Seal has launched its mainnet, introducing a decentralized key management solution that offers encryption and access control for developers. This launch allows Walrus to become the first decentralized data platform to support on-chain access control, facilitating programmable data access for various applications. Use cases include proprietary data sharing, token-gated services, and dynamic game content. Projects like Inflectiv, Vendetta, and TensorBlock are already leveraging Seal through Walrus, highlighting its practical benefits. Additionally, OneFootball and Watrfall are exploring new content management and distribution models using this technology.
