Summary

Executive Summary This report presents the results of our second engagement with Skale to review Skale Manager code that manages the nodes and schain grouping and rotations. The delegation, validator and token functions of the SKALE Manager system were previously audited by ConsenSys Diligence. The review was conducted over two weeks, from Oct 19, 2020 to Nov 6, 2020 by Sergii Kravchenko and Shayan Eskandari. During the first week, we got a walk through on the code, reviewed the overall design and started the cryptographic review in parallel.
