substrate-etl is a large scale index of Polkadot + Kusama and their parachains based on Polkaholic.io, a multichain block explorer/indexer. Using this data warehouse, anyone can query decoded blocks, extrinsics, events, calls across both ecosystems.
We onboarded Polkadot Data into Google Public Datasets, announced in September 2023:
The substrate-etl index results in two large datasets (crypto_polkadot and crypto_kusama) covering the 2 relay chains and over 70 parachains. This represents Polkadot/Kusama alongside other Web3 ecosystems and supports complex large scale analyses with SQL using BigQuery's lightning-fast query performance on extremely large datasets. Having substrate-etl enables Dune-like analytics to guide business intelligence, inform engineering decision making, and showcase ecosystem growth.
Power users include Parity Data (led by Karim Jedda and Pavla Mijic), Subwallet/DotInsights, Web3metrics,
Dolpha.com, ChainViz and many data analysts within parachains and outside the ecosystem.
