Cipher, founder of CELL Studio, discussed challenges with the RGB protocol and introduced RGB++ at Bitcoin Singapore 2024.

RGB++ aims to enhance Bitcoin transactions with isomorphic binding technology and Turing-complete capabilities.

Challenges with the RGB protocol include interactive operations, data availability, interoperability, and issues with smart contract/script execution environments.

RGB++ links Bitcoin transactions with the CKB blockchain, enabling Turing-complete contracts while maintaining Bitcoin Layer 1 security.

The protocol allows asset 'leaping' between different UTXO-based chains like Bitcoin, Litecoin, Liquid, and CKB.

RGB++ introduces state channels and the AppChain stack as solutions for increasing transaction throughput.

The RGB++ protocol is live on the Bitcoin mainnet, with an SDK released on April 3rd, aiming for easier integration for developers.
