kienhaminh Blockchain Engineering Standards
This skill provides expert guidelines for building the decentralized layer with a focus on security, scalability, and economic robustness.
Core Responsibilities
- Protocol Architecture: Design tokenomics, governance structures, and ensuring incentive alignment across the network.
- Smart Contract Mastery: End-to-end lifecycle management of smart contracts on EVM (Solidity/Yul) and SVM (Rust/Anchor).
- Advanced Security: Protect value through formal verification, fuzzing, and rigorous audit preparation.
- Scaling Solutions: Architect solutions using L2s, Optimistic/ZK Rollups, and AppChains.
Technical Standards & Best Practices
Development Lifecycle
- Environment: Master usage of Hardhat and Foundry (Forge/Cast/Anvil) for EVM; Anchor for Solana.
- Testing: Beyond unit tests—implement invariant testing, fuzzing (Echo/Medusa), and fork testing.
- CI/CD: Automated pipelines for linting, testing, and deterministic deployments.
Optimization & Quality
- Gas Golfing: Optimize for gas efficiency using Yul/Assembly, storage layout packing, and calldata mastery.
- Code Quality: Enforce NatSpec documentation, strict linting (Solhint/Clippy), and clean code patterns.
Deployment & Ops
- Patterns: Use deterministic deployment (Create2) and manage upgrades via standard proxies (Transparent, UUPS, Diamond/EIP-2535).
- Security: Manage keys via Multi-sig (Gnosis Safe) and Timelocks. Automate ops with scripting.
Architecture Patterns
- Upgradeability: Future-proof contracts using Transparent, UUPS, or Diamond patterns.
- Interoperability: Connect chains using Bridges, Atomic Swaps, and CCIP.
- Data Integration: Index data with Subgraphs (The Graph) and secure external feeds via Oracles (Chainlink, Pyth).
Dynamic Stack Loading
- EVM (Ethereum/Polygon/Arbitrum):
- EVM Overview
- Solidity Development
- Deployment & Ops
- Mechanisms & Internals
- Solana: (Create
references/solana.mdif needed) - ZK & Privacy: Focus on ZK-SNARKs/STARKs for privacy and scaling.
