After this block was mined, 51% risk protection algo was triggered and the normal mining diff becomes spike diff = 122k while smaller miners on USB ASIC or CPU miners can continue mine at cheetah diff at 0.005.   A reset will come after wards most likely after the next difficulty adjustment.

At this spike difficult triggering and also the low diff afterwards, it is a boom for smaller CPU miners or USB ASIC miners while big ASIC rigs are restricted due to heavy penalty spike difficulty or  on low diff for big hashrate.

After this block was mined, 51% risk protection algo was triggered and the normal mining diff becomes spike diff = 122k while smaller miners on USB ASIC or CPU miners can continue mine at cheetah diff at 0.005.   A reset came after wards and now the difficulty = 0.006 low levels.

At this low diff, it is a boom for smaller CPU miners or USB ASIC miners while big ASIC rigs are restricted due to heavy penalty on low diff for big hashrate.

With this spike difficult hit at low diff,  a special 51% attack protection mechanism is triggered and normal difficulty will become 122k.  The cheetah diff still remains at difficulty = 0.005 after 2 minutes wait.

sounds like a bloody joke there, right?  well,  you can re-vive now with new version v2.3.0  NENG wallet now.

I was the one builder behind the upgrade among the others from my domiciliary state but everyone got stabbed to death. Only I remained, the lone survivor of the assault that a stranger in meta horror mask carried out on all of us in the middle of pitch black night in moto hotel in south nebraska. That poopy-shlocky wallet 2.0.0 made by me was a jokish flashback to my coding past. It does not sync. I made it out of my sense of snobiety.

Nengcoin v2.3.0 Released - Hard Fork on Height 3800810


This is Nengcoin core hard fork release on version v2.3.0 for all users and miners with full Version tag "v2.3.0.0-randomSpike-1.12.x".  This is major release with hard fork and soft forks so that all miners/users are required to upgrade to new version wallet.

This new version v2.3.0 will fork on first cheetah block after block height 3800810 for sure. The new release also includes future timestamp limit change and CSV soft forks so that the fork from older version may start on non-cheetah block after block height 3800810.   The hard fork event is projected to happen in 3 weeks in late June, 2022.

Nengcoin v2.3 Hard Fork Proposal, Electrum Wallet/DEX

Nengcoin v2.3 Hard Fork Upgrade Proposal

Here we announce that the new coming nengcoin core software release will be on v2.3.0
version with full version tag in wallet “"v2.3.0.0-randomSpike-v1.12.x". This new release will be
expected to have hard fork and also soft forks with extra BIPs. The main purpose of this new
release is to support ongoing dev work for atomic swap based native DEX trading
(AtomicDEX/ShibaDEX) as well as improvement on security against timestamp/DUST
attacks.

* State of Mining on Nengcoin across Multi-rigs
* DEX – Ideals of Freedom, Decentralization, Censorship Resistance
* Update on Dev Progress on ShibaDEX and Electrum Wallet
* ROOT CAUSE of Electrum Error - BIP68/BIP112/BIP113
* Rational for Proposal to Activate 3 Soft Forks
* Electrum Wallet versions: Old vs New
* NENG Dev Roadmap Changed: Light wallet, Hardware Wallet
* NENG Lightning Network – Open Minded, Revisit 2025
* Hard Fork – BIP34, Future Timestamping Rule

NENG has been on reset since yesterday.  low diff for a while.  Probably a feast for direct CPU miners on solo setup.    Android phone should stick with cheetah_cpuminer to avoid overheat.
from miningpoolstats page,  77% mined by unknown sources,  23% mined by ASICs  on diff = 0.0076.  A feast for direct CPU miners on PC Mac of Pi4 now,  not truly that much for android.

v2.2.0 Review, DEX Comparison, Dev Update on Light Wallet, Atomic Swap
4/18/2022
Hong Lu
Dev of Nengcoin & Cheetahcoin


NENG v2.0 release rebased Nengcoin wallet to litecoin v0.13.3 core fork with new features from 3 BIPs.  NENG v2.2 hard fork defeated the 2nd 51% attack and restored lost coins to SouthXchange wallet successfully.   v2.2 also cut cheetah difficulty 8 times to improve CPU mining and reduced block bitcoin future 2 hours timestamping rule to 2 minutes rule to reduce timestamp attack risk.

