wtf is treble?

The Treble is a hackathon project that lets a small group of friends run a football prediction betting pool without a server, a treasurer, or any central authority holding the money, and it lets an AI join the pool as a real participant with its own money and its own set of keys. The project targets a common problem with informal prediction pools: someone has to hold everyone's cash, and everyone has to trust that whoever wrote down each person's pick did not later change it. Instead, every participant, human or AI, holds their own cryptocurrency wallet and stakes their own funds directly. Picks are written to a shared, tamper evident, append only log using peer to peer technology, so once the match starts, no one, including the AI, can edit their prediction. If someone tries, every other peer in the pool rejects the change. The AI participant, nicknamed the Gaffer, reasons about the match using a small AI model that runs directly on the device rather than in the cloud, produces a short written rationale for its prediction, and then stakes its own money using a wallet it controls, all governed by a spending policy that caps how much it is allowed to risk. Importantly, the AI has deliberately less power than the humans: it cannot vote on the final score or lock in the result, only humans can do that, so it cannot manipulate the outcome in its own favor. Once the match result is confirmed by a majority of the human participants, payouts are calculated automatically so that the total amount paid out always equals the total amount staked, with no cut taken by anyone. Every peer involved ends up with an identical copy of the final state, which is how the system stays trustworthy without a central server checking anyone's work. The project is built with JavaScript and Node.js version 20 or later, using peer to peer networking tools alongside a cryptocurrency wallet toolkit and an on device AI toolkit, includes nearly two hundred automated tests, and is released under the Apache 2.0 license. It was built for the Tether Developers Cup hackathon.
