If you run a web shop, a web hosting business or you offer VPS rental etc. you might want to use Cashu to improve your customer's privacy and avoid having to handle and store toxic data.

Here is how a VPS provider could use Cashu to unlink payments from purchases:

- Costumer logs in

- Charges their account to obtain Ecash minted by your own service (for example Bitcoin in, Ecash out or Fiat in, Ecash out)

- Ecash appears as the user's balance

- User uses Ecash to rent a VPS, paying it back to you

We made everything so easy that this can be integrated into your website using a simple wallet library. From the user's perspective, nothing changes compared to a classical top-up and purchase experience.

That way, you wouldn't need to know which credit card transaction belongs to which VPS purchase. No custodial risk eitther, you're the service provider.

Win win.

For what it's worth, this is almost how the Wasabi coinjoin coordination service works, so this model is proven with 7+ years of deployment.

It's magical tech, use it!

I vaguely recall reading something along the lines of Apple using (or maybe just proposing) tech like this for their VPN-like private browsing product.

Google uses RSA blind signatures it for their VPN to achieve exactly this, to decouple of the VPN use from the user account.
