Atomic Multi-Path Payments Over Lightning

Olauluwa Osuntokun posted to the lighting network developer’s mailing list a proposal for extending the complexity and utility of payment paths. The scheme is called “Atomic Multi-path Payments” (AMP) and Osuntokun claims “the beauty of the scheme is that is requires no fundamental changes to the [current] protocol”. The purpose of the scheme is to provide a way for a sender to break payments up into “chunks”. There is unusued space in data trasmitted between lighting nodes as a byproduct of tor compliance. This unusued space has been isolated as a 65 bytes that can be used as processing instructions for nodes along the payment path.

When considering payments that are broken into chunks, it is an excellent idea both technically and economically. Relay and processing becomes subdivided further than presently among nodes. More nodes increases security by reducing probability of select certain paths redundantly. Economically, single payments dispursed over a wider set of nodes provides a more fair (probabilisitically speaking) distrobution of work.

Crypto Open Exchange Protocol

Nicolas Dorier proposed a new BIP via the bitcoin-dev mailing list which he referred to as the Crypto Open Exchange COX Protocol. From the summary of the BIP:

The goal of this BIP is to specify a simple protocol which makes possible decoupling of payment processors from exchanges.
