This week, Jorrin Bruns (Support Engineer, Parity Technologies) is joined by Yubo Ruan, founder of Parallel Finance, a lending solutions provider designed to increase liquidity and acceptance on the Polkadot network. Parallel Finance is a Polkadot parachain and its sister network Heiko Finance is a Kusama parachain. This episode begins with an introduction to Parallel Finance and its tech stack. They also discuss how Substrate helped Parallel launch a parachain in 7 months, and how the project is disrupting DeFi through a unique take on lending design and building user interaction interfaces (necessary for interoperability in DeFi).
