MMB blockchain network

🧱 MMB Blockchain Network

MMB Blockchain is a custom-built experimental blockchain system designed from scratch with a modular, multi-layered architecture. It features a basic Proof of Authority (PoA) consensus, built-in smart contract handling, and support for decentralized applications (dApps) via a web interface.

🔧 System Architecture

The system is organized into three primary layers:

🧩 Layer 0 – Core Blockchain (Consensus & Networking)

• Full blockchain engine: blocks, mempool, hashing
• PoA Consensus: only authorized leaders are allowed to sign blocks
• Peer-to-peer node communication and block propagation
• Each node has its own private/public keypair (RSA or ECDSA)
• Signature validation and block rejection logic

📜 Layer 1 – Smart Contract & Token Layer

• Transaction types supported:
  • mintburn (native MMB token)
  • native, transfer
  • stake, deploy_contract, call_contract (under development)
• Smart contract data handled via transactionData field
• Cryptographic abstraction layer: pluggable sign/verify adapters (RSA, ECDSA)

🌐 Layer 2 – dApps & Web3 Interface

• User-facing frontend interfaces (in progress)
• Features: Wallets, Token Dashboard, Custom DEX
• Support for Web3 or custom RPC API

---

✅ Completed Features

• PoA-based block creation and signature validation
• Node synchronization and propagation of valid blocks
• Cryptographic adapter system (RSA, ECDSA)
• Minting restricted to authorized keys
• Hex-encoded block outputs for readability

---

🚧 Roadmap

• Lightweight VM engine for smart contracts
• Stake-based validator rotation
• REST/Web3 APIs and explorer UI
• Cross-chain bridge & asset-backed token logic (e.g., USDT, BTC)
• NFT & DAO modules
