Title: Confirmation Times Post by: fwho on February 24, 2013, 06:04:15 AM I am posting this here because, well I should probably know the answer but I dont. Im still fairly new to bitcoin.
Anyways, I sent two transactions within 4 seconds of each other. The first took 16 minutes to confirm, the second is still unconfirmed 1.5hrs later. And I am noticing this with other transactions as well. One took only 3 min to confirm, while I have others that are still unconfirmed after over 165 min. One that is still unconfirmed even said Network Propagation 107% (now at 0%). So, what is going on here? Why do some confirm almost instantly, and others seemingly not at all?

Title: Re: Confirmation Times Post by: fwho on February 24, 2013, 06:22:12 AM Yes AND no.
I left the default on for the first few transactions, had a slow one and turned it off for awhile. Had even more slow ones, turned it back on. And all of my unconfirmed just went through at the same time as I was typing that. Like 7 of them.

Chances are what happens is that your second transaction used the change that was output back to you from the first transaction. When you spend a coin that was only recently received (even if it came from your own wallet), then the bitcoin network treats that transaction different from a coin that is about a day or more old. It does this to protect the network from griefing that occurs. If it didn't do this, then a user could cheaply send funds back and forth from a single wallet at little cost yet at the same time impose a significant cost to the rest of the network in bandwidth and storage costs. If that is what happened then a higher fee on the second transaction might have helped a little. Also, you can split up a coin yourself in advance so that when you do spend there are multiple older coins that can be chosen for spending without having to re-spend the change output from a recent transaction.
