Storage
04.CESS
CESS (Cumulus Encrypted Storage System) is a blockchain powered decentralized storage and content delivery network (CDN) infrastructure for Web3. Users and creators alike use the platform for on-chain data sharing, whilst builders can develop and deploy DApps.
Offering the most optimal Web3 solution for storing and retrieving high-frequency dynamic data, CESS reshapes the value distribution and circulation of data assets whilst ensuring data sovereignty and user privacy. By utilizing a decentralized physical infrastructure network (DePIN) model, CESS drives mass deployment of network nodes globally through incentives.
CESS network consists of four layers: Blockchain Layer, Distributed Storage Resource Layer , Distributed Content Delivery Layer, and Application Layer. CESS’s R²S consensus mechanism coordinates the network resources and network load, guarantees data security and integrity through proprietary technologies with data ownership protection, technologies such as Proof of Data Reduplication and Recovery (PoDR²), Multi-format Data Rights Confirmation (MDRC), and decentralized proxy re-encryption. CESS aims to be the first decentralized storage network that supports large-scale commercial applications.
CESS is also compatible with EVM and WASM, and the underlying development framework Substrate is also friendly to cross-chain applications. Its technology stack can support most Web3 applications and the development needs of enterprise-level applications.
