Do you know how many public Blockstack nodes are there? I can’t find any estimate number.

My node knows of 19 other public nodes with which it has regular contact.
$ sqlite3 ~/.blockstack-server/atlas.db 'select * from peers;' | wc -l
19
This is a lower bound, since these are only nodes that have publicly-routable DNS names or IP addresses. For example, I know that at least one of the “nodes” – node.blockstack.org – is actually a load-balancer for several NAT’ed nodes. Unlike Bitcoin nodes, Blockstack Core nodes don’t communicate across NATs (yet).
