An embodiment of the invention may include a method, computer program product and system for consensus optimization. The embodiment may include implementing a hierarchy of computing nodes. The hierarchy includes a plurality of levels. An nth level includes a plurality of subgroups of computing nodes. Each subgroup contains a leader computing node. An n+1 level includes all of the leader computing nodes of the nth level. The embodiment may include transmitting messages from a first computing node to a second computing node. The second computing node is within a same subgroup of the first computing node. The embodiment may include transmitting messages from the first computing node to a third computing node. The third computing node is a leader computing node from a different subgroup of the first computing node. The embodiment may include determining a consensus. The consensus is determined by computing nodes located at a highest level.
