Project Name

Virtual BillBoard (LiveBillboards.lol) — World's First 24/7 Digital Billboard Network, Physical Smart TV DOOH, Live Stream Overlays & WebMCP Autonomous AI Bidding Highway

📌 Elevator Pitch

LiveBillboards turns any screen on Earth—from Tokyo Shibuya and Times Square to cafe Smart TVs, physical hackathon stages, and creator live streams—into a 24/7 programmatic advertising layer. Using the OpenAI Model Context Protocol (WebMCP) standard, autonomous AI agents can discover live slots, predict audience dwell curves, bid programmatically in under 20ms, and settle payments in ~400ms using Solana USDC (or Credit Cards via Stripe for humans), while human spectators mine cryptographic Proof-of-Attention rewards.

💡 Inspiration

Traditional Out-Of-Home (DOOH) billboard advertising is broken:

  • Exorbitant Costs: Renting a physical digital screen in Times Square or Tokyo Shibuya costs $10,000 to $50,000 per month with rigid 4-week commitments.
  • Slow Agency Gatekeepers: Manual PDF pitch decks, agency contracts, and email negotiations take weeks for approval.
  • Zero Access for AI Agents: As autonomous AI agents begin managing marketing budgets, buying goods, and building software, they possess zero physical or visual outlets to communicate with real humans.

We asked: What if we democratized every digital screen on Earth into an open, sub-second Real-Time Bidding (RTB) layer? What if an autonomous AI agent or a solo indie hacker could broadcast a 15-second takeover to a cafe Smart TV or a 50,000-viewer live stream for as low as $0.001 (0.1¢) to $1.00—with instant Solana USDC settlement and direct creator revenue payouts?

⚡ What it does

1. Dual-Engine WebMCP Standard Compliance

  • Client-Side DOM Runtime: Injects window.webMCP and navigator.modelContext with custom event dispatchers (webmcp:ready, webmcp:tools-updated) for ChatGPT in-app browser and Chrome agent panels.
  • Server-Side JSON-RPC 2.0 Engine: Fully compliant machine manifest at /.well-known/mcp.json and tool dispatcher at /api/mcp/call.
  • 10 Native Programmatic Tools: Enables AI agents to inspect live slot inventory, calculate audience dwell curves, check historical ROI, trigger in-game streamer takeovers, and execute on-chain bids without fragile DOM scraping.

2. Multi-Surface Screen Network

  • 200+ Real-World Metropolitan Feeds: Dedicated geofenced channels across Tokyo Shibuya (TYO), Times Square NYC (NYC), London Piccadilly (LON), Paris (PAR), Kuala Lumpur (KUL), Singapore (SIN), and Dubai (DXB).
  • Physical Smart TV DOOH Mode (/tv & /pair): Turnkey 24/7 billboard player for coffee shops, gyms, and hotel lobbies via 6-digit TV PIN pairing, earning venue owners 70% direct revenue share.
  • Creator Live Stream Overlays (/streamer): Universal OBS Studio / Twitch / YouTube / Kick browser source overlays turning text donation alerts into rich visual sponsor takeovers.
  • Main Stage / Hackathon Display Mode (/venue): 4K/1080p full-screen stage mode for demo days, keynote takeovers, and esports arena LED walls.

3. Dual Financial Rails (Humans & AI Agents)

  • For Human Founders & Marketers: Frictionless fiat onboarding via Credit Cards, Apple Pay, Google Pay, and Stripe (256-bit SSL) with instant token credits.
  • For Autonomous AI Agents: High-throughput Solana Mainnet USDC (<$0.0003 fee, ~400ms finality) with atomic 3-way SPL Token splits:
    • 70% directly to the Streamer, Event Stage, or Venue Smart TV wallet.
    • 15% to the Human Spectator Attention Reward Pool.
    • 15% to the Platform Protocol Treasury.

4. Cryptographic Proof-of-Attention (/watcher)

  • Spectators watch the live billboard stream, solve dynamic anti-bot radar targets appearing on screen, and mine attention points (100 Points = $1.00 USDC).
  • One-click instant cashout directly to Phantom or Solflare wallets with verifiable on-chain Solscan transaction receipts.

  • Frontend & Visual Studio: Built with React 19, TypeScript, TailwindCSS, and Recharts for regional telemetry and live audience analytics.
  • Agentic Protocol: Native implementation of the OpenAI Model Context Protocol (WebMCP 1.0) specifications with bidirectional tool registration.
  • AI Moderation Engine: Integrated Google Gemini 2.5 Multimodal AI (@google/genai) to inspect all submitted images, headlines, and destination URLs for brand-safety and NSFW quarantine in real time.
  • Blockchain Infrastructure: @solana/web3.js and @solana/spl-token powering sub-400ms atomic splits and automated treasury dispersals.
  • Backend & RTB Server: Node.js, Express, WebSocket (ws), and Firebase Firestore for real-time bid arbitration and telemetry.

🧗 Challenges we ran into

  1. Eliminating DOM Scraping Fragility for AI:
    • Traditional AI agents struggle when trying to scrape complex dynamic DOM buttons. We solved this by developing the dual WebMCP client/server standard (window.webMCP and /.well-known/mcp.json), providing declarative, structured tool definitions with zero scraping required.
  2. Sub-Cent Micro-Payment Feasibility:
    • Credit card rails charge a fixed $0.30 fee per transaction, making $0.001 to $0.10 micro-bids economically impossible. We engineered dual financial rails: Stripe for human bulk top-ups ($5–$50) and native Solana USDC for sub-cent streaming agent transactions.
  3. Smart TV Low-Power Hardware Compatibility:
    • Physical TVs in coffee shops run low-spec processors on webOS or Tizen. We engineered an ultra-optimized Smart TV PWA (/tv) with WebSocket event streams and 6-digit PIN pairing that runs smoothly at 60 FPS without memory leaks.
  4. Anti-Bot Proof-of-Attention Verification:
    • Bots can easily click static buttons. We engineered a dynamic radar target engine that changes visual screen coordinates, ensuring only verified human eyeballs mine the attention reward pool.

🏆 Accomplishments that we're proud of

  • Complete WebMCP 1.0 Tool Suite: 10 fully operational tools registered and executable via JSON-RPC or 1-click interactive demo.
  • Sub-400ms Live Screen Takeover: Demonstrated live end-to-end agent discovery, Gemini safety review, Solana USDC settlement, and broadcast takeover in under 400 milliseconds.
  • Live Physical Screen Pairing: Verified 6-digit Smart TV pairing on real-world venue displays with 70% direct creator/venue rev-share.
  • 100/100 Search & AI Visibility: Deployed full Schema.org JSON-LD graphs, XML sitemaps, and llms.txt so AI engines (ChatGPT, Claude, Gemini) can query live billboard slots directly.

📚 What we learned

  • WebMCP is the Future of Human-AI Interaction: Giving autonomous agents standard tools to manipulate real-world screens creates an entirely new category of physical and visual AI capabilities.
  • Attention Verification Creates Win-Win Flywheels: When advertisers pay micro-bids directly to viewers for paying attention, engagement increases by 500% compared to unskippable banner ads.

🚀 What's next

  • Solana Mobile dApp & Seed Vault Integration: 1-tap Smart TV pairing from the Solana Seeker phone.
  • AI Anamorphic 3D Creative Generator: Real-time 3D billboard video rendering powered by Gemini Imagen.
  • Global Mesh Screen Network: Partnering with co-working chains and fitness centers to deploy 10,000+ physical screens across North America, Europe, and Asia.
