I have been trying to find out what inputs go into the block-hash, as far as I can tell:
VRF for the epoch
A private key from the pool operator
I would expect the prior block-hash, and the transaction hashes, anything else?
How then is the hash evaluated, I guess there is no difficulty, but some kind of target for the hash must be set, how does that work?
Links to each element in the code-base would be great too.
