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.
ZKPs and "Programmable Cryptography"
Historically, cryptographic protocols have been built special-purpose for specific kinds of claims or information hiding mechanisms. zkSNARKs and other new cryptographic tools move us to a world of "general-purpose" cryptography, where we have expressive languages to express claims about digital identity, reputation, and more. We discuss a high-level framework for thinking about where and why ZK and related technologies might (or might not) be useful for digital applications.
Programmable Cryptography and Ethereum, Panel
One of the core themes of this panel is how Programmable Cryptography synergizes with Ethereum. Panelists will discuss questions such as ''Why have we not been able to do everything we've wanted with Ethereum?'' and ''Why have certain kinds of applications - from decentralized social to decentralized games to decentralized finance - not been able to reach their full potential with only consensus technology?''
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.
What to know about Zero Knowledge
Zero Knowledge, aka ZK, has become a catch-all term to represent much of "modern" or "advanced" cryptography -- especially cryptography that's relevant to the future of blockchains. In this panel, we will share our perspectives on ZK -- how to think about it, what to look out for, and what to focus in on. We'll also discuss how ZK may alter and complement Ethereum's own future.
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.
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.
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.
MPC Tooling or How to create MPC apps
Let's get into the state of the art of MPC development: we'll discuss different MPC schemes, current MPC tooling & how you can create MPC apps today. We'll cover the tech stack from a frontend level (e.g. MPC compilers) to a backend - and of course how we can combine 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.
