Second: Combine "context builder" and "market data" to build the whole database. The "market data" mentioned here mainly takes Binance exchange as the main object of observation, and integrates the direction of inflow and outflow of USDT and USDC in the hot wallets on the ethereum chain controlled by Binance, and observes the time period of nearly 500 blocks and about 100 minutes. It can reflect the current flow of funds, and market sentiment.
