type State

type State interface {
	Get(key string) ([]byte, error)
	Set(key string, value []byte) error
	Delete(key string) error
	Reset(stateDbPath string) (string, error)

	SaveOffset(uint64) error
	LoadOffset() (uint64, error)
	GetOrError(key string) ([]byte, error)
}

State is the node's state (it keeps the offset, the signatures and the Operation pool.
