Debit card – Need to charge currency to fiat card

This is a cry for help! I know I'm new to the subject of cryptography, since I invested in it just a couple of months ago,
But by God I did not expect to have much money and no place to spend them! I live in the United Kingdom, and not just a regular
The shop where I tend to buy products or services, whether on the web or in my city, accepts cryptography directly. I need a
Advice from you, about whether there is even a service that allows me to load all my cryptography in GBP or EUR
And I use it on my debit card, so I can have a real way to spend it?

cryptography – Schnorr Fiat Shamir Transformation

In the Schnorr identity protocol, we can transform the interactive ZKP into a non-interactive one by replacing the verifier function (that is, providing a random challenge value) with a hash function that uses the encrypted function of the tester as input.

s = r + e * x

where:
e = H (r * G)

Validation works by ensuring:

sG == R + e * P

where:
R = r * G

Suppose that in this non-interactive model, the tester chooses a r value in advanceand run R Through the hash function to determine its corresponding my to digest. Suppose that the prover is malicious and seeks to trick a verifier into accepting a Schnorr signature without knowing the private key X. If the prover uses this my value when the signature is built, while an arbitrary is also selected s value, they could go back sG = rG-eP. As the author knows R, e and P, it seems that they could convince a verifier that the signature is valid, without needing to know the private key. What prevents this from happening?

exchange – Cryptographic credit / debit card provider – Crypto to Fiat process

How does your crypto credit / debit card provider organize its cryptographic exchange process to fiat?

I thought that they would manually exchange crypto with fiat in exchanges through a bot. However, this would not be instantaneous, right? Even if they used an exchange that allows "market operations" and a robot that performs the exchange, I can not see how it would be instantaneous.

Any idea how the card providers solved the problem?

EDIT: Could it be that they buy cryptography in bulk, so there is no exchange at the moment (probably OTC)?

automation – Automated transfer of FIAT to the bank from Exchange

This would vary widely according to the exchange. The transfer and trade of BTC can almost be automated through the larger exchange APIs. Fiat withdrawals could be possible, but I do not remember seeing any API for that recently. Your best option would be to get in touch with the exchanges and ask about it, as I suspect that it is a feature that is available "on demand" for larger customers, and that they might be willing to support you in that.
