Sukhavati is a decentralized cloud service network focused on storage. Based on TEE and Substrate, it implements a low-consumption and meaningful storage verification mechanism: EPoSt (Efficient Proof of Spacetime). On the basis of this architecture, Sukhavati will establish a decentralized data access gateway covering both Web3.0 and Web2.0 storage ecosystems to provide unified data storage, retrieval, and management services for Web3.0 applications.
