CacheCash Experiment on EdgeNet

CacheCash provides a service in which interested users run caches, and they are incentivised to participate by receiving a crypto-currency (Cachecoin) in exchange for serving content to other users.





Additional Info

There are several ways to look at the innovative aspects of this work. First, the innovative technology we deploy has never been tried at a scale even remotely approaching this. It is unknown how the cryptographic techniques for distributing content securely in a way that economically incentivises cheating will work given the latency, non-transitive connectivity, and scalability constraints of the internet. Further, our effort to use real world software distributed to real world users will provide a basis for understanding how such technology will work in practice and at scale. To date, most efforts around building distributed data delivery have focused primarily on data storage or on trusted nodes that deliver content. The expected impact of the CacheCash experiment will be to push the boundaries more toward low latency and bandwidth, which are highly valued in the CDN space.

Enduser Relevance

CacheCash established a broader network at the edge than conventional CDNs. The measurement data gathered throughout this experiment demonstrated that CacheCash is a promising framework for next generation CDN infrastructures.
