[SOLUTION] Please describe your proposed solution

This proposal is part of a family of proposals that collectively aim to create Buriza, a comprehensive Cardano wallet software suite spanning mobile, browser, and desktop applications. Buriza, named after the Japanese word for Blizzard, will be designed to be the best open-source, fully decentralized, and cross-platform Cardano wallet. It will empower users with maximum control over their entire wallet infrastructure. By combining open-source transparency, backend flexibility, and utilizing a standardized protocol for interacting with UTxO-based blockchains through the UTxO RPC standard, Buriza will enable users to self-host, choose their backend servers, self-verify and install the software itself and fully customize the wallet’s security, privacy, and functionality to meet their specific needs. While other proposals focus on platform-specific apps, this one focuses on the core library, which is the backbone that powers all of them. 

In order to power Buriza and its features, Buriza.Core will serve as the foundational library driving multiple applications across platforms (Desktop, Browser, Mobile). As the core library powering Buriza, Buriza.Core will offer developers essential wallet functionalities, including transaction building, signing, and submission, as well as security protocols and cross-platform compatibility. Additionally, it will expose real-time blockchain state information, enabling developers to retrieve data such as user balances, assets, and other relevant blockchain details. It will ensure that components like Buriza.Desktop, Buriza.Browser, and Buriza.Mobile will rely on it for fundamental functionality. 

Problem Statement 

There are various Cardano wallets available today, and while they are functional and serve their purpose, they still come with the following significant limitations: 

• Centralized Dependency: Many wallets depend on third-party services or centralized backend servers to access blockchain state, introducing potential security risks and undermining long-term reliability, particularly if these servers go offline or are shut down. 

 

• Closed-Source: The rise of closed-source wallets means users can no longer inspect the code, raising concerns about security vulnerabilities and lack of accountability. 

 

• Limited User Control: Many wallets limit users' control over wallet infrastructure, making it challenging to interact with UTxO-based blockchains in a decentralized manner. This not only undermines user autonomy and privacy but also restricts the user’s ability to customize the wallet according to their individual preferences. 

 

• Poor User Experience: Existing wallets often face issues such as unclear transaction dialogs, confusing account balance displays, and challenges in rendering digital assets like NFTs or media (e.g., audio and books). Additionally, transaction history is often poorly organized, making it difficult for both crypto-native and average users to understand their activities. Furthermore, many wallets are limited to specific platforms—available on mobile but not desktop—resulting in inconsistent user experiences across devices. 

 

• Insufficient Decentralization: Although some wallets allow users to edit the submission node, this is not enough to ensure true decentralization, as many still rely on third-party infrastructure for essential functions like balance and transaction history retrieval. 

 

• Failure to Comply with Standards: Several wallets fail to comply with Cardano Improvement Proposal (CIP) standards, limiting interoperability, security, and compatibility within the ecosystem. 

To highlight these differences, a comparison table between existing Cardano wallets and Buriza will be provided to illustrate how Buriza will overcome these limitations.

Key Features 

Despite the limitations of current Cardano wallets, Buriza.Core aims to overcome these challenges by implementing the following features: 

• Open-Source & Decentralized: Buriza.Core will be fully open-source, encouraging community participation, auditing, and continuous improvement. Its decentralized architecture will ensure that users maintain full control without relying on centralized entities or services. Additionally, Buriza.Core will adhere to Cardano Improvement Proposals (CIPs), ensuring compliance with established standards within the ecosystem for enhanced compatibility and security. 

 

• Self-Install & Self-Host: Buriza.Core will empower users to deploy their wallet backends on their own infrastructure, providing complete control over data, security, and privacy. In contrast to existing wallets that primarily provide a "submit node" configuration—where users connect to a node exclusively for transaction submissions— Buriza.Core will ensure that all wallet data is directly fetched from the blockchain node. Although some wallets provide a way to edit the submission node, this is not enough to ensure complete decentralization and control, as they still rely on third-party infrastructure for critical operations. With Buriza.Core, reliance on third-party providers or intermediaries for key information, such as account balances or transaction history, will be eliminated, making it ideal for privacy-conscious users seeking true decentralization. Fully integrated with the user’s own blockchain node, Buriza.Core will guarantee data authenticity and security, delivering a more robust, independent experience. 

 

• Backend Flexibility: Buriza.Core will enable users to choose their preferred backend host, granting flexibility in selecting trusted nodes. This feature enhances decentralization and minimizes dependency on any single provider or centralized infrastructure, ensuring a more resilient and customizable experience for users. 

 

• Full Node and Light Wallet Support: Buriza.Core’s architecture will support both full node and light wallets, ensuring that users have flexibility depending on their preferences and technical requirements. Full-node wallet users can now access dApps via the UTxO RPC protocol, a feature currently unavailable in the only full-node wallet for Cardano users, Daedalus. This gives users greater flexibility and functionality, allowing them to interact with decentralized applications while maintaining full control of their own data. 

[IMPACT] Please define the positive impact your project will have on the wider Cardano community

Positive Impact on the Cardano Community: 

• Enhanced User Security: Buriza.Core will give users full control over their wallets, from the code itself to the entire infrastructure, eliminating the risks associated with centralized wallets. In centralized systems, users are often forced to trust third-party providers with sensitive information, such as seed phrases, which exposes them to potential security breaches, hacks, or mismanagement. Buriza.Core will ensure that users never have to rely on centralized entities for key wallet data or security, maintaining full ownership and control over their seed phrases and wallet infrastructure whilst preventing such vulnerabilities. This will lead to safer, more secure interactions within the Cardano ecosystem, aligning with the core principles of decentralization and user autonomy. 

 

• True Decentralization: By enabling self-hosting and allowing users to choose their backend servers, Buriza.Core promotes decentralization, aligning with Cardano’s core mission. This reduces dependency on any single provider and strengthens the resilience of the network. For example, stake pools could provide access to their copy of the blockchain using UTxO RPC, offering enhanced flexibility. Additionally, they have the ability to cater exclusively to their delegators, giving pool operators more control over who can access their infrastructure. This approach not only decentralizes data access but also encourages the growth of a more diverse and resilient ecosystem. 

 

• Community-Driven Innovation: Buriza.Core will be open-source, encouraging community participation and continuous improvement. Its collaborative nature will enable both developers and users to contribute to its ongoing development, ensuring the wallet evolves to meet the needs of the broader Cardano ecosystem. 

 

• Boost to DeFi and DApp Growth: By offering a secure and decentralized wallet with top user experience, Buriza.Core will encourage more users to confidently engage in Cardano’s DeFi and DApp ecosystems. This will drive the growth and adoption of decentralized applications, further advancing Cardano’s potential. For instance, full-node wallet users will be able to participate in dApps without concerns about the risks tied to closed-source or centralized wallets, ensuring a more secure and transparent experience in DeFi environments. 

 

• Network Stability and Health: Buriza.Core will contribute to the decentralization and robustness of the network by distributing wallet infrastructure across multiple backends, thereby enhancing the overall stability and health of the Cardano blockchain.
