A signed-server verification service that lets browsers and agents prove contact with a live public internet server.

Landing page captured for the 2026-09-14 issue.

Field notes

The service uses a challenge-response flow rather than treating successful page access as proof: a client sends unpredictable text, then verifies an Ed25519 signature and matching challenge in the returned payload. The response also carries server time and a SHA-256 hash of the versioned rule text. Public-key references include a well-known JSON endpoint, a DNS TXT record, and a repository copy, while MCP clients can call verify_real_internet.
