Miner submits only a single solution during PoW window

#1

Hi!

I seem to have gotten my node fully running and have a miner connected to it over the network. The miner picks up the PoW at the correct time, but stops mining after submitting only a single solution (takes about 10 seconds to find one).

Is this the intended behavior? From the whitepaper, I understood that the miner would run for 5 minutes and submit as much work as possible to compete for shard and DS Node eligibility.

If you pass the difficulty level on the first try, then yes you are in the network.

I think that makes sense-- So you get the whole PoW window to find a solution at network diff, and if you are able to meet the diff by submitting a single solution, you have the chance of being a shard or DS node?

Yes, that is correct. You will be a shard/DS if you clear the difficulty level. You have maximum 2 PoW submissions per PoW window at the start of a DS epoch.

Mining Wiki

At the start of each DS Epoch, all mining candidates will run the Proof-of-Work (Ethash algorithm) cycle for a 60 seconds window in order to compete to join the Zilliqa network.

  • Nodes that fulfilled the DS_POW_DIFFICULTY parameter will qualify to join as DS nodes.
  • Nodes that fulfilled the POW_DIFFICULTY parameter will qualify to join as shard nodes.

There are a total of 100 TX epochs (each 1-2 min) within each DS Epoch (2-3 hrs). Every 100th TX epoch is known as the Vacuous epoch .

So, how do you know if you are a DS node? This whole PoW detail should be on another WIKI page.
I also mentioned in reply to you on other thread I was showing no getWork.
This seems to answer that problem. Wish someone would have said the miner does NOTHING most of time - like told me 3 days ago when I asked/reasked/etc. Sigh.
