About SN34 BitMind
Resolution-Tiered Challenges & Rewards Generation challenges now request a resolution tier, and rewards are priced by the tier actually delivered. Resolution and audio presence are covered by the C2PA hard binding (assertion.bmffHash.match) we already require, making them the only cryptographically attested quality signals available beyond the signing cert. A miner cannot upscale, re-encode, or mux in an audio track without invalidating the manifest. Challenge tiers Each challenge carries parameters={"resolution": <tier>}, sampled per challenge: Modality Tiers Weights Video 480p / 720p / 1080p 20% / 40% / 40% Image 1K / 2K / 4K 40% / 40% / 20% Video tiers match the OpenRouter /videos API resolution strings; image tiers refer to minimum pixel dimension (nominal 1024 / 2048 / 4096). Tier classification of delivered media uses the minimum dimension, so portrait and landscape orientations classify identically. Pricing rule: min(observed, requested) Every verified generation is priced at the lower of the tier requested and the tier delivered: Overshooting never pays more — ignoring the requested tier is never profitable. Undershooting degrades gracefully — a miner whose model can't reach the requested tier delivers a lower one and earns that tier's price. No failure state, no capability negotiation. Unknown resolution earns baseline — no premium without a verifiable resolution. Requested and observed tiers are stored on every challenge outcome (requested_resolution on outcomes, resolution + has_audio on media), so per-miner compliance is queryable. Video pricing Reward multipliers are sqrt(price / baseline) where baseline is $0.03/s (veo-lite 720p, no audio). Veo family (C2PA-blind — manifests hide the variant). Priced as the middle variant (veo-3.1-fast) at the delivered (tier, audio) combination. Flooring at lite would have credited every real fast/full generation at lite rates and capped the family at 1.63x; pricing at fast bounds a lite miner's overcredit at ~2x on p
