>>14Yeah, I caught that too, and it was the first I had heard about it. Apparently, the network can only make three or four confirmed transactions a second, and since no one wants to upgrade*, the solution is to just allow zero-confirmation transactions. Then, if I am understanding correctly, the user can just pay a larger fee to have those coins that were just spent sent to a different address so it gets confirms faster than the first transaction. That only works for credit cards because the credit card company can decline to reverse charges. It's pretty stupid to allow this for shitcoin. At the very least, it will do nothing to solve the problem of day-long waits for confirmation, since no merchant would be stupid enough to allow this, and customers would have to be put in Faraday cages until confirmation still.

* I looked into it, and the bitcointalk
forum and the Reddit group /r/bitcoin are the two largest groups for this, and they ban any discussion of changing the protocol, saying it would be an altcoin. This is extremely strange, since apparently, the root of this bottleneck is caused by a hack that was intended to be lifted later on. Never underestimate how much forum moderators like to play God, I guess.
