I. RGB++ Protocol and CKB's No-Bridge Cross-Chain: Building a Bridge for Bitcoin Finance
The RGB++ protocol is a key technology designed by Nervos CKB for Bitcoin Layer 2 expansion. The core of RGB++ is to utilize CKB's unique architecture and homomorphic binding technology to map Bitcoin's UTXO model to CKB's Cell model, achieving no-bridge cross-chain and smart contract support for Bitcoin assets. This design not only breaks the security and trust issues of traditional cross-chain bridges but also provides liquidity and multi-asset management capabilities for Bitcoin assets in the CKB network.
