AnonMarket: Revolutionizing Privacy in Predictive Markets

Meet Charles-André Goichot (LinkedIn), Ewan Hamon (LinkedIn), Mathis Sergent (LinkedIn), Mathieu Laruelle (LinkedIn), and Marc Bertholat (LinkedIn) — an innovative team of students from Paris. They joined forces at ETHGlobal Bangkok 2024 to develop AnonMarket, a privacy-first predictive market platform that leverages Alice’s Ring signatures to ensure user anonymity.

With AnonMarket, users can securely and anonymously bet on outcomes like Bitcoin’s price in two months or the next U.S. president, combining transparency and privacy. As Charles-André explained, “The goal is that your interaction with the prediction market is anonymous. We know you interacted, but we don’t know which market you bet on or the side you took.”

The team chose to build on Rootstock for its robust security and compatibility with Ethereum tools, which made their development process smooth. “The EVM compatibility meant we weren’t lost—we could use tools we already knew, like deploying and verifying contracts,” they shared. Despite the intense 36-hour hackathon, the team enjoyed moments of camaraderie and creativity, fueled by sleepless nights and shared determination.

For those inspired by AnonMarket, more details can be found on the ETHGlobal Project Page, and the source code is available on the AnonMarket GitHub Repository.

Their advice for future participants? “Brainstorm your idea with your team before the hackathon so you can focus on building when it starts. And don’t hesitate to talk to the sponsor teams—they’re always there to help,” Ewan suggested.
