Blockchain Implementation in Golang

A blockchain implementation in Go, demonstrating essential concepts of blockchain technology. This project includes basic block structures, proof-of-work consensus, cryptographic transaction signing, and block verification.

Features

• Block Structure: Each block holds data, a hash, a previous hash link, a nonce, and transactions.
• Proof of Work (PoW): Implements a proof-of-work system using md5 hashing to maintain blockchain integrity.
• Wallets and Transactions: Supports RSA key pairs for wallets, transaction creation, signing, and verification.
• Genesis Block: Automatically creates the genesis (first) block with a Coinbase transaction.
• CLI Demo: Demonstrates the creation of blocks, transactions, and verification on the blockchain.
