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.
STARK proofs ELI5
Let's face it, ZK proofs are intimidating. But they don't have to be! ZK proofs are complex not because of the depth math they use, but because of the large number of fields of mathematics they leverage features from. In this talk, we'll break down STARK proofs into simple blocks and colorful analogies so that you get a good high level overview of how they work
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
Multiparty Homomorphic Encryption from Ring-Learning-with-Errors
This talk will introduce Ring Learning with Errors (RLWE) based Multiparty Homomorphic Encryption (MHE).
Digital pheromones: MPC for human connection & coordination
Recent MPC research from Cursive and PSE enables a new concept called "digital pheromones": the ability to produce lightweight, privacy-preserving signals that people can use to coordinate safely and efficiently. The primary result we will cover is Trinity, a new 2PC scheme with nearly ideal UX/DevX, built on the trio of PLONK, Garbled Circuits, and KZG Witness Encryption. We will do a live demo with attendees and explore what a future filled with digital pheromones will enable!
End-to-end internet games
For the past 1.5 years, I've been building fully onchain games–games where the entire state is onchain for some reason (have launched 7!). There is lots of cryptographic data floating around the internet. New primitives are allowing all this data to be interoperable with each other... and even verifiable on-chain. I'll discuss some of this tech (tls notary, app attest, zkml, etc.) and discuss what new wild games we can build with them.
