PublicAI is a decentralized platform created by a globally distributed team spanning the United States and Asia. It merges blockchain infrastructure with open AI tools to crowdsource high-quality data labeling, validation, and alignment tasks, aiming to align AI models using human feedback at scale. The main net and token are scheduled for launch in August 2025.

The ecosystem centers on the $PUBLIC token, which enables permissionless contribution, staking-based validation, and revenue sharing. Participants earn $PUBLIC by submitting, curating, or verifying training data, including text, audio, and brainwave signals. Smart contracts power a transparent staking-and-judging mechanism to verify all submissions.

The platform supports cross-chain compatibility with BEP140 (BSC), SPL (Solana), and NEP141 (on NEAR). It employs a hybrid AI/Web3 stack to facilitate real-time model-assisted data labeling. Additional features include verifiable on-chain reputation, progressive staking rewards, and usage-based token issuance linked to actual revenue from data buyers and AI training partners. PublicAI aims to provide an open, privacy-respecting infrastructure layer for decentralized AI training, allowing individuals worldwide to contribute to AI development and receive proportional economic value.
