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.

Server recommended: 2 CPU core linux or more, with Ubuntu 18.04
mongodb v4.2.13
node.js v12.18.4

Software and Nengcoin logo and settings files with guides:

A working version of Nengcoin explorer is at:

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
base diff reset to low overnight. Another boom for USB ASIC solo miners, probably over for GPUs.

My USB ASIC moonlander2 crashed overnight, missed this fun part

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.

Code:

python main.py --interval 10 --cpu 6

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:

Code:

ASIC/GPU miners got stuck for 244 seconds
ASIC/GPU miners got stuck for 259 seconds
ASIC/GPU miners got stuck for 275 seconds

The correct printout should be every 10 seconds:

Code:

ASIC/GPU miners got stuck for 244 seconds
ASIC/GPU miners got stuck for 254 seconds
ASIC/GPU miners got stuck for 264 seconds

The fix

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 !!!!
BACK UP and ONLINE

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.

Metcalfe's law on value of Nengcoin and Cheetahcoin
Metcalfe's law states that the value of a telecommunications network is proportional to the square of the number of connected users of the system (n2).

Metcalfe's law on value of Nengcoin and Cheetahcoin for me is the number of full nodes on the network, how many users and traders and miners and hodlers, and wallet addresses. Probably two metrics, how many wallet address and full node on the network are main metrics. Full node count is likely to be the most obvious for the success. The value will skyrocket when we scale up.

Nengcoin and Cheetahcoin, bitcoin on mobile phones, a heaven for USB ASIC miners, litecoin and dogecoin on steroids.

My current estimate for both Nengcoin and Cheetahcoin is that full nodes count on both coins are around 100 to 200 full nodes. Long term goal is for both NENG and CHTA to have more full nodes than ethereum, which has 10,000 full nodes around world with $200 billion USD market cap. Short term goal is for 1000/2000 full nodes with rocket price discovery going up. As full node counts sky rocket, both coins should moon on price in 2021!

Nengcoin Hit All Time High Price (USD) on 3/12/2021

There were heavy buying Nengcoin/Cheetahcoin over past two days. By our account, Nengcoin (NENG) price hit all time high on USD term.

Data source

(1) NENG/DOGE trading price was obtained from ShorelineCrypto exchange database raw data, published here:

https://github.com/ShorelineCrypto/shoreline_lt_chart

Using Rstudio, the raw daily trading price/volume can be sorted in Rstudio to find the highest trading price.

(2) DOGE/USD price was obtained from yahoo finance as excel sheet download.
We used DOGE/USD closing price as the daily price for calculation. https://finance.yahoo.com/quote/DOGE-USD/history/

Result of Highest NENG/DOGE price in History

Sheet manually calculated in LibreOffice as shown below, the old all time high trading price on USD was on 08/09/2019 with 539 million daily trading volume at high price of 0.00039 DOGE price. Because dogecoin price rose significantly already over past 2 years, on USD term, today (03/12/2021) NENG price is highest at 2.744E-06 USD, almost 2.4x times more on USD than the peak price of Auguest 9, 2019 for NENG.

Currently many pools are on old chains. As far as I am aware, only Cminors and spools.online are on correct v1.6.x chain:
https://spools.online/explorer/NENG

Note: note that spools.online just did a wallet refresh from beginning, so it is on old blocks, catching up.

Below is also online for reference, the explorer has not updated to latest block, but the web site should show a shaddow how much blocks number total, how much nodes connected, that can be a guide. Also below difficulty on menu is correct difficulty currently.

Nengcoin has successfully Hard Forked on Block Height with Shallow Reset

Nengcoin (NENG) has successfully hard forked on block height 2655921. The last block that old wallet (v1.5.x version) can sync with v1.6.x is block height 2655920.

Please also note that after the hard fork, effectively Nengcoin had a shallow reset to diff = 0.00244. This is another boom for USB ASIC/GPU solo miners. The shallow reset is purely caused by hard fork, not a common type of reset we saw before.

See below block hash details on the hard fork:

For the reset yesterday, I mined 220k NENG on my GPU solo mining setup, GTX 1050 Nvidia card. USB ASIC, moonlander2 on two rotating nodes setup mined total of 1.98 million NENG on this reset.

One day after this reset, which was today earlier NENG had another reset. Two resets in a row. This second reset was shallower, I did not mine GPU, only on USB ASIC. My moonlander2 solo mining on two rotating nodes mined another 1.24 million NENG today.

Yesterday was almost 2 million NENG, today more than 1 million, two days in a row, together more than 3 million NENG mined on my small USB ASIC solo rig with only 3.5 Mh/s hash rate.

Nengcoin v1.6.0.4 Released - Linux Devices on Arm

Nengcoin v1.6.0.4 released with hard fork at block height 2655920. This release is mainly for those arm linux devices such as Raspberry Pi or cloud VPS on arm cpus. The Ubuntu 18.04 on arm64 or armhf is particular interesting as it has an option to compile boost library from source to fix any hardware related issues.

Linux on Arm device wallets Arm (armhf or arm64):
https://github.com/ShorelineCrypto/nengcoin/releases/tag/v1.6.0.4

This is major release and all new and existing NENG members are required to upgrade wallet. The old version of wallet will not sync at the first cheetah block after block height 2655920
