purify::puresign::TopicProofCache Struct Reference

Cacheable topic-bound nonce-proof template. More...

#include <legacy.hpp>

Static Public Member Functions

static Result< TopicProofCache > build (std::span< const unsigned char > topic)
 Builds a reusable verifier template for one exact topic.

Data Fields

Bytes topic
Bytes eval_input
NativeBulletproofCircuitTemplate circuit_template
Bytes template_digest
ExperimentalBulletproofBackendCache backend_cache

Detailed Description

This bundles the exact topic together with the public-key-agnostic circuit template needed for topic-bound proof(R) creation and verification. Reuse the same instance across multiple users for the same topic.
