What is Indexed Blockchain Data?

Indexed blockchain data is a form of organized, structured, and formatted on-chain data processed out of the raw data stored across any blockchain protocol, be it public L1, L2, appchains, or rollups. A data indexer is a tool that crawls and indexes blockchain data, aiming to streamline data accessibility and searchability for all kinds of applications and data consumers. As we know, the blockchain contains vast amounts of data, and its database continues to expand with the addition of newer blocks.
