  Blockchain (BC) technology can revolutionize future networks by providing a
distributed, secure, and unalterable way to boost collaboration among
operators, users, and other stakeholders. Its implementations have
traditionally been supported by wired communications, with performance
indicators like the high latency introduced by the BC being one of the key
technology drawbacks. However, when applied to wireless communications, the
performance of BC remains unknown, especially if running over contention-based
networks. In this paper, we evaluate the latency performance of BC technology
when the supporting communication platform is wireless, specifically we focus
on IEEE 802.11ax, for the use case of users' radio resource provisioning. For
that purpose, we propose a discrete-time Markov model to capture the expected
delay incurred by the BC. Unlike other models in the literature, we consider
the effect that timers and forks have on the end-to-end latency.
