MetaMask is one of the most used crypto wallets, but it offers much more than that. With its help, we have the possibility to digitally sign data structures, which can be utilized in many different ways. One option is to use MetaMask for authenticating our users. In this case, we…

ActivityPub is an open, distributed social network protocol standardized by the World Wide Web Consortium. Its first version was released in 2018, so it is not new. …

Have you ever thought about how money is created? Well, typically, it is made out of nothing by banks. When someone takes out a loan, the bank adds the borrowed money to the amount already recorded in its database for the bank account. So if $100 was already present in…

I admit that the title may seem strange at first. Why are Brain-Computer Interfaces among humanity’s most important innovations ever made? Just consider fusion energy, which could provide us with infinite energy. Wouldn’t an infinite amount of energy be more critical? But do we need an infinite amount of energy…

Spoken language is only the first step because anything can be tokenized — Large Language Models (LLMs), such as ChatGPT, have made a significant impact, although they have some very strong limitations. One of these limitations is that these models are prewired. This means they are trained on a big set of documents, so they have a very big knowledge, but they cannot…

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. This is why I built zk-merkle-tree, a JavaScript library…

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…
