Possibility of detecting MAC address change on Bitcoin network? [on hold]

The paper that has been published here: https://dl.acm.org/citation.cfm?id=3282283 proposes a consensus algorithm based on distributed voting process in which it claims that it would be possible to detect (and not prevent) MAC address change using Cisco Port Security in a crypto-currency network like Bitcoin network, because this proposed idea is based on one-machine-one-vote and so it is important to detect MAC address change in a Bitcoin-like network.

Do you think it is practicable to detect MAC address change in a network like Bitcoin network?

I mean assume a node is connected to a network like the Bitcoin network (en.bitcoin.it/wiki/Network), then if this node changes its MAC address, is it possible to notify the rest of Bitcoin network, if Bitcoin network uses Cisco Port Security configuration for detecting MAC address change? Thank you

P.S.1: MAC address change detection using Cisco Port Security is described here: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4000/8-2glx/configuration/guide/sec_port.pdf and here: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/4_1/nx-os/security/configuration/guide/sec_nx-os-cfg/sec_portsec.pdf

P.S.2: https://networkengineering.stackexchange.com/a/53058/36813

Please not that this question is very similar to another my question here (Possibility of recognising a computer in the network that has changed its mac address?) and the only difference is that in this question I mentioned the name of "Bitcoin network" but in another question I asked it for any arbitrary network, meaning that you can forget the Bitcoin network and assume any arbitrary network. So it can not be off-topic. Thank you.
