Logbook

This page records a log of the team’s work, thinking, discussions, pains, joys, events, and experiences that happen on a daily basis. It’s supposed to be a kind of Stream of consciousness that can later be searched, analyzed, reviewed in more formal retrospectives.

Rules:

Log days in reverse chronological order, recent first
When the stream is getting too big, such that github refuses to render do the following:
- extract biggest logical section (half-year or quarter) out of this into a correspondingly named Logbook-Year-Hn.md or Logbook-Year-Qn.md page
- update links on top of this page to make it easier to navigate try to fix all links in the wiki at least
- notify the team
Move (and link) recurring sections to relevant dedicated pages.

We have noticed that the testing-preview network was not producing any certificate since the beginning of the epoch 1039. After investigation, we have found out that a SPO with 23M ADA (90% of the stake on the network) had briefly joined the network for few epochs and stopped signing since epoch 1039. This means that the quorum can't be reached with the protocol parameters we run on this network. We will have to regenesis the network at epoch 1090 so that it resumes creating certificates at epoch 1091
We have also kept reviewing the SNARK experimentation by the innovation team for the Mithril certificates
Finally, we have made sure that the KES keys of the test SPOs we run did not need to have their KES keys rotated
