In this paper we address the consensus problem in the context of networked\nagents whose communication graph can be split into a certain number of clusters\nin such a way that interactions between agents in the same clusters are\ncooperative, while interactions between agents belonging to different clusters\nare antagonistic. This problem set-up arises in the context of social networks\nand opinion dynamics, where reaching consensus means that the opinions of the\nagents in the same cluster converge to the same decision. The consensus problem\nis here investigated under the assumption that agents in the same cluster have\nthe same constant and pre-fixed amount of trust (/distrust) to be distributed\namong their cooperators (/adversaries). The proposed solution establishes how\nmuch agents in the same group must be conservative about their opinions in\norder to converge to a common decision.\n
