Struct Verifier 

pub struct Verifier { /* private fields */ }

Groth16 proof verifier

Create once with a verification key, then verify multiple proofs.

Example

use signedby_sdk::{Verifier, VerificationKey};

let vk = VerificationKey::from_json(vk_json)?;
let verifier = Verifier::new(vk);

let result = verifier.verify(&proof, &public_inputs)?;
assert!(result.valid);

Implementations

impl Verifier

pub fn new(vk: VerificationKey) -> Self

Create a new verifier with the given verification key

pub fn verify( &self, proof: &Groth16Proof, public_inputs: &PublicInputs, ) -> Result<VerificationResult, SdkError>

Verify a Groth16 proof

Returns a VerificationResult with:

• valid: whether the proof is cryptographically valid
• npub: the user’s pseudonymous identifier (NOSTR public key)
• merkle_root: the group membership tree they proved membership in
• session_binding: prevents proof replay across sessions

pub fn verify_json( &self, proof_json: &str, public_inputs_json: &str, ) -> Result<VerificationResult, SdkError>

Verify proof from JSON strings (convenience method)
