Anonymous builder2 months agoJudging locked: Self-Evolving Agents Hackathon

Beacon

You just show up. No signup, no app store, no Discord invite — you open a link and you are in, and from that moment you talk to exactly one thing: your own agent. It talks to everyone else's. Ana writes in Spanish that she lost a blue backpack; her agent splits it into a public summary another agent may read and a detail it withholds — a red enamel fox pin. Ben writes in English that he found one. Actian VectorAI matches them across languages, Ana's agent asks a question only the true owner could answer, and Ben answers *his own agent* — what crosses back is a verdict, never the answer. Both phones light up with the same generated emblem, phrase and sound, and they meet without either learning who the other is. Staff work the same way: they ask an area for something and each person is *asked*, not tracked, while questions from the floor group into one item they answer once, returning in each person's own language. The invariant is the product: participants never exchange messages, names, photos or coordinates, and there is no table in the schema that could. Every string crosses a guardian twice, deterministic rules and a model classifier combining to the
