Episode 133: Trusted Setup Ceremonies Explored

In this week's episode, Anna explores the state of trusted setups with 4 of the people who have recently coordinated and run trusted setups for different SNARK systems. She interviews Koh Wei Jie from the Ethereum Foundation, Thomas Walton-Pocock from Aztec Protocol, Brecht Devos from Loopring and Kobi Gurkan from the EF and cLabs. This episode covers the new generation of trusted setups and how the teams working on these are learning from each other and at times, even sharing parts of the trusted set up itself.

As a primer, Trusted Setups are those events or ceremonies that one needs to perform to generate the parameters that can kick off SNARK based systems. It is an MPC – or multiparty computation – that involves a number of participants sequentially downloading software, running a computation that includes some randomness that they generate and re-uploading their result to be folded into the next participants computation. At the end of this process, there is a hidden parameter that is used to create the keys that are used to create proofs for private transactions, and to verify those proofs. These keys prove that a transaction is correct.

Here are some helpful links about all the various trusted setups we mention:

Episode 202: Stateless Ethereum & Verkle Tries with Dankrad Feist

This week, Anna speaks with Dankrad Feist, a researcher at the Ethereum Foundation. They talk about the future of the ETH client infrastructure, the Merge, Verkle Tries, and more. They also explore how concepts that originated in the ZK research space have made their way into the ETH client stack.

Episode 201: DeFi’s Multichain Future with Zaki Manian from Sommelier

This week, Anna catches up with Zaki Manian and his new project Sommelier. They explore how Sommelier aims to develop strategies to better serve the more complex emerging DeFi projects like Uniswap V3, and how this would allow the average user to benefit from these new powerful tools. They also discuss Zaki’s vision for multichain DeFi and how the space has evolved over the last few years.

Episode 200: SNARK Research & Pedagogy with Alessandro Chiesa

This week, in our 200th episode (!), Anna chats with Alessandro Chiesa, a professor working on cryptography, complexity and security. Anna and Ale dig into some of the recent SNARK research coming out of his lab and discuss how to navigate the challenges of teaching in a space that changes quickly.

Episode 199: Snapps on Mina with Emre and Izaak

In this week’s episode, Anna chats with Emre Tekişalp and Izaak Meckler about what’s new with Mina, O(1) Labs, the network launch and the anticipated release of Snapps to testnet later this year. We learn more about how Snapps – these SNARK-powered applications are the bridge between real world data that can be represented cryptographically – think https for the blockchain.

Episode 197: WalletConnect & the DApp/Wallet connection with Pedro Gomes

This week, Anna chats with Pedro Gomes, Founder of WalletConnect, about how wallets and DApps traditionally interact and the journey to WalletConnect and WalletConnect 2.0. Pedro shares the ideas behind the new WalletConnect 2.0 development and his thoughts on what role the project will play in a Multi-Chain future.

Episode 196: Mixnets, Activism and Privacy with Nym’s Harry Halpin

This week, Anna chats with Harry Halpin, CEO of the Nym project, about a variety of topics related to privacy, politics and the need to build censorship-resistant systems. Harry talks about his early involvement in cryptography and his changing perspectives on capitalism as a tool for good. He shares how Nym aims to protect blockchain transactions from network-based deanonymization attacks.
