Relay Chain

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 (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.

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, 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.

Privacy takes center stage in this week’s episode as Jorrin Bruns (Support Engineer, Parity Technologies) talks with Marvin Tong, co-founder and CEO of the Phala Network, a trustless, privacy-preserving cloud computing network based on Substrate. They dive deep into Phala’s tech, exploring how Phala tackles the issue of trust in the computational cloud by shielding user data from centralized organizations like Google, with the same level of computational power as existing cloud services. Tong details several topics, including node security, Phala’s Substrate-based runtime and bespoke pallets, integrating alternative trusted execution environment (TEE) hardware, and how it tackles consensus. They delve into on-chain data privacy, deploying private smart contract computation for decentralized applications (DApps) and decentralized finance (DeFi) and services on Phala Network including Web3 Analytics and cross-chain interoperability.

WebAssembly is the type we chose. We want to put WebAssembly inside of TEE so that we can support this kind of security technique grade. We think it will be a major choice for not only Polkadot but the whole industry for Web3.” “Using Web3 Analytics, all of the analysis code is running as a confidential smart contract. This means that the data is not deployed by a centralized server like Google or any other big platform. Using Google Analytics means that you trust to put your user’s data node to Google so that they can analyze it for you. From this perspective, on Web3 Analytics, the data is not trusted by any centralized server or centralized gatekeeper, it is just encrypted by Phala’s system, and how to encrypt it is in the visitor or users hands.” “We believe that in the next three years, or five years, the major technology of all computation cloud will be confidential computing cloud. That’s what we can see from what Google, Amazon, and Facebook are doing.” Special Guest: Marvin Tong.

This week Jorrin Bruns (Support Engineer, Parity Technologies) speaks with Sota Watanabe, CEO of Stake Technologies and founder of Plasm, a platform designed to help developers deploy fast and secure decentralized applications (DApps) on Polkadot. They discuss advancing Web3 via cross-chain collaboration, supporting DApp development, and decentralizing the Plasm network. Watanabe walks us through being the first parachain on Rococo, completing the first cross-chain message (together with Acala), bringing Ethereum compatibility and ZK-Rollups to Polkadot, staking and trading DApps, securing a parachain slot, and much more.

Polkadot itself is a scaling solution, but this is a layer 1 scalability solution. We need vertical scalability which is layer 1, that is why we are working on ZKRollups now. Vertical scalability is much faster, more flexible, and cheaper since layer 2 doesn’t need to be a broken chain” “What makes Plasm different from other parachains? We innovated two things, one is DApps staking and another one is the scaling solution ZKRollups” “We are working on an Ethereum bridge, a Secret Network bridge, and also a Binance bridge in the near future” “We have already connected our Plasm network testnet to Rococo and we have deployed a Web Assembly smart contract and it works on the top of Polkadot’s parachain testnet” “In the past few months, we have successfully completed the first cross-chain messaging passing with Acala. Our token can be transferred to Acala and you can receive the Acala token on the Plasm network” “We support Ethereum Virtual Machine on the top of the Polkadot parachain, so the user can actually develop and make applications on top of Polkadot parachain, instead of individual substrate chains. I think this is one of the most important upgrades in the ecosystem” “On the top of the Plasm network, we can transfer ownership of a smart contract” “We are making a new M&A solution in the blockchain system” Special Guest: Sota Watanabe.

