The single truth center is the blockchain. Without that you have nothing. Git and BitTorrent may not have a single truth center, but they are decentralized and can operate autonomously. Bitcoin cannot. I'd argue it doesn't really solve the generals problem, it just provides a mechanism that can solve it by narrowing the problem down and ignoring some of the ugly edge cases. A true solution to that problem would work in "offline" mode, that is you don't need a persistent link to some authority to ensure you're working with correct information.
