ChainCatcher message, CKB community member Retric proposed the Nostr Binding Protocol, where Nostr is an information distribution protocol suitable for large-scale adoption in consumer applications.The Nostr Binding Protocol creates a one-to-one mapping relationship between Nostr Events and CKB Cells. Ordinary users can create and distribute native assets on the Nostr social network based on this protocol, and through RGB++, these assets on Nostr can also be controlled by Bitcoin addresses. Client developers can build products on it; unlike ETH dApps which split into two systems (one being off-chain servers and the other on-chain smart contracts), the Nostr Binding Protocol brings a new development paradigm for dApps, using a consistent system with different data levels to build dApps.It is reported that the Nostr Binding Protocol can be seamlessly integrated into the CKB Lightning Network in the future, addressing the native payment issues in social networks. The CKB Ecological Foundation will promote consumer applications based on the Nostr Binding Protocol to land in the BTC ecosystem.
