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.
Leveraging High-Performance Computing for Efficient STARK Provers
Zero-Knowledge Proof (ZKP) protocols' applicability hinges on the prover's ability to efficiently generate proofs. This talk explores the computational aspects affecting ZKP performance, specifically focusing on STARK provers. We will analyze performance across high-performance and standard computing architectures and interpret results by examining key workload characteristics. From this understanding, we can project ZKP capabilities in future scenarios.
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
The Supreme Ruler of the World
VK rules the world. ZK rules the world, too, like a straightedge wielded with eyes closed. Rulers rule in simple ways: by lining things up and by checking they're all in line. Bring your high school math to learn straightedges called SumCheck and SumCalc and begin to appreciate ZK in simple geometric terms. No moon math. We'll visit lines, cubes and polynomials, to see how they can be used to deduce and to generate, to check and to delegate.
Behind Zupass: Applied Cryptography For Consumers
Recent advancements in cryptography on consumer devices (like your mobile phone) and progress in developer tooling (Semaphore, SnarkJS) have led to the emergence of open-source projects such as Zupass, a personal "cryptographic computer" helping power Devcon. This talk dives into the technical challenges behind scaling ZKPs to 10,000+ consumer devices and the history behind the project, from its inception at Zuzalu to its usage at recent Ethereum events (Devconnect, ProgCrypto, ETHBerlin).
Scalable multi-party FHE with Phantom-zone
The talk introduces "phantom-zone", a framework to write scalable consumer facing MPC apps using multi-party FHE. Starting with what's multi-party FHE, talk gives a demo of non-trivial MPC app. Followed by introduction to programming model of MPC apps using multi-party FHE inside phantom-zone. Then the talk dives deep into primitives to realise multi-party FHE and ends with advanced FHE gadgets that further enhance multi-party FHE.
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.
Circle STARK GPU Acceleration: An Analysis of Performance and Implementation
The session will cover the overview of GPU acceleration for ZK-SNARK/STARK proof systems, focusing on the GPU implementation of Circle STARK. It will address challenges and solutions in implementation, delving into parallelizing computations in provers. We'll compare CPU and GPU performance. Finally, we'll explore future directions for hardware acceleration (ie. FPGA).
An introduction to post quantum signature schemes for Ethereum
In this lightning talk, we will give attendees the opportunity to understand the various post-quantum signature schemes proposed to make Ethereum post-quantum ready.
