By default, all transactions made on Ethereum are public. Tornado Cash is a decentralized privacy preserving solution built on Ethereum which adds privacy through obfuscation. Users can place Ether and some stable coins in prescribed increments [1 Eth, 10 Eth, 100 Eth...] into the Tornado Pool. In return, they are issued a private note, with which they can withdraw funds at a later time to a different address.

We were joined by Roman Semenov, co-founder of Tornado Cash, to talk about how the protocol works, how it was set up, community governance, and where he sees Tornado Cash's position in the quickly growing privacy ecosystem on Ethereum.

Topics covered in this episode:

Roman's background and how he got into crypto
The problem Tornado Cash solves and how the protocol works
What tokens are supported and can you swap tokens?
Smart contracts and zero knowledge
Costs involved for deposits and withdrawls
Weaknesses of the protocol

The regulatory threat to private coins in the future
Tornado Cash's roadmap and how they see themselves positioned in the wider ecosystem
