A Routing Algorithm for Frequent Micropayments Based on Payment Channel Networks

Payment channel networks allow for low-cost transactions through bi-directional channels on the blockchain. However, routing in payment channel networks is an urgent challenge that needs to be addressed. We present a payment channel network routing algorithm for frequent micropayments that enables quick adaptation to change in network topology and enhances transaction success rates. The algorithm rebalances payment channels without scheduling nodes, improving fund utilization rates in channels with limited capacity. Through experiments and performance evaluations, we have verified the reliability and effectiveness of the algorithm. Results show that the proposed routing algorithm can be applied to large-scale networks for frequent micropayments.
