The options available today for interactive (low latency) communication with privacy guarantees are very limited. Solutions developed to date have focused on the traditional web model of a single trusted origin publisher for data (as opposed to content-addressed systems where data may be replicated in advance), and have drawbacks both in their incurred latency and threat model. 

We are soliciting proposals to explore and develop viable mechanisms for reader-private communications under the hypothesis that it is possible to design a scalable system that does not sacrifice latency for privacy. The solutions proposed for this RFP will address our published open problem on private retrieval. 

This request for proposals is intended to fund the research and development of interactive private communication mechanisms, with the goal of creating deployable prototypes. We are particularly excited to develop work that can be applied in the contexts of libp2p, IPFS, and Filecoin, but we are considering all projects which can be generalized to content-addressed data
