Thanks for this. Would it be possible to add a unit test to catch this edge case? |

added in ef242e7, previously we did not test for multiple epoch sizes, this test ensures it for 1,5,10,30, and 60. |

There was a problem hiding this comment.
two things:
wondering if all this repeated code can be avoided by reusing the for i in 0..<rlnMaxEpochGap:. unsure if removing the < may help? afaik the intention here is to add rlnMaxEpochGap + 1 nullifier and see that clearNullifierLog doesn't clean them.
and for completeness, perhaps we should check that clearNullifierLog does clean the log when expected? meaning i keep adding and len()keeps beingrlnMaxEpochGap`?
