Hi folks,

I've been reading up on the bitcoin protocol non-stop and have a couple of questions that I haven't been able to answer:

• When a node assembles a new block to mine, how does it determine which transactions from the list of unconfirmed transactions to include in that block that it will mine?
• When a node assembles a new block to mine, does the order of the transactions that it picks to be in the new block matter?  My guess is that it should but I couldn't find any literature confirming or denying that.  Can anyone explain?

Thank you!
Konstantin
