Proof of Alpha Network: A Reputation Layer for Market Opinions Most social platforms measure attention through followers, impressions, likes, and reposts. These signals show who commands an audience, but they do not answer the question that matters most: Who has demonstrated repeatable market insight? Proof of Alpha Network introduces a reputation layer for public market opinions. It converts unstructured commentary into timestamped, testable records containing the relevant asset, direction, time horizon, and clarity of the original call. Each opinion is then evaluated against what subsequently happened in the market. This creates an inspectable history of the call, its outcome, and the evidence used to assess it. Reputation is not reduced to a single universal score. A source may demonstrate strong insight into Bitcoin while performing poorly in equities. Someone may excel at long-term macro analysis but struggle with short-term market timing. Proof of Alpha therefore builds contextual reputation across assets, time horizons, market regimes, and consistency. These relationships form an opinion graph connecting people, opinions, assets, events, and outcomes. At its core is the Alpha Oracle, an ensemble system in which multiple independent AI models evaluate the same source material. Their weighted agreement determines whether an opinion record can be committed automatically, requires further refinement, or should be excluded when the evidence remains too ambiguous. The resulting network continuously updates through the evolving loop: Opinion → Outcome → Reputation → Trust → Conviction The same structured records can also serve AI agents. By converting fragmented market discourse into a shared format, Proof of Alpha allows information to move across an agent network without every agent repeatedly interpreting the original content. Proof of Alpha doesn’t replace judgment or predict future returns. Instead, it makes the historical evidence behind market credibility visible. Markets have always priced assets. Proof of Alpha begins pricing credibility.
