In 10 years from now a quantum computer will have sufficient computation power to give a 51% attack on the bitcoin network.
Please discuss.
Please discuss.
In 10 years Bitcoin+blockchain:
1.Won't exist.
2.Will improve to a level,in which quantum computers won't be a threat,they could even help.
Let's hope that the second option will happen.
This topic has been discussed 100 times before,so it's pointless to ask the same questions again and again.
No, albeit Bitcoin can be improved to be even more resistant, it is of my knowledge that Bitcoin right now is safe, IF people stick to using Bitcoin addresses ONCE, and only ONCE.
Once the proposed soft fork or whatever gets passed, then even this won't be as critical, but as it has always been since the beginning, if you want to be safe, use your Bitcoin address only once, then move on to the next one.
This is unrelated to the 51% attack, that doesn't even need to break the encryption, or use quantum computing.
