MicroStream - Pay-Per-Second Micropayments on Qubic MicroStream solves the micropayment problem that has plagued blockchain for years. On Ethereum, sending $0.001 costs $5 in fees - making micropayments literally impossible. MicroStream leverages Qubic's zero-fee architecture to enable viable pay-per-second streaming payments. The system features a live counter that updates every second, showing viewers exactly how much they've paid and creators how much they've earned. Payment channels allow indefinite streaming with only two on-chain transactions: opening and closing the channel. Key features include zero transaction fees, instant 2-3 second settlement, pause/resume functionality, and automatic refunds of unused deposits. The tech stack spans a C++ smart contract with 5 core functions, Node.js backend with demo mode, vanilla JavaScript frontend with real-time counter, and 4 automation workflows for creator alerts. This enables new business models: students paying per second for lectures, gamers renting servers by actual usage time, artists earning fairly per play, and developers paying per API request. Only possible on Qubic. The combination of zero fees, instant finality, and 15.5M TPS capacity makes MicroStream the first viable micropayment system in blockchain history.

In this hybrid hackathon powered by Arc, developers will build the next generation of agentic commerce systems using Arc with USDC. Explore a world where AI agents and web services can pay for APIs, data, compute, and content in dynamic, usage-based ways, while Arc provides stablecoin-native settlement with predictable USDC fees and deterministic, sub-second finality. This hackathon is supported by Google & Google DeepMind, with a dedicated challenge and $40,000 in Google Cloud Platform (GCP) credits awarded for the best use of Gemini models and Google AI Studio. 📅 January 9 – 24, 2026 • Jan 9 – 23 (Online Phase) – Collaborate and build online with developers and AI innovators from around the world.
