Physical AI is starving for data that satellites and fleets simply can't capture. Language models already hit the text wall. The next bottleneck is the real world: stairwells, loading bays, market streets, warehouse interiors, and sidewalks that no overhead map sees clearly. Robots and world models need dense, ground-level 3D geometry with provenance you can actually verify, not just trust. That's the gap @vangrid_io is filling. Ordinary phones become edge nodes. People film specific spots, the system reconstructs 3D models, and every capture gets fingerprinted and attested on Base so buyers can check it themselves. Bounties settle in USDC. The network is demand-driven from day one. Latest public numbers show the scale already: 1.25M+ captures, 450k+ users, thousands of attestations, and $600k+ USDC settled. No dedicated hardware fleets. No waiting for corporate mapping vans. Just people, phones, and onchain proof. The grid is growing because the alternative is simulations that keep failing in the real world.
