The "blockchain" is just a Merkle tree, like git, which much of the industry uses every day. You build a tree of hash codes by using the hash of the old tree as an input to a new tree. It's a clever data structure and you can do cool things with it. All the blockchain adds to this is a distributed consensus system. This allows deciding what the HEAD of the tree is without needing a central, authoritative server. But honestly, in 99.9% of applications, an authoritative server maintaining HEAD is fine. Pay some law firm or specialized clearing house to do it. The only other aspects of crypto is that it creates a deflationary currency with ruinously-high transaction costs, plus a permanent public record of every transaction. Oh, and starting with MtGox, most of the immitation "banks" have periodically disappeared with everyone's money. This is usually followed by Bitcoin users angrily demanding government fraud investigations. In the meantime, all those proof of work contributions contribute to global warming. Back when Bitcoin was new, it was an adorable technological dystopia that amused libertarians in tech. As long as it was basically real-life science fiction roleplay, it did little enough harm. But then "crypto" promotors started treating it like some kind of timeshare condo scam, and started advertising heavily to elderly non-technical users. And all I have to say to that is, if you don't want to get treated like a timeshare scammer, don't act like one.
