ER(X) := ExecutionReceipt for block X S(ER(X)) := Seal for the ExecutionResult contained in ER(X) (seals block X)

A is the latest finalized block. Every block contains a receipt for the previous block and a seal for the receipt contained in the previous block. The only exception is when A is the root block, in which case block B does not contain a receipt for block A, and block C does not contain a seal for block A. This is because the root block is sealed from genesis and we can't insert duplicate seals.

D contains a seal for block B containing the EpochSetup service event. E contains a QC for D, which causes the EpochSetup to become activated.

F contains a seal for block D containing the EpochCommit service event. G contains a QC for F, which causes the EpochCommit to become activated.

To build a sequence of epochs, we call BuildEpoch, then CompleteEpoch, and so on.

Upon building an epoch N (preparing epoch N+1), we store some information about the heights of blocks in the BUILT epoch (epoch N). These can be queried with EpochHeights.

func (*EpochBuilder) CompleteEpoch added in v0.12.0 

func (builder *EpochBuilder) CompleteEpoch() *EpochBuilder

CompleteEpoch caps off the current epoch by building the first block of the next epoch. We must be in the Committed phase to call CompleteEpoch. Once the epoch has been capped off, we can build the next epoch with BuildEpoch.

func (*EpochBuilder) EpochHeights added in v0.15.0 

func (builder *EpochBuilder) EpochHeights(counter uint64) (EpochHeights, bool)

EpochHeights returns heights of each phase within about a built epoch.

func (*EpochBuilder) UsingCommitOpts added in v0.12.0 

func (builder *EpochBuilder) UsingCommitOpts(opts ...func(*flow.EpochCommit)) *EpochBuilder

UsingCommitOpts sets options for the epoch setup event. For options targeting the same field, those added here will take precedence over defaults.

func (*EpochBuilder) UsingSetupOpts added in v0.12.0 

func (builder *EpochBuilder) UsingSetupOpts(opts ...func(*flow.EpochSetup)) *EpochBuilder

UsingSetupOpts sets options for the epoch setup event. For options targeting the same field, those added here will take precedence over defaults.

type EpochHeights added in v0.15.0 

type EpochHeights struct {
	Counter   uint64 // which epoch this is
	Staking   uint64 // first height of staking phase
	Setup     uint64 // first height of setup phase
	Committed uint64 // first height of committed phase
}

EpochHeights is a structure caching the results of building an epoch with EpochBuilder. It contains the first block height for each phase of the epoch.

func (EpochHeights) CommittedRange added in v0.15.0 

func (epoch EpochHeights) CommittedRange() []uint64

CommittedRange returns the range of all heights in the committed phase.

func (EpochHeights) Range added in v0.15.0 

func (epoch EpochHeights) Range() []uint64

Range returns the range of all heights that are in this epoch.

func (EpochHeights) SetupRange added in v0.15.0 

func (epoch EpochHeights) SetupRange() []uint64

SetupRange returns the range of all heights in the setup phase.

func (EpochHeights) StakingRange added in v0.15.0 

func (epoch EpochHeights) StakingRange() []uint64

StakingRange returns the range of all heights in the staking phase.

type FixedStaker added in v0.15.1 

type FixedStaker struct {
	Staked bool
}

func NewFixedStaker added in v0.15.1 

func NewFixedStaker(initial bool) *FixedStaker

func (*FixedStaker) AmIStakedAt added in v0.15.1 

func (f *FixedStaker) AmIStakedAt(_ flow.Identifier) bool
