At any rate proof of stake and delegated proof of stake is different.
This is what the Whitepaper says about PoB The Concept
Hive also aims to overcome mainstream adoption shortcomings in blockchain technology and content publishing by improving on their accessibility. It leverages the coined Proof-of-Brain (PoB) concept by distributing a portion of the inflation to content creators and consumers. To earn without financial investment, individuals partake in a wide range of activities. Those include blogging, participating in discussions, curating others, building and engaging with dapps, playing games and more; their limits are only constrained by their own imagination to further the decentralization of the system. All content is always readily-available on the blockchain and retains its original integrity.

Delegated Proof of Stake (DPoS) is the consensus algorithm behind Hive. In a DPoS algorithm, the selection of block producers (called ’witnesses’ on Hive) and all other consensus-based functions are decided based on the weight of staked funds supporting them. Stakeholders hold the highest prominence in DPoS .DPoS consensus is considered to be the most inclusive and the least centralized of all the blockchain protocols.2 DPoS was first invented by Dan Larimer as a functional alternative to the Proof of Work system introduced with Bitcoin. Other prominent DPoS blockchains include BitShares and EOS; they are originally based on Larimer’s Graphene framework.
