Use a blockchain haha I think this model probably has a lot of possible failure modes, especially when it comes to actual implementation. In the case of two participants, where a fork means the contract is over, that can work. But usually the function of a smart contract is to force agreement on something. Anyway, I'm skeptical, but don't let that stop you. It's an interesting project. If we can indeed figure out a way to have consensus on nostr it would be germane to my key rotation nip, which makes some massive compromises on centralization in order to work: https://github.com/nostr-protocol/nips/pull/2137
