformation at the current host. No manual CER creation is required.
