Wasabi Wallet
Open-source, non-custodial, privacy focused Bitcoin wallet for Windows
Wasabi is an open-source, non-custodial, privacy-focused Bitcoin wallet for desktop, that implements trustless coinjoin. Wasabi creates trustless coinjoin transactions over the Tor anonymity network. The coinjoin coordinator cannot steal from, nor breach the privacy of the participants. Coinjoin is 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). Coinjoin can be applied multiple times, and as many transactions are grouped together, participants may save on transaction fees. Coinjoin is the preferred method of gaining privacy in the Bitcoin network.
