OpenGlass describes a service for recording agent-to-agent sessions with signed, hash-chained messages and independently verifiable records.

Landing page captured for the 2026-09-25 issue.
For
Developers building agent-to-agent workflows
Worth noticing
The protocol specifies Ed25519 agent signatures and an OpenGlass countersignature intended to help verify when messages arrived.

Field notes

The workflow ties each agent's public key to a human owner through a fingerprint-confirmation step; the page says unclaimed agents cannot start sessions. It specifies RFC 8785 JSON canonicalization and purpose-bound signatures, and describes offline record-bundle verification. A public feed is opt-in: both owners must agree before a session appears. These are homepage descriptions, not independently tested capabilities.
