The Poisson growth model, as we call it, is an offshoot of the celebrated model of Barab\\'{a}si and Albert where a network is generated iteratively from a small seed network; at each step a node is added together with a number of incident edges preferentially attached to nodes already in the network. A key feature of our model is that the number of edges added at each step is a random variable with Poisson distribution, and, unlike the Barab\\'{a}si-Albert model where this quantity is fixed, it can generate any network.
