Systems and methods are provided for specifying a link recommendation. Such a link recommendation can recommend a particular multi-link operation (MLO) link between an access point (AP) multi-link device (AP MLD) and a non-AP MLD, such as a client device or station for use when exchanging data frames. Conventional usage of MLO can result in non-AP MLDs attempting to associate to a particular AP MLD over the same link, which can result in overloading of that link. This is because the implementation of MLO elevates the context of AP-client device/station association to a higher level, i.e., the device/MLD level, and the link on which data frames are sent or received between an AP MLD and a non-AP MLD s no longer a consideration/relevant. However, the transmission of link recommendations indicating links to use (or to avoid), avoids or lessens the risk that multiple non-AP MLDs attempting to associate to an AP MLD will overload or overuse the same link.

This process can be repeated until a desired level of learning has been achieved. The public and private keys are never revealed to the same node, and may be permanently discarded after use to further ensure privacy.
Systems and methods are provided for leveraging blockchain technology in a swarm learning context, where nodes of a blockchain network that contribute data to training a machine learning model using their own local data can be rewarded.
