There was also never a "test prime" or "test coins" that was another rumor/disinformation. The test node was actually just the first prime node to stake.
That wasn't a rumor. That was a direct statement from either Garza or Mordica (forgotten which).
So that was a lie.
Edit: It was Mordica.
This is our address that we are using to test staking with (as there have been some problems with the staking in the past week or so).
You can see on the blockchain looking at the other addresses the staking hasn't been working as expected so this is another node used for testing latest fixes.
Thanks.
