I just came across this paper, which I believe was also discussed at IIW. It is from LF, DIF, etc. Notably, it contrasts itself to the “centralized” systems such as GAFA or Global biometric database such as World ID (according to their characterization. I do not necessarily agree.)
A short summary created by NotebookLM.
The First Person Project (FPP) is an international, multi-stakeholder effort dedicated to building a functioning trust layer for the Internet. Its urgent mission is to solve the problem of proof of personhood (PoP), exacerbated by generative AI’s ability to impersonate humans. FPP achieves this by establishing a decentralized trust graph. This graph utilizes two core types of verifiable credentials (VCs). Personhood Credentials (PHCs) attest that a holder is a unique person within an ecosystem (e.g., a university or government). Verifiable Relationship Credentials (VRCs) are issued peer-to-peer to verify authentic, first-person trust relationships. The system is decentralized and privacy-preserving, using zero-knowledge proofs (ZKPs) so sensitive data is not tracked in global databases. FPP relies on foundational standards like Decentralized Identifiers (DIDs) and the Trust Over IP (ToIP) stack. The Linux Foundation is “customer #1,” implementing FPP to protect the open source supply chain from threats like malware injection attacks (e.g., the XZ attack). Ultimately, the FPP aims to establish the First Person Network Cooperative (FPNC) to govern the network as an open global digital utility
