type BatchRequest struct {
	Nonce    uint64
	BlockIDs []flow.Identifier
}

BatchRequest is part of the sychronization protocol and represents an active (pulling) attempt to synchronize with the consensus state of the network. It requests finalized or unfinalized blocks by a list of block IDs.

type BlockProposal 

type BlockProposal struct {
	Block UntrustedBlock
}

BlockProposal is part of the consensus protocol and represents the leader of a consensus round pushing a new proposal to the network.

type BroadcastDKGMessage 

type BroadcastDKGMessage struct {
