Databases solve nearly every storage problem, there isn't many problems in computer science where they don't apply.
Blockchains solve only one tiny problem: the double spend problem, or when you need data to show an ownership history, and you specifically don't want to rely on a central authority. Its a strange edge case that doesn't even exist for most money, credit, or transactions today.
You cant build a cryptocurrency without blockchain. So ita certainly more than a strange edge case.
I agree; but what @dessalines@lemmy.ml says still holds true I think. Most transaction should probably use layer 2 solutions such as lightning network and only fall back to the blockchain in cases for dispute or settlement which should be a rather infrequent event compared to transacting.
Lightning network is a scam.
ok, well then replace lightning with payment channels in general then. Why is lightning a scam?
Because you have to trust some huge, centralized nodes which can steal your money, or charge extra fees. So basically a bank.
