According to Foresight News, the Bitcoin Layer 1 asset issuance protocol RGB++ has released its roadmap, with plans to launch by the end of March. The protocol will support the issuance and trading of non-fungible tokens (NFTs) and fungible tokens (FTs). Additionally, CKB is set to launch the CKB Layer 2 Lightning Network by the end of the year and integrate RGB++.
RGB++ is a Bitcoin Layer 1 asset issuance protocol proposed by CKB co-founder Cipher. It uses 'isomorphic binding' to map Bitcoin UTXOs to CKB Cells and leverages the script constraints on the CKB chain and Bitcoin chain to verify the correctness of state calculations and the validity of ownership changes. This allows Bitcoin Layer 1 assets to gain smart contract capabilities without the need for cross-chain bridges.
