Seal is the decentralized secrets management solution. The solution allows developers to encrypt and regulate access to sensitive data without needing to rely on a central server. 

By being present at SUI Testnet, Seal can now be tested by the developer community. This is to build a prototype and provide input for further improvements.

Different from Web2 solutions like AWS KMS or Google Cloud KMS, Seal comes as a reliable platform for Web3 scale. The system supports a variety of protocols, and is suitable for scenarios where security and privacy are top priorities.

Seal Architecture

Seal combines multiple layers of technology to ensure scalability and data protection, including:

On-chain access control: Access rules are defined via smart contract Move on the SUI network, so it is transparent and auditable.

Threshold encryption: The decryption key is split into several parts that are stored on different servers. To unlock data, only part of the key is needed.

Client-side encryption: The encryption and decryption process is done on the user's side, so the server never sees the original data.

Storage agnosticism: Seal can be used with various decentralized storage systems such as Walrus.

With this combination of technologies, Seal allows developers to control who can access data, when, and under what conditions.

Seal Use Cases

Seal's flexible capabilities mean it can be adopted in various scenarios, including:

NFT-based premium content: Similar to Web3's version of Patreon or Substack, only NFT holders or verified subscribers can access exclusive content.

End-to-end chat encryption: A conversation application that guarantees user privacy with local encryption.

Web3 gaming: Mission data or items can only be unlocked after players complete certain challenges.

NFT transfer with time-lock: Suitable for closed auctions or secure DAO voting systems.

Personal and health documents: Data is stored on Walrus and is only accessible to users at Seal's discretion.

One example of a real implementation is a demo marketplace application that utilizes Seal, SUI, and Walrus. This application enables subscription-based and whitelist content systems to run completely on-chain—secure, efficient, and transparent.

Seal's Future Plans

Mysten Labs encourages the community to try Seal on SUI Testnet and provide feedback. This feedback will become the basis for the development of further features, such as:

Multi-Party Computation (MPC): Delivers a decentralized collective decryption process.

Server-side decryption: On-server decryption option for applications that require a lightweight front-end.

Digital Rights Management (DRM): Decrypt only on trusted devices, similar to the DRM systems used by Netflix or YouTube.

All of these features aim to create a higher standard of Web3 security, with privacy preservation, decentralized access, and integrated encryption.
