Hey HN -- I know it's a controversial topic, so hoping it doesn't devolve into a 'blockchain good/ blockchain bad' debate, but here's the start of a book we're working on that teaches the actual technical skills for Solidity and smart contract programming, not just the higher level "click here and now you have an NFT" stuff that we see around a lot. Feedback appreciated! We've only got four chapters for now, but will add more if it's useful to people.
