Staging and production C2SP witnessing request for Enigm Key Transparency

[ntncstr]

Hello TrustFabric Team,

Enigm is implementing an independent C2SP-compatible Key Transparency Log for public encryption-key verification.

We would like to request:

1. temporary staging witnessing for our preproduction log;
2. information about TrustFabric's planned production witness;
3. availability and pricing for SLA-backed production witnessing.

Preproduction identity:

Origin: keys.enigm.dev/v1
Checkpoint URL: https://keys.enigm.dev/v1
C2SP vkey: keys.enigm.dev/v1+06c61fb2+AcBPl120wgVJe9QWPfa8Pazv3kG99wFcZvr316Msrab6
Maximum checkpoint rate: one checkpoint every two minutes
Expected lifetime: long-running
Contact: security@enigm.io

The public checkpoint endpoint is currently being finalized at its permanent URL.

The future production origin will be:

keys.enigm.io/v1

The production signing key has deliberately not been generated or published yet.

Enigm plans to use a 2-of-3 quorum of independently operated witnesses. No private keys, user data or account identifiers will be submitted to witnesses.

For production, could you please provide information about:

• production witness availability and expected timeline;
• SLA and monitoring;
• persistent witness state and rollback protection;
• incident and key-rotation notification;
• supported C2SP versions;
• Ed25519 and ML-DSA-44 support;
• geographic and administrative independence;
• pricing and contractual requirements.

Kind regards,

Enigm Security Team
