Rethinking Incentive in Payment Channel Networks

Cryptocurrencies and their underlying blockchains suffer from the scalability issue: they do not support efficient transaction processing. Payment channel networks were designed and implemented to alleviate the scalability issue. However, payment channel network is far from solving the scalability issue due to its routing fee, inefficient rebalancing, and limited accessibility. We propose the Practical Payment Channel Network. The Practical Payment Channel Network aims to minimize the routing fee, improve the rebalancing efficiency, and make payment channel network accessible to the general public.
