# { "Depends": "py-genlayer:1jb45aa8ynh2a9c9xn3b7qqh8sm5q93hwfp7jqmwsfhh8jpz09h6" } """ Scuttlebutt — RumorCourt v1.7 A real-time natural-language claim-verification market. Validators fetch caller-declared, time-bounded sources (Wayback + the https URL itself), reach consensus on TRUE / FALSE / UNVERIFIABLE, and stakers are paid with a time-decay weighting. RESOLUTION SAFETY ----------------- create_claim requires 1–3 https source URLs. Search engines and shorteners are rejected. At resolve the leader fetches only those URLs plus the Internet Archive snapshot closest to the deadline. Snapshots must be dated at or before the deadline — not one second later. Older snapshots are valid. Missing, post-deadline, or noisy evidence fails closed to UNVERIFIABLE. SETTLEMENT SAFETY ----------------- total_winner_weight is O(1): weight_i = amount_i * (resolved_at - ts_i + 1) sum_i weight_i = (resolved_at + 1) * stake_winning - sum_amt_ts_winning sum_amt_ts_* is maintained on every stake. Resolve never loops stakers. A claim also caps unique stakers so get_claim cannot blow up. list_claims only walks the newest MAX_CLAIM_SCAN ids (newest-first), skips `offset` matches, then materialises at most `limit` summaries. It never builds an unbounded matched list. TIME-DECAY PAYOUT ----------------- payout_i = amount_i + (weight_i * losing_pool) // total_winner_weight UNVERIFIABLE refunds principal. Dust stays. No owner.
