Types

type FinalizationConsensus

type FinalizationConsensus struct {
	// contains filtered or unexported fields
}

func (*FinalizationConsensus) ExpectedBlockHeight

func (s *FinalizationConsensus) ExpectedBlockHeight(chainParser chainlib.ChainParser) (expectedBlockHeight int64, numOfProviders int)

returns the expected latest block, does the calculation on finalized entries then extrapolates the ending based on blockDistance

func (*FinalizationConsensus) NewEpoch

func (fc *FinalizationConsensus) NewEpoch(epoch uint64)

func (*FinalizationConsensus) UpdateFinalizedHashes

func (fc *FinalizationConsensus) UpdateFinalizedHashes(blockDistanceForFinalizedData int64, providerAddress string, latestBlock int64, finalizedBlocks map[int64]string, req *pairingtypes.RelaySession, reply *pairingtypes.RelayReply) (finalizationConflict *conflicttypes.FinalizationConflict, err error)

Compare finalized block hashes with previous providers Looks for discrepancy with current epoch providers if no conflicts, insert into consensus and break create new consensus group if no consensus matched check for discrepancy with old epoch checks if there is a consensus mismatch between hashes provided by different providers

type ProviderHashesConsensus

type ProviderHashesConsensus struct {
	FinalizedBlocksHashes map[int64]string
	// contains filtered or unexported fields
}

type RelayRequestCommonData
