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.
