Types

type BlockGenerator

type BlockGenerator struct {
	// contains filtered or unexported fields
}

func NewChainBlockGenerator

func NewChainBlockGenerator(stateInfo StateProvider) *BlockGenerator

func (*BlockGenerator) AcceptBlock

func (c *BlockGenerator) AcceptBlock(wire.BlockHeader) error

func (*BlockGenerator) CalcBlockSubsidy

func (c *BlockGenerator) CalcBlockSubsidy(height int32, header wire.BlockHeader) int64

CalcBlockSubsidy returns the subsidy amount a block at the provided height should have. This is mainly used for determining how much the coinbase for newly generated blocks awards as well as validating the coinbase for blocks has the expected value.

| Year | First Block | Last block | Formula based on block number | First Block reward | Last block reward | |------|-------------|------------|---------------------------------------|--------------------|-------------------| | 1 | 1 | 49152 | `340-10*([(x-1+3*2^10)/(3*2^11])` | 340 | 260 | | 2 | 49153 | 98304 | `260-5*([(x-49153+3*2^10)/(3*2^11])` | 260 | 220 | | 3 | 98305 | 147456 | `220-15*([(x-98305+3*2^10)/(3*2^11])` | 220 | 100 | | 4 | 147457 | 196608 | `100-5*([(x-147157+3*2^10)/(3*2^11])` | 100 | 60 | | 5 | 196609 | 245760 | `60-5*([(x-196609+3*2^10)/(3*2^11])` | 60 | 20 | | 6+ | 245761 | | 20 | 20 | |
