Something is very weird, or at least I don't understand it:
ROI block explorer shows network hashrate: 290.6160 KH/s (current block 79777)
1. Suprnova pool: 285,859.434 KH/s (current block 79777)
2. Optiminer pool: 26180.1h/s (current block 79778)
3. Coinspool PoolL 5 kH/s (current block 79778) (yes there are still some people there)
Three pools together make approximately 316 KH/s while block explorer is on 290 KH/S !?
What about solo miners, they add some mining power too??
Network hashrate is not reflecting agregated hashrates across pools and wallet miners.
Pretty sure the website shows the average over a period of hours
Elbandi explained this before in this thread:
"Network hashrate come from daemon, it's calculated from average hashrate from last 120 blocks. Pool hashrate is current value, it is calculated from miners sharerate."
Thanks for shedding some light on this matter. That must he something Elbandi wrote really doing the first few days or weeks of this forum and I missed it or I forgot about it.
