  Edge computing is a novel paradigm designed toimprove the quality of service
for latency sensitive cloud applications. However, the state-of-the-art edge
services are designedfor specific applications, which are isolated from each
other.To better improve the utilization level of edge nodes, publicresource
sharing among edges from distinct service providersshould be encouraged
economically. In this work, we employ thepayment channel techniques to design
and implement EdgeToll,a blockchain-based toll collection system for
heterogeneous public edge sharing. Test-bed has been developed to validate
theproposal and preliminary experiments have been conducted todemonstrate the
time and cost efficiency of the system.
