Hi @Jameson Lopp
Marko from Team @BitBox gave in Lugano a couple of years ago a lecture about the security issues with Multisig.

Have you seen it? Maybe you have already written an in depth article?

The community (especially me 😉 ) is very much interessted on your thoughts. Especially now when everybody is rushing into Multisig.
