Shor’s algorithm against the blockchain

Peter Shor and his algorithm Scientists are amazing people, they just can’t live without inventions or discoveries. And then the whole world has to think what to do with these discoveries. For example, atomic energy is as useful as it is dangerous. We have an interesting situation with Shor’s algorithm.

Why does blockchain need shards?

The problem of blockchain scalability Any fast-growing blockchain sooner or later faces the problem of scalability. The decentralization and security of blockchain are ensured by reaching a consensus between nodes and storing all the blockchain data in each node. Just imagine what a huge amount of data is growing every

CRYPTOCURRENCIES ARE REALLY AT RISK
Quantum computers

Whether cryptocurrencies are really at risk of quantum hacking?

The question of whether Bitcoin and other cryptocurrencies based on Bitcoin’s code can resist quantum computing divides the crypto community into two opposing groups. Crypto-enthusiasts continue to believe that cryptocurrencies and Bitcoin, in particular, can resist quantum technologies. Crypto-realists pay much more attention to the issue of quantum safety. Let’s

One important “but”: The Quantum Vulnerability

The most important and interesting about encryption. A series of articles understandable even to non-specialists. There is another important nuance, which concerns encryption algorithms, asymmetric ones in particular. When we talk about the cryptographic robustness of algorithms, we mean cryptanalysis performed through a use of the classical computer. But quantum computers already exist.

The advantages and disadvantages of asymmetric algorithms and hybrid encryption

The most important and interesting about encryption. A series of articles understandable even to non-specialists. In comparing symmetric and asymmetric algorithms, we find out each type has its advantages and disadvantages. Thus, asymmetric encryption algorithms are more “cumbersome” when compared with symmetric ones. If the amount of data is the same, the asymmetric

The Asymmetric Algorithm ECDSA

The most important and interesting about encryption. A series of articles understandable even to non-specialists. We have mentioned in detail, the asymmetric encryption and the RSA algorithm being outdated. We will now talk about another well – known algorithm of asymmetric encryption ECDSA (Elliptic Curve Digital Signature Algorithm). Unlike RSA, ECDSA is based on far

Asymmetric algorithm RSA

The most important and interesting about encryption. A series of articles understandable even to non-specialists. Asymmetric encryption was previously discussed in this article. One of the most recognized asymmetric encryption algorithms is RSA, named after the initials of its creators – Rivest, Shamir, and Adleman. The algorithm was developed since the
