Functions

func AccountFixture added in v0.23.5

This means execution result where event was emitted is sealed, and the seal is finalized by a valid block. This assumes state is bootstrapped with a root block, as it does NOT produce results for final block of the state Root <- A <- B(result(A(VB))) <- C(seal(B))

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, processing D causes the EpochSetup to become activated.

F contains a seal for block D containing the EpochCommit service event. processing F 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.
