interop

type InteropBackend ¶ added in v1.9.3

type InteropBackend interface {
	CheckBlock(ctx context.Context,
		chainID types.ChainID, blockHash common.Hash, blockNumber uint64) (types.SafetyLevel, error)
}

type InteropDeriver ¶ added in v1.9.3

type InteropDeriver struct {
	// contains filtered or unexported fields
}

InteropDeriver watches for update events (either real changes to block safety, or updates published upon request), checks if there is some local data to cross-verify, and then checks with the interop-backend, to try to promote to cross-verified safety.

func NewInteropDeriver(log log.Logger, cfg *rollup.Config,
	driverCtx context.Context, backend InteropBackend, l2 L2Source) *InteropDeriver

func (d *InteropDeriver) AttachEmitter(em event.Emitter)

func (d *InteropDeriver) OnEvent(ev event.Event) bool

type L2Source ¶

type L2Source interface {
	L2BlockRefByNumber(context.Context, uint64) (eth.L2BlockRef, error)
}
