AI Action Receipts: seal the HASHES of an AI action (input/output as hashes; your action label + meta are published) into GBLIN's signed append-only transparency log. Portable receipt: Ed25519 signature + RFC 6962 inclusion proof + C2SP signed checkpoint; root anchored daily on Base (EAS). Proves existence and time — not a compliance certificate. Free reads + demo: gblin-mcp.gblin-mcp-worker.worke
