With this post I'm going to test the "proof of work" setting of the Gossip Nostr client application. Let's try a setting of 21 leading zero bits.

This didn't work. Now lets try again after a restart of the application...

That worked. Now with 22 bits without a restart...

PoW setting disabled, no restart.

Again 21 bits with no application restart. If this works now, then that means I forgot to push the "save settings" button before sending my first test note :-)

Timing test with a POW setting of 25

Another timing test, POW=27

Second timing run with POW=27

For the record: POW=27 required 120s here for the first run and 250s for the second run. I stick with POW=25 for now, just for fun.
