It’s...not breathless, not at all, but still a little gee-whiz despite its reserved tone. It also ignores a few important points, like blockchain technology’s horrendous inefficiency. The savior of the web needs to not gobble up energy at tens of thousands of times the rate that a centralized system does, or we arguably go extinct quicker.
And even if we solve that, there’s also the problem that we haven’t yet found a good use case for blockchains despite ten years of trying. Other than buying hookers and blow and getting rich on a speculation bubble that your barber will ultimately pay the price for.
Even so, cryptographic identity verification is big. A decentralized database that no one owns is big. A robust system for verifying transactions democratically is big. These are all huge technological achievements.
