The problem identified of connecting an individual to the key is valid. But if a multi-factor identity token is used to sign a message, then that moves the repudiation back to existing law (lost/stolen token claim, etc.) vice a technological exploit.
The more I ponder this, the more I think that a nuance is being missed. There is value in efforts to establish non-repudiation, but I agree that there are limits. It is reasonable to assert that the holder of a particular key signed the message.
How would this work on chain? Would this end up being a purchase of “tokens” that have no cash value? (I’m all of one week into learning this, so pardon the question if I’m too off base.)
@3 Not sure the best way to submit a feature request, but the Mac app really needs a "back" button. If you are viewing "latest" and look at someone's profile, there is no easy way to get back to where you were. Clicking home then latest is close.
I used buybsv a couple days ago and it “cost” about 10% to convert USD using a credit card. 2 cards were rejected outright and the final one sent me a fraud alert.
Sounds intriguing, but on-boarding needs to be easy. Currently it is kind of a chicken-and-egg sort of thing. Getting some BSV initially isn't as easy as it needs to be. Twetch gives you one message for free, but for more you need to fund a wallet.
What is the best (lowest fee) method to convert USD FIAT to BSV? I’m guessing that I would need to pick another coin to purchase first (to enable the trade).
