In this article, we propose a protocol that binds the basic data structures of the Nostr protocol to the CKB blockchain. Through this binding, we allow native Nostr data to inherit the characteristics of UTXO/Cell on the CKB blockchain, bringing new possibilities to the Nostr protocol based on on-chain mechanisms. One potential use case is issuing native assets on Nostr. The Nostr binding protocol also introduces a new development paradigm for dApps. Instead of splitting your dApp into two systems (one being an off-chain server and the other an on-chain smart contract), we use a unified system with different data levels to build dApps. This is fundamentally different from the Ethereum model.
