Jack Grigg aea79ec053 Adjust test to avoid spurious failures 
Previously, if the two random numbers happened to be equal, the block time
would not be updated, and subsequent checks would fail.

Jack Grigg 333ea3c426 Remove testnet-only difficulty rules 
The min-difficulty blocks are incompatible with difficulty averaging.

Network difficulty is also now defined as the difficulty the network is
currently working to solve, rather than the last non-min-difficulty block
difficulty.

Jack Grigg 00939d09ba Add test comparing GetDifficulty() with GetNetworkDifficulty() 2016-09-01 16:36:18 +12:00
Jack Grigg 695a7a8826 Separate concepts of block difficulty and network difficulty in RPC 
"Block difficulty" is the difficulty listed in a block's header, which in the
testnet can sometimes be min-difficulty (if time-since-last-block is too large).

"Network difficulty" is the difficulty that the network was trying to satisfy
at a particular block height. In mainnet this is always equal to the difficulty
of the solved block for that height, but in testnet the network difficulty is
derived from the last non-min-difficulty block difficulty.

This commit fixes the RPC APIs that are intended to show network difficulty, so
that on testnet they don't sometimes drop to 1.0, confusing users.

Closes #1181

Jack Grigg 38a6e7a74d Set witness cache size equal to coinbase maturity duration 
Both constants have the same implicit assumption: that the blockchain will very
rarely undergo a reorganisation of that size.

The anchor is obtained from the returned witnesses; since all witnesses are to
the same point (the latest blockchain tip), they all have the same root.

Jack Grigg 488e61e852 Undo debugging change from 5be6abbf84 
This was unintentionally committed, and caused Equihash verification of blocks
without parents to be skipped. This only affects the genesis block on the test
network, but also causes the "time verifyequihash" benchmark to incorrectly
appear instantaneous.

Closes #892
 2016-08-16 18:32:56 +12:00
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

- An array of N blocks of ceil(L/8) bytes.

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.

 2016-07-22 14:17:46 +12:00
Jack Grigg e99731b4a4 Reinstate previous testnet adjustment behaviour 
When the difficulty adjustment algorithm was altered, the special testnet
min-difficulty case was maintained, but the difficulty adjustment for the
following block then adjusted from min-difficulty instead of from the last
non-min-difficulty block. This caused the difficulty on the testnet to sawtooth
instead of stabilising. The intended behaviour is restored here.

Jack Grigg 8e165d57d9 Randomise the nonce in the block header 
The top and bottom 16 bits of the nonce are left clear for local use as thread

miner than is currently exposed.

The cleared bits should not be considered a consensus rule, as miners are free
to set all bits of the nonce however they wish.
