The "proof of space" Chia cryptocurrency: https://news.ycombinator.com/item?id=27009843
I'm starting to wonder what'll occur first: the bubble popping or the whole hardware market coming to a standstill because of 16 different "proof of xyz" schemes. I cannot wait for internet connections to become unusable after a currency introduces "proof of bandwidth".
In all seriousness, I'm expecting the former. With current trends, the Chia currency is going to be "farming" so much storage that reward per TB will drop below the breakeven point for computing more "plots" to farm, or for even keeping existing "plots" online and taking up storage. It's just a bit hard to predict where that point is since Chia itself is just getting started and has yet to be extensively traded.
