According to Foresight News, UniSat Wallet, a Bitcoin inscription wallet, has submitted a modular proposal at the Layer1 Foundation forum. The proposal outlines a modular mechanism for BRC-20, providing a new method to support various inscription-based applications within the existing BRC-20 framework. The modules operate independently, with each indexer only parsing data related to the modules they are interested in, while maintaining BRC-20 balance consistency with other indexers.

The proposal divides the modules into black and white modules. Black modules only support deposits and do not support withdrawals, while white modules support withdrawals.
