The Tether Challenge involves building a cryptocurrency data pipeline using JavaScript, Hyperswarm RPC, and Hypercore. It requires fetching price data for the top 5 cryptocurrencies (against USDt) from CoinGecko, calculating the average price from the top 3 exchanges, and handling data quality issues while minimizing storage requirements. The data must be stored using Hypercore/Hyperbee databases and be accessible via Hyperswarm RPC with methods for fetching latest and historical prices.
