Well, my $1 transaction has been confirmed with 0 fee - so that's cool. Not going to make that a practice though. Curious to see whatever happens with that $0.01 transactions, still stuck unconfirmed at 0% propagation and only 1 node.

CP1: Even with a payment processor like Bitpay, if the money is unconfirmed it will never make it into the ledger.

Sonny: Someone from another forum posted:

"blockchain.info can't undo transactions. they can only let you attempt to double spend them and stop rebroadcasting the old transactions so they might disappear from the network before they get included in a block, but I'm not sure if this happens."

So, will blockchain indeed stop broadcasting these after a few days?

If not, I found a potential solution here, which is something that looks like a real pain to deal with:

OK, I'll wait it out.

I am also looking at this from a merchant perspective, the practicality of accepting bitcoin for in-store customers. I can't have a customer wait around for hours for confirmations. They could leave my store with my merchandise, and keep thier money, all by sending me a 0 fees with their transaction. I would have no way of forcing a fee on their wallet.

That is what I was thinking, but how to stop the tx of this? Do I have to go through the rigamarole of downloading my blockchain.info wallet into QT, deleting the transactions, then re-uploading it?

I am testing out some scenarios with micro payments, for instance sending 0 fee micro-transactions. I sent one for $0.01 and one for $1.00 both with 0 fees. Now, I can no longer send from that wallet address, even though I have .14 BTC in the wallet. I get a message:

"This transaction cannot be sent because there are insufficent funds available. This may be due to additional miners fees or unconfirmed transactions.

The transaction can either be cancelled. Or the amount to send can be adjusted to match the maximum amount available to send."

So, my 2 unconfirmed transactions are stuck in there, which are causing this.

How do I recover from this?
