The Last Mile Problem for Decentralized Finance
While blockchain solves trust, it still depends on traditional internet infrastructure—ISPs, DNS, CDNs—creating centralization chokepoints. Meshtastic and Meshcore enable a fully decentralized physical layer where transactions propagate through mesh networks independent of any corporation or government.
