There are several oversimplifications to watch out, but still interesting.
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.
