The epochs topic streams consensus results: the total order of blocks, as expressed by a sequence of epochs. The returned series of epoch numbers is monotonically increasing with an increment of one. If you see the same epoch twice, this suggests a pivot chain reorg has happened (this might happen for recent epochs). For each epoch, the last hash in epochHashesOrdered is the hash of the pivot block.

The logs topic streams all logs matching a certain filter, in order. In case of a pivot chain reorg (which might affect recent logs), a special revert message is sent. All logs received previously that belong to epochs larger than the one in this message should be considered invalid.
