1. Executive Summary This project proposes the development of a modular blockchain built using the Substrate framework (Parity Technologies). The aim is to create a permissioned or permissionless network (to be defined) that supports decentralized finance (DeFi), digital identity, and enterprise system integration through APIs. The solution prioritizes security, forkless upgrades, on-chain governance, and scalable performance. 2. Objectives Build a functional blockchain based on Substrate with a custom runtime (Wasm + Rust). Implement essential pallets: accounts, native tokens, governance, staking (if PoS), and an asset marketplace. Provide integration tools: RPCs, SDKs (TypeScript, Rust), and a web UI (React/Tailwind). Establish CI/CD processes, automated testing, and complete technical documentation. Plan the roadmap for mainnet, public testnet, and security audits. 3. Project Scope In-Scope Runtime design and implementation (custom pallets + standard FRAME pallets). Node client based on Substrate and configuration of validators/nodes. Web wallet and admin/governance dashboard. Developer tools: JS SDK, dApp examples, and deployment scripts. Public testnet, documentation, and external security audits. Out of Scope Fiat asset custody. Centralized exchange infrastructure (can integrate via APIs if needed). 4. Core Technologies Runtime: Rust + FRAME (Substrate pallets) Client / Node: Substrate node template (Rust) Smart Contracts (optional): Ink! (for Wasm contracts) Frontend: React + TypeScript + polkadot.js / @polkadot/api CI/CD: GitHub Actions / GitLab CI Infra: Docker, Kubernetes for production, Prometheus + Grafana monitoring Security & Testing: Rust unit tests, integration tests with substrate-test-runtime, fuzzing, and external audits 5. Proposed Architecture Consensus Layer: BABE/GRANDPA (default in Substrate) for scalability and fast finality. Runtime: Wasm runtime with FRAME pallets compiled to WebAssembly for forkless upgrades. Core Pallets: System, Balances, Timestamp, Sudo (temporary), Session, Staking (if PoS), Democracy, Council, Treasury, Custom Pallets. Custom Pallets: Identity: Decentralized identity and claim management. Market: Asset/NFT listing and trading. Permissions: Access control for permissioned environments. Bridge (optional): Mechanisms to connect with other chains. APIs & SDKs: JSON-RPC via node, JS SDK using @polkadot/api, Rust client for backend integration. Frontend: dApp for users + governance dashboard. 6. Tokenomics (Suggested Model) Token Name: (to be defined) Utility: transaction fees, staking (network security), governance participation, service payments. Initial Supply: distributed among foundation, team, community, and incentive reserves. Mechanisms: partial fee burn (optional), staking rewards, treasury spending for ecosystem growth. 7. On-Chain Governance Implement Democracy + Council + Technical Committee pallets. Governance flows: proposals, referenda, fast-track motions, emergency pause via Technical Committee. Define thresholds: quorum, voting periods, council veto mechanisms. 8. Security Secure Rust coding practices and peer-reviewed code. Testing: unit tests, integration tests, property-based tests. External audits before mainnet (1–2 reputable security firms). Bug bounty program after public testnet release. 9. Development Plan (Roadmap) Phase 0 — Preparation (0–2 weeks) Requirements definition, architecture, and team formation. Decide between permissioned vs. permissionless. Phase 1 — Proof of Concept (4–8 weeks) Fork Substrate Node Template. Implement minimal runtime with Balances + simple custom pallet. Basic frontend for transfers. Phase 2 — Private Testnet (8–16 weeks) Implement governance, identity, and staking pallets. Add deploy scripts and observability tooling. Load testing and security testing. Phase 3 — Public Testnet & Audit (4–8 weeks) Launch public testnet, run bug bounty program, complete external audits. Phase 4 — Mainnet Launch Community-validated deployment and validator onboarding. Public communication and support. 10. Team (Suggested) Product Owner (PO) Blockchain Architect (Rust/Substrate) 2–4 Rust Developers (runtime & node) 1–2 Frontend Developers (React/TypeScript) DevOps Engineer (K8s, monitoring) QA / Test Engineer Security Specialist / Auditor UX Designer 11. Cost Estimate (High-Level) Initial 6-month development: team of 6–8 people. Infrastructure: Kubernetes, monitoring stack. External audits: US$20k–100k each. Additional costs: marketing, documentation, operations. 12. Risks & Mitigation Risk: Critical runtime bugs — Mitigation: audits, tests, emergency pause. Risk: Low adoption — Mitigation: incentive programs, enterprise partnerships. Risk: Regulatory issues — Mitigation: legal counsel per jurisdiction; permissioned network options. 13. Deliverables Runtime and node code in Git repository. Technical documentation and onboarding guides. SDKs and dApp examples. Public testnet with basic block explorer. Audit report and incident response plan. 14. Next Steps Conduct kickoff meeting to confirm requirements and governance model. Assemble team and initialize repos with CI. Build a PoC within 4–8 weeks for stakeholder demonstration.
