CKB releases the next-generation public lightning network Fiber Network, and the testnet will be launched this week. Fiber Network is a next-generation public lightning network built on#Nervos$CKB and off-chain channels. It can provide fast, low-cost and decentralized multi-currency payments and peer-to-peer transactions for RGB++ assets. Similar to the#Bitocinlightning network, Fiber Network is a second-layer payment channel expansion solution that conducts transactions off-chain to increase transaction speeds and reduce fees while maintaining the security and decentralization of the blockchain.
