* large updates for mining, fix async mode, will list changes in PR
* reset config and build defaults
* change to difficulty calculations
* tweaking mining params and tests
* tweaking to tests
* including pre-genesis data for difficulty adjustments, adding adjustment scenario tests
* further clarifying next_difficulty function
* moving tests out of consensus.rs
* pow test fix
* changing pre-genesis generation
* experiment with lock_heights on outputs
* playing around with lock_height as part of the switch commitment hash
* cleanup
* include features in the switch commit hash key
* commit
* rebase off master
* commit
* cleanup
* missing docs
* rework coinbase maturity test to build valid tx
* pool and chain tests passing (inputs have switch commitments)
* commit
* cleanup
* check inputs spending coinbase outputs have valid lock_heights
* wip - got it building (tests still failing)
* use zero key for non coinbase switch commit hash
* fees and height wrong order...
* send output lock_height over to wallet via api
* no more header by height index
workaround this for wallet refresh and wallet restore
* refresh heights for unspent wallet outputs where missing
* TODO - might be slow?
* simplify - do not pass around lock_height for non coinbase outputs
* commit
* fix tests after merge
* build input vs coinbase_input
switch commit hash key encodes lock_height
cleanup output by commit index (currently broken...)
* is_unspent and get_unspent cleanup - we have no outputs, only switch_commit_hashes
* separate concept of utxo vs output in the api
utxos come from the sumtrees (and only the sumtrees, limited info)
outputs come from blocks (and we need to look them up via block height)
* cleanup
* better api support for block outputs with range proofs
* basic wallet operations appear to work
restore is not working fully
refresh refreshes heights correctly (at least appears to)
* wallet refresh and wallet restore appear to be working now
* fix core tests
* fix some mine_simple_chain tests
* fixup chain tests
* rework so pool tests pass
* wallet restore now safely habndles duplicate commitments (reused wallet keys)
for coinbase outputs where lock_height is _very_ important
* wip
* validate_coinbase_maturity
got things building
tests are failing
* lite vs full versions of is_unspent
* builds and working locally
zero-conf - what to do here?
* handle zero-conf edge case (use latest block)
* introduce OutputIdentifier, avoid leaking SumCommit everywhere
* fix the bad merge
* pool verifies coinbase maturity via is_matured
this uses sumtree in a consistent way
* cleanup
* add docs, cleanup build warnings
* fix core tests
* fix chain tests
* fix pool tests
* cleanup debug logging that we no longer need
* make out_block optional on an input (only care about it for spending coinbase outputs)
* cleanup
* bump the build
* Make total_difficulty the sum of network difficulty, not whatever the miner happened to mine.
- Only for Testnet2 / Mainnet (hardforks Testnet1)
- update chain::pipe validate_header to validate according to Testnet2 rules for cumulative difference
Fixes#280
* tests that should ignore (network) difficulty
* fn new_block is explained as "utility to create a block without worrying about the key or previous header" so it gets network difficulty := 0 too
* update tx pool tests (going with "minimum" for network difficulty for now)
* add ERR outputs about bannable offences
(#406 should know about these)
* whitespace fix
* mine_simple_chain: Probably DON'T overwrite difficulty (?)
* core/mod tests "reward_empty_block" and "reward_with_tx_block" tests set to use lowest network difficulty possible
* port simple_sync across from testnet1, sync head & improved fork handling
* introduce new sync_head for tracking header chain during sync
* add debug logging in body_sync for state of various heads
* update header_head during sync if header is now the one with most work, pass in sync and head contexts to pipe
* port across sync_head changes from master, put the 1s sleep back in...
* let sync run even if the full 512 headers are all known, give sync a chance to sync against a fork that forked a long time ago
* handle height jumping during a reorg
block validaton should not check for height+1 based on head
no assumptions should be made about height indices
* quick(er) check for previous block in process_block (we cannot check height against ctx head)
* make body_sync a _lot_ faster by finding the forked block more efficiently...
* fix monitoring peers log msg
* fix chain tests
* fix grin tests - we were using the wrong genesis hash (wrong chain type)
* apparently needs setting in both places...
* body -> header -> sync (#414)
* port over body -> header -> sync changes from testnet1
* rename pubkey -> key_id, these are key identifiers, not public keys
* reduce identifier seize to 10 bytes, get rid of fingerprints (identifiers are now small enough to use as-is)
* IDENTIFIER_SIZE const
* add FeeDispute error for when sender and recipient disagre on fee calculation (should never happen)
* does not need to be mut
* cleaned up some warnings
* store wallet output data in hashmap
* cleanup up commented out code
* pass pubkey/identifier and not derivation around to miner etc.
* fix failing tests
* introduce grin_keychain, encapsulate derivation of secret_keys
* core compiles against keychain, tests don't run yet
* core tests are now passing against keychain
* wip - getting wallet working with keychain
* add util and keychain to travis test matrix
* basic test around key derivation
* initial pass at indexing block header hashes by commitments
* check block height matches currently indexed block height
when getting block header for an output commit
* add some test coverage
* document get_block_header_by_output_commit
