Replace by fee
One problem with using fees to control congestion is that the fee to get to the front of the queue might change after you made a payment. Bitcoin Core has a brilliant solution to this problem — allow people to mark their payments as changeable after they’ve been sent, up until they appear in the block chain. The stated intention is to let people adjust the fee paid, but in fact their change also allows people to change the payment to point back to themselves, thus reversing it.
At a stroke, this makes using Bitcoin useless for actually buying things, as you’d have to wait for a buyer’s transaction to appear in the block chain … which from now on can take hours rather than minutes, due to the congestion.
Core’s reasoning for why this is OK goes like this: it’s no big loss because if you hadn’t been waiting for a block before, there was a theoretical risk of payment fraud, which means you weren’t using Bitcoin properly. Thus, making that risk a 100% certainty doesn’t really change anything.
In other words, they don’t recognise that risk management exists and so perceive this change as zero cost.
This protocol change will be released with the next version of Core (0.12), so will activate when the miners upgrade. It was massively condemned by the entire Bitcoin community but the remaining Bitcoin Core developers don’t care what other people think, so the change will happen.
If that didn’t convince you Bitcoin has serious problems, nothing will. How many people would think bitcoins are worth hundreds of dollars each when you soon won’t be able to use them in actual shops?« Back to Glossary Index
