What can we learn from the failures of Web2 idealism? How do we build systems that continue to reflect Web3 ideals as business models scale into the future?

In this episode, Joe Petrowski (Research Analyst, Parity) talks with Shira Frank, co-founder of Maiden, the first global user research lab dedicated to forging a path to mainstream blockchain adoption. They explore the importance of building Web3 systems with proper research into possible downstream risks so as to create true change and offset imbalances of wealth, power, information, and agency.

What are the challenges in integrating off-chain data into blockchain smart contracts with oracle systems, and how might secure, oracle-powered DeFi create meaningful social impact?

In this episode, Joe Petrowski (Research Analyst, Parity) talks with Sergey Nazarov from Chainlink, a decentralized oracle system bringing external, real-world data to blockchain-based smart contracts. Oracle systems like Chainlink are a necessary part of decentralized finance (DeFi), for which off-chain data such as market prices are used to trigger smart contract functions. We discuss the inherent challenges in integrating off-chain data with end-to-end security guarantees, the barriers to building smart contracts that go beyond tokenization, Chainlink use cases, the promise of blockchain for social impact, and how Chainlink is planning a Polkadot integration.

In this episode, hosts Joe Petrowski (Research Analyst, Parity) and Phil Lucsok (Product Communications Manager, Parity) speak with Wei Tang (Core Developer, Parity) about his work on several Ethereum- and Substrate-related projects. They discuss Tang’s experience working on Ethereum, Ethereum Classic, and Substrate, including innovative proposals for account versioning, backwards compatibility, and bridging and merging different Ethereum chains, as well as the future of ETH 2.0 and the broader Ethereum community.

Tang is known among his peers as an exceptionally gifted and prolific developer, having built the SputnikVM Rust implementation of Ethereum from scratch just by reading the Ethereum yellow paper (without looking at other clients), and having created the Substrate EVM implementation in just a few days.

What are the benefits of tokenizing regulated assets, and how might it revolutionize the world of finance?

In this episode, Joe Petrowski (Research, Parity) is joined by Adam Dossa, Head of Blockchain at Polymath, a security token platform currently building a custom blockchain on Substrate called Polymesh. They discuss the world of tokenized securities and the promise this area of decentralized finance holds for democratizing global wealth creation. Dossa also explains Polymath’s reasoning for moving from Ethereum to the Substrate blockchain building framework.
