Each event carries a signature header so your endpoint can verify it really came from PaychainX.
This mirrors the real gateway sale response: AVS and CVV results, a risk decision with score, transparent fees, and the pq_proof. All values here are simulated for the demo.
Every settled payment posts a cryptographic receipt to this page. The proof_hash is computed in your browser as SHA-256(receipt || prev_hash). Each receipt is mathematically chained to the one before it, so a single altered field breaks every hash after it.
