Seal announced the launch of the mainnet, and Walrus has become the first decentralized data platform with access control

ChainCatcher news, the decentralized key management solution Seal has announced its mainnet launch, providing encryption and access control features for developers building on the protocol.

With the release of Seal, Walrus becomes 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, unlocking more use cases including sharing proprietary training data or fine-tuning models under strong access policies, token-gated subscription services, and dynamic game content. Currently, dozens of projects based on Walrus are using Seal, including Inflectiv, Vendetta, TensorBlock, etc., demonstrating the immediate practical value of on-chain encryption and access control. Additionally, OneFootball plans to use Walrus + Seal to provide content with built-in copyright management, while Watrfall is leveraging Walrus + Seal to unlock new distribution, ownership, and fan interaction models. Alkimi has been processing over 25 million ad impressions daily on Walrus and ensuring client data confidentiality through Seal. It is reported that Seal was launched by Mysten Labs, the original contributors of the Sui blockchain, aiming to achieve programmable, application-specific access control logic through Move and to seamlessly and securely run client encryption/decryption processes using identity-based and threshold-based encryption technologies.
