I think fake iris scanning is the least of the concerns here. The big problem, and likely reason this will fail, is there’s nothing preventing you from selling your account for a small fee after getting your initial scan to set it up. And that’s likely exactly what will happen, because they’re onboarding users in poor countries first. These users don’t give a shit about world coin, they’re simply lining up and being scanned to make a bit of easy money.

The premise is that you can make spam filtering and bot filtering and circles of trust work if you have a finite amount of accounts. Currently on the internet there are infinite accounts. If there's only a billion accounts, filtering becomes much easier.

And all the poor people who sold their accounts when that seemed to have no cost for $50 (which is real money) are locked out of the internet forever

No idea how world coin is supposed to work.. but couldn’t they get their account back by scanning their iris again? Like, I’m guessing you’re not supposed to have to scan your iris every time you use your account. But can’t the iris be like a “I forgot my password” mechanism?

[HWR_14]

AFAIK, nope. If that was the case there would be no point in buying anyone's account. If you stored value in it they could always use their iris to get into it.

Yeah, it’s a cool idea, even though it creeps me out.

But why do you need a coin for that? If you have centralised accounts you may as well have a centralised ledger.

On the other hand, if you decentralise account creation - let me tell about my friend, the virtual iris scanner powered by /dev/random
