PolderCast: P2P Topic-based Pub/Sub

This is an OCaml implementation of PolderCast, a P2P topic-based pub/sub protocol described in the paper PolderCast: Fast, Robust, and Scalable Architecture for P2P Topic-Based Pub/Sub

It relies on three different gossip protocols:

• Random Peer Sampling, to find random nodes in the network. See the P2p_cyclonmodule.
• Clustering, to find nodes with overlapping subscriptions. See the P2p_vicinity module.
• Dissemination, for the dissemination of messages within a topic. See the P2p_ringcast module.

Privacy

PolderCast, as specified in the paper, employs VICINITY for clustering, and transmits full node subscription profiles in the clear. See BLIP for a privacy mechanism that transmits subscriptions as randomized Bloom filters instead, and BFPSI, a Bloom filter-based Private Set Intersection protocol to determine common subscriptions of two nodes.
