@honglu69 - thank you - I've been CPU mining with the cheetah_cpuminer on neng - but noticing that it is not really mining all that much - not like CHTA - so wondering if I should just abandon the idea - if it's not really worth CPU mining. Is the ideal blocktime 1 min or what? I have my cpuminer interval set at 240s.. should I adjust it?

for CPU mining NENG, yes, the reward is much less.  The current recommended approach is "dual mining" both NENG + CHTA, so the main profit is CHTA, NENG is extra.  There are reasons for NENG profit to be much less. mainly the cheetah effect is much weaker on scrypt,  many cheetah blocks are mined not by CPU, but by ASIC miners on solo or pool mining mode.  100% dedicated CPU mining NENG on PC or phone may not be worth it for now.
the NENG side wait time is 2 minutes,  after two minutes, "cheetah_cpuminer" will kick in and start mining on CPU.  dual mining works because many times the CPU is idle.  It mines NENG while CHTA is idle,  or mines CHTA while NENG is idle on CPU.
interverval is same as CHTA,  say your phone has 8 CPU, here is recommended command in phone for NENG in another screen session:
    python  main.py --interval 10 --cpu 6
8 CPU,  leave 2 CPUs for NENG/CHTA wallet to sync and other system tasks,  use only 6 CPUs for CPU mining NENG.   same command for NENG or CHTA on different folder of  "cheetah_cpuminer".     My neng folder on phone is "cheetah_cpuminer",  my CHTA folder is "cheetah_cpuminer_chta" folder, both run in same phone, on different screen sessions
in rare cases, sometimes both CHTA and NENG are kick in mining together, when that happens, my phone uses 4 CPU mining NENG, 4 CPU mining CHTA, that is OK for short period.  Most of time, they do not mine together, therefore dual mining gets more profit on CPUs on phone or PC.

Thank you for the explanation. 🙂

I know this has probably been asked several times, but is there a reason as to why PoW isn't more profitable with a more powerful desktop processor than my phone?

***[1:58 AM]***I can't find an explanation

I am not hardware electrical engineer guru, so this is just my own explanation and observation. It has been reported by so many members, it is true that android phone outperform PCs on CPU mining on CHTA for proof of work mining. On cheetahcoin core level, the mining is mainly about math calculation competition on sha256. No other coins are interested in CPU mining on SHA256. SHA256 is bitcoin mining, and CPU mining on bitcoin has long been dead until CHTA come alive. So we are probably the only coin there focusing on CPU mining on bitcoin's algo. My take is, arm CPU is far superior on SHA256 math calculation than Intel or AMD chips, on CPU level. Check out their differences. arm CPU has different design compared to AMD/Intel, and different philosophy. For now, arm CPU wins on SHA256.

power efficient is one aspect, more than that. less power, more profit. android phone mine more CHTA coins than "equivalent" Intel/AMD PCs. far more.

***[12:09 PM]***Nobody did actual data comparison. I saw one member did both. I only do android phone mining, dual mining CHTA + NENG, I no longer mines on PC, I have no number to speak of.

***[12:10 PM]***The number I saw is "double". Expect double amount of CHTA coins mined when equivalent CPUs on Intel/AMD vs arm64 phone on "cheetah_cpuminer" method.

I see, because I was intrigued when a friend said that their phone mines faster than their PC. He thought it was due to difficulty being reset, although I assume this is false, as both architectures should get affected by this. But do you think it's just the SHA256 hashing process that takes more time? If so, it wouldn't be hard to test this theory, by making hashing functions for both platforms, cross compiling them, and disassembling them and benchmarking the individual instructions (edited)

Yes, I think it is "SHA256 hashing process".

Hello Fellow Nengsters!

The donation giveback event has ended. Thank you all who have donated and we appreciate your donation!

The Nengcoin Treasury Fund has raised 585,147,583.581 NENG and the funds will be used for future projects like marketing etc.

Through further communication between Dev Hong and SouthXhchange support, we were notified by SouthXchange support that we had a total loss of 6.3 Billion NENG on this 51% attack event and not 4.25 Billion NENG which we had originally thought because 2.05 billion NENG on the account that Dev Hong personally owns from his prior mining and open market purchase was already deducted from this 4.25 billion NENG loss calculation. Dev Hong gladly agrees to contribute this 2.05 billion NENG to our NENG Treasury Fund to cover the 51% hack loss. We were further notified by SXC support that all other members of NENG community will have no hacking loss on trading/deposit/withdraw on NENG and all the prior trades on NENG are honored by SouthXchange with no roll back.

Now that the SXC event is over we will move forward and make sure no 51% attacks happen in the future with this significant security enhancement of v1.9.x hard fork upgrade.

We want to thank all Nengsters for your patience and understanding throughout this tough period!

As always Happy mining & Trading!
