>it's possible of course it is, just block validation time is a bitch when you go shopping.
it's not needed with the thing i'm talking about

i don't remember exactly but it involves you sending crypto to an address that nobody can withdraw from (same as loading a channel in lightning network) but the address has a timelock, after which you can take back the crypto

when you pay for something you give a transaction to the vendor that HE signs and MAY broadcast to the network, the transaction sends crypto back to yourself and to the vendor.

that way the transaction is instant and trustless, the vendor knows that only he can move the crypto from the address and you know that if he doesn't broadcast the transaction before the deadline you get a full refund.

i forget the details (or what it's called) but it's possible on-chain without lightning network.

>it's very simple and straightforward
segwit and the concept of block weight was not worth it compared to just increasing the block size. also introduces the risk of everybody scrapping the segregated data, which makes it impossible to verify the full chain of transaction back to when it was mined. the hashes will be right but you don't know if the data that made those hashes are right. it's been 2 years since i thought about these things so i may not remember exactly and i don't have my saved reference links with me
