https://github.com/hCaptcha The hCaptcha marketplace is powered by the HUMAN Protocol, an open decentralized protocol for human review that runs on the Ethereum blockchain. Websites earn Human Tokens (HMT) whenever users use the hCaptcha widget on their site, and machine learning companies pay Human Tokens to get their data labeled.
