How to find the total pow hash rate of Steem network? Is it "total_pow" field in info?
A more accurate measure of TOTAL POW effort would be "num_pow_witnesses" which is about 105 (near all time high).
total_pow = sum of num_pow_witnesses over all blocks, a blockchain with the most total_pow has the highest average difficulty, while the one with the highest num_pow_witnesses has the highest current difficulty.
The other number to look at is head_block_number, the chain with the most blocks has had the least missed blocks and therefore is the one the majority of miners are building on.
A fork was created by some miners, but the real chain is:
"head_block_number": 426200,
"head_block_id": "000680d842d8e1f0b7037ff78165a6824185359b",
"time": "2016-04-08T16:50:12",
"current_witness": "aramco",
"total_pow": 1985727,
"num_pow_witnesses": 105,
"participation": "100.00000000000000000"
You can get this information in the cli_wallet using the 'info' command.
You are probably on a fork if you do not see your hashrate update every 3 seconds.
These are the active miners, 100% of the miners scheduled have been producing on the main chain.

We are investigating what caused some miners to get lost, but it appears that most are are the proper chain based upon the POW difficulty.
