The idea of Delegated Proof of Stake is that the cryptocurrencies holders vote on a selection of 101 delegates who create new blocks in the blockchain and collect block rewards. Each round of consensus consists of 101 blocks with each delegate assigned one block forge. If a delegate is unable to forge their assigned block, the activity in that block is moved to the next block.
Because of the low number of block producers, DPoS protocol has slipped into losing its decentralization for throughput which is in a way losing the basic idea of cryptocurrencies.
