Functions

func BlockSubsidy

func BlockSubsidy(height uint64) uint64

BlockSubsidy calculate the coinbase rewards on given block height

Types

type BasicConfig

type BasicConfig struct {
	// gas config
	MaxBlockGas      uint64 // the max used gas for all transactions of a block
	MaxGasAmount     int64  // the max gas for a transaction
	DefaultGasCredit int64  // the max default credit gas for a transaction with non-BTM asset
	VMGasRate        int64  // the gas rate for VM
	StorageGasRate   int64  // the gas rate for storage

	// utxo config
	VotePendingBlockNumber     uint64 // the valid block interval for vote utxo after the vote transaction is confirmed
	CoinbasePendingBlockNumber uint64 // the valid block interval for coinbase utxo after the coinbase transaction is confirmed
	CoinbaseArbitrarySizeLimit int    // the max size for coinbase arbitrary
}

BasicConfig indicate the basic config

type Checkpoint

type Checkpoint struct {
	Height uint64
	Hash   bc.Hash
}

Checkpoint identifies a known good point in the block chain. Using checkpoints allows a few optimizations for old blocks during initial download and also prevents forks from old blocks.

type DPOSConfig

type DPOSConfig struct {
	NumOfConsensusNode      int64  // the number of consensus node
	BlockNumEachNode        uint64 // the number of generated continuous blocks for each node
	RoundVoteBlockNums      uint64 // the block interval which count the vote result in a round
	MinConsensusNodeVoteNum uint64 // the min BTM amount for becoming consensus node(the unit is neu)
	MinVoteOutputAmount     uint64 // the min BTM amount for voting output in a transaction(the unit is neu)
	BlockTimeInterval       uint64 // the block time interval for producting a block
	MaxTimeOffsetMs         uint64 // the max number of seconds a block time is allowed to be ahead of the current time
}

DPOSConfig indicate the dpos consensus config

func VaporDPOSConfig

func VaporDPOSConfig() DPOSConfig

VaporDPOSConfig return the dpos consensus config

type Params

type Params struct {
	// Name defines a human-readable identifier for the network.
	Name string

	// Bech32HRPSegwit defines the prefix of address for the network
	Bech32HRPSegwit string

	// DefaultPort defines the default peer-to-peer port for the network.
	DefaultPort string

	// BasicConfig defines the gas and utxo relatived paramters.
	BasicConfig

	// DPOSConfig defines the dpos consensus paramters.
	DPOSConfig

	// DNSSeeds defines a list of DNS seeds for the network that are used
	// as one method to discover peers.
	DNSSeeds []string

	// Checkpoints defines the checkpoint blocks
	Checkpoints []Checkpoint

	// ProducerSubsidys defines the producer subsidy by block height
	ProducerSubsidys []ProducerSubsidy
}

Params store the config for different network

func BytomMainNetParams

func BytomMainNetParams(vaporParam *Params) *Params

BytomMainNetParams is the config for bytom mainnet

type ProducerSubsidy

type ProducerSubsidy struct {
	BeginBlock uint64
	EndBlock   uint64
	Subsidy    uint64
}

ProducerSubsidy is a subsidy to the producer of the generated block

type ServiceFlag

type ServiceFlag uint64

ServiceFlag use uint64 to indicate what kind of server this node can provide. one uint64 can represent 64 type of service flag

const (
	// SFFullNode is a flag used to indicate a peer is a full node.
	SFFullNode ServiceFlag = 1 << iota
	// SFFastSync indicate peer support header first mode
	SFFastSync
	// SFSPV indicate peer support spv mode
	SFSPV
	// DefaultServices is the server that this node support
	DefaultServices = SFFullNode | SFFastSync | SFSPV
)

func (ServiceFlag) IsEnable

func (f ServiceFlag) IsEnable(checkFlag ServiceFlag) bool

IsEnable check does the flag support the input flag function
