Types

type Block 

type Block struct {
	BlockMeta
	State BlockState
	Batch *database.Batch
}

type BlockAnchorState added in v1.0.0 

type BlockAnchorState struct {
	ShouldOpenMajorBlock bool
	OpenMajorBlockTime   time.Time
}

BlockAnchorState is used to construc the anchor for the block.

type BlockMeta 

type BlockMeta struct {
	IsLeader   bool
	Index      uint64
	Time       time.Time
	CommitInfo *types.LastCommitInfo
	Evidence   []types.Evidence
}

BlockMeta is metadata about a block.

type BlockState 

type BlockState struct {
	OpenedMajorBlock   bool
	MakeMajorBlock     uint64
	MakeMajorBlockTime time.Time
