Decentralized Storage
with Infinite Possibilities
The first decentralized cloud storage network to bridge the gap between Web3 and Web2 for large-scale commercial enterprise applications.
Store Your Data
Cumulus Encrypted Storage System (CESS)
A decentralized cloud storage network for online data storage and real-time sharing;providing a full-stack solution for Web3 high-frequency dynamic data storage. Users and creators may freely share and trade data and assets within the CESS network, regaining absolute ownership and control of their data. Our key technologies and innovations guarantee a prosperous, diverse, secure, and private data economics ecosystem.
Technical Advantages
CESS’s fair consensus mechanism (R²S) prevents node monopoly and ends the “miners’ dilemma.” The participation threshold for each node is fair and transparent. Altogether, it guarantees the efficiency of network consensus and block generation.
Scalable network with 10,000 TP and expandable storage space to meet the ever-increasing storage demand.
All uploaded data is duplicated, encrypted, and sharded before being stored in different nodes across the globe, achieving high degrees of data security and 99.99% data availability even if the system is under malicious attack or physically damaged in a natural disaster.
CESS’s millisecond data retrieval speed is achieved by well-designed network architecture and the assignment of two new miner types: cache and retrieval. First, rewards for retrieval miners on-chain were increased to further improve bandwidth quality; then the network was designed to store the requested data in the cache library in advance through the cache nodes. It can efficiently handle hot and cold data, ultimately achieving millisecond-level indexing, discovery, and return data to requesting applications quickly and securely.
DeOSS is a decentralized object-based mass storage service on the CESS network. It is a tool for storing and retrieving unstructured data and its metadata using HTTP API. DeOSS provides low-cost, secure, and scalable distributed storage service for high-frequency data storage needs. DeOSS protects data availability and integrity to empower users to control their data ownership. Both individuals and businesses can leverage DeOSS to securely store, administer and safeguard data.
Through pooling technology and a fair incentive mechanism, CESS achieves scalable and unlimited storage; using the innovative R²S consensus to implement intelligent management and scheduling services, CESS realizes how intelligent space management avoids wasting storage resources and maximizes storage space utilization.
MDRC extracts the digital fingerprints from data and stores them on-chain to prevent tampering. The uploaded digital fingerprints serve as proof of data ownership, enabling the tracing and visualizing of the data blood relationship on the CESS blockchain explorer.
Individuals or enterprises deploy applications through the built-in APIs, DeOSS, and SDK. Custom APIs for businesses are also available. The CESS network is cross-ecosystem, cross-platform, cross-chain friendly, supports WASM and EVM, and is compatible with both Web3 and Web2.
