What is Nervos Network (CKB)?

Deep Dive

1. Dual-Layer Architecture

Nervos employs a novel two-layer structure:
- Base Layer (Common Knowledge Base): A Proof-of-Work (PoW) blockchain focused on security and decentralized consensus. It stores "common knowledge"—immutable data like asset ownership and smart contract states. Users pay in CKBytes (CKB) to store data, aligning miner incentives with long-term network health.
- Computation Layer: Handles transaction processing and dApp execution off-chain, enabling scalability without compromising the base layer’s security. This separation allows developers to choose trade-offs between speed and decentralization (CoinMarketCap).

2. Cell Model & Flexibility

Unlike account-based systems (e.g., Ethereum), Nervos uses a cell model—UTXO-like data structures that combine storage and programmability. Each cell can hold assets, code, or state, enabling:
- Custom cryptographic schemes (e.g., quantum-resistant algorithms like SPHINCS+).
- Seamless upgrades without hard forks.
- Cross-chain interoperability through protocols like RGB++ and Fiber Network, which connect Bitcoin and Ethereum ecosystems (Daily Hodl).

3. Quantum Resistance

Nervos integrates post-quantum cryptography (PQC) to counter threats from quantum computing. Its modular design allows developers to implement algorithms like lattice-based CRYSTALS-Dilithium or hash-based SPHINCS+ via lock scripts. This flexibility ensures backward compatibility while preparing for future security challenges.

Conclusion

Nervos Network rethinks blockchain architecture by prioritizing security, adaptability, and cross-chain functionality. Its layered approach and quantum-ready infrastructure position it as a forward-looking platform for decentralized innovation. Can Nervos’ Bitcoin-native tools like RGB++ become the standard for scalable BTCFi (Bitcoin DeFi)?
