This document proposes a new scheme to avoid address reuse while retaining some of the convenience of address reuse, keeping recoverability purely from Bitcoin time chain and avoiding visible fingerprint. The scheme has negligible average overhead.

Design for a CoinSwap Implementation for Massively Improving Bitcoin Privacy and Fungibility
25/5/2020
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.

| This document is an attempt to define metrics quantifying the degree of privacy provided by a bitcoin transaction. | |
| Objectives | |
| Definition of metrics measuring the resistance of a transaction to a set of attacks against users privacy. | |
| Attacks considered in the scope of these metrics are: | |
| - Merged Inputs Heuristic: methods identifying the inputs controlled by a same entity | |
| - Coinjoin Sudoku: methods identifying the links existing between the inputs and outputs of a transaction |
