cashu is an ethically questionable project, and I think people should bash it to some extent
It's based on deception. All of the technical verbiage , "chaumian eCash", website, documentation, etc -- is all a song and dance, to shroud the fact that it is custodial. Thus, it is a "stair-based elevator", just like custodial lightning.
With cashu, you send real BTC to the mint, and get back only an IOU. The cryptography does NOT help you honor the IOU -- it just hides who owns which IOUs. This is underwhelming to say the least. It is like saying "our stair-based elevator gives you a nice view of the area".
Chaumian mints will probably be used for something, eventually -- but until the lies stop, it is perfectly reasonable for
@1440000bytes to try to destroy the project.
After all, if I had criticized the Lightning Network earlier, we would probably be at $500k per coin today.
I would question the ethics of anyone investing in or shilling cashu -- sorry to say. They are too blasé -- about the truth, about technological excellence, about the Bitcoin ethos, the rugpull risk, etc.
Just my opinion, sorry not sorry
