VoltNet

Inspiration

Seeing multiple people producing and selling things amongst themselves, it got me thinking about power distribution and consumption between houses.

What it is

VoltNet is a decentralized peer-to-peer micro-grid energy market clearing engine. It simulates neighborhood homes that generate, consume, store, buy, and sell electricity in real time. The goal is simple: homes with excess electricity can sell it locally at a fair price, while homes with higher consumption can buy from nearby providers using real wallet settlement logic.

What it does

• Simulates a local micro-grid with solar producers, consumers, batteries, wallets, and live telemetry.
• Opens short market rounds where nodes submit buy bids and sell asks.
• Clears the market with a double-auction matcher.
• Settles trades by actually debiting buyer wallets and crediting seller wallets.
• Prevents overdrawn wallets and unpaid fills.
• Streams telemetry, orders, round state, and ledger events to the dashboard over WebSockets.
• Persists nodes, market orders, wallets, and ledger records in PocketBase.

How we built it

we built it using : Backend: FastAPI, Python, async WebSockets Market engine: custom Python double-auction matcher and settlement flow Data store: PocketBase Frontend: Next.js, React, TypeScript, Tailwind CSS, shadcn-style UI components Package manager: Bun for the frontend

Challenges we ran into

making a ledger from scratch is something I've never done, and also making a real time bidding system.

Accomplishments that we're proud of

I implemented a real time autonomous bidding system that buys and sells goods [electricity] over a decentralized network of nodes.

What we learned

I learnt how to simulate an interconnected IOT of nodes (houses in this case) and use their shared data over a database to make a real world application of IOT and blockchain technologies.

What's next for VoltNet

idk, I think it needs a lot more work than what hackathon project does.
