Implemented in Monero: https://github.com/monero-project/monero/pull/6314

Recently there were some DoS attacks on Monero. Details are mentioned in this blog post: https://sethsimmons.me/posts/moneros-ongoing-network-attack/

I have asked related question in Monero SE to confirm if these attacks could have been avoided without Dandelion: https://monero.stackexchange.com/questions/12599/could-recent-dos-attacks-be-avoided-if-dandelion-was-not-implemented

I have tried few things with dandelion in last few weeks including running v0.16..99 with https://github.com/dandelion-org/bitcoin/tree/dandelion-feature-commits (compile, experiment, check logs etc.)

Tried resolving conflicts to include dandelion in recent code: https://github.com/prayank23/bitcoin/tree/dandelion-test

Consulting few people IRL and online

Nothing works. I give up and I don’t want to live with this everyday that could improve privacy in Bitcoin without Tor or i2p but I cannot contribute. Affects my mental health and other projects. I will close the issue. If anyone really interested to work on this please reopen or check two things:

Dandelion Lite. Don’t want to tag people but AJ is working on it or at least did some research: https://twitter.com/ajtowns/status/1362636875140272130
