Types

type StateMgr

type StateMgr interface {
	consGR.StateMgr
	// The StateMgr has to find a common ancestor for the prevAO and nextAO, then return
	// the state for Next ao and reject blocks in range (commonAO, prevAO]. The StateMgr
	// can determine relative positions of the corresponding blocks based on their state
	// indexes.
	ChainFetchStateDiff(
		ctx context.Context,
		prevAO, nextAO *isc.AliasOutputWithID,
	) <-chan *sm_inputs.ChainFetchStateDiffResults
	// Invoked by the chain when a set of server (access⁻¹) nodes has changed.
	// These nodes should be used to perform block replication.
	ChainNodesUpdated(serverNodes, accessNodes, committeeNodes []*cryptolib.PublicKey)
	// This is called to save a prelim block, received from other nodes.
	// That should happen on the access nodes to receive the active state faster.
	// This function should save the block (in the WAL) synchronously.
	PreliminaryBlock(block state.Block) error
