This is an attempted coup alright, but it's from idiot miners who want a bigger slice of a smaller pie. If we cave on this, they will never allow our network to become competitive enough to disrupt the banksters.
Bloating the blockchain to DOA levels will disrupt bitcoin, not the banksters.
Besides, 8mb blocks, or even 80mb blocks, aren't enough to scale to such levels. You'd need enormous storage (and bandwidth) per day to compete with the volume of banks and credit cards.
No, not enormous. Realistic amounts which are available today is enough. Also ever heard about pruning? Not every node has to have an entire copy, I'm sure the NSA will be glad to assist in keeping an entire copy for you. Including every government agency in the world.
Hey, spoiler alert, the blocks won't be 8MB from the start, they will be as big as the miners want them to be.
