@gabriel Dero is a scam. I did some research on them a couple of years ago and came to conclusion that they don't actually have the technology. They were making extraordinary claims about solving very difficult problems, but there were no documentation, and very little amount of code.
People who were working on the same problems (FHE/ZK) also said that Dero is not what it claims to be.
I haven't heard of Dero for a while, but recently their shills again started to talk about it in various crypto-related chatrooms.
No idea what they are doing now. A vaporware can become real if enough people believe in it, but it will never be good.
