ProofArena is a project built for a hackathon where two automated trading agents compete against each other using live sports betting odds from soccer's World Cup, with every result recorded on the Solana blockchain so nobody can quietly edit the history afterward. The two agents watch the same data feed of odds movements. One agent, called the Steamer, bets that a sudden shift in the odds will continue. The other, called the Fader, bets that the market has overreacted and will bounce back. Each decides how much to risk using a sizing method from finance called fractional Kelly. Before a match kicks off, both agents' bets and reasoning get written to the blockchain, and the system is built so that nothing can be added or changed after that point, since the blockchain itself keeps track of the exact time. After the match ends, the actual result is checked against a cryptographic proof called a Merkle proof, which confirms the real outcome without anyone being able to fake it. The smart contract that runs all of this has no way to delete or edit a past bet, so even the project's own mistakes stay publicly visible rather than being hidden. The project includes a live public website showing a running scoreboard between the two agents, called Steamer and Fader, along with links to every recorded bet and its blockchain proof. There is also a demo video and an explanation of how the underlying strategy math works. To try it yourself, you install the project's dependencies with npm, then run the agent in paper mode, which does not need any special keys beyond access to the odds data source. There is also a live mode that actually commits bets to the blockchain, which requires an operator key file and additional access credentials. A small local dashboard can also be run using Python's built in web server. The project is released under the MIT license.
