TestNetParams is the config for test-net

Functions

func InitActiveNetParams

func InitActiveNetParams(chainID string) error

InitActiveNetParams load the config by chain ID

func IsBech32SegwitPrefix

func IsBech32SegwitPrefix(prefix string, params *Params) bool

IsBech32SegwitPrefix returns whether the prefix is a known prefix for segwit addresses on any default or registered network. This is used when decoding an address string into a specific address type.

func VotePendingBlockNums

func VotePendingBlockNums(height uint64) uint64

Types

type CasperConfig

type CasperConfig struct {
	// BlockTimeInterval, milliseconds, the block time interval for producing a block
	BlockTimeInterval uint64

	// MaxTimeOffsetMs represent the max number of seconds a block time is allowed to be ahead of the current time
	MaxTimeOffsetMs uint64

	// BlocksOfEpoch represent the block num in one epoch
	BlocksOfEpoch uint64

	// MinValidatorVoteNum is the minimum vote number of become validator
	MinValidatorVoteNum uint64

	// VotePendingBlockNumber is the locked block number of vote utxo
	VotePendingBlockNums []VotePendingBlockNum

	FederationXpubs []chainkd.XPub
}

type Params

type Params struct {
	// Name defines a human-readable identifier for the network.
	Name            string
	Bech32HRPSegwit string
	// DefaultPort defines the default peer-to-peer port for the network.
	DefaultPort string

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

	// CasperConfig defines the casper consensus parameters
	CasperConfig
}

Params store the config for different network

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

type VotePendingBlockNum

type VotePendingBlockNum struct {
