Functions

func DCP0010Active

func DCP0010Active(ctx context.Context, height int32, params *chaincfg.Params,
	querier Querier) (bool, error)

DCP0010Active returns whether the consensus rules for the next block with the current chain tip height requires the subsidy split as specified in DCP0010. DCP0010 is always active on simnet, and requires the RPC syncer to detect activation on mainnet and testnet3.

func DCP0012Active

func DCP0012Active(ctx context.Context, height int32, params *chaincfg.Params,
	querier Querier) (bool, error)

DCP0012Active returns whether the consensus rules for the next block with the current chain tip height requires the version 2 subsidy split as specified in DCP0012. DCP0012 requires the RPC syncer to detect activation on mainnet, testnet3 and simnet.

Types

type HardcodedDeployment

type HardcodedDeployment struct {
	MainNetActivationHeight  int32
	TestNet2ActivationHeight int32
	TestNet3ActivationHeight int32
	SimNetActivationHeight   int32
}

HardcodedDeployment specifies hardcoded block heights that a deployment activates at. If the value is negative, the deployment is either inactive or can't be determined due to the uniqueness properties of the network.

Since these are hardcoded deployments, and cannot support every possible network, conditional logic should only be applied when a deployment is active, not when it is inactive.

func (*HardcodedDeployment) Active

func (d *HardcodedDeployment) Active(height int32, net wire.CurrencyNet) bool

Active returns whether the hardcoded deployment is active at height on the network specified by params. Active always returns false for unrecognized networks.

type Querier

type Querier interface {
	// Deployments should return information about existing agendas,
	// including their deployment status.
	Deployments(context.Context) (map[string]dcrdtypes.AgendaInfo, error)
}

Querier defines the interface for a chain backend that can (trustfully) query for agenda deployment information.
