I enjoy thinking about nation state multisig, storing trillions of dollars of value in a safe way by people that are technologically retarded.

Here’s my half-baked concept:

5 of 9. In the United States you’d have these 9 people hold a hardware wallet: President, VP, President’s Chief of Staff, Speaker of the House, Senate Majority Leader, Senate Minority Leader, 3 most senior Supreme Court Justices.

Since these people are prone to losing or bricking their hardware wallets, redundant clones are kept in large clear lock boxes in open public spaces in large cities so the citizens can all see if keys are ever being rotated out.

In a 5 of 9, you’d have to have two branches of government agree to spend, you’d have to have 5 people be compromised to get swept, with redundant devices, losing coins due to incompetence is nearly impossible.

10 BTC would be left on each of the 9 single sig wallets as an incentive for someone to sweep the funds and reveal that they have compromised 1 of the 9 keys and discourage the attacker from going after subsequent keys. The attacker would get to keep the funds as long as they shared how they did it. These security holes would then be patched.

Who’s got better ideas?
