WebTo accomplish these objectives, we use two well-known graph models of Erdös-Rény and Barabási–Albert in order to study the blockchain network topology. We also adapt our model to study the impact of deploying a relay network and investigate the effect of the relay network size on the network performance and decentralization of PoW-based ... WebJun 28, 2011 · The Barabási–Albert model (BA model) [1] is perhaps the most widely studied graph process governed by preferential attachment. A new vertex is added to the graph at each time step and is joined to m existing vertices of the graph chosen with probabilities proportional to their degrees.
