Functions

func GenerateClusterRootQC

func GenerateClusterRootQC(signers []bootstrap.NodeInfo, allCommitteeMembers flow.IdentityList, clusterBlock *cluster.Block) (*flow.QuorumCertificate, error)

GenerateClusterRootQC creates votes and generates a QC based on participant data

func GenerateExecutionState

func GenerateExecutionState(
	dbDir string,
	accountKey flow.AccountPublicKey,
	chain flow.Chain,
	bootstrapOptions ...fvm.BootstrapProcedureOption,
) (flow.StateCommitment, error)

func GenerateRootBlock

func GenerateRootBlock(chainID flow.ChainID, parentID flow.Identifier, height uint64, timestamp time.Time) *flow.Block

func GenerateRootBlockVotes

func GenerateRootBlockVotes(block *flow.Block, participantData *ParticipantData) ([]*model.Vote, error)

GenerateRootBlockVotes generates votes for root block based on participantData

func GenerateRootClusterBlocks

func GenerateRootClusterBlocks(epoch uint64, clusters flow.ClusterList) []*cluster.Block

func GenerateRootQC

func GenerateRootQC(block *flow.Block, votes []*model.Vote, participantData *ParticipantData, identities flow.IdentityList) (
	*flow.QuorumCertificate,
	[]error,
	error,
)

GenerateRootQC generates QC for root block, caller needs to provide votes for root QC and participantData to build the QC. NOTE: at the moment, we require private keys for one node because we we re-using the full business logic, which assumes that only consensus participants construct QCs, which also have produce votes.

TODO: modularize QC construction code (and code to verify QC) to be instantiated without needing private keys. It returns (qc, nil, nil) if a QC can be constructed with enough votes, and there is no invalid votes It returns (qc, invalidVotes, nil) if there are some invalid votes, but a QC can still be constructed It returns (nil, invalidVotes, err) if no qc can be constructed with not enough votes or running any any exception

func GenerateRootResult

func GenerateRootResult(
	block *flow.Block,
	commit flow.StateCommitment,
	epochSetup *flow.EpochSetup,
	epochCommit *flow.EpochCommit,
) *flow.ExecutionResult

func GenerateRootSeal

func GenerateRootSeal(result *flow.ExecutionResult) (*flow.Seal, error)

Types

type Participant

type Participant struct {
	bootstrap.NodeInfo
	RandomBeaconPrivKey crypto.PrivateKey
}

type ParticipantData

type ParticipantData struct {
	Participants []Participant
	Lookup       map[flow.Identifier]flow.DKGParticipant
	GroupKey     crypto.PublicKey
}

func GenerateQCParticipantData

func GenerateQCParticipantData(allNodes, internalNodes []bootstrap.NodeInfo, dkgData dkg.DKGData) (*ParticipantData, error)

GenerateQCParticipantData generates QC participant data used to create the random beacon and staking signatures on the QC.

allNodes must be in the same order that was used when running the DKG.

func (*ParticipantData) Identities

func (pd *ParticipantData) Identities() flow.IdentityList
