Nonetheless, becoming quantum-resistant, at least in terms of signature algorithms, is on Bitcoins roadmap as a necessary step, he added.

Nonetheless, becoming quantum-resistant, at least in terms of signature algorithms, is on Bitcoins roadmap as a necessary step, he added.
He makes it sound so easy.
Post-quantum cryptography calls for massively larger key and signature sizes. For example, a Lamport signature scheme would make transactions hundreds of times larger than now. It would be horrible for scaling.
Don't even get me started on the millions of lost or otherwise vulnerable outputs that won't be made quantum-safe by implementing a new algorithm.
As per experts, Quantum computers really becoming incredibly powerful, and it is more faster than Blockchain, but it is also believe that it will not break the blockchain industry, it will be hard to tell that right now and they can't see no real threat. If this will happen, it will count few decades before we can tell, so there is nothing to worry about for now.
