Verifiable evidence

Runnable proof — three live L12 chains.

Every claim Promethean makes about "cryptographically auditable AI" is backed by code anyone can run. Below: three example chains, one per reference deployment (paysafe / cliniclens / civicgate). Download the chain. Download the Apache-2.0 verifier. Run. The verifier is ~500 lines of plain Node 18+, zero npm dependencies.

30-second verification

  1. # 1. fetch the verifier
    curl -O https://promethean.software/verify.mjs
  2. # 2. fetch any example chain
    curl -O https://promethean.software/paysafe-runtime-ai-receipts.jsonl
  3. # 3. verify
    node verify.mjs paysafe-runtime-ai-receipts.jsonl

Expected: PASS (exit 0) with a breakdown of every model identity, schema-violation count, reviewer verdict, and per-entry signature status. If the chain has been tampered with, FAIL with the entry id and reason.
