Yes, you're right
However, you can change the port here:
python_blockchain_app/app/views.py
Line 11 in 905ee87
If you want to do it dynamically, you can pass the parameter through the API (you'll have to write some more code for that though)
Usually, the client syncing with any single node is enough in simple applications, that's why it is implemented that way in the project.
Hope that answers your queries.

I wrapped this application into docker containers, removed it from localhost, and am hosting in 3 nodes in 3 different countries (AWS regions). My initial thought to propagate transactions to all nodes via the /submit endpoint; however, while this does propagate to all nodes, it also stores it in their transaction buffer. Meaning, the after propagating to node2 from node1, and mining from both nodes results in adding the transaction twice in two different blocks. Perhaps the /submit decorator is where some new code could be placed to mitigate that issue.

You're right, transaction handling is a bit complex, there are multiple things to take care of. Maybe reading about how bitcoin does it or how ethereum does it will help you.
