ZKP-LD Playground

Experimental: Do not use in production

• Playground for ZKP-LD: Zero-Knowledge Proof of Linked Data

• You can sign and verify JSON-LD-based Verifiable Credentials (VCs) using a experimental version of BBS+ signatures with Data Integrity

• You can derive and verify proofs from multiple VCs, supporting "user-friendly" selective disclosure and proof of termwise equality

• Built on jsonld-proofs, rdf-proofs-wasm, rdf-proofs, and docknetwork/crypto

• Supports "user-friendly" selective disclosure (TODO: elaborate further)

• Hosted at https://playground.zkp-ld.org

• For a detailed guide, visit our documentation.

Prerequisites for development

• Node.js
• npm

How to run a local server

Clone this repository and run the app:

$ git clone https://github.com/zkp-ld/zkp-ld-playground.git
$ cd zkp-ld-playground
$ npm install
$ npm run dev

Then, open http://localhost:5173 to view it in your browser.

Overview

ZKP-LD Playground is a web-based demonstration application for experimenting with Linked Data-based Verifiable Credentials (VCs) that support selective disclosure and zero-knowledge proofs. It allows you to issue VCs, selectively disclose attributes when presenting them, and verify the presented VCs with predicate proofs.

This application has many features below:

• Generate Verifiable Credentials (VCs)
• Present a Verifiable Presentation (VP) from multiple VCs
• Selective disclosure
• Secret Holder Binding for VC
• Predicate Proof
  • Range Proof for Integer
  • Range Proof for Datetime
