* added global slog instance, changed all logging macro formats to include logger instance
* adding configuration to logging, allowing for multiple log outputs
* updates to test, changes to build docs
* rustfmt
* moving logging functions into util crate
* add lock_height to Transaction and TxKernel, sign msg including both fee and lock_height in kernel
* make the order of the fields in tx and kernel more consistent
* rename to kernel_sig_msg
* add test to cover adding timelocked tx to pool, where tx is invalid based on current height of the blockchain
* add tests for adding timelocked txs to blocks (valid and otherwise)
Configuration for a minum accept fee base for the transaction
pool. The base is multipled by a weight computed from the
transaction number of inputs, outputs and kernels. The transaction
fee is required to always be larger than the weight times the
base.
min_fee = base * (-1*input_len + 4*output_len + kernel_len)
The weight is set to never be less than one.
Also added a configurable (and fairly naive for now) max pool
capacity in number of transactions.
* store wallet output data in hashmap
* cleanup up commented out code
* pass pubkey/identifier and not derivation around to miner etc.
* fix failing tests
Update coinbase building and block summation to account for half of
the fees going to the coinbase. Forcing fees to be even as a
consequence. Now that we can't build the coinbase independently
from the block (because fees), had to update the miner to keep the
key derivation so a new derivation isn't made any time a new block
gets worked on.
Minor doc and warning cleanups.
* 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
* Integrate PMMR and its persistent backend with the Chain
* Chain can set tree roots; PMMR backend discard
* Check spent and prune for each input in new block
* Handling of forks by rewinding the state
* More PMMR tests and fixes, mostly around rewind
* Rewrite get_unspent to use the sumtrees, fix remaining compilation issues
* wallet key fingerprint as hex string
* use lowercase hex in util::to_hex for consistency with various crypto libs, add some tests for util::to_hex and util::from_hex
* filter wallet info based on ext_key fingerprint
* cleanup format for fingerprints and output status
* Adding ability to load multiple mining plugins in parallel via cuckoo miner
* updating with newest cuckoo-miner changes
* revert default config value
* update pow document with link to podcast
* workaround the "commitment is not a public key" problem by using to_two_keys() from rust-secp256k1-zkp
* remove secp256k1zkp, update the various Cargo.toml to use rust-secp256k1-zkp from external git repo, update code to not rely on to_pubkey (and use verify_from_commit)
* secp256k1zkp from git
* cleanup secp256k1 dependencies
* gitignore node1 and node2 dirs
* use head_header in add_to_memory_pool
* add COINBASE_MATURITY const to consensus
* add coinbase maturity (wip) validaton rule to validate_block
* add coinbase maturity check to validate_block
* map errors in adapters - specific errors still wip
* reworked so adapter translates chain errors to pool errors (core errors not required)
* add test for spending immature coinbase in memory pool
* wip - add test to cover spending coinbase output in chain.process_block
* added test coverage around process_block - we have a problem with coinbase output commitments
* add a comment on the failing test
* process_block will now fail validation if we attempt to spend coinbase that has not yet matured
(remember to use a new reward_key for every block). test coverage in place to verify this
