Hi! I read that each Atlas node stores full replicas of all data items. I understand that each data item is small, and that registration of a data item in BNS is not for free, so I expect an Atlas instance to not take that much space.
But still it would be good to get an intuition of the average disk space taken by typical Atlas instances today and the rate of growth over time. Depending on the space taken, that may limit the possible applications of Blockstack on various types of devices. My use case in mind is mobile and/or IoT.
