Core Components

1. Blockchain Core

• Block Structure: Implements blocks with transactions, validator signatures, and state roots
• Chain Management: Handles block creation, validation, and chain reorganization
• State Management: Uses Merkle Patricia Tries for efficient state storage
• Transaction Pool: Manages pending transactions

2. Consensus Mechanism

• Proof of Stake: Energy-efficient consensus with validator selection
• Validator Management: Handles validator registration, staking, and rewards
• Slashing: Implements penalties for malicious behavior
• Staking: Manages token staking and unstaking operations

3. Networking

• P2P Protocol: Implements custom protocol for node communication
• Node Discovery: Uses Kademlia DHT for peer discovery
• Message Broadcasting: Efficient message propagation
• Connection Management: Handles peer connections and disconnections

4. Cross-Chain Bridge

• Bridge Operations: Manages cross-chain asset transfers
• Bridge Validators: Special validators for bridge operations
• Asset Locking: Handles asset locking and unlocking
• Transaction Verification: Cross-chain transaction validation

5. Wallet

• Key Management: Secure storage of private keys
• Transaction Creation: Creates and signs transactions
• Balance Management: Tracks account balances
• CLI Interface: Command-line interface for wallet operations

6. Explorer

• Backend API: RESTful API for blockchain data
• Frontend UI: React-based user interface
• Real-time Updates: WebSocket for live data
• Search Functionality: Search blocks, transactions, addresses

7. API & SDK
