Episode 147: Oasis Labs & Privacy with Vishwanath Raman

In this episode, we catch up with Vishwanath Raman, Privacy Architect at Oasis Labs where he works on privacy and confidentiality technologies for Direct to Consumer and Business to Business use cases. His interest and experience span formal methods, applied machine learning, security, and privacy. Vishwa got his PhD in Computer Science at UC Santa Cruz followed by postdoctoral work at Carnegie Mellon.

The Oasis Network is a privacy-enabled blockchain platform for responsible data use. Using a combination of secure computing and privacy technologies, the Oasis Network enables data owners to take control of their data and treat their data as a digital asset via data tokenization. They provide privacy as a service and use secure enclaves and differential privacy in order build a platform for a responsible data economy.

We dive into the way the Oasis system is architected for privacy, who the ideal customers are and what the use cases for this protocol is. We also chatted about some of the tradeoffs in using SGX as well as the recent Binance-led CryptoSafe Alliance announcement where Oasis is the primary infrastructure builder.

Here are some of the papers and links that we discuss:
Oasis Labs at zkSummit ZK0x02
Chorus: Differential Privacy via Query Rewriting
Towards Practical Differential Privacy for SQL Queries
Problems with machine learning and privacy (one of many)
Towards Practical Differentially Private Convex Optimization

One small correction: Vishwa mentions the number of Validators on Oasis as numbering in the hundreds, but upon checking, we were informed that the number of validators that will participate in the consensus committee at mainnet launch is 70-100.

Thank you to this week’s sponsor Trail of Bits.

Trail of Bits has recently published a new guide for building secure contracts with their Crytic offering.

Crytic is a SaaS-based GitHub application created by Trail of Bits that continuously assures your Ethereum smart contracts are safe and functional. It reports build status on every commit and runs a suite of security analyses so you get immediate security feedback.

Check out this guide for tips on how to build security into your dapps from the start and how to use the Trail of Bits suite of tools for automated vulnerability detection.

Thank you once again Trail of Bits

Episode 320: A Deep Dive into Shared Sequencers with Espresso’s Ben Fisch

In this week’s episode, Anna (https://twitter.com/annarrose) and Brendan Farmer (https://twitter.com/_bfarmer) catch up with Ben Fisch (https://twitter.com/benafisch), CEO of Espresso Systems (https://www.espressosys.com/). They explore the inner workings of the current L2 sequencing landscape and then discuss how a shared sequencing marketplace like Espresso works. They touch on how MEV plays a part in the new system, how the role of the sequencer can be separated into subroles, how all these parts will work together in such a system and much more.

Episode 319: The Past & Present of the L2 Landscape with Jordi Baylina

In this week’s episode, Anna catches up with Jordi Baylina, OG Ethereum contributor and Polygon zkEVM Technical Lead. They cover what Jordi has been working on since he was last on the show in 2021. Back then, zkEVMs were still just an idea. Now that many of these systems have launched, they have a chance to look at how these fit into the general L2 landscape.

They cover Jordi’s view on engineering decentralized systems and how these are rolled out, and the recent research from Polygon, including their AggLayer proposal. They wrap up on what inspires him to keep contributing in the space.

Episode 318: Threshold Signature Schemes & FROST with Chelsea Komlo

In this week’s episode, Anna and Nico chat with Chelsea Komlo, Chief Scientist for the Zcash Foundation and member of the Cryptography, Security, and Privacy lab at the University of Waterloo.

They discuss what sparked Chelsea’s interest in cryptography research, starting with her work contributing to Tor, to her move to Zcash and her PhD work on Threshold Signature Schemes. They define some important terms around different signature schemes and discuss possible optimizations that can be used to make these more performant. They then dive into her work on the FROST Threshold Signature Scheme plus some new upcoming work.

Episode 317: Enhancing On-Chain Intelligence with Ritual

This week, Anna and Tarun chat with Niraj Pant and Anish Agnihotri from Ritual. They kick off by revisiting the AIxCrypto intersection before diving into the Ritual product and its goals around developing open access AI infrastructure. They explore the opportunities that open up when you bring ML to smart contracts.

Bonus: zkSummit11 reminder!

Quick reminder about our upcoming zkSummit 11 event. Happening in Athens on April 10th, we once again bring together the top researchers and engineers working in zk to share their latest research and new findings.

Episode 316: Alin Tomescu on Distributed On-chain Randomness and Keyless Accounts

In this week’s episode, Anna and Nico chat with Alin Tomescu, founding team member and Head of Cryptography at Aptos Labs. They discuss Alin’s journey to Aptos and his work on distributed on-chain randomness as well as the new Aptos Keyless project. They cover the Keyless accounts architecture, how the flow works for the user and some of the subtleties in the approach they have taken.

Episode 315: ZK Hack Ecosystem & Winners of ZK Hack IV

This week’s episode is a little different from the usual and is split into two parts with Anna and Kobi exploring the history of ZK Hack, its origins and how the event has evolved into what it is today, including current activity in the ZK Hack ecosystem. The second half of the show splits off into Anna and Nico chatting the top 3 hackers from ZK Hack IV Online, which wrapped back in February. Each mini interview catches up with one of the winners and dives into what it was like to hack on the puzzles, which their favourites were and how they can be improved in the future.
