According to Foresight News, Cipher Wang, co-founder of Nervos, launched the RGB++ Protocol. The protocol is an extension of the Bitcoin smart contract protocol RGB, which uses one-time seals and client verification technology to manage state changes and transaction verification. RGB++ maps Bitcoin UTXO to the Cell of Nervos CKB through isomorphic binding, and uses script constraints on the CKB chain and the Bitcoin chain to verify the correctness of state calculations and the validity of ownership changes. RGB++ solves the technical problems of the original RGB protocol in actual implementation and provides more possibilities, such as blockchain-enhanced client verification, transaction folding, shared state and ownerless contracts, non-interactive transfers, etc. It brings Turing-complete contract extensions and performance extensions to Bitcoin without cross-chain and without loss of security.
