In this series I paired up with Denis, a cybersecurity veteran and research engineer with nearly 2 decades of experience, to help his team at Protocol Labs (The creators of Filecoin) audit a Solidity implementation of their hierarchical consensus model.

We uncovered many bugs throughout the process, all findings from the sessions have been documented here: https://github.com/consensus-shipyard...

Additional documentation about the ipc-actors and hierarchical consensus can be found here:
