Relay Chain Parity Technologies

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 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.


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.

Jorrin Bruns (Support Engineer, Parity Technologies) is joined this week by 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 swaps and more. By simplifying and unifying DeFi (Decentralized Finance) with new interoperability standards, the project is accelerating this technology into the mainstream.


This talk covers Composable's solutions for developers and end users. 0xbrainjar describes building with Substrate and the new pallets they created, the native functionality of Composable and Picasso, and the various products and DeFi primitives they offer.


Additionally, 0xbrainjar discusses cross-layer NFT transfers, building oracles for price manipulation resistance, achieving protocol-owned liquidity, bootstrapping DeFi and what could be considered ‘DeFi 3.0'.

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.