This week we dive into Tether, a stablecoin playing an important role in disrupting the legacy financial system, recently announced to be launching on Polkadot. Joe Petrowski, (Technical Integrations Lead, Web3 Foundation) speaks with Paolo Ardoino, CTO of Bitfinex and Tether. They discuss stablecoin trends, regulation and compliance with central banks, CBDCs (Central Bank Digital Currencies), the likelihood of central banks running on public blockchains such as Polkadot and Ethereum, achieving blockchain interoperability through common goods, and the upcoming launch of Tether on Polkadot. Highlights: 00:39 - Intro to Ardoino and Tether 06:38 - The issue of crypto arbitrage 08:57 - Stability by matching a dollar to the pace of Bitcoin 11:01 - Boom and innovation in the stablecoin sector 12:20 - The risks of decentralized stablecoins 13:30 - Achieving purchasing power stability 14:49 - The scope for non-US stablecoins 16:15 - Tether Gold, the precious-metal-backed stablecoin 20:34 - Individual assets vs. a managed basket of currencies 22:48 - Regulation and scrutiny from central banks 27:35 - Blockchain for central banks 28:40 - Tether’s criteria to deploy on a blockchain 30:15 - Common goods for blockchain interoperability 35:07 - Resilience through multiple blockchain support 36:49 - Tether to launch on Polkadot and Kusama Links: Paolo Ardoino on Twitter (https://twitter.com/paoloardoino) Tether on Twitter (https://twitter.com/Tether_to) Grenache (https://github.com/bitfinexcom/grenache) Ampleforth website (https://www.ampleforth.org/) Ardoino’s reading list: Eric S. Raymond, The Cathedral and the Bazaar Key Quotes: “I believe that you can not really understand as a CTO, all the nuances and complexities of your platform, if you stop coding” “the reason why our team decided to create Tether was to solve one problem I’m sure you are familiar with, that is crypto Arbitrage” “Why don’t we create a dollar that moves at the same pace as Bitcoin” “I would stay pure and not allow centralized stablecoins…. Crypto backed stablecoins are a very good value add to the sector, but I would prefer or would have preferred to not have decentralized stablecoins and centralized stablecoins.” “If you are using technology and the banking network, you have to respect the same standards, there is no other way around. That is why Tether has the function to freeze funds in order to cooperate with law enforcement. We do it quite openly, and we communicate when we do. Also, we did that to help many projects. There was an exchange hacked six months ago and we helped them to freeze thirty million dollars worth of Tether. There were many DEFI projects that were hacked and we worked with law enforcement to freeze those funds. That is what is happening in the banking world if someone steals funds from your bank account, the bank has the right to freeze your funds if you have stolen funds. We had to replicate the same functionalities in our centralized stablecoins. That is something that the decentralized coins don’t have and don’t need because they don’t use the banking system, we do, and we have to respect that.” “The idea that central banks will issue directly on Ethereum or Omni or Polkadot is quite realistic.” “You give more freedom to your users, you will gain traction.” “Supporting multiple blockchains makes the entire infrastructure resilient.” Special Guest: Paolo Ardoino.

After a short hiatus, we’re back this week with a new co-host joining the podcast, Jorrin Bruns (Support Engineer, Parity Technologies). In this episode, Jorrin turns the tables and interviews Joe Petrowski (Technical Integrations Lead, Web3 Foundation, and Relay Chain co-host) about the future of the podcast, Joe’s journey from the aerospace industry to professional cycling to Web3, and how blockchain innovation brings together diverse interest groups. They discuss the potential for Polkadot and Web3 to realize a propian future, breaking down surveillance capitalism through decentralized governance, infinitely scalable parachains (so-called hierarchical or nested relay chains), and building a decentralized economy of robots powered by Polkadot.

In this wide-ranging and eye-opening discussion, Joe Petrowski (Research Analyst, Parity Technologies) speaks with Lesley Czuma, Head of Business Development at Equilibrium, a cross-chain money market combining pooled lending with synthetic asset generation and trading. They discuss the massive potential of Web3 and DeFi to radically impact global systems of organization and power, to disrupt monopolies, and bring benefits to those marginalized by the current economic paradigm. They also dive into what Equilibrium is building and the role played by Polkadot and Substrate, the blockchain-building framework from Parity Technologies.

The mainstreaming is going to happen in the same way that it did with the dotcom revolution. You’re going to have blockchain apps becoming so essential that no one is going to be able to ignore them anymore.” Special Guest: Lesley Czuma.
