Ask HN: What Is the “HN” of “Web3”, Crypto, DeFi, NFT, etc

These technologies have mindshare and will be part of our world’s future. As an engineer, where can I read about these technologies discussed regularly, so I can learn & understand through exposure? Is HN that venue? (If not, why not? What are the boundaries of our bubble here). I’m interested in the tech/practical applications, as opposed to the hype/emotion.
