The most obvious stupid scam ever conceived and they actually managed to hook a bunch of actual corporations
Square Enix, Nickelodeon, Coke, KFC, and more fell for this shit while regular people were laughing about how obvious a con it was.
Really puts into question the capitalist myth of the genius entrepreneur and the idea that these corporate types are rich because they are smart or deserving in some way.
Even this is overselling blockchains, to be honest. There are a variety of far cheaper ways to do distributed trustless consensus, for example CRDTs. You can even run a CRDT-based ledger if you're willing for people to have negative balance. The only thing a blockchain adds is an incredibly expensive clock mechanism to slow the transactions down enough that they can prevent double-spend and enforce positive balances.
