Nervos
Nervos CKB is a modular, Bitcoin-isomorphic Layer 1 blockchain focused on security, decentralization, flexibility, and interoperability.
Overview
Nervos CKB (Common Knowledge Base) is a Layer 1 blockchain designed to provide a secure, decentralized, and flexible foundation for decentralized applications and Layer 2 scaling solutions. It is built on a Proof-of-Work consensus mechanism and uses a UTXO (Unspent Transaction Output) model similar to Bitcoin, making it Bitcoin-isomorphic. This design allows Nervos CKB to enhance Bitcoin's capabilities by adding programmability and scalability without relying on cross-chain bridges. The blockchain supports all cryptographic primitives, enabling seamless interoperability with heterogeneous blockchains, sidechains, state channels, and Layer 2 networks.
Nervos CKB's modular architecture separates security and scalability concerns. The base layer offers robust security and decentralization, while Layer 2 networks built on top provide high throughput and scalability, potentially reaching millions of transactions per second. Protocol-level account abstraction is supported by default, improving user experience for decentralized applications. Developers can build custom EVM-compatible sidechains using tools like Axon, or leverage the low-level virtual machine to create complex smart contracts without limitations.
The platform offers extensive developer resources, including SDKs in Rust, Go, Java, and TypeScript, CLI tools, debugging utilities, and comprehensive documentation. Nervos CKB also features a novel tokenomics model that aligns incentives across miners and network participants, ensuring long-term security and sustainability. The ecosystem includes wallets, mining tools, and a community fund DAO to support ongoing development. Developers can quickly start building by installing the OffCKB CLI and accessing tutorials for common tasks like token creation, data storage, and smart contract scripting.
The Problem
Many blockchains struggle to balance security, decentralization, and scalability simultaneously. Existing Bitcoin infrastructure lacks programmability and interoperability, limiting its use for modern decentralized applications. Additionally, cross-chain bridges introduce security risks and complexity.
