CDN service

The CDN service is offered by CATA CDN nodes. These nodes still use the bi-centralized design. Now there are only several super nodes maintained by developer community.

A CDN node is a gateway from the Web to the DDC. It can act as a web server and provide content to regural HTTP clients, especially web browsers. Web apps can rely on CDN nodes to serve various assets or can even be hosted completely on the DDC.

CDN nodes address the complexity and slowness of decentralized storage. This is useful both for server-based and server-less apps. All access to stored data should go through a CDN node.A CDN node is a stateless service capable of routing content to and from storage nodes, as well as data replication and caching.
