## Overview

Provenance provides two documented ways to issue and verify academic certificates: a standalone browser demo and a Solidity contract. In both, certificate details are hashed and verification checks for an issued record; the contract’s issuance is admin-restricted and its records are stored on-chain. The README describes the frontend as mirroring the contract, not as connected to it. Source excerpts were unavailable, so frontend internals and contract-to-blockchain mechanics are shown only at the documented level.

Main entry points: [`index.html`](https://github.com/06082006/academic-verification-dapp/blob/main/index.html) (Browser demo), [`AcademicVerification.sol`](https://github.com/06082006/academic-verification-dapp/blob/main/AcademicVerification.sol) (Issue certificate)
