Genesis block for known chains, mine dev chains (#269)
Renamed mining parameter mode to chain type, with existing types
of CI testing, user testing, testnet1 or mainnet. The public
chains (testnet1 and mainnet) come with their fully pre-defined
genesis block.

Still need to set the nonce and cycle for testnet1 genesis.

36bcd3cc39 Integrate sum trees with the rest of the system (#116)
* 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

97b7421ce0 Mining test debug output, fixes to diff. adjustment and start of POW documentation (#69)
* Beginning to add a POW description, and some minor changes to mining testing, addition of further debug information to mining output.
* Many additions to create first draft of POW documentation
* Fixes to difficult adjustments by adding a MINIMUM_DIFFICULTY consensus value. Otherwise never adjusted above 1 due to flooring.

Apply new difficulty algo, remove configurable cuckoo size
Integrate the new difficulty calculation into the block chain
validation, the miner and tests. As the difficulty calculation
doesn't use varying Cuckoo sizes anymore and we narrowed down
reasonable final Cuckoo Cycle parameters, removed all Cuckoo
Cycle sizes from block headers.

Formalized easier Cuckoo Cycle sizes for testing (and possibly
testnet) by introducing a test mode in configuration. Updated
all tests.

Add features bitmask to Block, Output, Kernel; coinbase validation
Block, Output and Kernel now have bitmasks to hold supported
features and eventually versioning. Will make adding features and
updates easier and open the possibility of soft forks.

First added feature for Output and Kernel is the marking of coinbase
related ones. Allows the validation of the coinbase part of a block.

Cleanup of Transaction and Block data structures
Some renaming and cleanup of the Input, Output, Transaction and
Block structs. The main change is the removal of all the overt
structures which are now replaced by a specialized module to
build transactions easily. More specifically:

* Rename the TxProof to TxKernel in Block to reflect the current
naming consensus in MimbleWimble.
* Change Input and Output to be plain structs instead of enums
making their manipulation a lot easier. The building of
transactions is now handled by the build module.
* Input now directly includes the commitment of the Output it's
spending instead of going through an intermediate hash.
* The new build module encapsulates all the transaction building
logic, making it very straightforward by chaining combinators.
* Moves some tests to the core mod.rs as they required being able
to build a transaction to test it.

Block headers maintain total difficulty up to previous. Changed all references of target to difficulty to stay consistent. Ported retargeting algo to use difficulty as well. 2016-12-26 15:39:31 -08:00

2e6d3d9fdb Safer serialization of base types (#18)
* use MESSAGE_SIZE constant instead of 32
* use Hashed trait in genesis
* safer serialization of Hash
* Hashed of [u8] should send only data to hash function, not length + data
* Safer serialization of Proof
* Safer serialization of Commitment
* Safer serialization of RangeProof
* introduce read_limited_vec instead of potential panic in conversion

Block now uses the new Target type. Consensus next_target calculation adjusting every block based on deviation and increasing Cuckoo size gradually. Block time of a minute until we learn more from mining ecosystem, so enough PoW attempts can be made even on CPUs. 2016-11-15 14:41:16 -08:00
