Every dot is a live MeterCall L4 node. Color = hardware class. Size = PCP earned. A Raspberry Pi 3ms from the caller beats AWS us-east-1 at 50ms — every call is settled by whoever replies fastest, and the reward curve pays for that.
Projection: equirectangular. Lon −180..180 → x 0..1000. Lat 90..−90 → y 0..500. Live data polls /api/node/coverage-map every 30s. Coverage gaps surfaced by BOT #97 GEO_BALANCE_BOT.
Short version: every L4 call is a race. Local nodes win, distant ones lose. The reward curve pays fastest first. See Economics for the full table.
