Conjecture

Hidalgo's complexity index values a country by how many things it makes, weighted by how few others make them, iterated until stable; ranked that way small sophisticated economies rise above big ones, and the index predicts future income. The same recursion run on a contributor-by-claim matrix would value a contributor by the rare, hard claims they back and a claim by how capable its backers are: a credit score that pays for scarce knowledge rather than volume, and that cannot be gamed by flooding the commons with easy claims.
