Block #4313 - reward only 17.4696629 DCR why so few? Can anyone explain? https://mainnet.decred.org/block/0000000000001f75a9c5e4fd85e1fa4cd8fcadb1502b729df65972dc7c5a908a
Reward is proportional to the number of votes in the block. If someone fails to vote, they lose all their PoS reward and the PoW miner loses a fraction of their reward. The penalty to the PoW miner is to incentivize them to maintain high network connectivity and to discourage them from manipulating the voting on blocks by only including certain votes that vote in the way they prefer.
