Bitcoin Q&A: SegWit and transaction malleability

What is transaction malleability? Can transaction IDs be changed? How does Segregated Witness make the Lightning Network easier to run? When will we have multi-party channel funding and channel balancing with BOLT 1.1.? Are SegWit transactions seen by old nodes as 'anyone can spend'? Is SegWit enough to improve scalability for mass adoption? Do you think we will get more privacy in the Bitcoin protocol before ossification sets in?

These questions are from the February monthly subscriber session and the fifth session of MOOC 11, which took place on February 23rd and March 1st 2019, respectively.
