Nervos CKB is a proof-of-work Layer 1 blockchain that uses the RGB++ protocol to enable Bitcoin smart contracts without bridges or wrapped tokens by binding Bitcoin UTXOs directly to its Cell Model. Founded in 2018 by former Ethereum developers, it has grown to over 400 dApps and 800,000 JoyID wallet users, though recent price volatility and security breaches have challenged adoption despite continued engineering development.
Nervos CKB is a proof-of-work Layer 1 blockchain designed to add smart contract functionality to Bitcoin through its RGB++ protocol, which cryptographically binds Bitcoin UTXOs to CKB Cells without requiring bridges or consensus changes. Founded in 2018 by former Ethereum developers, the project has grown its ecosystem to over 400 dApps and 800,000 JoyID wallet users, though recent security incidents including a $3.9 million bridge hack in June 2025 have challenged adoption momentum despite continued engineering development.
