You have written that "The introduction of a bullet-proof protocol will make the RAYS network also immune to attacks from quantum computers." And what are the dangers and attacks? Why are quantum computers dangerous?
The quantum computer attacks are the ability of extremely fast computers to overcome the difficulty level of the hash function. The ASIC miners spend a lot of energy to solve a cryptographic problem. At the same time, they spend a lot of energy to solve the cryptographic puzzle. Quantum computers, on the other hand, will be able to solve these puzzles in no time. The bulletproof algorithm is immune to such attacks from quantum proof and the privacy shield cannot be broken by the quantum computers.
