Proof of Humanity, developed by Kleros, is a pioneering blockchain-based verification protocol and registry that reflects the ongoing shift towards on-chain interactions. This innovative platform enables individuals to create and submit their profiles while also allowing them to vouch for the credibility of others. Moreover, users have the ability to raise concerns about suspicious individuals within the system.

At its core, Proof of Humanity operates as a fully decentralized protocol. To efficiently organize and access its vast amount of data, the platform leverages subgraphs within the Graph protocol. This ensures seamless indexing and retrieval of information, further enhancing the overall user experience.
