Transaction Order of Execution - Same Gas

Question

I'm scratching my head here regarding transaction order of execution. Reference to these posts:

Order of transactions in the same block

What is the default ordering of transactions during mining?

• Let's say we have two accounts A and B
• Both accounts sends the same kind of transaction with the exact same gas fee
• Which transaction gets executed first?
• Is it random?
• Does the timestamp play a role?
• Or something else?

Answer 1

Both the order of transactions between different accounts and the fact if a transaction is even included, are decided by the miner. The miner could even decide to include a lower gasPrice insted of a higher one. The only limitation, as explained in the first post you refered, is that transactions from the same account are processed in nonce order.
