Android Phone Dual Mining Nengcoin/Cheetahcoin 24 hours Report

Same 4 core Android phone with UserLand App mining both Nengcoin/Cheetahcoin together simultaneously.  
Results:
Cheetahcoin:  230,000 CHTA
Nengcoin: 40,000 NENG

The phone was not on 24 hours mining. Actually it was used for several hours without mining. But still one day mining result was decent on dual mining.

Both blockchain 24 hours comments:

Cheetahcoin had 140 Th/s big ASIC mining for a short period and then left.  For most of day, Cheetahcoin mining was dominated by CPU solo miners. At some point of day, the domination of CPU mining was 95% and close to 100% at base diff of 1 million, and later at 600k.

Nengcoin blockchain entered into stable phase where the base difficulty has been up or down between 10 and 14.  The CPU miners rewards on NENG has been around 20% of total rewards in recent days.

Android Phone Dual Mining Nengcoin/Cheetahcoin 2 Day Report

Past 48 hours dual mining Nengcoin/Cheetahcoin in same 4 core android phone with UserLand app.  Dual mining NENG/CHTA works because Cheetah_Cpuminer  for most of times do nothing other than observing the Nengcoin or Cheetahcoin blockchain.  In case of heavy CPU usage for mining, when NENG is mining most likely CHTA is idle, when CHTA is mining using up CPU resources,  NENG is most likely idle also. Only on rare cases when both NENG/CHTA would split the usage of CPU resource mining at same time. Dual mining both would therefore double the reward.

Results:
Cheetahcoin:  400,000 CHTA
Nengcoin:  60,000 NENG

For now, android phone mobile mining is more profitable on Cheetahcoin side rather than Nengcoin side for past 2 days.

Base Difficulty Adjustment Engineering Design on NENG

Here is good Q&A in discord on this issue:


honglu69Today at 1:10 PM

@Sefia  This is very good question. This is really about engineering design of NENG on  base difficulty adjustment period.  Nengcoin continues tradition of bitcoin/litecoin/dogecoin on this issue.  In general, the faster the block time, the quicker you want difficulty adjustment, the slower the block time,  you want longer period for difficulty adjustment.

Here are current some stats on bitcoin/litecoin/dogecoin:
 bitcoin adjust base difficulty every 2 weeks and litecoin adjust every 4 days.  Dogecoin adjust base difficulty every 1 day.

Nengcoin is closer to dogecoin, therefore adjust base difficulty for 1 day target  or  every 1440 blocks.  In reality,  the NENG block average time was 2x faster than desired targeted time.   So in average in real life, NENG really adjusted difficulty every half day historically.

Another consideration of this is for good ASIC miners retention issue.  randomSpike has collateral damage for good ASIC miners when a spike block is mined in that for 1 day or 2,  100% of block rewards go to CPU miners and this poses a huge risk to good ASIC miners who provide security and protection on the NENG blockchain.  I would say  good ASIC miners are those rigs that mine NENG 24 hours a day,  7 days a week  providing security for block fee payment in exchange.  If the difficulty adjustment period is too long, then this spike penalty would be too high to piss off those good ASIC miners.  That would not be good.  Good ASIC miners can continue mining NENG even if 1 day or 2 days is nothing after spike,  some days after reset will be huge reward,  some days on spike block mined is nothing, they tend to average out.  This consideration also means that block adjustment period can not be too long in order to entice those good ASIC miners not to leave NENG mining.

Dear  scrypt.ovh pool operator,

I noticed that I mined some dead blocks of Nengcoin on your pool yesterday.  I think now your pool is good now syncing to latest block to the NENG block chain.

It is not a big deal for this issue for now. Just let you be aware of the issues on NENG of your pool yesterday and this may impact future profit of your pool if this happens again.

Also ping me in discord if you are in NENG discord so that I can assign you "pool operator" status in NENG discord channel.

Best regards,

Dev of Nengcoin & Cheetahcoin

Base diff reset hours ealier, boom for GPU/USB ASIC solo miners

Base diff reset to really low level hours ago. Probably too late for GPU, but it still boom for solo USB ASIC miners on NENG.

Android Phone Dual Mining NENG/CHTA Report
24 hours of mining in my 4 core old android phone, dual mining both Nengcoin/Cheetahcoin together. The cheetah_cpuminer flag are same for both in separate screen session of UserLand app linux terminal:
python --interval 10 --cpu 6

The phone has 8 cpu thread.

24 hours dual mining results:
Nengcoin: 30,000 NENG
Cheetahcoin: 60,000 CHTA

The reward is down. Is it because of more competition or because yesterday Cheetahcoin had big reset? Not sure why.

