Navigating over a million data tables on Dune might seem daunting. This guide simplifies the process, highlighting the categories of datasets available and offering tips on efficient searching.

Categories of Datasets

Dune processes blockchain data in several stages: ingestion, decoding, aggregation, and standardization. This results in three main categories: raw, decoded, and curated. Additionally, there’s a community category that houses community-supported off-chain datasets like Reservoir, Snapshot, and others.

Beyond these, Dune showcases the most frequently used datasets under the “essential” category. Your materialized query results are neatly categorized under “materialized views”.
