The open-source privacy wallet on the Cardano blockchain offers users a simple and easy-to-use solution for managing their transactions and personal information in a private and secure manner. Unlike mixer services, which have been stigmatized as tools for criminal activity, a privacy wallet offers a much more positive perspective on privacy. This is because a wallet is a personal and decentralized tool that allows individuals to take control of their own privacy, rather than relying on a third-party service to protect their information. Additionally, the wallet's cross-chain compatibility, compliance with privacy regulations, and resistance to side-channel attacks ensures that users' personal information is protected, even when making transactions on the blockchain. This not only protects users' privacy, but also helps to mitigate the stigma surrounding private transactions on the blockchain.
Furthermore, many jurisdictions, such as GDPR, HIPAA, and the Privacy Act of 1974, require that private information be protected. This makes it necessary for organizations and individuals to implement measures to protect personal information, and a privacy wallet is an effective tool for doing so. The wallet's compliance with these regulations ensures that users' personal information is protected in accordance with the law, and the wallet's resistance to side-channel attacks ensures that this information remains private and secure, even when making transactions on the blockchain.
The scope of this project includes the development of an open-source privacy wallet on the Cardano blockchain that is private by default, compliant with relevant privacy regulations, and resistant to side-channel attacks. The wallet will utilize the W3 DID standard for storing user identity information, and will also incorporate Atala Prism and the Midnight sidechain for enhanced privacy and security.
DID: Decentralized Identifier, a type of identifier that is globally unique and decentralized, as specified in the W3 DID standard. GDPR: General Data Protection Regulation, a European Union regulation that establishes strict standards for the protection of personal data. HIPAA: Health Insurance Portability and Accountability Act, a US law that establishes national standards for the protection of personal health information. W3: World Wide Web Consortium, an international community that develops open standards for the web.

The wallet will be accessible through a user-friendly interface, and will not require any specialized knowledge or technical expertise to use.
The open-source privacy wallet will be available for download and installation on a variety of devices, including desktop computers, laptops, and mobile devices. The wallet will be compatible with the following operating systems:
- Windows
- macOS
- Linux
- iOS
- Android
The design and implementation of the open-source privacy wallet will be subject to the following constraints:
The wallet must be built on the Cardano and/or Midnight blockchain(s). The wallet must utilize the W3 DID standard for storing user identity information. The wallet must be compliant with GDPR, HIPAA, and the Privacy Act of 1974, as well as any other relevant privacy regulations. The wallet must be resistant to side-channel attacks.
The open-source privacy wallet will provide a user-friendly interface that allows users to easily manage their transactions and personal information. The interface will include the following features:
- A simple and intuitive design that is easy to navigate and use.
- A clear and concise display of all relevant information, including the user's balance, transaction history, and personal information.
- The ability to easily manage and make transactions, including the ability to send and receive funds and view transaction details.
- The ability to securely store and manage user identity information in accordance with the W3 DID standard.
The open-source privacy wallet will be available for download and installation on a variety of devices, including desktop computers, laptops, and mobile devices. The wallet will be compatible with the following hardware:
- Desktop computers and laptops with at least 2GB of RAM and 100MB of free storage space.
- Mobile devices with at least 1GB of RAM and 50MB of free storage space.
The open-source privacy wallet will be built on the Cardano and/or Midnight blockchain, and will utilize the following software components:
- The W3 DID standard for storing and managing user identity information.
- Atala Prism and the Midnight sidechain for enhanced privacy and security.
