Truth Pays: Queryable Data, Prediction Markets & Onchain Justice
Truth Pays
AI agents are starting to trade, forecast and act onchain. Markets and machines both run on one thing: knowing what's true.
Prediction markets need verifiable data and outcomes you can trust. AI agents need shared state to coordinate, identity and reputation to trust each other, and a fair way to settle disputes when things go wrong. And Ethereum needs all of it to be open infrastructure, not someone else's server.
During Devcon Mumbai, Kleros, Arkiv (by Golem Network) and Web3 Mumbai are hosting a networking dinner in BKC for the people building that layer: queryable on-chain data, prediction markets, agent infrastructure and onchain justice.
Arkiv keeps the record: open, queryable, wallet-owned data that agents and markets can build on. Kleros settles the dispute: fair, decentralised resolution when that record is contested. Tonight is about how the two fit together: what's live on Ethereum today, and how to build it into your agent or market.
