Data Collection and Preprocessing

Multi-Source Data Aggregation:

  • Real-time crawling of on-chain transaction data from major blockchains such as BNB Chain, Ethereum, and Polygon (e.g., NFT trading volumes, staking pool liquidity, whale wallet movements), processing over 1 billion data entries per day.

  • Integration of social media platforms (Twitter, Discord) and off-chain data sources (e.g., Dune Analytics, Nansen) to build sentiment analysis models, identifying market trends and early risk signals.

  • Use of vector databases (e.g., Tencent Cloud ES 8.8.1) to store NFT metadata and on-chain behavioral data, supporting millisecond-level similarity search and semantic analysis.
