Nervos Network operates its own blockchain, known as the Nervos Common Knowledge Base (CKB), which is designed to be a layer 1 blockchain with a unique architecture. Here’s a breakdown of its key features:

1. Nervos CKB (Common Knowledge Base)

• Native Blockchain: Nervos CKB is an independent blockchain, not built on top of another (like Ethereum or Bitcoin).
• Layer 1 Focus: It serves as the foundational layer for the Nervos ecosystem, providing security, decentralization, and a base for higher-layer solutions.
• UTXO Model: Unlike Ethereum’s account-based model, CKB uses a UTXO (Unspent Transaction Output) model, similar to Bitcoin, but with improvements for smart contracts.
• Cell Model: CKB introduces a cell-based data structure, allowing for more flexible and efficient smart contract execution.

2. Layer 2 Solutions (Built on CKB)

While CKB is the base layer, Nervos also supports layer 2 solutions for scalability and interoperability:

• Godwoken: A layer 2 solution that enables EVM (Ethereum Virtual Machine) compatibility, allowing Ethereum dApps to run on Nervos.
• Polyjuice: A layer 2 framework that brings Ethereum-like smart contract functionality to CKB.

3. Interoperability with Other Blockchains

• Force Bridge: A cross-chain bridge that connects Nervos CKB with Ethereum, allowing asset transfers between the two networks.
• CKB-VM: A virtual machine that supports multiple programming languages (Rust, C, etc.) and can interact with other blockchains.

Conclusion

Nervos Network has its own blockchain (CKB) as the core layer, with additional layer 2 solutions (like Godwoken and Polyjuice) to enhance functionality and interoperability. It is not built on top of another blockchain but rather designed as a standalone, scalable, and interoperable base layer.

Yes, Nervos Network is programmable and supports smart contracts and decentralized applications (DApps). Here’s how it works:

1. Smart Contracts on Nervos

Nervos uses CKB-VM (Common Knowledge Base Virtual Machine), a Turing-complete execution environment that allows developers to write and deploy smart contracts. The primary smart contract language is Rust, with support for other languages like C and AssemblyScript via WASM (WebAssembly).

2. Layer 2 Solutions for Scalability

Nervos is designed as a Layer 1 blockchain (CKB) with Layer 2 solutions (like Godwoken and Polyjuice) to enhance scalability and smart contract functionality:

• Godwoken: A Layer 2 rollup that enables EVM-compatible smart contracts, allowing developers to port Ethereum DApps to Nervos.
• Polyjuice: A Layer 2 solution that brings Ethereum Virtual Machine (EVM) compatibility to Nervos, allowing Solidity-based smart contracts to run on CKB.

3. Decentralized Applications (DApps)

Nervos supports DApps through:

• EVM Compatibility (via Godwoken & Polyjuice)
• Native CKB Smart Contracts (written in Rust/WASM)
• Cross-Chain Interoperability (via Nervos DAO and Layer 2 solutions)

4. Key Features for Developers

• Deterministic Execution: CKB-VM ensures predictable smart contract behavior.
• Low-Cost Transactions: Nervos uses UTXO-based accounting (like Bitcoin) but with smart contract capabilities.
• Interoperability: Nervos can interact with other blockchains via bridges and Layer 2 solutions.

Conclusion

Nervos is fully programmable, supports smart contracts, and enables DApps through its Layer 2 solutions. Developers can choose between native CKB smart contracts (Rust/WASM) or EVM-compatible contracts (Solidity) via Godwoken and Polyjuice.

The Nervos Network (CKB) is designed to be a high-performance, scalable blockchain with a focus on security and decentralization. Here’s an overview of its transaction speed, confirmation time, and throughput:

1. Transaction Speed & Confirmation Time

• Typical Block Time: ~10 seconds (adjustable via governance).
• Finality: Transactions are considered final after ~10 blocks (approximately 1–2 minutes), ensuring security against double-spending.
• Fast Confirmations: Some wallets and services may allow "fast" confirmations after 1–2 blocks (~10–20 seconds), though full security is achieved after finality.

