Quantum cryptography(Quantum System)
Escudero points out, "will for all intents and purposes break the strength of public-key cryptography", in spite of the fact that for symmetric encryption algorithms – in which the sender and collector have the same key-, "to secure yourself it is sufficient to simply copy the size of the keys that are as of now used, which is just what bitcoin has done preemptively ".
Also, bitcoin has developed several additional insurance measures. "Later on", says the specialist, "it is absolutely sure that some extra improvements will be presented that will secure not just the new transactions that are completed, yet in addition the history of past transactions stored in the blockchain.
Several methods of how to do it are now referred to, yet how to do it as proficiently as possible is being investigated. There is no rush, and it will surely require several years for these measures to be executed ".
Use the enemy's weapons
Ongoing research by Kazuki Ikeda, from the University of Osaka (Japan), proposes using the weapons of quantum registering to ensure bitcoin, creating quantum bitcoins or qBitcoins.
It would consist of the sender sending quantum cryptographic keys to the collector, something very troublesome, since it implies preserving the properties of the individual photons more than thousands of kilometers. https://quantumsystem.info/
Until this point in time, there are five realized quantum key distribution networks in the United States, Switzerland, Austria, and Japan. China is chipping away at its own massive 2,000-kilometer connect.
Professor Martin-Delgado considers that in actuality q Bitcoin is not a scientific development, and that it is simply a substitution for cryptographic protocols. Also, Víctor Escudero sees it as a still distant possibility. "Quantum key distribution systems have serious shortcomings that make them unreasonable today.
Transmission and gathering systems are expensive, questionable and extravagant. Also, in contrast to other systems, it would possibly be possible to send qbitcoins when it coincides that the sender and the collector are on the web ".
In any case, there is no question that cryptocurrencies can use quantum registering for their potential benefit. "From one perspective, it is an incredible catalyst and a catalyst that is now causing significant advances in other branches of cryptography," says Escudero.
"What's more, for instance, it is as of now possible to make links in which it is unrealistic to block communications without this being distinguished."(Profit Revolution)
