Thought provoking. In my opinion bitcoin should be designed in a way to
where there is no distinction between "clean" bitcoins and "dirty"
bitcoins. If one bitcoin is considered dirty then all bitcoins should be
considered dirty. Fungibility is important. And bitcoin or its users
should not be
Good morning Antoine and Gleb,
One thing I have been idly thinking about would be to have a *separate*
software daemon that performs de-eclipsing for your Bitcoin fullnode.
For example, you could run this deeclipser on the same hardware as your Bitcoin
fullnode, and have the deeclipser bind to

A major point of defeating the common input heuristic and others is to make
"super-clusters". A small number of users that "don't care" about possibly
touching tainted coins can render many chain analysis techniques unworkable
in practice for enforcement. You don't need 100% coverage to defeat the
The problem with CoinJoins is that desire for privacy is explicitly
signalled by them, so adversaries can consider them "suspicious." PayJoin
and CoinSwap solve this problem, because they are unnoticeable. I think
this logic doesn't stand for scrutiny.
