CESS Network is an underlying data infrastructure built for Web3 data services. It leverages decentralized storage, supported by the CESS layer-1 blockchain, and supplemented by CDN services. CESS aims to provide full-stack data services for large-scale commercial enterprises in Web3 and Web2 application protocols. Through the CESS system, distributed storage, transmission, and data processing software services are integrated to form a robust resource system. For Web3 application protocols (B-end clients), CESS offers storage service, CDN services, public chain payment transactions, distribution, and data processing while charging corresponding tokens as gas fees and data service fees based on usage.
