* Replace the old blockSubsidy parameters with the new ones. * Return subsidyGenesisReward if blockHash is the genesis hash. * Traverse a block's past for the subsidy calculation. * Partially implement SubsidyStore. * Refer to SubsidyStore from CoinbaseManager. * Wrap calcBlockSubsidy in getBlockSubsidy, which first checks the database. * Fix finalityStore not calling GenerateShardingID. * Implement calculateAveragePastSubsidy. * Implement calculateMergeSetSubsidySum. * Implement calculateSubsidyRandomVariable. * Implement calcBlockSubsidy. * Add a TODO about floats. * Update the calcBlockSubsidy TODO. * Use binary.LittleEndian in calculateSubsidyRandomVariable. * Fix bad range in calculateSubsidyRandomVariable. * Replace float64 with big.Rat everywhere except for subsidyRandomVariable. * Fix a nil dereference. * Use a random walk to approximate the normal distribution. * In order to avoid unsupported fractional results from powInt64, flip the numerator and the denominator manually. * Set standardDeviation to 0.25, MaxSompi to 10_000_000_000 * SompiPerKaspa and defaultSubsidyGenesisReward to 1_000. * Set the standard deviation to 0.2. * Use a binomial distribution instead of trying to estimate the normal distribution. * Change some values around. * Clamp the block subsidy. * Remove the fake duplicate constants in the util package. * Reduce MaxSompi to only 100m Kaspa to avoid hitting the uint64 ceiling. * Lower MaxSompi further to avoid new and exciting ways for the uint64 ceiling to be hit. * Remove debug logs. * Fix a couple of failing tests. * Fix TestBlockWindow. * Fix limitTransactionCount sometimes crashing on index-out-of-bounds. * In TrustedDataDataDAABlock, replace BlockHeader with DomainBlock * In calculateAveragePastSubsidy, use blockWindow instead of doing a BFS manually. * Remove the reference to DAGTopologyManager in coinbaseManager. * Add subsidy to the coinbase payload. * Get rid of the subsidy store and extract subsidies out of coinbase transactions. * Keep a blockWindow amount of blocks under the virtual for IBD purposes. * Manually remove the virtual genesis from the merge set. * Fix simnet genesis. * Fix TestPruning. * Fix TestCheckBlockIsNotPruned. * Fix TestBlockWindow. * Fix TestCalculateSignatureHashSchnorr. * Fix TestCalculateSignatureHashECDSA. * Fix serializing the wrong value into the coinbase payload. * Rename coinbaseOutputForBlueBlock to coinbaseOutputAndSubsidyForBlueBlock. * Add a TODO about optimizing trusted data DAA window blocks. * Expand on a comment in TestCheckBlockIsNotPruned. * In calcBlockSubsidy, divide the big.Int numerator by the big.Int denominator instead of converting to float64. * Clarify a comment. * Rename SubsidyMinGenesisReward to MinSubsidy. * Properly handle trusted data blocks in calculateMergeSetSubsidySum. * Use the first two bytes of the selected parent's hash for randomness instead of math/rand. * Restore maxSompi to what it used to be. * Fix TestPruning. * Fix TestAmountCreation. * Fix TestBlockWindow. * Fix TestAmountUnitConversions. * Increase the timeout in many-tips to 30 minutes. * Check coinbase subsidy for every block * Re-rename functions * Use shift instead of powInt64 to determine subsidyRandom Co-authored-by: Ori Newman <orinewman1@gmail.com>
