Core Insights - The article discusses blockchain ETF software, which is designed to display, analyze, and manage investments in blockchain-related ETFs, emphasizing that it is traditional financial software rather than decentralized applications built on blockchain technology [1] Functionality Overview - **Real-time or Near Real-time Price Display**: The software shows current market trading prices, daily price changes, and trading volumes by connecting to data providers like Bloomberg or Refinitiv [3] - **Historical Price and Chart Analysis**: It provides historical price data visualized through various chart types, supporting technical analysis tools [4] - **Fund Overview and Strategy Introduction**: The software displays essential information about the ETF, including its name, code, management fees, and investment strategy [5][6] - **Holdings Information View**: It lists the current stocks held by the ETF along with their weight in total assets, including company names and industry classifications [7][8] - **Fund Performance Display**: The software showcases the ETF's returns over different periods and compares them with benchmark indices or similar funds [9][10] - **Latest Net Asset Value (NAV)**: It shows the ETF's NAV calculated after market close, which is crucial for assessing the fund's intrinsic value [11] - **News and Research Reports**: The software integrates news and research reports related to the ETF and its holdings, requiring connections to news APIs [12] - **Risk Alerts and Document Access**: It provides risk warnings and access to official documents like prospectuses and periodic reports [13][14] - **Buy/Sell Entry (Optional)**: While actual trading occurs on brokerage platforms, the software can link to these platforms for user convenience [15][16] Management Features - **Portfolio Management**: The software manages the actual stock holdings, quantities, and costs, often integrating with internal systems of fund managers [19] - **Creation/Redemption Processing**: It handles the creation and redemption of ETF shares, involving complex settlement processes [19] - **Fee Calculation and Distribution**: The software calculates various fees and deducts them from fund assets [19] - **Compliance and Reporting**: It generates reports to meet regulatory requirements and monitors investment restrictions [19] Technical Considerations - **Data Source Integration**: A key challenge is efficiently obtaining data from multiple financial data providers and exchanges [19] - **Backend Architecture**: A robust backend system is necessary for processing real-time data, storing historical data, and managing user data [19] - **Database Design**: High-performance database schemas are required for storing and querying time-series trading data [19] - **Real-time Data Processing**: Technologies like message queues and stream processing are essential for low-latency data transmission [19] - **Frontend Development**: Modern frameworks and high-performance chart libraries are used to build user interfaces [19] - **Security**: Data security, user authentication, and protection against cyber threats are critical for financial software [19] - **Compliance**: The software must adhere to financial regulations in its operating regions [19] - **Blockchain Representation**: The software's uniqueness lies in its focus on investments in blockchain-related companies, providing relevant data and analysis without operating directly on a blockchain [19]

Group 1 - The testing of blockchain ETF software is a complex and multi-faceted process that requires traditional financial software testing methods while also considering the characteristics of blockchain technology, cryptocurrency markets, and strict regulatory requirements [1] - Key technical challenges include data accuracy and completeness testing, integration testing, performance and stability testing, and security testing [3][4] Group 2 - Market data source validation is essential to ensure the software can accurately and in real-time retrieve prices and trading volumes from major cryptocurrency exchanges and data providers [5] - NAV (Net Asset Value) calculation verification is a core function of ETF software, requiring rigorous testing to ensure accurate daily or real-time NAV calculations based on holdings, market prices, fees, and dividends [5] - Consistency of holding data must be tested to ensure the ETF's displayed holdings align with actual assets managed by custodians [5] Group 3 - Compliance and regulatory requirements testing is crucial, including the generation of regulatory reports and monitoring of investment restrictions [8] - Error handling and recovery testing are necessary to ensure the software can manage external system failures and recover from crashes while maintaining data consistency [8] Group 4 - The testing process must incorporate various methods such as automated testing, manual testing, penetration testing, and performance testing, requiring close collaboration with fund operations, compliance, and security teams [7] - The rapid changes in the cryptocurrency market and related technologies necessitate continuous updates to testing strategies and use cases [8]
