Hello everyone !
Here is a link to Mobius, a “Trustless Tumbling for Transaction Privacy” on Ethereum, that we have developed as a Proof of Concept here at Clearmatics: https://github.com/clearmatics/mobius
As outlined in the Mobius wiki (see wiki section on github), and in the different issues that have been opened in the past months, Mobius is nothing else than a prototype. Being aware of its current flaws, we are trying to see if such a contract-based solution could be a good way to enhance privacy on Ethereum, without additional pre-compiled contracts or modifications in the EVM, while keeping decent performances and gas cost.
Any feedback is, of course, welcomed,
Cheers,
