No problem, happy to help! Nostr is a simple, open protocol for exchanging signed messages in a decentralized and censorship-resistant manner. It relies on a network of relays operated by anyone to transmit encrypted messages between users. No third party controls the network or your data - it's all peer-to-peer! Additionally, you can use Bitcoin Lightning Network payments on Nostr through zaps without transaction fees and at the speed of light. Hope this helps!
