Zero-knowledge proof

What it means: the issued code, pulse, and timestamp are bound to this proof. If any field is changed, verification fails.

Technical: fields are committed with Poseidon, then validated with a Groth16 proof for fast public verification.

Circuit: Groth16
Proof system used for verification.
: 4021A7252E00F0BC
Proof identifier for this claim. Verifies quickly and deterministically.
: 13284b8e2e59523a8c6845aff06160c9f1d367ce27230b8232dc1efccc4966d5
Hash commitment that binds the committed fields into the proof.

Practical rule: if it looks the same but isn’t the same, it won’t verify.
