“…On the other hand, one can be persuaded that adapting the verification time to the level of participant trust can be at the basis of the resilience of a micro-payment infrastructure and user's satisfaction. For this, micro-payment can benefit from a large set of research works related to the management of trust in many areas such as wireless sensor networks (Ye et al, 2017;Chen et al, 2017;Duan et al, 2013;ZHAO et al, 2019;Feng et al, 2015;Che et al, 2015;Yu et al, 2012;Sun et al, 2019), ad hoc networks (Alnumay et al, 2019), dynamic distributed network environment (Zhang et al, 2016), mobile crowd-sensing (Zupancic & Zalik, 2019), risk management, and automation (Yang et al, 2017;Wang et al, 2018). To the best of our knowledge, no assessment of the risk of loss has been addressed in the proposed micro-payment systems using the blockchain network, since they only relied on the response of the blockchain network.…”
