This moves several of the chain constants to the Params struct in the chaincfg package which is intended for that purpose. This is mostly a backport of the same modifications made in Decred along with a few additional things cleaned up. The following is an overview of the changes: - Comment all fields in the Params struct definition - Add locals to BlockChain instance for the calculated values based on the provided chain params - Rename the following param fields: - SubsidyHalvingInterval -> SubsidyReductionInterval - ResetMinDifficulty -> ReduceMinDifficulty - Add new Param fields: - CoinbaseMaturity - TargetTimePerBlock - TargetTimespan - BlocksPerRetarget - RetargetAdjustmentFactor - MinDiffReductionTime
