Overview
Over the past three months, three incredible projects from the DIF Labs Beta Cohort 2 have been working intensively to refine and advance groundbreaking proposals since beginning their development phase on June 24, 2025. These projects represent cutting-edge innovation in decentralized identity, tackling real-world challenges with fresh perspectives and novel approaches.
The DIF Labs Show and Tell is the culmination of this journey—a chance to showcase the hard work, insights, and progress made during the cohort. This is your opportunity to see these projects in action, engage with their creators, and contribute to the vibrant ecosystem of decentralized identity.
Please join us on September 23 to hear from these projects and learn more about what they’ve accomplished.

Project Details
Legally-Binding Proof of Personhood for Verifiable Credentials via QES
Timeline: May 31, 2025 - August 31, 2025
Leads: Jon Bauer, Roberto Carvajal
This proposal creates a standardized method to anchor Verifiable Credentials to legally recognized, high-assurance proof of an individual’s identity through Qualified Electronic Signatures (QES). QES, recognized by eIDAS in the European Union, represent the highest level of electronic signature, carrying the same legal weight as a handwritten signature. By creating a standardized mechanism to attach a QES to any VC, we can bind that credential to the strong proof of personhood and KYC attributes inherent in the QES.
Privacy-Preserving Revocation Mechanism
Timeline: May 20, 2025 - August 31, 2025
Leads: Kai Otsuki, Ken Watanabe
This project delivers a comprehensive analysis of privacy-preserving revocation mechanisms for Verifiable Credentials. It catalogues real-world revocation scenarios, benchmarks leading cryptographic mechanisms (status lists, dynamic accumulators, zk-SNARK proofs, short-term credentials), and provides an open-source prototype that evaluates computational costs for Issuers, Holders, and Verifiers. The work bridges the gap between cryptographic research and practical VC deployments.
Anonymous Multi-Signature Verifiable Credentials
Timeline: May 20, 2025 - August 31, 2025
Leads: Seohee Park, Lukas Han
This proposal outlines a protocol for VC issuance that requires m-of-n multi-signature approval while maintaining anonymity of individual signers. Using Semaphore, it enables decentralized governance for VC issuance in organizations such as DAOs or government agencies, cryptographically proving sufficient participation without revealing the identities of participating members. The protocol maintains compatibility with existing VC formats like W3C VCDM and IETF SD-JWT VC.
