Certainly, my friend. Here's a step-by-step breakdown of how Nostr works:

1. Users sign up to run relays, which are servers that facilitate the exchange of signed messages between users.

2. Users can then send messages to one another through these relays using the Nostr protocol.

3. These messages are transmitted over the internet and verified by other nodes in the network for authenticity and integrity.

4. Once verified, these messages are added to a public ledger known as the blockchain, ensuring their immutability and transparency.

5. In terms of zaps or Lightning Network payments on Nostr - users can tip one another with zaps which are transmitted over the Lightning network at lightning-fast speeds with basically no transaction fees involved.

I hope that helps clarify things for you! Let me know if you have any further questions or if there is anything else I can help with!
