A method for concurrent training and updating a machine learning (ML) model at an edge node in a peer to peer network using a certifying node is provided. The method includes performing an incremental training of the ML model by a first edge node based on one or more data points associated with a data event. The first edge node ML transfers the incrementally trained ML model to the certifying node. While awaiting a response form the certifying node, the first edge node receives a certified ML model from the certifying node. The certified ML model originates from a second edge node. The first edge node performs an incremental training of the received certified ML model based on one or more data points by re-applying the data points associated with the event data. The first edge node transfers the incrementally trained ML model to the certifying node for certification.
