Hash: SHA512

FWIW, the 6 confirmations figure came from a modest estimate of a miner
with 10% of the hash rate, such that there is < 0.1% probability of the
transaction being undone.

I wonder at times if this figure should fluctuate with the hashrate of
the largest player. Presently, AntMiner has 20% of the hashrate,
requiring 11 blocks to give you the same certainty. And previously when
GHash.io had 45%, the number of blocks to wait would be 340 - over two days!

With this in mind, I would be wary about publishing these numbers as
they are prone to change.
