The Bitcoin Data Analysis Challenge
Bitcoin, the pioneer of decentralized digital currencies, has generated complex transactional data since its 2009 inception. While blockchain technology theoretically provides transparent records, extracting meaningful insights from raw data resembles finding needles in a digital haystack due to:
- Structural Complexity: Transactions form directed weighted hypergraphs with multiple inputs/outputs
- Data Limitations: Existing datasets either lack network transformation or cover insufficient transactions
- Tool Obsolescence: Key software like BlockSci became unsupported after 2020
