Indeed, the world of cyptocurrency/blockchain research has many ground breaking papers and news are often real time, even crypto news aggregator can't keep up with it. HN crowd refuses to care about it because of bad taste of crypto in general.
It's a bummer because zkRollups and their ilk in particular are flat out amazing new cryptographic constructions, but because they weren't developed by Schneier or Rivest or DJB, the wider programming industry is ignoring them.
Do you have recommendations on where to find this stuff?
I agree that there seems to be a lot of interesting work going on and the ideas of decentralized finance have a lot of potential. At the moment it really is hard to cut through the noise though and from what I can find just searching for an afternoon it looks like a minefield. I'm hoping that the bad stuff will all fade away and something useful will remain.
You can join each crypto's subreddits/youtube/twitter to find more. This is basically what crypto news aggregator do. They just read articles/watch youtube videos all day.
