According to Foresight News, CKB released a light paper on the next-generation public lightning network Fiber Network. Fiber Network is built on Nervos CKB and off-chain channels, providing fast, low-cost and decentralized multi-currency payments and peer-to-peer transactions.

At present, Fiber Network has completed the prototype development, realized the basic functions of channel creation, update and closing between two nodes, and verified the cross-chain function with Bitcoin Lightning Network. The network will be launched next week and start testing.

CKB said that Fiber Network is similar to Bitcoin Lightning Network. It is a second-layer payment channel expansion solution that conducts transactions off-chain, improves transaction speed and reduces fees while maintaining the security and decentralization of the blockchain. Fiber Network supports multiple types of assets, including CKB native tokens and any RGB++ assets. Its overall architecture includes core modules such as off-chain payment channels, on-chain contracts, multi-hop routing, and monitoring services.
