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.

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. …

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…
