I'm so excited to present my work on -wide hashtag federation, search, and subscription at .

The recording will be available later, but if you're interested in enabling a global consistent view on hashtags, know stuff about DHTs or relays, you can have a look at the paper: git.orlives.de/schmittlauch/pa

Please contact me about any questions, remarks or other feedback!

So here's a TL;DR:

The problem about the current state of hashtags in the fediverse is that users have a fragmented view on posts, depending on their instance. Some posts containing a hashtag never reach your own instance, so you won't see it. This is bad for decentralisation and coordination.

I plan to throw some additional P2P stuff at the fediverse: All instances are distributing the responsibility for relaying or storing posts (just their IDs) among themselves using a Distributed Hash Table. ->

Now we a defined entities in the network where we can subscribe to posts of a hashtag, query their history and send posts to when publishing.

I considered load balancing, redundancy and security concerns. My solutions may not be perfect, but they're the best I could have come up with.
