Jack Grigg 5be6abbf84 Store the Equihash solution in minimal representation in the block header 
The genesis blocks and miner tests have been regenerated, because changing the
block header serialisation format changes the block hash, and thus validity.

The Equihash solutions have been removed from the bloom test inputs for
simplicity (block validity is not checked there; only a valid serialisation is
necessary).

Jack Grigg 20abe2083c Extend byte array expansion and compression methods with optional padding 2016-08-16 11:02:04 +12:00
Jack Grigg caa0348f04 Update Equihash hash generation to match the Zcash spec 
Changes:

- floor(512/n)*n/8 bytes of BLAKE2b output is split between floor(512/n)
  adjacent indices, instead of using one hash call per index.

- Parameters with n/(k+1) mod 8 != 0 will expand the BLAKE2b output to byte
  boundaries for colliding, instead of using a longer output and clearing bits.

- The genesis blocks have been regenerated.

- The test vectors have been regenerated.

- The Equihash inputs for the cancellation tests were modified to ensure that
  valid solutions were available to exercise the full solver.
 2016-08-16 11:02:04 +12:00
Jack Grigg 881ffbfc87 Add methods for byte array expansion and compression 
These methods convert between:

- A byte array of length NL/8, and
- An array of N blocks of ceil(L/8) bytes.

Jack Grigg eeb4177843 Add Equihash support for n = 200, k = 9 
Closes #1177
 2016-08-06 10:33:14 +12:00
Jack Grigg 036dcbd94a Remove the assumption that n/(k+1) is a multiple of 8. 
This version works, but generates the initial rows in a way that is not what we
want to specify. See #1175 for resolving this.

Jack Grigg d07cf62991 Speed up FullStepRow index comparison by leveraging big-endian byte layout 2016-06-11 16:28:57 +12:00
Jack Grigg ae37d2a4cd Increase Equihash parameters to n = 96, k = 3 (about 430 MiB) 
Includes a tweak to set the fixed-width of the rows based on whether the first
or last round is widest. This is necessary for some parameters, these ones
included.
