Vitalik Buterin, the founder of Ethereum, made headlines earlier this year when he argued that DPoS creates incentives for witnesses to form cartels and bribe voters.

Then Vitalik Buterin said the truth earlier this year. Bribing voters is a real thing. At least on the Steem blockchain.

Convince me they're wrong, using Hive as the working example...

Some witnesses are already offered votes for voting for them on the Steem blockchain. Probably the same thing is going on on the Hive blockchain, but to be honest, I do not even want to see it.
