Arbitrum Open House India: Online Buildathon

TreeView

TreeView is the world’s first 4D semantic mapping network, capturing not just the geometry of the Earth (X, Y, Z) but also the dimension of time (T). Unlike traditional maps, TreeView doesn’t just show where things are—it shows how they change and what they mean. By fusing AI and blockchain, TreeView transforms everyday videos and sensor data from smartphones, dashcams, drones, and satellites into living, dynamic maps. Contributors are rewarded through a unique scoring mechanism where data quality is evaluated every minute, linked directly to on-chain token emissions. This hybrid AI + DePIN + Web3 approach positions TreeView as the foundation for next-generation applications: from environmental monitoring and urban planning to autonomous navigation and climate intelligence.

DigiRobotics

DigiRobotics is the world's first AI-native marketplace for audio-visual robotics training data. We tokenize unique, first-person Real World Asset (RWA) data ~ representing human labor and physical knowledge ~ into verifiable on-chain assets (ERC-721/1155). These tokenized datasets generate real, sustainable yield in Paxos stablecoins (USDG/PYSUD) when purchased autonomously by robotics R&D teams via our x402 agentic payment rails.
