> The Web3 approach of having to trust nobody is not really practical to begin with. Blockchains are slow and expensive. I generally agree, for almost all uses blockchains are pretty bad. But it has, so far, been an eventually consistent global write-only data store where reads have 100% uptime. I don't want a service layer on blockchain, don't want to be using the blockchain to transact, but if there's some small modicum of write-once globally-read-many datum (such as oh say, a cryptographic token I can use to sign things to prove my identity) where blockchain actually seems like a good match. The slow and expensive isn't a problem, if all I'm doing is proving an identity I made a long time ago. I'm not super worried about people verifying me using a bad blockchain. These systems should be self-verifying & diverging for too long should trip systems.
