Wasabi Wallet White Paper Wasabi provides users with unprecedented access to diverse privacy-enhancing features through an easy-to-use UI. From Wasabi's main screen, users can perform common crypto wallet actions, such as selecting a wallet, sending and receiving coins, and viewing the transaction history. In addition, users can easily choose to activate any combination of privacy-enhancing features, such as participation in a Coinjoin transaction (explanation follows). Coinjoin mixing protocol The most significant features in positioning Wasabi as a leading provider among privacy seekers are its embedded coin mixing mechanism and management of fungible coins. Wasabi is based on the WabiSabi fungibility network (formerly Zerolink, a framework to holistically design a privacy and fungibility setup for Bitcoin), which implements the Chaumian blinded Coinjoin mixing protocol, ensuring that no one, including Wasabi operators, can trace the coins before and after the mix. This mechanism enables several peers to join their coins in a single transaction and collaboratively build a transaction where each user provides some coins as inputs and fresh addresses as outputs. This mechanism’s goal is, of course, to enhance privacy and break the attribution link between inputs and outputs. Wasabi also offers Schnorr Blind Signature to assure that no one, including Wasabi operators and coordinators, will be able to link inputs and outputs. The CoinJoin mechanism implementation with the Wasabi non-custodial wallet also eliminates the risk of funds disappearing or being stolen. The wallet achieves this protection because each signature is created locally on the user’s computer, allowing the user to control the signature and preventing anyone from connecting a signature to alter a transaction or redirect funds. CoinJoin is a trustless mechanism by design, meaning the participants do not need to trust each other or any third party. All the addresses, both those addresses sending funds (“CoinJoin inputs”) and those receiving funds (“CoinJoin outputs”), are controlled by users’ private keys.
