Constants

const DefaultRequiredApprovalsForSealValidation = 0

DefaultRequiredApprovalsForSealValidation is the default number of approvals that should be present and valid for each chunk. Setting this to 0 will disable counting of chunk approvals this can be used temporarily to ease the migration to new chunk based sealing. TODO:

• This value is for the happy path (requires just one approval per chunk).
• Full protocol should be +2/3 of all currently staked verifiers.

Functions

func IntegrityCheck

func IntegrityCheck(receipt *flow.ExecutionReceipt) (flow.StateCommitment, flow.StateCommitment, error)

check the receipt's data integrity by checking its result has both final statecommitment and initial statecommitment

func IsMissingPreviousResultError

func IsMissingPreviousResultError(err error) bool

IsMissingPreviousResultError returns whether the given error is an MissingPreviousResultError error

func NewMissingPreviousResultError

func NewMissingPreviousResultError(previousResultID flow.Identifier) error

func NewReceiptValidator

func NewReceiptValidator(state protocol.State, index storage.Index, results storage.ExecutionResults, verifier module.Verifier) *receiptValidator

func NewSealValidator

func NewSealValidator(state protocol.State, headers storage.Headers, payloads storage.Payloads, seals storage.Seals,
	assigner module.ChunkAssigner, verifier module.Verifier, requiredApprovalsForSealVerification uint, metrics module.ConsensusMetrics) *sealValidator
