Project Introduction
Cumulus Encrypted Storage System (CESS) is a high-speed, secure, and scalable decentralized cloud storage network developed with Substrate. It aims to become the first decentralized storage project that offers full data services for large scale commercial applications. The entire network consists of three main modules: blockchain layer, data storage and content distribution layer, and application layer. CESS’s novel Random Rotational Selection (R²S) Consensus Mechanism coordinates the network resources and network load and guarantees data security through mechanisms such as Proof of Data Reduplication and Recovery (PoDR²). In addition, the Multi-format Data Rights Confirmation (MDRC) mechanism and decentralized proxy re-encryption to ensure data integrity, security, traceability and privacy.
