Recomputes the SHA-256 over the payload body and checks the Ed25519 signature against RC Quantum's public key. Edit any number, or hit Tamper, and the signature breaks.

Checking…
How it works. The verifier canonicalizes the body (sorted keys, compact), hashes it with SHA-256, and verifies the Ed25519 signature with the published public key — the same check any consuming agent runs. Nothing is sent anywhere; it all happens in your browser. Live-parallel shadow data from an isolated clone of the RC Quantum production system, real exchange fills. Data, not investment advice.
