🏭 Urban Lab: Building a Sustainable Mobility Ecosystem with

Urban Lab seeks to create a sustainable mobility ecosystem by integrating smart electric scooters, AI-powered services, open-source software and privacy-focused payments. Key components of the ecosystem include:

🔐 Monero 2-of-3 multisig escrow

🤖 AI and robot integrations

🐛 Automated GitHub bounties

💰 MYZ reward accounting

💱 Experimental MYZ → XMR conversion logic

📊 Real-time monitoring

🌐 MyZubster integration

This article provides a technical overview of the project, including testing methods and future work needed. It is crucial to note that the system is still experimental and only uses simulated data or Monero Stagenet for testing. Any examples of MYZ → XMR conversions are application-level simulations unless mentioned otherwise. The project does not claim to be a production financial service.

The Urban Lab concept begins with the idea of combining physical vehicles, AI, open-source software and privacy-focused payments to create a smart mobility service. The scooter concept includes GPS tracking, remote locking, AI integration, digital payments, and automated service workflows. Adding a payment system raises the question of how to reduce trust between customers and service providers. This is where escrow comes in.

🔐 Monero Multisig Escrow

The experimental escrow architecture uses a 2-of-3 multisig model, involving three participants: the buyer (customer), the seller (service provider), and an optional admin/arbitrator. A simplified workflow for the escrow process is as follows:

1. Customer creates an escrow request

2. Buyer and seller authorize the transaction

3. Admin (optional) may also authorize the transaction

4. Threshold is reached, and the application updates the escrow state

5. Release workflow is executed

The backend system manages escrow management, including unique escrow IDs, transaction state, participant information, authorization tracking, cancellation, expiration, and monitoring. The technology stack includes Node.js, Express, MongoDB, Monero Wallet RPC, WebSocket, HTML/JavaScript dashboard, and Monero Stagenet.

Another aspect of the ecosystem is the experimental GitHub bounty system, which allows GitHub issues to contain bounty declarations. When conditions are met, the application records the reward in the contributor's MYZ balance, connecting open-source contributions to automated rewards and ecosystem balance.

🐛 Automated GitHub Bounties

The GitHub bounty system has the following API endpoints:

POST /api/bounties - Create a bounty

GET /api/bounties - List bounties

GET /api/bounty-history - View bounty history

GET /api/user-balance/:username - Check MYZ balance

The system is designed to automate accounting, not to replace GitHub's security model. Webhook authentication and authorization are essential before production deployment.

📊 MYZ → XMR Conversion

Urban Lab is also experimenting with a MYZ → XMR conversion layer. The conversion API allows for:

GET /api/exchange-rate

POST /api/convert-myz-to-xmr

GET /api/conversion-history

Please note that the term "SIMULATED" is crucial, as an application-level exchange rate does not create a real market or redeemable asset. Before deploying a real conversion system, additional work is required regarding custody, liquidity, pricing, security, and applicable regulations.
