Is that really that impractical? With a quick calculation 50 ms time offset would mean about 20 meter difference. You can get that accuracy with NTP over residential internet and a better TCXO could hold that for a day. You could sync clo

That could work, but then the service needs to implement complex non standardized authentication mechanism outside of Passkeys. You will have 14 different services with 15 different options. I don't think that's really user-friend

I don't think that would work either. Let's say I have a new account and a single Passkey in the TPM of PC1. I want to log in from PC2, too. How can I do that? (I know there is some trickery with Bluetooth, but I haven't seen

The enforcement of GDPR is more or less nonexistent for big companies. Even if they get fined, that is just cost of business for them. In the text nothing prevents the manufacturer to stream the vide of your face to their servers all over t

I think that depends on how do you define PII. I suspect the ZKP proof or token is practically unique and related to you, so I could be personal data if you use the definition from GDPR. With ZKP the entity and the original verifier shouldn

Some people argue that it is just for more government surveillance and control, but the government already could access your bank and card transactions and freeze or confiscate your money.

The difference is more a financial or legal thing, than a technical one. From an users' perspective paying with digital Euro would work more-or-less the same as you pay today with card, bank transfer or something based on QR codes. But

It gets interesting when the two system interacts. Friends visiting the US told me that at the POS terminal they had to choose credit card despite paying with a Visa/Mastercard debit card issued by an European bank. By the way, here ba

AFAIK the ECB wants to have both things. Digital Euro being a CBDC could open up a lot of possibilities, but they want an unified payment system, too, and that would be a nice first job for digital Euro.

Not really. Euro cash today is paper / plastic banknotes and metal coins. Your account in the bank is not really cash you own, it is more like the banks liability towards you. If your bank fail, you loose the money you held in the bank

by raron 3mo ago
I theory it should be more. The ECB claims you will be able to hold and spend a (limited amount of) digital euro offline (without internet connection).
18.
by raron 3mo ago
That's interesting argument. Here it is usual to have a daily limit on debit cards. You can not spend more money than that, so a thief can not drain your account. Also many banks give you multiple accounts (you can transfer between the

This. If AMD / Xilinx would publish the documentation what you would need to use their chips, probably very few would use Vivado or ISE.

Maybe that's changes by country, but here bank transfers are basically final and can not be cancelled or recalled. Why would a bank cover your losses from their profits?

Chargebacks exists for (EU style) debit cards, too. It doesn't need to be simple just available, so if the merchant disappears with your money or someone uses your stolen card, there is a way you can get your money back. With bank tran

Wero is just another private company trying get their cut of payment fees. You can do the same thing with SEPA Instant Payment (or some member states outside of the Eurozone have their own similar thing). I don't see why Wero should ex
