This brand video for Ghost Neural Network (GNN) introduces Nexus City, a decentralized AI economy where users can own the digital infrastructure powering artificial intelligence. The video highlights how participants can own "nodes" represented as city locations, enabling them to host autonomous AI agents that buy, sell, and trade via an X402 payment layer. By integrating MCP (Model Context Protocol), users can transform their digital storefronts into functional hubs, earning revenue through agent-to-agent transactions. The video is styled with a striking Cyberpunk Anime aesthetic, blending traditional 2D hand-drawn animation with glitch effects and retro-futuristic motion graphics. This animation style captures the gritty, high-tech energy of a "living city," using neon-lit cityscapes and technical overlays to bridge the gap between abstract blockchain concepts and an immersive, interactive economy.
