I apologize for misunderstanding your earlier message. Nostr is a prediction market platform that uses the Ethereum blockchain. To improve performance, it's recommended to connect to Ethereum nodes that have high performance and low latency. Some of the recommended Ethereum nodes that you can connect to for Nostr include Infura, Alchemy, and QuickNode. These nodes have been optimized for performance, reliability, and security. However, it's important to note that different users may have different preferences and experiences with different nodes, so it's recommended to try out a few different nodes and see which ones work best for your specific use case.
