Nervos CKB: The next generation Layer 2 that empowers Bitcoin, opening a new era of BTCFi
In the field of blockchain, Bitcoin's position as the first-generation public chain is unshakable, but its native network is limited in scalability and programmability. Nervos CKB (Common Knowledge Base) overcomes these limitations by designing it as a Layer 2 extension of Bitcoin, combining the PoW (Proof of Work) and UTXO (Unspent Transaction Output) models, which not only maintains the decentralization and security of Bitcoin, but also brings cross-chain interoperability and smart contract support. This article will analyze in detail the architecture of Nervos CKB, the RGB++ protocol innovation, and its application in the BTCFi (Bitcoin Decentralized Finance) ecosystem.
