| | | | | | | | | | | | | | | * Add test for num of chains changes. * Return error in latticeData.prepareBlock * Compare two positions * Modify chainStatus from height-based to index-based. * Fix consensus to use round variable * Remove sanity check in chainStatus * Fixup: refine sanity check - verify if round switching is required or not by chainTip's config. - make the logic in sanity check more clear - pospone acking relationship checking, they are more expensive to check.
* core: move crypto to core/crypto (#140)Mission Liao2018-09-261-1/+1
| | | | | | | | | - Move key-holder to authenticator Make core.keyHolder public as core.Authenticator, it is not required to make this part an interface. - Make private when there is no need to go public. - Fix data race
* core: run TSIG for first configuration block at startup (#135)Jimmy Hu2018-09-261-0/+28
|
* core: total ordering with chain ID (#100)Mission Liao2018-09-121-1/+1
|
* core: timestamp (#98)Jimmy Hu2018-09-111-12/+11
|
* core: tune total ordering performance (#81)Mission Liao2018-08-301-0/+11
| | | | | - Replace map with slice Compared to slice, accessing to map is slower and the memory usage is inefficient.
* core: Add Consensus to replace core.Blocklattice (#35)Mission Liao2018-08-081-1/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Make Sequencer return slice of blocks. * Fix naming issue The function 'getHeightVecto' would return ackingStatusVector. * Fix comment error. * Add methods to collect info when proposing blocks. * Add test.App * Add test.Gov * Move this type to core.types to avoid cyclic import. * Add core.Consensus * Move getMedianTime, interpoTime to util These functions are not depending on members of core.consensusTimestamp and is required when testing core.Consensus. * Make sure types.Block.Clone would copy critical fields. * Remove core.blocklattice * Define 'infinity' in core/total-ordering This definition is defined in core/blocklattice originally. * Fix a bug when processing the same block twice. * Integrate simulation with core.Consensus core.Consensus is a replacement of core.Blocklattice * Fix the comment to use sigular form. * Move lock mechanism to sub modules. * phi should be 2*fmax+1 * Fixup: should aborting when the validator is added * Fix for new block fields * Fix the bug that the total ordering sequence is wrong.
* Initial implementation of DEXON consensus algorithmWei-Ning Huang2018-07-161-0/+45
