HOPR is a privacy-preserving messaging protocol that incentivizes users to participate in the network. It provides privacy by relaying messages via several relay nodes (hops) to the recipient. Relay nodes are getting paid via payment channels for their services.
In contrast to Whisper which has been developed for broadcasting (and does not guarantee that a message is reaching a particular recipient) HOPR is built for point-to-point communication. This makes sense for use cases such as P2P chat apps, interfacing a PoS node or other transactions that should be privacy-preserving also on network level.
We have a working PoC and are asking for this grant to make HOPR more useful and user-friendly.
