Poseidon

Poseidon is a decentralized data layer developed on top of the Story Protocol, offering AI developers access to high-quality, legally licensed training data. Created by the Story team, it solves the pressing issue of IP-safe datasets by using Story’s programmable IP tools and tamper-proof registry.

What is Poseidon

Poseidon is a full-stack, decentralized data layer for AI, purpose-built on Story to bring real-world data into the next wave of AI innovation. It combines structure, licensing, and incentive alignment in a way that turns scattered, high-value edge-case data into something composable and accessible for builders.

At its core, Poseidon is designed to make the hardest-to-source data usable at scale. That means robust metadata and standardized formats for multi-modal input. It means ingestion pipelines that work for sensor data, not just scraped text. And just as critically, it means IP clarity from day one so that contributors can share data confidently and model developers can use it commercially, without risk. Poseidon is built on top of Story’s licensing infrastructure, which means every dataset can carry its own terms, provenance, and logic for how rights and revenue flow.

Poseidon isn’t just infrastructure, it’s a new economic layer for AI, one where long-tail, high-signal data can be shared safely and fairly without being trapped in institutional silos or lost in legal ambiguity.
