CKB community member Retric proposed the Nostr Binding Protocol. Nostr is an information distribution protocol suitable for large-scale adoption of consumer applications.

The Nostr Binding Protocol is used to create a one-to-one mapping relationship between Nostr Event and CKB Cell. Ordinary users can create and distribute native assets in the Nostr social network based on this protocol. Through RGB++, these assets on Nostr can also be controlled by Bitcoin addresses. Client developers can build products on it. Unlike ETH dApp, which is divided into two systems (one is the off-chain server and the other is the on-chain smart contract), the Nostr Binding Protocol brings a new development paradigm to dApp. It uses a consistent system with different data levels to build dApp.

It is reported that the Nostr Binding Protocol can be seamlessly integrated into the CKB Lightning Network in the future to solve the problem of native payment in social networks. The CKB Ecological Foundation will promote the implementation of consumer-level applications based on the Nostr Binding Protocol in the BTC ecosystem.
