CPU Mining randomSpike sha256/scrypt with Cheetah_Cpuminer on Android/PC/Mac

[honglu69]

Nengcoin (formerly NewEnglandcoin)  is a scrypt coin minable in android phones, chromebooks, PC/MacOS along with GPUs and ASICs.   It has randomSpike ago on top of scrypt to restrict ASIC.  ASIC vs CPU mining profit split is about 80%/20% in average although real time mix is dynamic from 100% ASIC to 100% CPU from time to time.

Nengcoin (NENG) CPU mining use special software "Cheetah_Cpuminer".  The latest version is v1.3.0
https://github.com/ShorelineCrypto/cheetah_cpuminer/releases

README Document:
https://github.com/ShorelineCrypto/cheetah_cpuminer

What is Cheetah_Cpuminer?
Nengcoin (NENG) blockchain has dynamic difficulty adjustment algorithm which may trigger ASIC miners to get stuck on NENG blockchain finding no blocks from several minutes to several hours.

Cheetah_cpuminer will automatically start mining at local PC when ASIC miners get stuck. Cheeta_cpuminer will stop mining when ASIC miners are smoothly generating blocks

v1.3.0 is tested under android phones, chromebooks,   Windows 10,  macOS from  El Capitan to Catalina and Linux on 9 distros (Ubuntu/Linux Mint, Debian/MX Linux, Arch/Manjaro, Fedora, openSUSE, Solus)

Update: latest supported coin include Cheetahcoin (CHTA).  A randomSpike Nengcoin fork on SHA256. CHTA is supported on chta beta branch in github.

i see this as a pointless endeavor.  it doesn't matter whether the asics are stuck for several minutes to several hours, the difficulty will still be based upon such a high difficulty do to the ASICS just mining, that the miner is now paying to mine the coin with thier cpu with no possibility of any return.

it's a novel idea, but a pointless endeavor.   You have a better chance of return if you buy a lottery ticket.

I of course disagree with "pointless endeavor" view.   For the moment,  this algorithm change is merely to make NENG CPU minable coin.  This is breaking the monopoly of ASIC centralization mining.
Decentralization is always goal of bitcoin, litecoin or dogecoin or NewEnglandcoin cryptocurrencies.   Over the past several weeks when I alone ran alpha version of Cheetah, roughly 10% to 20% of block rewards were obtained by CPU miners. The majority went to ASIC miners.  My 10 year old 2 core linux PC yielded 1 million NENG per day in average.  Some rare lucky days my Linux running cheetah obtained 5 million NENG per day

What you are correct is that the cost of CPU mining of NENG is much higher than ASIC.  Therefore, I foresee the current CPU miner of NENG are casual miners. When one
use PC (linux or window),  just run cheetah to get some reward.  Then shut down when one sleep.   Another usage are for those masternode  Linux miners.
Masternode software does not take much CPU or memory resources.  Just run a version of cheetah, and NENG full node within the same cloud linux machine, then obtain additonal rewards with no additional cost.

Wait for my release of technical white paper of NewEnglandcoin within days.  I will explain  next level dynamic difficulty algorithm upgrade to be used against 51% attackers and to secure the NENG blockchain.

The current version only support Linux.  Wait for next version, which will support Window CPU mining. I expect no later than end of Jan 2019 to release the next version
upgrade for Cheetah.  Watch closely on DISCORD or NENG bitcointalk/Marinecoin Forum Ann threads.

Technical Whitepaper of NewEnglandcoin (NENG) explaining the current and future dynamic difficulty algorithm proposal released:
https://bitcointalk.org/index.php?topic=5027091.msg48990334#msg48990334

This white paper explained the purpose of the dynamic diff algorithm and why CPU mining on NENG with Cheetah_Cpuminer software is good for security and decentralization.

The v1.1.0 version is out supporting both Linux and Windows:

[honglu69]

Note for Windows CPU Miners
Even if the wallet is fully synced under window machine, you may have to double click the bat file, stay for couple of minutes and then close it, and restart it again to allow cheetah to work properly. Somehow cheetah bat file may not work with the first try.

Cheetah_cpuminer v1.1.2 is released at github.  This version added additional support for Mac platform.

