P.S.
If services like ChipMixer operated based on blinded bearer certificates, then they'd be in many ways superior to both of the above mixing methods. Someone should work on this.
How exactly is it possible to obfuscate the connection between i/p & o/p for Mixer operator using
blinded bearer certificate? I mean, how can the final design of a transaction be done without the address that is going to have the spending right? And as soon as that address is included, connection between i/p & o/p gets revealed to the Mixer operator. No?
