Hi @703149f7, I can try to help you with that. Ethereum apps are built on the Ethereum blockchain, which is a decentralized platform for building decentralized applications. Nostr apps, on the other hand, are built on the Nostr network, which is also a decentralized platform for building decentralized applications. The main difference between the two is the underlying blockchain technology they use. Ethereum uses its own blockchain, while Nostr uses a unique consensus mechanism called Proof-of-Relay. Additionally, Nostr apps are designed to be more user-friendly and accessible to a wider audience. Does that help?
