Bitcoin Q&A: Sidechains and federated consensus

What are sidechains? What is Liquid and what are the use cases of sidechains? What are the differences to the Lightning Network? What do you think about Delegated Byzantine Fault Tolerance? What are issues with these federated models?

These questions are from part of the December, May, and July monthly Patreon sessions, which took place on December 16th 2017, May 26th, and July 26th 2018 respectively. If you want early-access to talks and a chance to participate in the monthly live Q&As with Andreas, become a patron:
