Could you maybe have a system where if someone thinks a supernode is not being correctly weighted they can dispute it by creating an Issue around it and boosting that Issue. Then SourceCred community members would be incentivized to engage with that Issue. This could lead to a problem being explored and either discarded or resolved. If Cred weighted voting gets enabled then there could be a vote to resolve it as well.
To take this even further, since boosting is kind of a prediction market on ideas you could boost an Issue, then have a futarchy market open on that Issue. As people engage with the Issue to help resolve it, they could vote on which way they think the dispute will go (was the supernode being fair or not), and then as the discussion evolves there’s a tangible signal as to how it’s going. Then when the market resolves (say after 7 days or something) those who voted with the winning side get rewards from the boost and those that didn’t might have some Cred flow to the winners.
