Decentralized Identity Verification using Zero-Knowledge Proofs: A Privacy-Preserving Authentication Framework
In the contemporary online interaction, digital iden- tity is central, but most systems follow a centralized provider like Google or Facebook. Although convenient, these models pose ma- jor risks to data breach, surveillance, and single point of failure. The proposed paper proposes a privacy-sensitive decentralized identity verification system that uses Zero-Knowledge Proofs (ZKPs) to allow users to make it through claims (e.g., age, citizen- ship, or enrollment) without any personal data being provided, thereby solving the challenges outlined in the paper. Our architecture integrates verifiable credentials, zero-knowledge-SNARKs and an issuer trust registry that is maintained on blockchain smart contracts to guarantee trustless verification and eliminate dependence on centralized authorities. Its system gives its users full control over credentials, allows reuse across applications, and does not expose data.A proof-of-concept implementation has shown the approach to be feasible with Circom and SnarkJS to generate proof, Solidity smart contracts to verify them, and a user interface implemented in React. Results of the evaluations showed that determination of the verification latency is low, the overhead to generate proofs is moderate, and no privacy leakage occurs. It can be used in potential applications such as education, e-governance, healthcare, finance, and online voting.
Privy Blog | Privy and Stripe: Bringing crypto to everyone
We started Privy a little over three years ago to make it easy for any developer to build better products on crypto rails. Whether crypto is core to your app or simply a new layer of functionality, a good crypto product should just feel like a good product, period. By making crypto usable, we help make it useful for everyone.
Keytrace takes ideas from Keybase and Keyoxide and brings them to the decentralized web.

BeeKEM: Decentralized, Secure and Efficient Group Key Agreement
Group key agreement protocols are essential for modern secure messaging. Most existing group key agreement protocols assume a centralized model with a semi-trusted service that mediates the communication. This is efficient, but problematic for some important applications, since a central service can be a choke point for surveillance and censorship. There is a nascent literature on decentralized group key agreement that avoids such reliance, but existing proposals either do not scale, with update costs linear or quadratic in the group size, or lack proofs of security. Centralized protocols can offer much lower (logarithmic) cost. We present BeeKEM, the first decentralized group key agreement protocol with logarithmic update cost in the common case (degrading to linear in the worst case) and proofs of security. We provide an open-source implementation and demonstrate that it is competitive with OpenMLS. BeeKEM opens the door for a range of communication and collaboration applications offering not only end-to-end encryption, but also metadata privacy and censorship resistance.
