Locative is a node collecting game on reticulum. Players visit locative nodes and "collect" them by doing a cryptographically verifiable transaction that's stored on both nodes in a chain of transactions that can't be falsified. The IDs used for this "game" are not associated with a reticulum node ID except by locative announces.
I think it might be fun to be walking around a city, say and collect local transactions over LoRa, or collect nodes across unusual routes from the comfort of your own home.
You can read more about how it works here https://github.com/charlieb/locative
It's pretty early days. I have 3 nodes currently participating. One is in the cloud, one is on my desktop with LoRa and internet interfaces and one is on a pi with only a LoRa interface. I've tested transactions with all three.
Below is part of a session where I exchange announces with the cloud based node, then request a transaction, which goes through, is validate and added to our chain.
The parts that start with *** are my comments to annotate what's happening.
Here's what part of session currently looks like:
