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:

• Enhancing Google Cloud’s blockchain data offering with 11 new chains in BigQuery
• Polkadot - Harness the power of Polkadot's BigQuery Public Dataset

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.

Roadmap

In addition to continuing support for substrate-etl/Polkaholic.io for existing and future chains, our plans for 2024 are to:

• chart a course within the Decentralized Futures for 2024, supporting Web3 Foundation's Data Analysis Tools for Substrate-based Blockchains (e.g. traces and staking), chart a course for substrate-etl + Polkaholic APIs to support Dune Analytics Style Data Service for Polkadot/Kusama with leading teams in the ecosystem
• develop + support a Polkadot Builder Collective with a "builders supporting builders" orientation
• build support for CoreJam+CorePlay+DA and extend support for ink!/WASM contracts
• extend substrate-etl to support raw + fully-decoded EVM datasets (transactions+logs), enabling Substrate+EVM hybrid chain analytics, as more parachains incorporate hybrid chain designs
