Welcome to BlockGoChain, a hands-on project designed to help developers build a functional blockchain system from scratch using Go. This project explores key blockchain concepts such as blocks, hash functions, proof-of-work algorithms, and transaction management.

The goal of this project is to implement the fundamental components of a blockchain, starting with block structures and gradually building out features like mining, transaction handling, and wallet functionality. By completing this project, you will gain a deep understanding of how blockchain systems operate, from hashing blocks to managing digital assets.

1. Blocks and Blockchain Structure
   • Create the fundamental structures of a blockchain, including blocks and chains of blocks.
   • Understand and compute hashes for secure block validation.
   • Create the first "Genesis" block and continue adding blocks to the chain.
2. Proof of Work Algorithm
   • Implement a proof-of-work algorithm for mining new blocks.
   • Verify and validate the mining process using computational power.
   • Mine new blocks and test the algorithm.
3. Transaction Management
   • Define a transaction structure to handle asset transfers.
   • Integrate transactions within blocks for safe and secure operations.
4. Wallet Functionality
   • Build wallet features to manage digital assets.
   • Add signing and verification functionality to ensure secure transactions.
   • Implement wallet functionality and test its reliability.

• Task 10: Create Transaction Structures
• Task 11: Add Transactions to Blocks
• Task 12: Test Transaction Handling

• Task 13: Build Wallet Functionality
• Task 14: Sign and Verify Transactions
• Task 15: Test Wallet Features

• block.go - Contains the structure and logic for individual blocks in the blockchain.
• blockchain.go - Manages the blockchain structure, adding blocks, and validating them.
• proof.go - Implements the proof of work system, including mining functionality.
• wallet.go - Handles wallet-related functionality, including signing and verifying transactions.
• main.go - The main entry point of the application, bringing all components together.
