Pay securely with an Android smartphone, completely without Google services: This is the plan being developed by the newly founded industry consortium led by the German Volla Systeme GmbH. It is an open-source alternative to Google Play Integrity. This proprietary interface decides on Android smartphones with Google Play services whether banking, government, or wallet apps are allowed to run on a smartphone.
It is kinda insane though that we’ve had public/private keys since the internet started walking and somehow we end up with all these over-complicated or pointless ways to use them.
Decentralized systems are more difficult to understand, and also inconvenient.
Also, very hard to monetize.
Therefore, capitalism converts the issue into walled garden approach. Easy for rubes to use, nobody bats an eye.
