Before revision:  Hence, in this paper, we study the performance achieved in a Fabricnetwork using vertical scaling (i.e., by adding more vCPUs) and horizontal scaling (i. e., by adding more nodes) techniques. We observe that network scales very poorly with both of these techniques.
After revision:  Hence, in this paper, we study the performance achieved in a Fabricnetwork using vertical scaling (i.e., by adding more vCPUs) and horizontal scaling . We find that the transaction throughput scales very poorly with both of these techniques.
