The Payment Protocol described in BIP70 is really useful for making Bitcoin transactions (in store and online) more like other payments that consumers are used to and comfortable with today. Unfortunately, there has not been an easy way for desktop/mobile wallets (that are not always online) to securely utilize the Payment Protocol, and provide these benefits to users.

This new BIP, authored by Matt David (Netki), Justin Newton (Netki), Aaron Voisine (breadwallet), and James MacWhyte (breadwallet) is an extension to BIP70 that improves the Payment Protocol’s secure compatibility with desktop/mobile wallets, enhances transactional privacy, and makes Bitcoin transactions more human-friendly.

The 3 enhancements are as follows:

1) Allow for 2 way identity exchange
2) Identity exchange is encrypted to prevent man in the middle attacks
3) Allows mobile wallets to safely use the Payment Protocol by encrypting data sent to Store & Forward servers, and otherwise extending the protocol to support those servers

Here's a post that summarizes the BIP in more detail, and provides some example use cases that highlight the value prop: https://medium.com/@handlerjeff7/a-bitc ... .l0xasqc2y

This proposal was the result of a lot of collaboration, and we look forward to engaging with anyone/everyone that is interested. Needless to say, any feedback here is much appreciated.
