If two conflicting transactions A → B and A → C are both broadcast almost simultaneously from different nodes, what determines which one will eventually end up in the block chain? (check all that apply)
The key to this question is that it is really just miner's choice in case of double spending.
| The transaction that reaches the majority of nodes first will win | Wrong |
| The transaction that was broadcast first will win | Wrong |
| The miner who finds the next block will likely resolve the tie by including one of the transactions in the block | Correct |
| Each node has its own version of the block chain containing the transaction that it heard about first | Wrong |
