I'd love to see some credible reporting on the graveyard of blockchain projects.

So many obviously stupid ideas cropped up on the blockchain in 2021-2022. How many of those are still going concerns?

I guess the problem with blockchain stuff is that often there's no servers to shut down or other clear indication that a project has failed - presumably you can look at on-chain data to see if people have stopped trading various backing tokens, but does trade ever clearly stop or are there always bots exchanging tokens back and forth?

Transactions on a blockchain have a cost, so it's kinda hard to sustain faking usage. Unless they count random bogus blockchains.
