Use existing tools to increase privacy in Raiden #8

Closed czepluch closed 4 years ago

Prize Title

Best hack that increases privacy of on-chain transactions in Raiden

Prize Bounty

The best submission will be rewarded with 3,000 USD worth of RDN (at the time of creating the Gitcoin bounty).

Challenge Description

Raiden aims to make payments for dApps easy by enabling fast and cheap off-chain transfers. Raiden is especially useful for micro payments or all kinds of streaming, paywall or IoT payments. Furthermore, Raiden offers pseudo anonymous / private transfers by only interacting with the blockchain for opening and closing channels. This means that everything that happens in between is not submitted to a public blockchain for everyone to inspect.

We would like to see hacks that focus on improving privacy of the interactions with the public blockchain that are needed to open and close Raiden channels.

An example could be to utilize a technology like tornado.cash to mask the origin of funds for a Raiden account. Another option could be to investigate if channel topologies in Raiden could be setup in a way that improve privacy when settlement of channels take place.
