    Waits until a snapshot is available

    The snapshot returned by this method should be used for validating transaction and transfer requests (Phase 2 - 7). Use the request timestamp as parameter for this method. Do not use a response or result timestamp, because all validation steps must use the same topology snapshot.

    Returns an optional future which will complete when the timestamp has been observed

    Returns an optional future which will complete when the timestamp has been observed

    If the timestamp is already observed, we return None.

    Note that this function allows to wait for effective time (true) and sequenced time (false). If we wait for effective time, we wait until the topology snapshot for that given point in time is known. As we future date topology transactions (to avoid bottlenecks), this might be before we actually observed a sequencing timestamp.

    Possibly future dated head snapshot

    Possibly future dated head snapshot

    As we future date topology transactions, the head snapshot is our latest knowledge of the topology state, but as it can be still future dated, we need to be careful when actually using it: the state might not yet be active, as the topology transactions are future dated. Therefore, do not act towards the sequencer using this snapshot, but use the currentSnapshotApproximation instead.

  46. def topologyKnownUntilTimestamp: CantonTimestamp

    The most recently observed effective timestamp

    The most recently observed effective timestamp

    The effective timestamp is sequencer_time + epsilon(sequencer_time), where epsilon is given by the topology change delay time, defined using the domain parameters.

    This is the highest timestamp for which we can serve snapshots

    The snapshot returned by this method should be used for validating transaction and transfer requests (Phase 2 - 7). Use the request timestamp as parameter for this method. Do not use a response or result timestamp, because all validation steps must use the same topology snapshot.

  48. def updateHead(effectiveTimestamp: EffectiveTime, approximateTimestamp: ApproximateTime, potentialTopologyChange: Boolean)(implicit traceContext: TraceContext): Unit

    Move the most known timestamp ahead in future based of newly discovered information

    Move the most known timestamp ahead in future based of newly discovered information

    We don't know the most recent timestamp directly. However, we can guess it from two sources: What was the timestamp of the latest topology transaction added? And what was the last processing timestamp. We need to know both such that we can always deliver the latest valid set of topology information, and don't use old snapshots. Therefore, we expose the updateHead function on the public interface for initialisation purposes.

    effectiveTimestamp

    sequencer timestamp + epsilon(sequencer timestamp)

    approximateTimestamp

    our current best guess of what the "best" timestamp is to get a valid current topology snapshot

    potentialTopologyChange

    if true, the time advancement is related to a topology change that might have occurred or become effective
