I think the most promising work here is around fork futures. Paul Sztorc (of Bitcoin Hivemind, the original decentralized prediction market, and Drivechains) has a lot to say about how with fork futures, we can let the market tell us how valuable proposals are [0]. We saw this in practice with the numerous S2X futures that were available. They were all predicting that S2X had about 13% chance of winning. This signal can then be used as substantial evidence in meatspace to retract or push forward a proposal. [0] http://www.truthcoin.info/blog/fork-futures/ http://www.truthcoin.info/blog/fork-futures/
