How verification works

  1. Every SIGIL is Ed25519-signed by the sovereign root key d75a9801...a8f3
  2. Every SIGIL is SHA-256 chained to the prior SIGIL
  3. Every block is OTS Bitcoin-anchored via OpenTimestamps
  4. Verification checks: (a) Ed25519 signature valid, (b) SHA-256 chain intact, (c) OTS Bitcoin proof present
  5. If all 3 pass: artifact is verified as sovereign-issued
Honesty register: This page is a DEMO. The current SIGIL chain is local-only (queued because Vercel edge network is reachable but VM is offline). Real verification requires: (1) live SOV3 endpoint at localhost:3101/mcp (VM-side), (2) OTS Bitcoin anchoring service (owner-gated), (3) Charter Article 0 binding on every action. Charter Article 0 binding applies to all.
