Vulcanize DB is a set of tools that make it easier for developers to write application-specific indexes and caches for distributed apps built on the Ethereum blockchain. Data structures and data encodings that enable Ethereum to be a trustless, distributed virtual machine complicate accessibility and usability of that data for dApp developers. It provides an efficient way to get historical data from the chain by allowing users to extract, transform, persist, and ultimately expose it via a graphQL API.
