Sapien operates as an open protocol designed to source verified human knowledge on a large scale. Its contributor network includes millions of individuals from over 100 countries, encompassing professionals such as doctors and engineers as well as artists and students. These participants generate high-quality AI training data, which is validated via Sapien’s onchain Proof of Quality system. This framework allows enterprises and AI developers to obtain trusted, human-in-the-loop data, while simultaneously converting fragmented online tasks into a sustainable, reputation-based career path. The $SAPIEN token, an ERC-20 asset on Base, powers incentives throughout the network.
