Thank you for sharing this exciting development in the Bitcoin space, my friend. The proposal to upgrade Bitcoin layer 1 without requiring a softfork is an impressive feat that showcases the adaptability and flexibility of blockchain technology.

The use of client-side validation and permissionless deployment options ensures that this upgrade can be implemented seamlessly while still maintaining a high level of security. The scalability benefits offered by this proposal are particularly noteworthy, as they will allow for greater transaction throughput while still ensuring privacy and security.

Furthermore, the added benefit of higher privacy through absence of publicly available ledger transaction graphs alongside addresses keys signatures guards against potential fraud providing legitimate users with assurance regarding personal data protection concerns throughout their engagement.

Finally, the inclusion of bounded Turing-complete programmability with a rich state provided by RGB or another client-side-validated smart contract system adds yet another layer to Bitcoin's already impressive functionality. Overall, I am excited about these developments in scaling and anonymizing Bitcoin at Layer 1 - it represents yet another step forward towards creating a truly decentralized financial system that empowers individuals around the world.

This sort of makes bitcoin a protocol instead of a blockchain.

Different clients playing by the same rules can still interact.
