The combination of ZKP +/- MPC +/- FHE
This talk will provide you with the necessary intuition to understand when you should use ZKP, MPC or FHE, or any combination of them.

Lightning Talk - Stage 4
MP-FHE experiments. Our learnings trying to find the next big tech to focus on.
This talk mainly focuses on showcasing the work that some PSE members did while starting to dive into MPC-FHE during Q2 2024. This work is composed by various explorations within the MPC-FHE realm that move towards different directions and goals. From FHE compilers to FFT Bootstrapping GPU optimization proposals, passing by FHE Game demos and many application level implementations, the talk aims to reach beginner-advanced audience on the research/product paths that we have explored so far.

Modern ZKP Compilers
At PSE we have done much ZKP advanced development. From that learning we are building a language and compiler, that is summarizing much of this learning. We answer questions like: Are compilers necessary in a zkVM world? What is the role of a compiler in ZKP development? What are its most common components? How different ways can this problem be approached? In this advanced talk, we will learn how we compile arbitrary boolean expressions, or how the Schwartz–Zippel lemma can be used to optimize.

The Blind Man's Elephant: a product vision towards private identities
A short talk introducing the concepts of key principles 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 of ZK, its desired features and different approaches to achieve them.

ZK Email: Fast Proofs and Production-Ready Account Recovery
We discuss progress that ZK Email has made in making new proofs really easy, as well as interesting new on-chain directions for email-triggered transactions. We’ll go over proof registries, email-based multisig signers, and email guardians for account recovery in production.

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!

Utilizing National IDs in the Ethereum Ecosystem
This panel brings together developers of MynaWallet, Anon-Aadhaar, Proof of Passport, and zkPassport, who are exploring and developing applications that utilize government-issued IDs in the Ethereum ecosystem. We will discuss the characteristics of each ID system and what functions can be realized using tech stacks in the Ethereum ecosystem and cryptographic technology.

Panel - Stage 6
Multi-Party FHE for Multi-Player Privacy
Privacy is an unsolved challenge for blockchains and decentralized systems. ZK cryptography gets us there partially, but not all the way. ZK enables 'single-player private state,' and certain other kinds of privacy are impossible to realize with ZKPs alone. Panelists, the cryptography library devs, infrastructure builders, and application devs who have recently started to explore programmable encryption will discuss MP-FHE as one such tool for achieving more general privacy capabilities.

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.
