Today, one of the problems with cryptocurrencies like Bitcoin is that it takes quite some time for a transfer to go through and enough confirmations to take place. This really isn't a problem when it comes to inherently slow buying procedures, such as for example ordering something online and receiving it a couple of days later by mail. However, other types of purchases requires a much faster process (for example if you're buying a digital good and want it immediately or if you're buying a physical good and want to leave the store with it right away), and as it is now, cryptocurrencies don't seem suitable for these as it simply takes to long time to confirm the payment and defend against double-spending.
Is this a problem that is inherent with the Blockchain technology, or could purchases go through much, much faster (at least so that they can compete with credit card transfers) given enough resources or faster computers in the future?
