ZK-Puzzle-Chain: A Simple Chain, Integrating RISC-Zero's zkVM for PoW

ZK-Puzzle-Chain is an experimental blockchain project that combines the concepts of Proof-of-Work (PoW) and Zero-Knowledge Proofs (ZKP) to create a novel consensus mechanism.

This project is built on top of the RISC-Zero's zkVM.

This project is an experimental exploration of integrating RISC-Zero's zkVM into a blockchain system. It's designed for personal learning.

Features

  • Proof-of-Work consensus mechanism
  • Zero-Knowledge Proofs for block verification
  • JSON-RPC API for interacting with the blockchain
  • Storage layer using PostgreSQL
  • Just for demo, no transaction, no account, no smart contract, no P2P

About ZK-POW

zk-pow is a simple proof-of-work algorithm that is used to secure the blockchain. It is implemented in Rust and uses the RISC Zero zkVM to create and verify proofs of correct computation.

Feel free to play with it and try to break it.

Getting Started

Prerequisites

Installation

  1. Clone the repository:

    git clone https://github.com/keroro520/zk-puzzle-chain.git
cd zk-puzzle-chain

  2. Build the project:

    cargo build --release

Running the Node

cargo run --bin client --release

Interacting with the Blockchain

You can interact with the blockchain using the JSON-RPC API. The node will start a JSON-RPC server on http://localhost:3030.

Running the Miner

cargo run --bin miner --release
