Hackathon

Amazing hackathon project

Marmot is a protocol for efficient end-to-end encrypted group messaging over nostr relays, built for humans and agents. Think Signal, but unstoppable and doesn‘t need your phone number to work. Your challenge, if you choose to accept it, is to build something wildly creative and devilishly practical that helps user’s protect that privacy.

Only eligible to teams where EVERY member is a first-time contributor to open-source bitcoin

A home miner is a heater that earns bitcoin. This prize goes to the best project built on MDK, the open-source Mining Development Kit, that makes mining useful at home: it heats what needs heating, reacts to what’s happening in the house, and runs without supervision.

You can build an MDK app, a Worker for a device MDK doesn’t support yet, or both. Some ideas, not a checklist:

• Heat a pool, hot tub, water tank or greenhouse, mining only as hard as the heat is needed
• A comfort controller that runs miners based on room temperature, air quality and quiet hours
• Mine on solar surplus or off-peak power, and back off when electricity gets expensive
• Show the real cost of heat: sats earned versus a regular electric heater

No hardware needed: you can build against MDK’s mock environment. Docs: https://docs.mdk.tether.io · Code: https://github.com/tetherto/mdk

A mining site is one of the most flexible large loads on the grid: it can shed power within seconds and bring it back on demand. This prize goes to the best project built on MDK that turns that flexibility, and the data behind it, into value for operators, energy producers or the grid.

You can build an MDK app, a new Worker, or both. Workers can wrap APIs too, such as a power-price feed or a grid signal. Some ideas, not a checklist:

• Curtailment: throttle or power down automatically on price spikes, grid alerts or a site power cap, then ramp back safely
• Demand response: answer grid signals fast enough to sell flexibility, and prove the megawatts delivered
• Profit-aware control: set each machine’s power target from hashprice, energy cost and its own efficiency
• Follow the output of a solar or wind farm, or a flare-gas site
• Site health: catch failing machines, hot spots or cooling problems early, or build an AI agent that proposes fixes for an operator to approve

No data center needed: you can build against MDK’s mock environment. Docs: docs.mdk.tether.io · Code: https://github.com/tetherto/mdk
