Episode 223: Connecting Cosmos and Ethereum with Gravity Bridge

This week, Anna chats with Deborah Simpier and Justin Kilpatrick, co-founders of Althea and the team working on Gravity Bridge. They start with the history of the Althea project and how they aim to build an open marketplace for independent entities to create their own ISPs, providing bandwidth to users in under-connected areas. They then dive into the larger topic of bridges and the work being done on Gravity Bridge – a bridge that links Ethereum with IBC and the Cosmos ecosystem. They touch on the larger bridge landscape in Cosmos, the new initiatives and challenges that come with a multichain architecture, the opportunities and hazards of the current wave of stakedrop airdrops in Cosmos, Gravity’s roadmap and more!

Episode 222: Something Brewing with Jill Gunter and Ben Fisch from Espresso Systems

This week, Anna and Tarun chat with Jill Gunter and Ben Fisch from Espresso Systems. Espresso has been in stealth mode for a couple of months, but recently went public with their Proof of Stake L1, developed with flexible private applications and ZK rollups in mind. They explore the founding and development of the project, the Espresso base chain and the CAPE-wrapped privacy smart contract application that they’ve built. They walk through the programming model, the evolution of privacy technology, what configurable or flexible privacy means and Espresso roadmap up and more.

Episode 221: Funding the Next Wave of Zero Knowledge Tech

This week Anna dives into the state of funding in the ZK space. She chats with a number of different groups who are all funding zero knowledge technology from different angles. She kicks off the conversation with her colleague from ZKValidator Susannah Evans and Gubsheep from 0xPARC about the Gitcoin side round they are leading which is focused on funding the next wave of ZK tech projects. She then chats with Arjun Karlsy, VP of Growth at Polygon about their massive commitment of 1 billion into ZK through investments, acquisitions, and grants. Following this, she catches up with Alex Pruden, CEO at Aleo to talk about their soon to launch grant program – Zprize, an industry-wide effort to accelerate zero knowledge technology. And lastly, she speaks with Alistair Stewart from the Web3 Foundation about a newly announced ZK component of the Polkadot Pioneers Prize.

Episode 220: The Road to Plonky2 with Brendan and Daniel from Polygon Zero

This week, Anna chats with Brendan Farmer and Daniel Lubarov from Polygon Zero, formerly known as Mir, about their early experiments with different proving systems, their work combining PLONK and Halo called Plonky – as well as the more recent combination of PLONK plus FRI (a technique that is borrowed from STARKs) which makes up Plonky2.
