ZKpassport: Private Unforgeable Identity
Duration: 00:19:49
Speaker: Michael Elliot, Théo Madzou
Type: Talk
Expertise: Intermediate
Event: Devcon
Date: Nov 2024
This talk presents ZKpassport, an identity verification solution integrating zero-knowledge proofs with ePassports to achieve privacy-preserving and unforgeable government-attested digital identities. We will delve into the technical architecture, implementation challenges, and practical applications. Attendees will gain insights into the development process, benefits, and potential uses of this technology in enhancing digital identity privacy and security.

Keynote: Programmable Cryptography and Ethereum
Programmable Cryptography is a "second generation" of cryptographic primitives - primitives that allow arbitrary programs to be executed "inside of" or "on top of" cryptographic objects. Programmable cryptography provides three key affordances that complement and amplify the affordances of Ethereum--verifiability, confidentiality, and non-interactivity. We'll discuss how these technologies can reshape the Internet over the next 50 years.

Check your user's humanity, nationality or age with privacy-preserving ID proofs!
This workshop shows how to use the Proof of Passport SDK to check user's identity in a few lines of code. Let users generate zk proofs of age, nationality, humanity or non-inclusion in the OFAC list by scanning the NFC chip in their passport or ID card, and without ever having to reveal any private information. Come try it now!

Keynote: The Universal Cryptographic Adapter
The "secret" third affordance of Zero-Knowledge proof after 1) Privacy and 2) Succinctness is Interoperability. ZK enables us to continuously refactor data, aggregate it from different sources, and transforming it without loosing its integrity. Starting with the Zupass project, and now with the broader adoption of the POD and GPC format, 0xPARC has been exploring using ZK for data sovereignty and creating more interoperable data ecosystem. We will cover our learnings and progress in this talk.

Anon-Aadhaar Protocol using Halo2 and Noir
We will introduce the Anon-Aadhaar protocol which is an anonymity layer on top of a social security like Scheme (Aadhaar card) for Indian citizens using Zero-knowledge proofs. This can be used for getting many basic services in India like electricity, banking, etc. We will describe the implementation results of the protocol using Halo2 and Noir. We will also provide a comparative analysis of benchmarks using different backends like Circom, Halo2 and Noir.

Semaphore V4
Semaphore is a protocol enabling individuals to prove group membership and send messages (such as votes or endorsements) anonymously. The latest version enhances efficiency and simplifies the use of libraries and contracts. This presentation will cover the new features, project vision, and the importance and challanges of zero-knowledge technologies.

The Blind Man's Elephant: a product vision towards private identities
A short talk introducing the concepts of key properties we want to achieve in private ZK identities. Sparkling concepts like SSI and DIDs and why blockchains are the best way to ensure that. Finally it concludes with simple ZK and data-structure constructions and different alternatives that are seeking to provide this characteristics. In short, this is a lightning overview of the space, it's desired features and different approaches to achieve them.

Programmable Cryptography and the future of the Internet
You rarely hear of issues at the networking layer of the Internet: networking companies are running utilities business: they are fungible and can be swapped if distrusted. Most of the value captured on the Internet -- and also most abuse -- happen at the Compute and Data layer of the Web. Ethereum gave us a glimpse of a fundamentally different architecture for Compute and Data than Client/Server architecture.We think the Internet is 1/3 complete, and that programmable cryptography can finish it.

Introduction to Multilateral Trade Credit Set-off in MPC
Multilateral Trade Credit Set-off is a process for collecting outstanding invoices from a network of firms and detecting cycles. A cycle is a circular pattern of due payments that connects businesses. Removing a cycle yields liquidity savings for the firms involved. This process is done by a central agency that collects the invoices and performs the netting. Instead, we leverage MPC to perform the set-ff while preserving the privacy of sensitive financial data of the firms

How to do something to some state in some contract
Smart contracts are changing. So far, they needed every transaction to be public in order for nodes to agree. Zero-Knowledge came in to change things a bit: you can actually make your transaction client-side and just broadcast a proof. In this workshop, we will use Noir and write a simple Aztec and/or Ethereum contract that allows for most of the execution and state to remain private.
