In this paper, we present a novel distributed certification system in which signing a certificate needs the collaboration of a fixed ratio of the nodes, hence a varying number of nodes. This number is dynamically adjusted to enforce the ratio in a fully distributed way, which is mandatory for decentralized varying-size P2P networks. A certificate allows then to link the key pair of a node to some rights granted to it.
