Why was this funded?
Each verifier signs with its own NEAR account and key. In this demo the LifeLine team runs all four.
Spatio-temporal cluster verified: source_diversity=5, max single-source share=20.0% (<=40%), radius=288m, window spread=3000s.
Claim verified by 3 independent external sources: (1) open-meteo recorded 112.4mm/24h extreme rainfall anomaly, (2) gdacs issued a Red Flood Alert for Maiduguri/Borno State, and (3) reliefweb published UN OCHA Flash Update #1 confirming the Alau Dam breach.
The lowest ask under the cap wins, if the responder meets the reputation and delivery time rules.
NEAR Intents can deliver a payment as USDC on another chain. The quote is live from the 1Click API as a dry run, so nothing moves. Sending the payout this way is coming next.
This pool pays a testnet token, and NEAR Intents has no testnet, so the quote prices the same amount of real USDC on NEAR mainnet.
Reports stay off chain to protect the people who sent them. Only this record's hash is stored on NEAR.
“Water from Alau Dam has breached river banks into Gwange and Maiduguri central. Streets under 1.5m of water, families trapped on roofs.”
“Urgent: Custom Bridge and Lagos Street in Maiduguri overtopped by rapid flash floodwaters following Alau Dam overflow. Evacuation boats needed.”
“Heavy flooding across Maiduguri metropolitan area since 4am. Over 500 displaced households gathering at high ground near post office.”
“Confirmed dam breach impact in Maiduguri. Clean water sources contaminated, immediate shelter and WASH kits required for displaced families.”
“Shehu's Palace area and Monday Market surrounded by deep flood water. People need rescue and dry rations immediately.”
Proposing Severity Tier 3 (Major Regional Disaster): Alau Dam spillway failure combined with 112.4mm/24h rainfall and a GDACS Red Alert has submerged multiple Maiduguri wards (Gwange, Custom, Shehuri) with >500 households immediately stranded.
Proposed tier Tier 3
Objection is fully rebutted by 3 independent external sources: Open-Meteo confirms an extreme 112.4mm/24h downpour, GDACS issued a Red Flood Alert specifically for Borno State/Maiduguri, and UN OCHA ReliefWeb confirmed the Alau Dam breach.
Strongest objection. Field reports could be exaggerating routine seasonal rain into a dam breach emergency to trigger higher-tier payouts.
