We need to do the following
(1) Something to compute the seedHash, check the header that it is right
(2) Something that does “quick verification” to prevent spam, using the mixDigest
(3) Something that does verification, possibly generating the cache on the fly from the seedHash
(4) Something that mines, using the cache rather than the full dataset.
