Yeastplume 42376e68bc Cuckoo-miner better merged into Grin (#80)
* Adding cuckoo-miner into grin as a proper dependency now
* Defaulting to using cuckoo-miner
* Updates to tests to use cuckoo_miner by default, (using cuckoo16)

Yeastplume 12480e7310 Changes to allow for testing and playing with cuckoo-miner integration (#76)
* Refactoring to allow for different miner implementations. Added conditional support for compiling and loading the cuckoo-miner plugin project.
* Small changes to experimentally integrate with cuckoo-miner and compatibility with latest version of cuckoo-miner.
* Turning off inclusion of cuckoo_miner by default
* Disabling simulate_parallel_mining test for now

Yeastplume 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.

Ignotus Peverell 75f19ecfab Fix difficulty tests, forgot to rename method 2017-06-20 10:21:31 -07:00
Ignotus Peverell e8a6b61100 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.

Ignotus Peverell 45b134ab30 PoW only ever needs the block header, full block unnecessary. 2017-02-07 13:48:11 -08:00
Ignotus Peverell dda223f25b Chain logic to support multiple forks, select the most worked fork as the head. Significantly simplified from the original direction as it doesn't seem that explicitly materializing forks is necessary. Simple total difficulty accounting in block headers helping a lot there. 2017-01-09 15:16:44 -08:00
Ignotus Peverell 85e3255ee4 Removed need for a PowHeader. Directly checking serialization mode in block header serialization instead. 2017-01-09 12:07:38 -08:00
Ignotus Peverell ce23dda6cb 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
Ignotus Peverell c1340223de Minor API change to PoW verify, to use the size provided by the block header by default. 2016-12-20 17:32:19 -08:00
Ignotus Peverell 11b8a6222a Any size pow accesible to tests. 2016-11-29 18:46:28 -08:00
Ignotus Peverell 9795d9e452 Miner facility, using the current chain state to build on top of. 2016-11-27 12:31:15 -08:00
Ignotus Peverell ca26f0c3f7 Block header needs its own deserialization. Fixed pow verify to use the block target. 2016-11-16 14:08:46 -08:00
Ignotus Peverell 3c5e2b2958 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
Ignotus Peverell baeae7d1a5 Merged master. 2016-11-10 15:54:47 -08:00

Ignotus Peverell 6e2a232ca3 Cleaned up total fees from block header. Unnecessary now. 2016-11-09 13:25:40 -08:00

Ignotus Peverell b1762cb5f4 p2p module getting close to first integration test allowing 2 peers to connect. Fleshed out handshake and protocol use. Fixed most errors, just need to make the borrow checker happy. 2016-10-25 22:06:13 -07:00
