QSO Data

1. 1. QSO flow

When a new QSO is entered at a node, A [JSON](https://www.json.org/json-en.html) representation is created and:

• Appended to the local journal file.
• Broadcast to all active nodes via IP Multicast.

QSO is immutable e.i. it canno change. The uuid always refers to the exact same QSO.
