While we haven’t yet discussed predicting how much cred a contribution will make at the algorithmic level (afaik), the main mechanism for accruing value to the Grain token is Boosting, which creates a prediction market on which contributions will increase in cred over time. So players of the “SourceCred game” will be financially incentivized to use whatever means at their disposal (including algorithms presumably) to make predictions, creating “prospective” cred.
I haven’t seen this talked about yet (doesn’t mean it hasn’t:) But the graph is a rich source of data for all sorts of analysis. Plenty of ideas generally around that.
