RGB proxy is a server done to facilitate the relay of load data between RGB wallets, having better UX for end user and also avoiding attacks of users, spammers, etc.
This feature can be used in the following workflow:
-Payee validates the content of consignment file;
-The payer pots consignment file with UTXO blinded provided by the payee in the invoice;
-The payee asks the proxy server if consignment file is associated to the UXTO blinded;
(continue here)
-If exist UTXO blinded to the Payee;
-The payee posts message ACK if is ok, but if fail can post a message NACK;
-The payee asks proxy sever about ACK/NACK. If successful will process Bitcoin transaction;
Conclusion
With enhancement of tools for RGB as RGB Proxy, I trust the layer 3 will be very important for next year/decade, due the world enter in a dystopia of high control like CBDC. Like this RGB will help people the exit of this Matrix.
Hal Finney had a vision about bitcoin-backed banks could "issue their own digital cash currency, redeemable for bitcoins."The idea was based George Selgin’s Free Banking research.
