I'd also note the Bitcoin blockchain in particular has pretty substantial
data volume requirements (i.e. Butcoin transactions) consisting of what is
effectively irrelevant information for an identity system.

The usual response I've heard to the argument regarding the high overhead
of layering systems like this on top of the Bitcoin blockchain is that some
trusted caching proxy should do the work of processing the blockchain,
extracting identities and answering requests for them on demand, but at
that point, such a system sounds an awful lot like something like CONIKS
with all of the irrelevant data of Bitcoin transactions.

I feel there's a much simpler approach possible here that doesn't require
coupling to Bitcoin, and I think it looks like CONIKS or CT.
