True, but blockchains only help if you have multiple copies of the chain. With one copy, there’s nothing stoping the owner from rewriting history. It’s why companies saying they’re “investing in blockchains” means nothing; DB replication/redundancy doesn’t stop a malicious owner. So unless we’re all gonna start storing copies of HN’s database(s) on our home computers and phones, a blockchain won’t help stop abuse. Speaking of which, how big would said copies be?
