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
  • Although AAL promises to resolve this problem by proposing compatibility to x86 architecture, it is of paramount importance to consider the deficiencies of EVM and solidity to be one and the same as Qtum’s.
