Android Phone dual mining report on NENG/CHTA
Old Android phone, 4 core, 8 CPUs in UserLand app linux.
24 hours mining results: zero NENG, 20,000 CHTA.
NENG had resets with low diff, not surprising no reward. Also timestamp attacks days ago, zero for last several days also. Probably will change after hard fork. Cheetahcoin side reward is still good on dual mining mode, down a lot recently partly due to competition, partly due to timestamp attack recently. CHTA results hit miss, some day zero, other days 1 or 2 blocks on the phone.

Iquidus explorer For Nengcoin Upgraded
Iquidus is popular open sourced block explorer software for many cryptocurrencies.
Iquidus explorer for Nengcoin was upgraded and tested. The previous version v1.6.1 on Neng explorer had problem of extremely slow block syncing in mongo database. The upgrade fixed this issue. Now the full Nengcoin block syncing from genesis block to latest block ( 2.69 million blocks for 2+ years) can be done in a few days.

What's Dual Mining?
"Dual Mining" is the process of running cpu-mining software for sister-projects Nengcoin and Cheetahcoin at the same time. This is possible thanks to their use of the "Cheetah Effect Algorithm" - the miners only run for short bursts of time(when more powerful ASIC & GPU mining rigs get stuck on a block), allowing them both to operate in harmony while using little resources. This allows you to effectively double your mining prospects. The best thing about dual mining is that it can be done on Android!

That tracking page is no longer that useful.
CRPool is on wrong chain (v1.5.x), not valid after hard fork.
CMinors and Findblocks Pool are only two working pools now with correct chain on v1.6.x
base diff just reset to low overnight, boom for USB ASIC solo miners

How to Fix Android phone CPU Glitches
My android phone is 4 core android with 8 CPUs in UserLand app linux. I ran below in phone for dual mining Nengcoin/Cheetahcoin almost 24 hours per day, 7 days per week.
However, about once per month, my phone had wacky behavior. This CPU glitch was reported by other members too.
So when the cheetah miners start to mine either of coins, the cpu usage should hit 600%. However, it had wacky behavior that the cpu usage stuck at no more than 400%. The wacky behavior also almost mined no coins. Two phenomena of this wacky behavior:
(1) CPU usage never be higher than 400%
(2) in cheetah miner prompt print out, instead of every 10 seconds, it get wacky:
Root cause of this issue is unknown. However, there is fix as below:
shut down UserLand app, reboot android phone, then restart UserLand app two coins wallet would fix this phone CPU glitch.

Hi
this is quite frustrating spools.online down agian, i hope this pool becomes stable and if pool operator is performing and upgrade or maintenance then a news feed on website explaining all would be a benifit.
i hope this come back online soon plus there was a lot of coin pending and waiting to be paid out i hope i get this and it doesn't get wiped or burned.
Update !!!!

I noticed that too. Cminor seems to be more stable pool. There seems to be DDOS attack recently on pools, which might be reason for offline so much on pools

How to Guess Reset on NENG/CHTA
Use explorer to check the latest block, calculate the block timer per block:
https://cfpool.eu/explorer/CHTA
https://spools.online/explorer/NENG
CHTA target 2 minutes per block, NENG targets 1 minute per block. Check last 20 blocks average block time. If it is extremely slow, much slower than targeted and desired block time target, you can guess reset is coming soon.
Each difficulty adjustment time is a chance for reset. Divide the block number by 1440 (for NENG) or by 720 (for CHTA). Each time algo will decide reset or not, reset means difficulty to all time low to cheetah diff, adjustment on difficulty is simply up or down mildly say 30% for base difficulty.
