WAKU-RLN-RELAY: Privacy-Preserving Peer-to-Peer Economic Spam Protection. (arXiv:2207.00117v1 [cs.CR])

In this paper, we propose WAKU-RLN-RELAY as a spam-protected gossip-based
routing protocol that can run in heterogeneous networks. It features a
privacy-preserving peer-to-peer (p2p) economic spam protection mechanism.
WAKU-RLN-RELAY addresses the performance and privacy issues of the
state-of-the-art p2p spam prevention techniques including peer scoring utilized
by libp2p, and proof-of-work used by e.g., Whisper, the p2p messaging layer of
Ethereum. In WAKU-RLN-RELAY, spam protection works by limiting the messaging
rate of each network participant. Rate violation is disincentivized since it …
