yes of course that would be a fairly simple way to solve... I'm just curious that I've not heard about any blockchains doing so, especially with all of the Quantum hype... cryptos love to ride hype trains...

But seriously, it would make more sense to implement quantum resistant cryptography before a quantum computer is created than after. Although I suppose if the practice had developed very far we'd already be using them for everything.

Not that I think practical quantum computing is so close... but, ya never know.
