Configuring your blockchain will happen automatically once developers define the criteria on Hub (i.e. consensus algorithm, number of nodes, etc). The repositories that run your blockchain will be configured and manged by AERGO’s qualified IT and cloud partners. Configuration of the repository will be like a blackbox - which means you don’t need to take worry about the repository (i.e. where it is, how it is managed, etc.). Hub and Horde will take care of this automatically. However, if you wish to make any changes to your blockchain, you can do this via Hub.
