I heard that Quantum Computer can destroy bitcoin.
Is it possible?
Yes, you are correct it can because it uses quantum-mechanical phenomena, such as superposition and entanglement, and after research I got to know that they are using AI for superposition in which it can choose both on and off (1 and 0) while computing and correct the errors and configure the private keys through public on its own!
I can see that most of people are talking about SHA-256 algorithm
SHA-256 algorithm generates an
almost-unique, fixed size 256-bit hash
There might be a solution for this also I have heard about this Blockchain Security system
http://blockshield.io/ which can block even AI.
