Abstract

A Content Distribution Network (CDN) is a new kind of network to distribute services and content spatially relative to end-users, providing high availability and high performance. The Origin server uses several replicas to reach this goal, but trust issues are present between them and between servers and clients. In this work, we present a proof-of-concept for secure static content delivery (e.g., documents, images) by using Blockchain, a technology with the capability to ensure reliability and trust without a central authority. To test our proposal’s feasibility, we developed a system prototype on the Ethereum private network. The test shows the system’s goodness and the ability to create a new content distribution model over the Internet.
