I wish I had handled the "proof of liabilities" question better.
I knew about proofimint, which was one of the Fedi hackathon winners from last year, and the general direction of counting minted/burned ecash. But I couldn't remember the name of proofimint, and in general didn't want to say something incorrect about the technical limitations of how Chaumian mints evidence liabilities.
This primer by Calle goes into good detail on Chaumian proof-of-liabilities:

👏🏽👏🏽👏🏽 gold to bitcoin is a leap from tangible to intangible value, derived from proof of work. Alchemy at an elevated perspective. As adoption grows it will also produce a psychological shift in society from materialism to intangible values so as these projects grow and with your well articulated research and reporting so too will the energy flow. Compliments to you and everyone for 2024. 
That was a good magic trick!
