Types

type Module

type Module struct {
	Store *storage.MemCachedStore
	// contains filtered or unexported fields
}

Module represents module for local processing of state roots.

func NewModule

func NewModule(bc blockchainer.Blockchainer, log *zap.Logger, s *storage.MemCachedStore) *Module

NewModule returns new instance of stateroot module.

func (*Module) AddMPTBatch

func (s *Module) AddMPTBatch(index uint32, b mpt.Batch) error

AddMPTBatch updates using provided batch.

func (*Module) AddStateRoot

func (s *Module) AddStateRoot(sr *state.MPTRoot) error

AddStateRoot adds validated state root provided by network.

func (*Module) CurrentLocalStateRoot

func (s *Module) CurrentLocalStateRoot() util.Uint256

CurrentLocalStateRoot returns hash of the local state root.

func (*Module) CurrentValidatedHeight

func (s *Module) CurrentValidatedHeight() uint32

CurrentValidatedHeight returns current state root validated height.
