• NASA's Mars helicopter - Ingenuity: research materials

    I was reading a lot about NASA’s Mars helicopter - Ingenuity, so I’ve compiled a list of links: materials and research papers about it. I’m mostly interested in hardware and software - especially in terms on navigation. All of the materials are easily obtained by googling them, so that’s the reason I’m including links to them as well.

  • Web3 is still centralized?

    I’m still distilling what web3 is all about. What’s clear, at least I think, is that it’s a service or multiple services or more generally: a clients, built on top of distributed public ledger - a blockchain. A notable feature of such system is that it’s decentralized - no one owns the blockchain, it’s public, so you’re enabled to write to it whatever you want, without restrictions or fear of being blocked, censored or removed. In my opinion, such systems still suffer from centralization. Not from centralization of database, blockchain in this case, but centralization of clients and web services built on top. In this blog, I’d like to draw some parallels to existing distributed systems with high client centralization.