[honglu69]

NewEnglandcoin v1.2.0 was released to have hard fork to enable anti-instant mining and anti-51% features.

NENG v1.2.0 Hard Fork has been major success!

Research on first forked 50 blocks confirmed that shortest block time was 4 seconds.  Essentially fast block time or instant mining has been stopped.  Historically, fast blocks would
be 1 in 20 blocks , some times 1 or 2 blocks within 10 block stretch.  The dynamic diff algorithm implemented in v1.2.0 is working.

Of the first forked 50 blocks, 17 blocks were mined by CPU miners,  33 blocks were mined by ASIC or GPU miners.  In other word, the first 50 blocks under new algorithm, ASIC/GPU miners got 66% of total rewards, CPU miners obtained 34% of total rewards.  Ratio split on ASIC/GPU/CPU miners are not constant, could be subject to changes depending the difficulty and mining rigs distribution.  However, this 66/34 split of rewards is within expectation of our original plan for the v1.2.0.

NewEnglandland v1.2.1 released at : https://github.com/ShorelineCrypto/NewEnglandCoin/releases

This is security update to have checkpoints on block 278008 to secure the hard fork.  This is recommended for upgrade for all users.


The v1.2.x  version branch of NENG update does not change CPU mining with Cheetah_Cpuminer software that much.  
It does change the mix of miners advantages a lot.

In the v1.1.x version of NENG wallet,  NENG was mainly a ASIC/CPU minining coin.  60% to 80% blocks rewards went to ASIC miners, 20% to 40% went to CPU miners.

In the v1.2.x version appears to favor GPU miners favorable significantly.  GPU miners probably can obtain 50%  to 60% of blocks rewards,  CPU and ASIC split for the 20% each.
It is still early on the hard fork.  But CPU miners are not affected by this new upgrade on hard fork that much.

Cheetah_CpuMiner officially suport linux  Ubuntu 18.04  machine.  Readme documentation on front page has been updated on Ubuntu 18.04 CPU mining on NENG:
https://github.com/ShorelineCrypto/cheetah_cpuminer

[honglu69]

There are a lot more CPU miners on NewEnglandcoin  than months ago when I first posted this thread.  At that point, my old linux PC can mine 1.5 million NENG per day on Cheetah.
Now the reward is much less, maybe 1/5 of what used to be.  Still CPU mining can be fun and less demanding if you only do it casually on your own PC when you work or read online. It can be on low resource without affecting other activities.  It adds a reward on Desktop PC or laptop.  Running a full node,  mining 300,000 NENG per day on a PC is still quite impressive rewarding CPU mining experience.

GPU solo miners and small ASIC solo miners probably are the dominant force on DynDiff Scrypt coin NENG mining together with CPU miners.  Big ASIC miners are disadvantaged by the new algorithm hard fork upgrade recently.

New version of Cheetah_Cpuminer  v1.1.3 was released to support macOs Mojave.

Cheetah_Cpuminer v1.1.4 released.

This version mainly fixed a bug on PATH for Windows 10 platform

The  video part 2 stopped waiting for the results.  The end result was that yes indeed,  the block was mined by Cheetah and showed up in the wallet for 20,000 NENG reward in the 4-core CPU WIndows 10 PC shortly after the video recording ended.

cheetah_cpuminer v1.3.0 released - fixed timestamp attack
This new version is released at cheetah_cpuminer at:https://github.com/ShorelineCrypto/cheetah_cpuminer

This new version of cheetah_cpuminer allows all cpu miners on android phones, computers, chromebook tablets to get a share of mining rewards when a big CPU miner attacks NENG with timestamp.

If your computer, chromebook, android phone already has a version in running, you can do below to upgrade:
(1) kill your cheetah CPU miner
(2) delete old cheetah_cpuminer software, re-download software
(3) restart cpuminer as before.

For android phones or linux, you can do below as easy upgrade using git command:
(1) step one: Ctr-C to kill the running cheetah_cpuminer
(2) under the folder "cheetah_cpuminer" or cd to it if not in that folder:
$prompt: cd cheetah_cpuminer
$prompt: git pull
(3) restart cheetah_cpuminer as before.

Is this coin listed on any exchange?  It appears to be a couple of years old...but i cannot find it listed by any coin site or on any exchange.

I found it....took some digging.
