Hello, We would like our log added to the testing list. Origin line: gblin.digital/receipts-log Public key: gblin.digital/receipts-log+00c6e18c+AY8/YnCHXTnsECT2EGv0M5RTqlVvFobctLv3WSihYkoG Checkpoint: GET https://gblin-mcp.gblin-mcp-worker.workers.dev/log/checkpoint add-checkpoint rate: at most 24 times per day, in practice far less - the log only grows when an agent seals something, which today is a handful of records per day Log list: testing Contact: info@gblin.digital - https://gblin.digital What the log is, briefly: an append-only RFC 6962 log whose leaves are records of AI actions - an agent submits the SHA-256 of its input and output plus a public label, and receives a portable receipt (signature, inclusion proof, signed checkpoint). The tree root is additionally anchored once a day on a public chain. Design note, including what a receipt does NOT prove: https://github.com/gblinproject/gblin-treasury-risk-regime/blob/main/docs/ai... We implement the log side of c2sp.org/tlog-witness as of 21 August: on every size change we POST "old <n>", an RFC 6962 consistency proof and the signed note to each configured witness, retry from the size a witness reports in a 409, and store the returned cosignature bound to the exact (origin, size, root) it was issued for. A stored cosignature is served in /log/checkpoint only while it still matches the current size, never re-attached to a later tree. Who cosigns, and at which size, is public at /log/witnesses. Useful for your decision: the log is tiny - 18 leaves today, most of them our own tests - so the load is negligible and so, honestly, is the current utility to anyone but us. It is operator-signed only, which is exactly why we are asking. Anyone can check it without trusting us: /log/checkpoint, /log/consistency, /log/leaves (raw records, rebuild the tree yourself) and a zero-dependency offline verifier in the repository. If you would rather we come back when the log carries real third-party usage, that is a fair answer. We are separately asking to participate as a witness operator for testing/log-list.1.
