Distributed trust systems ought to work because we love the idea, but there is always the chance we shall find that anonymity is not such a good thing for trust.

I see no particular reason why bitcoin addresses should remain anonymous in the future, making the impact of this power less, but still a fix to the protocol or a lot more miners will be preferable.

I would love to know if this is because the GHash pool has grown (through presumably investing 2012/13-bitcoin profits into hardware) or if it's because others stopped hashing.
