Types ¶
type BlockTimestamp ¶
type BlockTimestamp struct {
// contains filtered or unexported fields
}
BlockTimestamp is a helper structure that performs building and validation of valid timestamp for blocks that are generated by block builder and checked by hotstuff event loop. Let τ be the time stamp of the parent block and t be the current clock time of the proposer that is building the child block An honest proposer sets the Timestamp of its proposal according to the following rule: if t is within the interval [τ + minInterval, τ + maxInterval], then the proposer sets Timestamp := t otherwise, the proposer chooses the time stamp from the interval that is closest to its current time t, i.e. if t < τ + minInterval, the proposer sets Timestamp := τ + minInterval if τ + maxInterval < t, the proposer sets Timestamp := τ + maxInterval
func NewBlockTimer ¶
func NewBlockTimer(minInterval, maxInterval time.Duration) (*BlockTimestamp, error)
NewBlockTimer creates new block timer with specific intervals and time.Now as generator
func (BlockTimestamp) Build ¶
func (b BlockTimestamp) Build(parentTimestamp time.Time) time.Time
Build generates a timestamp based on definition of valid timestamp.
func (BlockTimestamp) Validate ¶
func (b BlockTimestamp) Validate(parentTimestamp, currentTimestamp time.Time) error
Validate accepts parent and current timestamps and checks if current timestamp satisfies definition of valid timestamp. Timestamp is valid if: Timestamp ∈ [τ + minInterval, τ + maxInterval] Returns:
- model.ErrInvalidBlockTimestamp - timestamp is invalid
- nil - success
type NoopBlockTimer ¶
type NoopBlockTimer struct{}
NoopBlockTimer implements an always valid behavior for BlockTimestamp interface. Can be used by nodes that don't perform validation of block timestamps.
func NewNoopBlockTimer ¶
func NewNoopBlockTimer() *NoopBlockTimer
