The technology has existed for many years already, and it has already made 'broader implications', see git. The only thing new about it is that people now call it 'blockchain' instead of a merkle tree. The reason banks and governments don't use better technology to track land titles or whatever other applications is that they're always slow to adopt technology, not because 'blockchain' is a new concept

But this isn't really the case. Both git and blockchain track a history of actions, true, the difference is that in git anyone can rewrite history at any time and there is then no way to agree amongst untrusted parties whose history is the true one. With blockchain, there is. That's the innovation, that's what makes blockchain novel.
