Querying the World's Data with SubQuery

Jorrin Bruns (Support Engineer, Parity Technologies) talks with James Bayly, Head of Business Development for OnFinality, one of the largest infrastructure providers for Polkadot and Substrate, about Subquery, a tool that speeds up querying and extracting Polkadot network data so that anyone can take the data off-chain and create something useful. They discuss the team's mission to deliver high performance, decentralized services to distribute assets at scale, integrate with blockchain oracles and build tools and infrastructure to advance the Polkadot ecosystem. Bayly provides insights into SubQuery’s network participants, how collaboration and feedback from Polkadot projects in New Zealand influenced several of its value-added features, their long-term plans to become a parachain and the road to 1 billion API (application programming interface) requests.
