Struct Chain

protocol/protocol.go:113–127

Chain provides a complete, minimal blockchain database. It delegates the underlying storage to other objects, and uses validation logic from package validation to decide what objects can be safely stored.

// validation logic from package validation to decide what
// objects can be safely stored.
type Chain struct {
	InitialBlockHash bc.Hash
	bb               *BlockBuilder

	state struct {
		cond     sync.Cond // protects height, block, snapshot
		height   uint64
		snapshot *state.Snapshot // current only if leader
	}
	store Store

	lastQueuedSnapshotHeight uint64 // atomic access only
	blocksPerSnapshot        uint64
	pendingSnapshots         chan *state.Snapshot
}

// NewChain returns a new Chain using store as the underlying storage.
