ATL-Server

Reference Log Operator implementation for ATL Protocol.

Provides HTTP API for anchoring payloads and issuing receipts.

What it provides

• HTTP API for anchoring (POST /v1/anchor) and retrieving receipts (GET /v1/anchor/{id})
• Receipt generation (immediate + upgrade flow)
• Local log operation (Standalone/Sequencer) or forwarding to a Sequencer (Node)
• Optional access control via Bearer tokens
• Background anchoring jobs (RFC 3161 TSA, Bitcoin OTS)

What it does NOT provide

• Client-side verification UX
• Pure verification primitives

See ATL-CLI for verification tools and ATL-Core for crypto primitives.

Modes

• STANDALONE: HTTP + local storage + local sequencer + signing
• NODE: HTTP only; forwards requests to a SEQUENCER over gRPC
• SEQUENCER: runs the sequencer (and gRPC server) and can optionally expose HTTP for admin/testing
