Wasabi creates trustless CoinJoin transactions over the Tor anonymity network. The CoinJoin coordinator cannot steal from, nor breach the privacy of the participants.
CAN I HURT MY PRIVACY USING WASABI?
No. The worst thing that can happen (through user’s negligence post-mix) is that the level of your privacy stays the same as before coinjoin. It is crucial to understand that Wasabi is not a fool-proof solution if you neglect to practice coin control after the mixing process.
DO I NEED TO TRUST WASABI WITH MY COINS?
No, Wasabi's coinjoin implementation is trustless by design. The participants do not need to trust each other or any third party. Both the sending address (the coinjoin input) and the receiving address (the coinjoin output) are controlled by your own private keys. Wasabi merely coordinates the process of combining the inputs of the participants into one single transaction, but the wallet can neither steal your coins, nor figure out which outputs belong to which inputs.
WHAT IS A “COINJOIN”?
A mechanism by which multiple participants combine their coins (or UTXOs, to be more precise) into one large transaction with multiple inputs and multiple outputs. An observer cannot determine which output belongs to which input, and neither can the participants themselves. This makes it difficult for outside parties to trace where a particular coin originated from and where it was sent to (as opposed to regular bitcoin transactions, where there is usually one sender and one receiver).
