Seal announces mainnet launch, Walrus becomes the first decentralized data platform with access control

ChainCatcher reported that the decentralized key management solution Seal has announced its mainnet launch, providing encryption and access control features for any developer building on this protocol.

With the release of Seal, Walrus has become the first decentralized data platform to natively support on-chain access control, enabling the integration of programmable data access solutions in applications of any scale. This unlocks more use cases, including sharing proprietary training data or fine-tuning models under strict access policies, token-gated subscription services, and dynamic game content. Currently, dozens of projects based on Walrus are using Seal, including Inflectiv, Vendetta, TensorBlock, and others, demonstrating the immediate practical value of on-chain encryption and access control. In addition, OneFootball plans to use Walrus + Seal to provide content with built-in copyright management, and Watrfall is leveraging Walrus + Seal to unlock new models of distribution, ownership, and fan engagement. Alkimi is already processing over 25 million ad impressions daily on Walrus, ensuring the confidentiality of client data through Seal. Reportedly, Seal was launched by Mysten Labs, the original contributors to the Sui blockchain, aiming to achieve programmable, application-specific access control logic through Move, and utilizing identity- and threshold-based cryptographic technologies to ensure seamless and secure client-side encryption/decryption processes.
