Types

type InteropBackend

type InteropBackend interface {
	UnsafeView(ctx context.Context, chainID types.ChainID, unsafe types.ReferenceView) (types.ReferenceView, error)
	SafeView(ctx context.Context, chainID types.ChainID, safe types.ReferenceView) (types.ReferenceView, error)
	Finalized(ctx context.Context, chainID types.ChainID) (eth.BlockID, error)

	CrossDerivedFrom(ctx context.Context, chainID types.ChainID, derived eth.BlockID) (eth.L1BlockRef, error)

	UpdateLocalUnsafe(ctx context.Context, chainID types.ChainID, head eth.BlockRef) error
	UpdateLocalSafe(ctx context.Context, chainID types.ChainID, derivedFrom eth.L1BlockRef, lastDerived eth.BlockRef) error
	UpdateFinalizedL1(ctx context.Context, chainID types.ChainID, finalized eth.L1BlockRef) error
}

type InteropDeriver

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

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

func (*InteropDeriver) AttachEmitter

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

func (*InteropDeriver) OnEvent

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

type L2Source

type L2Source interface {
	L2BlockRefByNumber(context.Context, uint64) (eth.L2BlockRef, error)
	L2BlockRefByHash(ctx context.Context, l2Hash common.Hash) (eth.L2BlockRef, error)
}
