Pros

Different from the coinstake in PoS, block miners of PoA are rewarded in the coinbase for simplicity. The contract refund, which is generated by the contract execution in Qtum, should be added to the coinbase as well. Therefore, the coinbase in PoA contains one or more outputs. The first one is paid to the block miner and its amount equals to the sum of transaction fees and block subsidy, while others are contract refund outputs.

Cons

My understanding is that plasma consists of a "Supreme Court" smart contract and a side chain implementation that interacts with it... Should the plasma smart contract be compatible with the evm for Qtum? Unless I'm mistaken I would say that it's highly possible
