💡 Want to upgrade to ciissversion:3?

All 14 of your relays validate cleanly on CIISS v2 (RSA fingerprint proofs). The new CIISS v3 spec replaces per-relay RSA proofs with a single shared ed25519 family-id proof — same url, one published file for the whole family.

To migrate, change torrc ContactInfo to:

ciissversion:3 url:arbitrary.ch proof:uri-familyid-ed25519

And on a secure host, generate the happy-family key:

tor --keygen-family /path/to/myfamily # then deploy myfamily.secret_family_key to every relay's KeyDir

Publish .public_family_id at /.well-known/tor-relay/ed25519-family-id.txt. Allow ~24h after restarting Tor for Onionoo to refresh family_ids. Full guide: aroivalidator setup guide.
