Accessing blockchain data for practical Web3 development, the SubQuery story :: with James Bayly

In this episode of Ventures, my guest James Bayly (https://twitter.com/jamesabayly) and I discuss SubQuery (https://subquery.network), including information that Web3 developers need to know about how to practically access data from blockchains to engineer decentralized applications. We talk about the various APIs available, where SubQuery fits in the Web3 data availability landscape, the difference between indexers and RPC nodes, SubQuery’s financial model, and what excites James about the Web3 space in general.
