Introduction to FISCO BCOS
Born in mid-2016 within China's Financial Blockchain Shenzhen Consortium (FISCO), FISCO BCOS emerged from a research initiative aiming to develop a financial-grade consortium blockchain platform. Initially leveraging Ethereum's C++ codebase for its smart contract capabilities, the project underwent extensive customization to meet the stringent demands of enterprise financial applications.
Key principles driving FISCO BCOS development:
- Avoiding wheel reinvention by building upon proven technologies
- Community-driven growth through open-source collaboration (GPL v3.0 licensed)
- Financial sector specialization with enhanced security and governance features
Core Architectural Differences
1. Token Economics
FISCO BCOS: Completely removed native cryptocurrency mechanics
- No block rewards or token issuance
- Balance fields in accounts become irrelevant
- Financial assets implemented via custom smart contracts
- Rationale: Focuses on operational efficiency improvements rather than speculative token economics
2. Consensus Mechanisms
| Feature | FISCO BCOS | Ethereum |
|---|---|---|
| Algorithm | PBFT/Raft (pluggable) | Ethash (PoW) → PoS |
| Finality | Instant deterministic finality | Probabilistic finality |
| Performance | Seconds per block | Minutes per block |
| Energy Efficiency | Low computational overhead | High energy consumption |
| Node Roles | Approved validators | Open mining/validating |
