Abstract: The off-chain payment channel network has problems such as the inability of user nodes to choose the transfer method according to actual needs, and the low fault tolerance rate caused by only using a single path to initiate transactions in a single routing. This paper proposes an alternative multipath payment scheme (AMPS) based on the off-chain payment channel network. This scheme provides user nodes with three forwarding options according to actual needs, i.e., the shortest distance priority, the lowest handling fees priority and the comprehensive measurement of the distance and handling fees. In AMPS, we improve the open shortest path priority protocol and construct multiple paths to forward payments in parallel according to different priorities selected by the nodes. Compared with previous schemes under a single route, the scheme AMPS significantly improves the transfer payment success rate. At the same time, the receiver nodes can actively release other paths once immediately the transfer is successful, which improves the transfer payment performance of the whole network.

Key words: blockchain, scalability, off-chain payment channel, alternative multipath payment, payment success rate
