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.

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 (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, 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) 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.

This week, Jorrin Bruns (Support Engineer, Parity Technologies) is joined by OriginTrail’s Tomaž Levak (co-founder) and Žiga Drev (co-founder). OriginTrail is a Substrate-based blockchain that recently won a parachain slot on Polkadot. OriginTrail developed the world’s first Decentralized Knowledge Graph (DKG) to organize humanity’s most important assets, making them discoverable, verifiable, and valuable, often referred to as 'the google of Web3'.

This talk explores the real-world use cases of OriginTrail, and how through the synergy of knowledge graphs and blockchains, DKG forms the "semantic layer of Web3", enabling Web3 builders to organize, discover, and verify anything. It’s similar to the technology used by major Web2 giants like Google and Amazon to power their services.

The OriginTrail team explain how they moved into Web3 and achieved mainstream adoption, starting out on Ethereum as one of the first and most promising blockchain projects to address supply chain use cases, and evolving into a multichain decentralized knowledge network. They also discuss the OriginTrail parachain, enhancing the DKG with Substrate, unleashing network effects through Polkadot, collaborating with parachains, and how you can participate in OriginTrail, from running nodes to interacting with the community.

This week Jorrin Bruns (Support Engineer, Parity Technologies) is joined by Cassidy Daly, token design and research specialist at Centrifuge, a Substrate-based blockchain that recently won a parachain slot on Polkadot. Centrifuge aims to bring an archaic financial system into the Web3 space, enabling users to unlock financing for their real world assets by bringing them on-chain.

Daly describes why the team chose Substrate to build Centrifuge and its canary network Altair, and why Centrifuge became a Polkadot parachain: to reconcile issues with Ethereum including scalability and fees, and the difficulty in maintaining an ETH bridge. They also discuss bringing the Tinlake DApp from Ethereum over to Centrifuge to tap into the specialization between interoperable parachains and drive efficiencies, lower the cost of financing and guarantee the custody and ownership of physical assets on-chain.

This week, Joe Petrowski (Technical Integrations Lead, Web3 Foundation) is joined by Jamie Burke, CEO, and founder of Outlier Ventures, an accelerator that supports the development and growth of emerging technologies, including Polkadot. They are currently running a Polkadot accelerator through their Base Camp program.

Burke describes what he set out to achieve by founding Outlier Ventures in the context of the current internet where platforms are vulnerable to state capture and coercion and are biased against users. With these flaws in mind, the pair discuss the optimal Web3 tech stack with ‘sovereignty first’ as a core design principle and building a permissionless financial system in the context of the Metaverse.

The conversation moves on to the Metaverse as a framework for the direction of Web3 where value and identity are transferred and owned by the user. They discuss how to navigate this realm in terms of technology, finance, and culture, and how this aggregate economy would enable a more open metaverse across lots of different use cases, from music to gaming, the creator economy, and more.

In this episode, Jorrin Bruns (Support Engineer, Parity Technologies) is joined by Robonomics Software Architect Sergei Lonshakov. Robonomics is an open-source internet of things (IoT) platform. It provides ways for humans to communicate with robots, and for robots to connect to each other and the internet. Started on Ethereum in 2015, Robonomics is now aiming to be a parachain on Polkadot, with a view to work across both ecosystems. The team also publishes scientific research on the frontier between IoT, blockchain, Ethereum, Substrate, and Polkadot.

The pair discuss real use cases of robotics, from those currently available, e.g., in smart cities, to futuristic possibilities in the Fourth Industrial Revolution. Along the way they talk about Mars colonization, digital twins and robot art. Lonshakov also presents Robonomics Web Services (RWS) and the development of the Robot Operating System (ROS), a framework of ready-to-work packages that enable engineers without blockchain experience to create robotic systems that connect to blockchain.

This week the tables are turned on Relay Chain, with Jorrin Bruns (Support Engineer, Parity Technologies) interviewing co-host Joe Petrowski (Technical Integrations Lead, Web3 Foundation) as a guest representing his contribution to the Statemint/Statemine project. Statemine — Kusama’s version of Polkadot’s Statemint — is a common-good parachain for creating and managing assets and NFTs on-chain. It recently made history as the first live, featureful parachain to be onboarded to Kusama. Now that Statemine has been made permissionless, anyone can use it to create and deploy tokens and NFTs.

The pair discuss computational resources, achieving faster speeds, lower transaction fees and the potential to shell out those fees for assets, while incentivizing validators. Petrowski also shares his insights into conceiving and deploying a parachain within two months, the Substrate build, and the project’s challenges from upgrading a runtime without governance to asynchronous asset management across chains, and what’s next for the project.
