+# CKB Fiber Network Node
+
+CKB Fiber Network Node (cfn-node) is a reference implementation of a CKB Fiber Network protocol (cfn-protocol). In the current stage, it's not a production-ready implementation, but a prototype to demonstrate the feasibility of the cfn-protocol. It's capable of:
+
+* Establishing connections with other cfn nodes
+* Creating and closing fiber channel
+* Payments over fiber channel (via [cfn-scripts])
+* Cross-chain asset transfer
+
+Please note that the implementation is still under development, there are two major features not implemented yet:
+
+* Watchtower service to monitor and revoke on-chain transactions
+* Multihop payments
+
+But as a prototype, it's a good starting point for developers to understand the cfn-protocol and try out the integration with their applications.
