Design for a CoinSwap Implementation for Massively Improving Bitcoin Privacy and Fungibility

25/5/2020

Abstract

Imagine a future where a user Alice has bitcoins and wants to send them with maximal privacy, so she creates a special kind of transaction. For anyone looking at the blockchain her transaction appears completely normal with her coins seemingly going from address A to address B. But in reality her coins end up in address Z which is entirely unconnected to either A or B.

Now imagine another user, Carol, who isn't too bothered by privacy and sends her bitcoin using a regular wallet which exists today. But because Carol's transaction looks exactly the same as Alice's, anybody analyzing the blockchain must now deal with the possibility that Carol's transaction actually sent her coins to a totally unconnected address. So Carol's privacy is improved even though she didn't change her behaviour, and perhaps had never even heard of this software.

	here's what's in the .htm file you can pull from the SEC's site (the one that breaks the SEC's app).
	FWIW I also tried replacing the final emptyline/end with `/end because that is more standard.
	after that i also tried replacing all the spaces with backticks because that is also more standard.

	i have also verified that all the characters are within the limited set used for uuencoding.
	see https://en.wikipedia.org/wiki/Uuencoding for more on uuencoding.

	my current best guess is there's something wrong with the padding for the final few bytes but i could
	easily be wrong...
