I know Vitalik has talked about using prediction markets as a way for community members to decide on forks.
There are basically 3 proposals that I've seen.
- Hardfork to return all funds to the DAO
- Softfork to freeze the stolen funds (but not return them)
- Do not fork at all and let the thief keep their winnings
There are strong feelings for and against these proposals but I think the vast majority of people are arguing their side because they want Ethereum to continue to thrive.
If there were a prediction market that definitively showed that one of these proposals was better for the ETH/USD trading price, I would certainly switch to supporting that stance. Is this type of thing being done?
