Optimization of TPS
  Achieved compact block logic
  Removed 1 execution of tx out of 2: no execution at “deliverTx”, only execute at “commit”
  When transmitting over p2p network, “flush” time is reduced from 100ms to 10ms, “send/recv” rate is improved from 51200 to 51200x100
  “gossip data / vote” sleep time is reduced from 100ms to 10ms
