Live Hardware Verification · M2M
Hardware attests.
The chain verifies.
This is not a simulation. Connect to a real Lindblad node on your local network, request a cryptographic signature derived from its silicon PUF, verify the ECDSA math, and confirm on-chain that the hardware is authorized for M2M commerce. The proof lives in physics, not in promises.

Live Verification · Four Cryptographic Steps
1
Request fresh challenge
GET /api/challenge — node generates unique nonce from PUF + Chua HSC + timestamp
2
Hardware signs with PUF key
POST /api/sign — node derives ECDSA key from silicon and signs (challenge + nodeId + ts + Chua nonce)
3
Verify signature mathematically
Recover signer address from signature using elliptic curve math — must match derived address
4
Verify on-chain registration
Query M2MEscrow contract on Arbitrum Sepolia — is this hardware address authorized for M2M commerce?
Hardware Verified
The signature was produced by physical silicon. The math checks out. The chain confirms authorization. This is M2M commerce with cryptographic ground truth — not trust, not assumption, not custody.
"Real silicon. Real signatures.
Real on-chain verification."
