Quantum computers will be integrated into the blockchain system. In this case, the existing encryption may change. Because enormous processing powers or super-superchargers may require the system to change. The most important thing for Bitcoin is encryption and speed.
What does it mean to introduce quantum computers into a locking system?
As for encryption, I agree, encryption will change. But the existing encryption can only change to some post quantum public key cryptographic system.
The fact is, all post quantum systems require more computing resources than the existing elliptic encryption.
That's why I don't understand how I can increase the speed. After all, today if you buy a cup of coffee for bitcoin, it will become cold while the calculation is done.
How can I increase the speed in the future?
