BlockCDN (CDN - content delivery network) is an interesting project mixing the CDN concept with the blockchain technology. CDN network are really expensive to maintain and to purchase, but what if the entire world could share his free bandwidth and storage?
A content delivery network is a globally distributed network of "proxy" servers located all over the world in dedicated machines. With a CDN is possible to serve everyday content to the final user with high availability and high performance. With the blockchain technology is possible to guarantee integrity, authenticity and uptime of the everyday content. Mixing those concepts, allow users to save money by purchasing BlockCDN instead of expensive standalone CDN, allow users to "loan" his idle equipment such as PC, internet, tablet, smartphone etc. and earn money.
