Go-Blockchain

Go-Blockchain is an advanced blockchain platform built using Go. It is designed to provide a robust, secure, and extensible framework for developing blockchain-based applications. The platform includes comprehensive features such as smart contracts, decentralised identity management (DID), multi-signature transactions, and a gamification system to incentivise user participation.

Key Features

1. Blockchain Core

• Efficient Data Structure: Utilizes a Merkle tree for transaction validation and efficient data storage.
• Consensus Mechanisms: Supports multiple consensus algorithms, including Proof of Work (PoW) and Proof of Stake (PoS).
• Dynamic Difficulty Adjustment: Automatically adjusts mining difficulty based on network conditions.
• Optimized Block Size: Configurable maximum block size for scalability and performance.

2. Smart Contracts

• Custom DSL: Write and deploy smart contracts using a domain-specific language (DSL).
• Contract Execution Engine: Executes contracts within a virtual machine, supporting functions like SET, ADD, and CALL.
• Persistent State Management: Smart contracts can maintain state across transactions.

3. Decentralized Identity (DID)

• DID Registry: Register and manage digital identities on the blockchain.
• Authentication: Authenticate users using cryptographic signatures.
• Attribute Management: Store and manage identity attributes securely on the blockchain.

4. Multi-Signature Transactions

• Enhanced Security: Require multiple signatures for transaction approval, increasing security.
• Flexible Configuration: Specify the number of required signatures and expiration times for transactions.
• UTXO Integration: Validate multi-signature transactions against the UTXO (Unspent Transaction Output) set.

5. Gamification

• User Engagement: Reward users with points for participating in the network (e.g., mining, voting, and transactions).
• Cooldown Mechanism: Prevent abuse by enforcing cooldown periods between actions.
• Pattern Detection: Detect and respond to suspicious patterns of activity.

6. Secure Networking

• TLS Encryption: Ensure secure communication between nodes using TLS (Transport Layer Security).
• Peer Discovery: Automatically discover and connect to other nodes in the network.

Getting Started

Prerequisites

• Go: Make sure you have at least Go 1.23.0 installed. You can download it here.

Installation

1. Clone the Repository:

   git clone https://github.com/Dyst0rti0n/go-blockchain.git
   cd go-blockchain
   

2. Build the Project:

   go build -o go-blockchain
   

3. Or Run:

   go run .
   

Running a Node

1. Start a Node:

   ./go-blockchain -node localhost:8080
   

2. Connect to Peers:

   ./go-blockchain -node localhost:8080 -peers "localhost:8081,localhost:8082"
   

Using the Blockchain

1. Create a Transaction:

   Enter choice: 1
   Enter sender: alice
   Enter recipient: bob
   Enter amount: 50
   Enter fee: 1
   

2. Mine a Block:

   Enter choice: 2
   

3. Deploy a Smart Contract:

   Enter choice: 4
   Enter smart contract code: SET key value
   

4. Execute a Smart Contract:

   Enter choice: 5
   Enter smart contract ID: <contract-id>
   Enter method name: CALL
   

5. Print the Blockchain:

   Enter choice: 3
