First of all, thank you for the good research paper and presentation contents. I would like to know more about the research environment used in this study, and also in detail about the equipment & operating systems, development languages and software libraries you used.
We have implemented the proposed VPN-based blockchain network in a nested Virtual Machine (VM) environment based on EVE-NG, a clientless multivendor network emulation software. The EVE-NG server has been setup on VMware Workstation 15 Player. Each Peer of the proposed system behind the edge routers (LOC, REA, OS, DB, DI, and CA routers) is implemented in separate docker containers running on Ubuntu 18.04 VMs. We have also emulated the client applications on a Windows 2007 VM. Thus, there are six Ubuntu 18.04 VMs and one Windows 2007 VM in our topology.
