About Devcon —

Devcon is the Ethereum conference for developers, researchers, thinkers, and makers.

An intensive introduction for new Ethereum explorers, a global family reunion for those already a part of our ecosystem, and a source of energy and creativity for all.

MPCStats

Duration: 00:08:28

Speaker: Kevin Chia, Teeramet (Jern) Kunpittaya

Type: Lightning Talk

Expertise: Intermediate

Event: Devcon

Date: Nov 2024

MPCStats is a framework allowing data consumers to query statistical computation from either one or multiple data providers while preserving privacy to those raw data. We support standard statistical operations, including nested and filter ones. Data providers do not leak their data and data consumers can be convinced the computation is done correctly.

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.

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.

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.

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!

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.

MACI - Why do we need private voting and what are we up to

MACI is a protocol that can be used to run private on chain polls. This talk will introduce the protocol, dive into some of the technical aspects. Finally we will talk about the team's plans for the future and how the community can get involved to help improve the project.

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

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.
