Blockchain Implementations in Go

This repository provides implementations and simulations of two critical aspects of blockchain technology: Ethereum mining using Proof of Work (PoW) and Zero-Knowledge Proofs using the gnark library. Each implementation is written in Go and serves as an educational resource to understand the underlying mechanisms of these technologies.

Ethereum Mining Simulation in Go

This section simulates the Ethereum mining process using a simplified Proof of Work mechanism. It's an educational implementation, aiding in the understanding of how Ethereum mining, block validation, and consensus are achieved in a PoW blockchain.

Key Features

• Block Mining: Simulates the process of mining a block by finding a nonce that satisfies specific conditions.
• Multi-Threading: Utilizes multiple threads (goroutines) to enhance the mining process.
• Block Validation: Includes a validation process to verify if the mined block meets the required conditions.

Zero-Knowledge Proofs with gnark

This part of the repository demonstrates the implementation of zero-knowledge proofs using the gnark library. It’s an example of how a prover can prove the knowledge of secret information without revealing the information itself.

Key Features

• Cubic Circuit Definition: A simple cubic equation circuit is defined to simulate the zero-knowledge proof.
• Proof Generation: Generates a zk-SNARK proof that the prover knows the values satisfying the circuit without revealing them.
• Proof Verification: Verifies the generated proof, validating that the prover knows the secret values.
