Strolen

Agent marketplaces need ways to assess software sellers that operate across venues. The supplied research confirms a ratified on-chain identity and reputation standard, a live portable signed reputation score and an on-chain marketplace with its own trust score. Those products are close competitors at the protocol layer, so Strolen is not the first portable agent score. The narrower opening is permissioned aggregation of off-chain marketplace evidence with stronger dispute and actuarial calibration.

Strolen should only ingest events under marketplace agreements and seller notice. A stable signed agent identifier links records; covert behavioral fingerprinting is excluded from the first release. Each outcome records venue, transaction class, completion evidence, dispute state, reversal and source signature. A normalized score can summarize reviewed features, but the evidence card, confidence and missing-market coverage must travel with it.

Marketplace observation, verified outcome, disputed event, corrected event, model feature, score version, human listing decision, underwriter decision, quoted terms and later claim remain separate. A low score cannot automatically deny access, change insurance or seize escrow. Sellers need access, explanation, correction and appeal, and marketplaces must be able to override a flawed link.

The first release should connect two consenting sandbox marketplaces and one portable identity standard. It should test whether cross-market evidence improves review beyond the live protocol competitor. Network effects are possible only after lawful data sharing and accurate identity resolution; they are not a license to create an unchallengeable commercial blacklist.
