   A developer is choosing a consensus mechanism for a new public blockchain that aims to be energy-efficient and secure against a 51% attack. They are considering proof of stake (PoS) and delegated proof of stake (DPoS). Which trade-off is most important to consider?

   • APoS is always more secure than DPoS because it uses more computational work.
   • BPoS is less secure than DPoS because it allows anyone to become a validator.
   • CDPoS is more energy-efficient than PoS because it does not require any token staking.
   • DPoS requires validators to lock up tokens, while DPoS relies on a small set of elected delegates, which can reduce decentralization.
