Blockchain Technology Overview
Blockchain is a distributed ledger technology that chronologically links data blocks in a chain structure secured by cryptography. This ensures tamper-proof and forgery-resistant records, as defined by China's Ministry of Industry and Information Technology in their White Paper on Blockchain Technology Development.
This technology drives internet evolution from the information era to the value era, enabling secure and efficient value transfer comparable to information exchange. Langchao Blockchain Platform emphasizes practical integration with business scenarios over foundational technology alone, offering:
- Blockchain PaaS & SaaS services
Two-layer architecture:
- Infrastructure Layer: Blockchain networks + off-chain storage
- Platform Service Layer: Scenario-adapted APIs + user interfaces
Platform Architecture
Hybrid Blockchain Infrastructure
Langchao combines multiple technologies for diverse business needs:
Hyperledger Fabric
- Global leader in permissioned chains
- Features: Multi-channel support, private data encryption, "Execute-Order-Validate" consensus (~500-600 TPS)
- Used by Alibaba, Tencent, and Huawei for enterprise solutions
Ethereum (PoA Consensus)
- Enables token incentives (e.g., Wucaishi reward tokens in smart city apps)
- Authority Proof (PoA) ensures regulatory compliance
Audit Sidechain
- Java/MySQL-based high-TPS solution (~10,000+ TPS)
- Anchors data to Fabric mainchain for immutability
Blockchain Explorer (BCE)
- Unified interface for hybrid chain data
- Role-based data isolation and enhanced readability
Off-Chain Storage
- Supports SQL/NoSQL databases, Hadoop, and cloud services
- Key management via blockchain for encrypted big data

FAQ
Q: How does Fabric achieve high performance?
A: Its "Execute-Order-Validate" model parallelizes transaction processing unlike traditional sequential execution.
Q: Can enterprises customize token rules?
A: Yes, via smart contracts on Ethereum (PoA) or upcoming Fabric FabToken support.
Q: What's the advantage of audit sidechains?
A: They enable high-frequency logging (e.g., API call tracking) without congesting mainchains.
