Relay Chain is a podcast covering blockchain development and building the decentralized web. We focus on the cutting edge of blockchain tech, including Substrate (https://parity.io/substrate) and Polkadot (https://polkadot.network). Brought to you by Parity Technologies (https://parity.io), a core blockchain infrastructure company. Parity is creating an open-source creative commons that will enable people to create better institutions through technology. Follow us at @paritytech (https://twitter.com/paritytech) and @relaychain (https://twitter.com/relaychain). To be informed of new episodes, subscribe to the podcast and our newsletter (https://parity.io/newsletter).
This week, Jorrin Bruns (Support Engineer, Parity Technologies) is joined by Chrissy Hill, General Counsel, and Alica Schiffhauer, Legal Operations Specialist, from Parity’s legal team. This episode focuses on the legal side of Web3 and all that it entails, including the challenges of working within compliance for a codebase with no existing legal precedent.
They discuss the unique aspects of working within Web3 law, such as needing a working knowledge of complex technology, blockchain-specific terminology, staying on top of evolving blockchain regulation, as well as their recommendation to become familiar with the legal side of the blockchain space. In addition, you'll learn how legal teams support Web3, by bridging the gap between national laws (to avoid what happened with FTX, for example), identifying and mitigating risks, and how accountability works for breaches of the law within a decentralized system.

Polkadot Common Good Parachains Update: Blockchains to Benefit the Polkadot Community
In this episode, host Jorrin Bruns (Support Engineer, Parity Technologies) is joined by Joe Petrowski (Common Good Parachains Team Lead, Web3 Foundation) to talk about common good parachains (https://polkadot.network/blog/common-good-parachains-an-introduction-to-governance-allocated-parachain-slots/) (aka system level parachains), the layer-1 Polkadot blockchains dedicated to core functionality that benefits the entire Polkadot ecosystem. Since Statemint, dedicated to asset and NFT functionality, launched as Polkadot’s first common good parachain (https://polkadot.network/blog/statemint-becomes-first-common-good-parachain-on-polkadot/), many more have been in development. This episode explores how common good chains are evolving and what this means for the Polkadot ecosystem, from the new Collectives parachain, evolving NFTs on Statemint, to the upcoming Bridge Hub parachain, and many exciting projects coming out of the ecosystem.
During this talk, Petrowski describes how common good parachains are elected, categorized, onboarded, and eventually made available to users. He highlights the importance of the Cross-Consensus Message Format (XCM) (https://polkadot.network/blog/xcm-the-cross-consensus-message-format/) for system-level parachains, and those which are ready to launch once XCMv3 is deployed. Finally, during the analysis of parachain transaction validation and finalization, we discover the eye-opening benefits of moving core functionality off the relay chain; Polkadot could support far more than 100 parachains, with far fewer than 1,000 validators needed to process transactions with the same security guarantees as before.

Composable Finance Part 2: Envisioning the Valhalla of Cross-Chain DeFi
This week we have the second half of the conversation between Jorrin Bruns (Support Engineer, Parity Technologies) and 0xbrainjar, founder and CEO of the Polkadot parachain Composable Finance. Composable and sister parachain Picasso on Kusama allow smart contracts built on different languages and different chains to connect, enabling cross-chain DeFi applications and more.
If you missed part 1, have a listen here (https://relaychain.fm/44-composable-finance-part-1-unlocking-cross-chain-cross-layer-defi-on-polkadot).
In part 2, they talk more about Mosaic, Composable’s transfer availability layer, and XCVM, their cross-consensus virtual machine. They look at how Composable approaches cross-chain bridging and communication, interoperability with ecosystems outside of Polkadot, and thinking outside the box for cross-chain applications beyond what’s already been done before.