2. Throughput (Transactions Per Second - TPS)

• Theoretical Max TPS: ~1,000+ TPS (depending on block size and network conditions).
• Real-World TPS: Typically 100–300 TPS under normal conditions, with the ability to scale higher during peak demand.
• Comparison: Nervos CKB is faster than Bitcoin (~7 TPS) and Ethereum (~15–30 TPS pre-L2 scaling), but slower than some Layer 1 chains like Solana (~2,000–65,000 TPS).

3. Factors Affecting Performance

• Dynamic Block Size: Nervos CKB uses a dynamic block size mechanism, allowing blocks to grow with demand (up to a limit).
• Layer 2 Scaling: Nervos supports Godwoken (EVM-compatible L2) and other rollup solutions, which can significantly boost throughput.
• Consensus Mechanism: Uses Proof of Work (PoW) for security, which is slower than PoS but more decentralized.

4. Comparison with Other Blockchains

Blockchain	Avg. TPS	Block Time	Finality Time
Nervos CKB	100–300	~10 sec	~1–2 min
Bitcoin	~7	~10 min	~1 hour
Ethereum (L1)	~15–30	~12 sec	~12–15 min
Solana	~2,000+	~400 ms	~1–2 sec

Conclusion

Nervos CKB offers fast (~10-second) block times and high throughput (100–300+ TPS), making it suitable for decentralized applications (dApps) and DeFi. For even higher performance, users can leverage Layer 2 solutions like Godwoken.

The Nervos Network (CKB) is designed as a layer 1 blockchain that supports on-chain data storage, but with some important limitations and considerations:

1. On-Chain Data Storage Capacity

• CKB (Common Knowledge Base) uses a UTXO (Unspent Transaction Output) model similar to Bitcoin, but with a key difference: cells (a type of UTXO) can store arbitrary data.
• Each cell can hold up to 1024 bytes of data by default, but this can be extended by locking more capacity (each byte costs 1 CKB).
• The total storage capacity of the Nervos Network is theoretically unlimited (as long as users are willing to pay for storage), but practical limits depend on:
  • Network consensus rules (currently, no hard cap, but storage costs are enforced).
  • Economic incentives (users must pay for storage, so spam is discouraged).

2. How Data Storage Works on Nervos

• Data is stored in cells (similar to how Bitcoin stores UTXOs).
• Each cell has a capacity (measured in bytes), and storing data consumes that capacity.
• Storage costs are paid in CKB (1 CKB = 1 byte of storage).
• Data can be updated or deleted by spending the cell and creating a new one.

3. Comparison to Other Blockchains

Feature	Nervos (CKB)	Ethereum	Bitcoin
On-Chain Storage	Yes (cells)	Yes (contract storage)	Limited (OP_RETURN)
Storage Cost	Paid in CKB (1:1)	Paid in gas (ETH)	Limited (OP_RETURN)
Scalability	High (layer 1)	Limited (gas costs)	Very limited
Data Size Limit	Up to 1024 bytes per cell (extendable)	Depends on gas	80 bytes (OP_RETURN)

4. Use Cases for On-Chain Storage on Nervos

• Decentralized identity (DID)
• NFT metadata
• Smart contract data
• Lightweight dApps that need persistent storage

5. Limitations & Considerations

• Cost: Storing large amounts of data can be expensive (1 CKB = 1 byte).
• Performance: Large-scale storage may require off-chain solutions (e.g., Nervina, a decentralized storage network built on CKB).
• No native file storage: Unlike IPFS or Arweave, CKB is not optimized for large files (better for small, structured data).

6. Alternatives for Large-Scale Storage

If you need large-scale decentralized storage, consider:

• Nervina (a CKB-based storage network)
• IPFS + CKB (for off-chain storage with on-chain references)
• Arweave (for permanent, low-cost storage)

Conclusion

Nervos does support on-chain data storage, but it’s best suited for small to medium-sized structured data. For large files, off-chain solutions like Nervina or IPFS are more practical.
