Users can now access Ethereum blockchain data directly through Google's BigQuery data warehouse service. The Ethereum public dataset contains all historical records in the ethereum_blockchain dataset, which Google updates daily. Additionally, Google has open-sourced the Ethereum ETL project on GitHub, providing all code used to extract blockchain data and load it into BigQuery.
Challenges in Blockchain Data Analysis
While Ethereum's peer-to-peer software offers API endpoints for basic functions like:
- Checking transaction status
- Querying wallet transactions
- Verifying wallet balances
these endpoints don't provide comprehensive access to all blockchain data, making aggregated analysis nearly impossible through standard APIs.
The Value of Blockchain Analytics
Analyzing complete blockchain datasets enables powerful applications, particularly when visualizing:
✅ Daily ETH transfer volumes
✅ Average transaction costs
👉 Discover how blockchain analytics transform business decisions
Google emphasizes that such visualizations aid critical business choices—like determining whether to upgrade Ethereum infrastructure to balance financial sheets. Organizations can identify when systems approach capacity limits to make informed upgrade decisions.
Technical Implementation
Ethereum's architecture resembles Bitcoin's—both function as immutable transaction records (OLTP databases) but lack native OLAP capabilities. BigQuery fills this gap with robust OLAP functionality, eliminating the need for additional API implementations in most use cases.
Google's cloud-based solution:
- Synchronizes the Ethereum blockchain with Parity wallets on Google Cloud
Extracts daily data from the distributed ledger including:
- Currency transfers
- Smart contract execution results
- Denormalizes and groups data by date
- Stores processed data in BigQuery for analysis
Practical Analysis Examples
1. Transaction Volume and Network Analysis
Ethereum hosts numerous currency types with distribution patterns that vary by type and time. Analyzing transaction activity reveals which currencies gain popularity during specific periods.
A query measuring aggregated currency statistics identified the top 10 most active Ethereum tokens, with OmiseGO ranking fifth. Daily transaction analysis showed a significant spike in OmiseGO receivers on September 13, 2017—coinciding with the OmiseGO Token Airdrop launch—without matching growth in senders.
2. Directed Graph Visualization
High-precision wallet transfer data enables analysis via directed graphs. Google visualized datasets containing:
- Nodes representing wallet addresses
- Edges indicating aggregated currency transfers between addresses
Edge lengths proportionally represent transfer volumes: wallets exchanging more currency appear closer together in the visualization.
