feat: Decentralized Key Generation (DKG) as a Service on Avail

[akuon]

Summary: Integrate a Decentralized Key Generation (DKG) service into the Avail network, allowing users to securely generate and manage cryptographic keys in a distributed and trustless manner.

Detailed Description:

Avail's secure enclave technology provides a foundation for building trustless applications. However, securely generating and managing cryptographic keys remains a significant challenge. This feature request proposes incorporating a DKG service within Avail, enabling users to:

• Generate shared keys: Multiple parties can collaboratively generate cryptographic keys without any single entity possessing complete control.
• Threshold signatures: Implement threshold signature schemes where a certain number of parties need to contribute to sign a transaction, enhancing security and fault tolerance.
• Key management: Securely store and manage keys generated through DKG within Avail enclaves, ensuring confidentiality and integrity.

Use Cases:

• Multi-party computation (MPC): Securely conduct computations on private data without revealing the underlying information, requiring distributed key generation for participant authentication and data integrity.
• DAO governance: Implement secure and transparent voting mechanisms within DAOs, leveraging DKG for key generation and threshold signatures to authorize actions without centralized control.
• Custody wallets: Enhance the security of custody wallets by employing DKG to generate and manage keys across multiple servers or enclaves, mitigating single points of failure and insider threats.

Alternative Solutions:

• Hardware Security Modules (HSMs): While offering strong security, HSMs introduce centralized points of control and potential vulnerabilities.
• Shamir's Secret Sharing: This manual key splitting technique lacks the automation and trustless environment offered by DKG.

Additional Context:

• Integration with existing Avail services: Seamlessly integrate the DKG service with other Avail offerings like secure computation and confidential storage for a comprehensive suite of privacy-preserving functionalities.
• Standardization and interoperability: Adhere to established DKG standards (e.g., BLS) to ensure compatibility with other blockchain ecosystems and applications.
• Security considerations: Conduct thorough security audits and implement best practices for key management within Avail enclaves to guarantee the integrity and confidentiality of generated keys.

Benefits:

• Enhanced security: Mitigates the risks associated with centralized key generation and storage, fostering trust and transparency in decentralized applications.
• Improved user experience: Simplifies key management for users by providing a secure and user-friendly interface within the Avail ecosystem.
• Unlocks new use cases: Enables the development of novel applications requiring secure and distributed key management, expanding the potential of Avail technology.

Challenges:

• Technical complexity: Implementing a robust and efficient DKG service while maintaining security and scalability requires careful design and engineering.
• User adoption: Educating users on the benefits and proper usage of DKG is crucial for widespread adoption within the Avail ecosystem.
• Regulatory considerations: Depending on the specific implementation, regulatory compliance regarding key management and cryptographic protocols might need to be addressed.

By incorporating a DKG service, Avail can empower users with secure and trustless key management capabilities, fostering the development of innovative and privacy-preserving decentralized applications while addressing the inherent challenges associated with centralized key generation and storage. This feature aligns with Avail's vision of building a secure and scalable foundation for future decentralized applications.
