* cuck placeholder
* rustfmt
* cuckatoo, early days
* rustfmt
* data structures are in place, siphash key creation is consistent with @tromp
* solver in place, (not yet working)
* cuckatoo test solver working with test nonce
* rustfmt
* update solver to remove adjacency list removals
* verifier functioning
* rustfmt
* Proper error handing in Cuckatoo module, couple of tests
* modify cuckoo/cuckatoo solvers and verifiers to function identically, in advance of trait refactoring
* rustfmt
* refactor PoW context into trait, default to using cuckoo context
* rustfmt
* create macros for integer casting/unwraps
* don't instantiate structs when just verifying, add test validation vector for cuckatoo 29
* rustfmt
* don't init cuckoo structs if just validating
* test fix
* ensure BH hashing for POW is only done within miner/validators
* introduce rewindable_kernel_view
cleanup header in extension
* cleanup and docs/comments
* txhashset does not need to be mutable here
* pull validate_kernel_history out into fn
* block_sums and full kernel sum verification
* rustfmt
* add docs/comments
* docs
* rustfmt
* comment on fact total_kernel_sum is redundant now
* make sure we setup block_sums correctly on a fork
* rustfmt
* replace those asserts with errors
* rustfmt
* Move Proof and Difficulty types to pow module. Difficulty scaling calculation.
* Diffculty scaling and size shift for 2nd PoW
* Backport e7eb26ee
* Test compilation fixes
* Scaling only need to go one way, as @tromp pointed out
* document what we do during pipe::apply_block()
* rustfmt
* wip
* rustfmt
* wip
* additional check_known_store and check_known_mmr checks in process_block
* rustfmt
* cleanup coinbase maturity check in process_block
* consolidate the "check in store" logic
add TODOs around the 50 block OldBlock logic
* rustfmt
* cleanup
* improve: HeaderSync optimization (#1372)
* remove get_locator() optimization, which should be an independent pr for security review
* refactoring: move 'headers_streaming_body()' from Message to Protocol
* move 2 headers utils functions out of Protocol, and remove 'pub'
* support reading variable size of BlockHeader, from Cuckoo30 to Cuckoo36
* fix: use global::min_sizeshift() instead of hardcoded 30, because Cuckoo10 will be used for AutomatedTesting chain
* fix: should use global::proofsize() instead of hardcoded 42 when calculate serialized_size_of_header
* replace another 42 with global::proofsize()
* simplify tx validation and aggregation
we *only* need to account for reward when building a block from txs
* rustfmt
* cleanup and tests passing
* rustfmt
* better comments in with_reward()
* fix wallet tests
* Sort pool tx by fee over weight for mining. Fixes#1105
* Bucketing dependent transactions before weighing. Minor tx weight fixes.
* Limit length of tx chain, cleanup and test fixes
* Cleanup all mining references to a hardcoded tx count
* Small test improvement, cleanup
* Include commitments non-duplicate checks in aggregate
* Remove said check from the pool
* Block building now uses tx aggregation to reduce duplication
* Transaction max weight expressed in terms of block weight
* Cleaned up max block sizes, so everything is in therms of weight
* Cleanup block max constants
* Rename verify_size -> verify_weight
* add new core mmr routine upon which others should be built more efficiently
* tons of pmmr optimizations and simplifications
* fix typo and extend docs
* change initial spaces to tab to fix indentation
