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.
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.
How To Hallucinate A Server
A Hallucinated Server is a virtual server whose execution is cryptographically simulated by users, using "multiplayer" privacy technologies like multi-party computation or fully homomorphic encryption. Today, thanks to recent advancements in MPC and FHE, we have the technology to build the first fully Turing-complete hallucinated servers. We discuss the underlying technologies, and how we've used them to build several proof-of-concept applications.

Little Things We've learned About FHE
Recently, at PSE, we have been exploring the field of cryptography, specifically focusing on Fully Homomorphic Encryption (FHE). FHE enables secure interactions with encrypted data between different parties. In this presentation, we will introduce key concepts and essential information tailored for developers and application designers. This will help them quickly grasp the fundamentals without getting bogged down by complex mathematical details.
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.
TLSNotary: Applying MPC and interactive ZK to prove web2 data
Diving into TLSNotary, a protocol which leverages multi-party computation and interactive ZK to prove the authenticity and provenance of any data on the web to another party. Summary: 1. What it is and what it can do 2. High-level overview of how it works 3. Details on the underlying MPC and ZK protocols that we use 4. How to use 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
Elliptic curves and SNARKs: past, present and future.
Elliptic curves are used in many proof systems. Some systems (e.g. Bulletproofs) use plain curves (e.g. ed25519). Some (e.g. Groth16, KZG-PLONK) use pairing-friendly curves (e.g. BLS12-381). Some recursive systems require pairing-friendly 2-cycle (e.g. MNT4/6) or 2-chains (e.g. BLS12-377/BW6-761). Some other recursive/folding systems require plain 2-cycle (e.g. Pasta). In this talk we will go through the difference between these curves and why there isn't a silver bullet curve for all scenarios.
Efficient non-native SNARK recursion using bivariate polynomial testing
Efficient SNARK recursion requires switching between pairing friendly elliptic curves. In most optimal approaches these curves would construct a cycle, but there are no such known cycles. Instead, we use non-native arithmetic to brute force the pairing computation at the cycle cut-off. We describe an approach for combining direct field extension with polynomial-based non-native arithmetic. This reduces pairing computation to bivariate polynomial identity testing using Schwartz-Zippel lemma.
