  4. def approximateTimestamp: CantonTimestamp

    The approximate timestamp

    The approximate timestamp

    This is either the last observed sequencer timestamp OR the effective timestamp after we observed the time difference of (effective - sequencer = epsilon) to elapse

    Returns a snapshot of the current member topology for the given domain

    Returns a snapshot of the current member topology for the given domain

    The future will wait for the data if the data is not there yet.

  8. def awaitTimestamp(timestamp: CantonTimestamp, waitForEffectiveTime: Boolean)(implicit traceContext: TraceContext): Option[Future[Unit]]

    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.

  11. def currentSnapshotApproximation(implicit traceContext: TraceContext): DomainSnapshotSyncCryptoApi

    Our current snapshot approximation

    Our current snapshot approximation

    As topology transactions are future dated (to prevent sequential bottlenecks), we do have to "guess" the current state, as time is defined by the sequencer after we've sent the transaction. Therefore, this function will return the best snapshot approximation known.

  17. def headSnapshot(implicit traceContext: TraceContext): DomainSnapshotSyncCryptoApi

    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.

    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
