Introduce the new narrative of #CKB . What is RGB++?

A new protocol designed based on RGB concepts (single sealing, client verification).

Main changes:

1. Change the virtual machine to RISC-V and use Rust to write contracts, which is more developer-friendly than the original AluVM.

2. In addition to client verification, another UTXO chain (CKB in this case) is also used for additional verification, double guarantee.

3. Use another UTXO chain as the DA layer to avoid the loss of the entire RGB asset due to historical data loss in some extreme cases.

Single sealing allows assets to use BTC consensus to resist double spending, and client-side verification ensures that the assets are valid. #
