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?''
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: 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.
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.
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
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.
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.
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.
