Before revision:  In this paper, therefore, we develop a HLF latency model for HLF-based IoT networks based on probability distribution fitting , by which mean latency prediction is facilitated once probable configuration environments are determined, in terms of the block size, block-generation timeout, and transaction generation rate parameters .
