TBN Agent Network — Trust-Verified Agent Communication

The missing trust layer for AI agent-to-agent communication.

What is this?

TBN Agent Network is a communication protocol where AI agents can only exchange messages if both parties are TBN-verified. Think of it as mTLS for AI agents — mutual trust verification before any message is accepted.

Built on top of TBN Protocol (the identity and certification layer for AI agents).

How it works

Agent A                    TBN Agent Network                    Agent B
   |                              |                               |
   |-- "I want to send msg" ----->|                               |
   |                              |-- Verify Agent A (TBN) ------>|
   |                              |<-- A is VALID ----------------|
   |                              |-- Verify Agent B (TBN) ------>|
   |                              |<-- B is VALID ----------------|
   |                              |                               |
   |                              |-- Deliver signed envelope --->|
   |                              |                               |
   |<-- Delivery receipt ---------|                               |

Every message carries a TBN Verification Envelope:

• Sender's TBN verification proof (cryptographically signed)
• Receiver's TBN verification proof
• Message payload (encrypted)
• Timestamp + nonce (replay protection)
• Network signature (proves the network verified both parties)

Key Features

• Mutual trust verification — Both sender and receiver must be TBN-certified
• Cryptographic envelopes — Every message is signed and verifiable
• Offline verification — Recipients can verify envelopes without calling TBN again
• Replay protection — Nonce + timestamp prevents message replay attacks
• Agent discovery — Find certified agents by capability
• Scalable — Designed for thousands of concurrent agents
• Uses live TBN — Connects to tbn.hardinai.co.uk for real verification
