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.
Each SP and all edge routers are running in separate Autonomous Systems (ASes). There are 12 AS which are connected to each other with eBGP neighbours. We have used full mech iBGP neighborship to connect routers inside an AS. This could be based on Route Reflector.
