Ready for the Post-Quantum, a threat to the current cryptography

Although the end user should not worry about whether the technology is quantum resistant or not, it is the industry and blockchain experts who should prepare . . . before it gets too late!

A few weeks ago Google announced a turning point in quantum computing: the company in Mountain View would reach “quantum supremacy”, creating in fact a computer able to complete calculations, which even the fastest supercomputer in the world could not replicate.

Unlike normal computers, quantum computers use qubits: as the classic bit allows two states, state 0 and state 1, so qubits does, but thanks to the superposition principle, it is possible to combine linearly the two states, increasing exponentially the power and speed of these computers.

PREMISE

In Blockchain encryption it is rather difficult (not to say impossible) to calculate the value of a private key, having only the public one available.