Android Dual Mining NENG/CHTA 2 Day Report
Mined 48 hours dual mining both Nengcoin (NENG) and Cheetahcoin (CHTA) in the same phone.
4 core old android phone. 8 cpu threads under Userland app linux.
Results:
Nengcoin: 130,000 NENG or 13 blocks in two days
Cheetahcoin: 190,000 CHTA or 19 blocks in two days

Again, android phone mining performance on CHTA is better than NENG.

How to Run GekkoScience NewPac and Futurebit Moonlander2 in same Linux server

For those Nengcoin and Cheetahcoin USB ASIC solo miners, you might face difficulty of running both in same linux PC because of USB port conflict.

Here is guide on how to setup both running together happily:

This issue is purely linux issue, may not be issue for windows10  miners.

Android phone mining report - Dual Mining NENG/CHTA
12 hours mining on my 4 core android, dual mining both NENG and CHTA overnight, 60,000 CHTA, 40,000 NENG. That is what I suspected. At least on my phone, SHA256 seems to be more friendly on android phones.

NENG v1.5.0.5 Released for MacOS wallet


NENG v1.5.0.5 released mainly for updated macOS installation script.  Recommended for new macOS NENG users, but not
required for existing MacOS NENG members.
https://github.com/ShorelineCrypto/nengcoin/releases/tag/v1.5.0.5

The change is mainly on the installation scripts side while the binary CLI/GUI files are unchanged.  Homebrew 2.7.0 or later version had major change that deleted [email protected] repos and other API changes.  This script fixed  those issues.

In case you have trouble on latest homebrew version update, you can delete homebrew and reinstall, and use this scripts to setup NENG wallet properly.

Nengcoin congratulate Cheetahcoin launch on github and wallet

Cheetah and Neng run side by side to the moon!

GPU solo mining on Cheetahcoin is good on SHA256:

Spike block mined, CPU mining dominating 100%
About 5 hours ago, a spike block was mined on difficulty = 244000
https://www.reddit.com/r/nengcoin/comments/kxwyy5/spike_block_mined_cpu_mining_dominating_100/

Currently NENG is only minable for CPU solo miners only for about 7 hours.  GPU ASIC can not mine NENG because NENG difficulty = 244000, too high for ASICs
Here is reason for spike, a 4G ASIC is mining NENG hard, triggering this spike:

spike block mined this morning
Here is spike block mined at 244k difficulty at block height 2419020:
https://hashminingpool.com/explorer/NENG?height=2419020

Typically after spike block is mined, almost none of ASIC rigs can mine NENG for any blocks, CPU miners on "cheetah_cpuminer" software very much dominate mining NENG for 100% until reset. Now a big CPU miner is attacking NENG heavily with timestamp method, back and forth 4 minutes ahead or backward. With this timestamp attack, big ASIC rigs are mining into cheetah diff, although CPU miners still dominating, but not 100%. big ASIC rigs are very poor on mining rewards after spike, but at least they are getting some blocks mined on cheetah diff.

Typically, a reset to reset diff (0.000244) will happen after spike block, and boom for GPU solo miners. we will see this time.

Update:  NENG just did a shallow reset. Not good for GPU solo miners, but boom for USB ASIC solo miners on two rotating nodes

NENG Investment Case as DOGECOIN on Steroids

 For those who want to bet on dogecoin on leverage, NENG is the answer.  NENG is dogecoin on steroids, 60,000x cheaper, but no risk of margin call of leveraged bet, and a real coin, not a token.

4th v1.5.x benchmark - phone vs computer vs USB ASIC
24 hours mining report

last 24 hours was nothing normal. Earlier was a shallow reset, fast block, big reward for ASIC rigs and USB ASICs. The middle of day base diff rose to 2, the big cpu miner timestamp attacker jumped in again, dominating CPU mining, sequeezed out pretty much all other CPU miners.

Later NENG blockchain did a shallow reset again, another boom for USB ASIC solo miners.

Here is three group of miner rewards count. Still the benchmark is same for android vs 1 cpu linux using --interval 10 in cheetah_cpuminer.

4 core android (--cpu 6 on 8cpu in UserLand app): 10000 NENG
1 cpu linux: 0

USB ASIC (futurebit Moonlander2) on two rotating nodes : 510,000 NENG

Android phone still managed to obtain 1 block reward in the middle of reset and big CPU timestamp attack. USB ASIC reward is above average, but not as big as yesterday.

No information or prediction for now.  As of today, the dev and community has no money for listing at big exchange because they usually ask for very high price, which currently we do not have.

Community commissioner Sefia (discord) is leading the effort actively looking for external VC funding pitch, raising funds for future development (including, but not limited for listing at bigger exchange) by selling some pre-mined + donated NENG coins we have now.  But obviously I can not predict nor to say whether this will work out any time or not.

Hi,
Thanks for the explain
