Constants

const (
	// DeploymentTestDummy defines the rule change deployment ID for testing
	// purposes.
	DeploymentTestDummy = iota

	// DeploymentCSV defines the rule change deployment ID for the CSV
	// soft-fork package. The CSV package includes the deployment of BIPS
	// 68, 112, and 113.
	DeploymentCSV

	// DeploymentSegwit defines the rule change deployment ID for the
	// Segregated Witness (segwit) soft-fork package. The segwit package
	// includes the deployment of BIPS 141, 142, 144, 145, 147 and 173.
	DeploymentSegwit

	// DefinedDeployments is the number of currently defined deployments.
	DefinedDeployments
)

Constants that define the deployment offset in the deployments field of the parameters for each deployment. This is useful to be able to get the details of a specific deployment by name.

LtcTestNet4Params defines the network parameters for the test Litecoin network (version 4). Not to be confused with the regression test network, this network is sometimes simply called "testnet".

Types

type ConsensusDeployment

type ConsensusDeployment struct {
	// BitNumber defines the specific bit number within the block version
	// this particular soft-fork deployment refers to.
	BitNumber uint8

	// StartTime is the median block time after which voting on the
	// deployment starts.
	StartTime uint64

	// ExpireTime is the median block time after which the attempted
	// deployment expires.
	ExpireTime uint64
}

ConsensusDeployment defines details related to a specific consensus rule change that is voted in. This is part of BIP0009.
