Types

type AncestorTree 

type AncestorTree interface {
	Add(blkID ids.ID, parentID ids.ID)
	Has(blkID ids.ID) bool
	GetRoot(blkID ids.ID) ids.ID
	Remove(blkID ids.ID)
	RemoveSubtree(blkID ids.ID)
	Len() int
}

func NewAncestorTree 

func NewAncestorTree() AncestorTree

type Config 

type Config struct {
	common.AllGetsServer

	Ctx        *snow.ConsensusContext
	VM         block.ChainVM
	Sender     common.Sender
	Validators validators.Set
	Params     snowball.Parameters
	Consensus  snowman.Consensus
}

Config wraps all the parameters needed for a snowman engine

type Engine 

type Engine interface {
	common.Engine
	block.Getter
}

Engine describes the events that can occur to a Snowman instance.

The engine is used to fetch, order, and decide on the fate of blocks. This engine runs the leaderless version of the Snowman consensus protocol. Therefore, the liveness of this protocol tolerant to O(sqrt(n)) Byzantine Nodes where n is the number of nodes in the network. Therefore, this protocol should only be run in a Crash Fault Tolerant environment, or in an environment where lose of liveness and manual intervention is tolerable.
