I just watched What Bitcoin Did with nostr:npub1s5yq6wadwrxde4lhfs56gn64hwzuhnfa6r9mj476r5s4hkunzgzqrs6q7z. Preston was explaining Bitcoin backed bonds. The key management is what I dont get. If I by a Bitcoin backed bond and I want to trade it. How are the keys being traded along with the bond on an OTC desk. Lets say I work at a major insurance company and I manage our 50 billion to pay claims. Would the custodian or broker dealer just keep the keys and push them along with the paper? Would I have to burn my keys somehow when I get USD for the Bitcoin backed bond that I just sold? How would that work?
