Abstract: Disclosed is a distributed computer system that includes a plurality of worker nodes that are coupled together via a data communication network to exchange data therebetween, wherein collective learning of the worker nodes is managed within the distributed computer system. The distributed computer system comprises a data processing arrangement operable to cluster the plurality of worker nodes into one or more clusters, wherein worker nodes of a given cluster train a computing model by employing a respective secondary distributed ledger. The collective learning from the plurality of worker nodes is coordinated using the distributed ledger arrangement.
