I have guinea pig that I personally trained to mine dogecoin. He did it
pretty well for a while. He is in fact a real live guinea pig. His name
is Lee (not Alice or Bob). With a little work I'm sure Lee could be
trusted to do this as well.

Of course, trusting the trustless way is good too. It's worked quite
well. I sense we are just seeing the tip of the iceberg here.

Hence the "blossoming" remark, but I don't think they've done "nothing."
That's unfair to say. It's just that they're not there yet. In truth,
no-one is really there yet... Zerocash is closest to what I would describe
as "being there." There will be a collective gasp in 2015 when "it"
happens ~ something like a singularity of financial anonymity for
decentralized cryptos.

Agreed. :-)
