I’m basically a tech writer, but sometimes I write short sci-fi novels. Usually, I write them in my native language. In 2018, I translated one of my novels. Non-native readers liked it, but native English readers find it hard to read. …

Anonymity in voting is one of the basic requirements, but on a public network like a blockchain, it’s not trivial to implement it. Fortunately, the technology of zero-knowledge proofs (ZKP) makes it possible, but unfortunately, ZKP is a very complex technology. …

I’ve started to deal with the technology of zero-knowledge proofs because I was curious if it was possible to create an anonymous, unhackable voting system on the blockchain. Paper-based voting (like the Elections) is a very expensive way of voting. I have no exact data, but it costs billions of…

A JavaScript tutorial — The technology of zero-knowledge proof and especially zk-SNARK is one of the most exciting ones in the field of crypto because of the following reasons: You can prove you have information without revealing it (for example, you can use it for anonymous voting). The proof is small and easy to…

A step-by-step guide to a brand-new website — I started my first blog in 2010. Using WordPress was obvious at that time. It was a good choice because it’s easy to use and has thousands of themes and plugins. WordPress is an amazing engine, but it has its downsides. It is resource-demanding, and there are many WordPress-related vulnerabilities…

Storing data on the blockchain is expensive, so if you need to store a large amount of data on it in the “blockchain style” (in an immutable, permissionless, and distributed way) you have to use an external storage solution. The most common choice is using IPFS, but there are some…

You probably heard about the scandal around Google’s AI, LaMDA. In a nutshell, one of the members of Google’s ethical team claimed that this chatbot is conscious, and it has basic human rights. But is LaMDA really conscious? As the famous GPT-3, LaMDA is also based on transformer architecture. A…

If you are a programmer, you probably use GIT. But have you ever wondered how GIT is working deep inside? I do. Fortunately, you can find many documents on the web about GIT internals. When I read them, I have to realize that GIT is a relatively simple but super…

When I was young, I used to think that if I want to really change the world, I have to do something really big. Something that Einstein did when he published the Theory of Relativity, or Newton, who developed calculus which is the mathematical base of nowadays artificial intelligence. Or…
