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. They discuss why these innovations matter, what the new paradigms enable within the Ethereum ecosystem, their goal to provide privacy and scalability for blockchains, their recent acquisition by Polygon and more.

Today’s episode is sponsored by Aleo.

Aleo is a new Layer-1 blockchain that uses cutting edge cryptography to achieve the programmability of Ethereum, the privacy of Zcash, and the scalability of a rollup. It gives developers the tools they need to build programs that protect privacy while allowing applications to be regulatory-compliant. It also features a new domain-specific programming language called Leo that enables non-cryptographers to harness the power of ZKPs to build private applications like decentralized exchanges, hidden information games, regulated stablecoins, and more.

Go to aleo.org to learn more about the protocol, or roll up your sleeves and visit leo-lang.org to start building.
