Today I had a moment to reflect on cryptocurrency as a direction of information technology development, and the following thoughts came to my mind:
Let's start with the fact that the blockchain system itself currently serves as a good data protector, being a decentralized thing that is not controlled by any specific groups of people capable of leaking user data. But this is already known to everyone; it can be learned in Binance Academy through the courses. However, what really interests me is the position of blockchain in the perspective of 20-30 years. Right now, hashing allows for data protection, being a one-way operation, a hash is very difficult to decipher, etc., but this is the case now.
Quantum computers (in the development of which Microsoft, Google, and other giants are actively investing money) use qubits in computational processes, allowing them to perform calculations not in 0/1, but in 0/1/01 format, i.e., they can perform operations much faster than regular PCs (the methodology of quantum computers is also publicly available; you can familiarize yourself with it).
And if we are heading towards ensuring the availability of quantum PCs on par with standard ones, the moment is very close when hash operations in blockchain can be deciphered as quickly as Caesar's cipher. And when malefactors gain access to such technologies, will it not threaten one of the foundations of cryptocurrency - security? I have no doubt that I am not alone in my thoughts, and developers are aware of modern technological progress, but throughout history, attacks have developed faster than defenses.
If my thoughts on this matter are confirmed at the lower level of development (since I am not familiar with blockchain at the dev level), then the technology may (and should) undergo significant changes in its very structure in the near future. The use of quantum encryption offers an increase in computing power (that is, an increase in the number of transactions processed), the creation of new security systems, protection against unauthorized access to the data transmission process, and other interesting innovations that are the main directions of blockchain development as a technology. The only question is who will gain access to quantum computing technology faster: private developers or hacker organizations? For ordinary people, users of web3, blockchain, cryptocurrency, and similar things, the role of a spectator has been assigned here.
Sometimes my thoughts lead me to not the most favorable predictions of the directions of events. Therefore, it is so important, on one hand, to develop as much as possible in all the more or less used areas, but on the other hand - the less you know, the better you sleep. But knowledge allows you to be prepared for a greater number of outcomes, opens your eyes where others walk in the dark, stumbling and falling. Knowledge itself will not help you avoid stumbling; it depends on how you will walk, but it will open your eyes to the path you are taking, the path the world is taking.
In my opinion on this matter, the crypto world is on the right path, where everyone depends only on themselves, where in case of a mistake, you can only blame yourself, which will allow you to analyze your behavior and avoid repeating mistakes in the future. Quantum technologies indeed may have a future, as long as they are not rolled back by orders from above...
If you agree on something - hit like, it makes me happy, and it's free for you. If you have counter thoughts on this matter - the comments are open, I love to philosophize and discuss interesting questions with interesting interlocutors. Wishing everyone a good mood and useful thoughts! :3
