Transaction Scoring and Ordering

Ethereum transactions from the same sender are ordered by nonce. Low nonces need to be included first. If there are two transactions from the same sender and with the same nonce only one of them can be included. We choose the one with higher gas price, but also require that gas price increment is high enough to prevent attacking miners by requiring them to reshuffle/reexecute the queue too often.

Transactions between senders are prioritized using gas price. Higher gas price yields more profits for miners. Additionally we prioritize transactions that originate from our local node (own transactions).
