who would you trust enough to give the private keys to $200m?

You can break the key up into pieces, so no one person holds the whole key, or use something like Shamir's Secret Sharing algorithm.

They did that here. They lost 1 part of the key and now can't access anything.

This illustrates why, through extensive experience and interaction with "blockchain" folks, I want nothing to do with the entire crypto industry. It attracts the very worst of the worst. I'm sure there are plenty of honest companies trying their best to legitimize this stuff. But the vast, vast majority of it is just outright plundering and fraud by the most vile people on earth.

People have said the same about the Internet in the past have they not?

I thought it was obvious, but if you do this, you include redundancy.

Maybe. But the immediately apparent, world changing utility of the internet couldn’t be denied. It didn’t need “evangelizers”, it took off because it was a useful technology. I’ve yet to be convinced in the same way of a single legitimate non-speculatory use for crypto.

Wait... What the??? Quote "BitGrail lost $170 million worth of Nano XRB tokens because... the checks for whether you had a sufficient balance to withdraw were only implemented as client-side JavaScript "

I remember a number of early e-commerce sites that put item prices in HTML forms. So craft your own POST, and name your own price.

Recently seen the price listed/editable in the URL on a checkout form page.

Yes, seen this once before, where the shipping price was calculated client side, then sent to the server with no validation. You could craft a request with a negative value and get the price down to a cent for the entire cart!

At least in e-commerce, you can always send an email to the customer explaining the mistake, and cancel the order...