So far NENG v2.2 has been running smoothly for more than 2 months and all signs indicate that this core wallet release has been quite successful. 2 out 3 BIPs  (BIP66 BIP65) are already activated,  the remaining BIP34 is on the path to be activated at block height 3.9 million in a few months. CPU mining for android phone on "cheetah_cpuminer" has been back for regular android phones or on computers.  In fact,  due to other issues like DUST attack on CHTA side,  dual miners of android phone on both CHTA/NENG mainly mine NENG in recent months.  It used to be that CPU mining CHTA was much more profitable,  now it is reversed.  This could be another topic mainly on Cheetahcoin side, but for NENG, things look good on CPU mining side.  

Part of new wallet v2.x version was for Atomic Swap style native  decentralized exchange (DEX) opportunities for Nengcoin.  Instead of semi DEX with wrapped token (WNENG),  native UTXO coin Nengcoin have many DEX options, we mainly surveyed and studied three options in deep dives:

(1) Thorchain
(2) AtomicDEX/ShibaDEX
(3) Block DX

Thorchain

Thorchain is most recent entry on UTXO coin native DEX market.  Thorchain supports BTC, LTC, DOGE,  no DASH yet on chaos net with live DEX trading.  Thorchain uses liquidity pool concept applied to native UTXO coins and has great potential in the long run.  It is less then one year new tech and the mainnet is not launched. The chaosnet of Thorchain has limitations imposed and it is invite-only for new coins listing.  We do not believe Thorchain is interested in supporting tiny cap coin like Nengcoin yet, fee or no fee in near term.

Block DX  

Blocknet based Block DX DEX technology has been around for many years. This is the first DEX tech that we tested and studied late last year initially. Besides all the positives beind this DEX technology,  this DEX appoach does have short comings. First, DEX listing cost is not that cheap.  Technically listing new coin at Block DX is free, however, to have functioning DEX trading, a minimum service node is required for Nengcoin and one service node cost $2000 USD to $5000 USD depending on Blocknet trading price.   The more troubling factor on Block DX is that this DEX is least popular among the 3 we evaluated.  Cost of listing new coin is one issue,  less traders and less trading liquidity is another major problem.
 
Worst of all,  Block DX trading volumes are largely untracked at major crypto tracking sites such as coin market cap, coingecko or coinpaprika.

AtomicDEX/ShibaDEX

dogeDEX now renamed into ShibaDEX, which is open sourced unrestricted DEX for U.S. Canada users.   ShibaDEX essentially trades at same market as AtomicDEX and uses same private keys as AtomicDEX wallet.  Essentially they are all the same DEX offered to different countries.

AtomicDEX/ShibaDEX are quite popular with many trading volume ongoing daily.  AtomicDEX trading DEX activities can be found at coinparika. ShibaDEX essentially offers two things to its users:  a light wallet that own your own private keys,  a DEX trading opportunities against BTC LTC DOGE DASH BNB or KMD with no KYCs.  ShibaDEX charges no fees on its Desktop wallet/DEX for new coins listing there.

We have concluded and decided to focus our dev activities on ShibaDEX for Nengcoin future DEX new listings.  ShibaDEX does require that each coin dev team maintain and provide an ElectrumX Server because ShibaDEX wallet is just a light wallet implemented on top of open sourced electrum wallet technology.


Dev Work on Electrum Server/Wallet

 We have started dev work on ElectrumX server and wallet work as required for AtomicDEX/ShibaDEX new coin listings.  So far so good,  an electrumX server has completed on code and running at ShorelineCrypto internal server.  

The  electrum work and  DEX listing work is not quite easy, not expected to complete soon.  But we will update NENG communities on progress as times go on following our published dev roadmap.

Syncing should be much easier and faster now on the latest v2.2.0 version, no need for snapshot.  Just download latest version and sync.

Recommendation to SouthXchange on Deposit/Withdraw Issues

Date: 3/2/2022


Dear SouthXchange Support,

I am representing a group of Nengcoin community leaders of Devs/Ambassadors to write you
this recommendation letter. We are recommending to reopen Nengcoin (NENG) wallet deposit
and withdraw at your exchange with new security considerations. Specifically we are writing to
recommend 2000 block confirmations requirement on Nengcoin wallet deposits and no limit on
withdrawals.

For full text of this long letter on the rational of security from NENG leadership behind this recommendation:

Emergency v2.2.0-randomSpike_1.11.x Released - Hard Fork on Height 3539301


This is emergency hard fork release on version v2.2.0 for all users and miners.  There was double spending attack on NENG wallet at SouthXchange on 2/12/2022 that stole 3.75 billion NENG.   v2.1.0 hard forked right before the attack block height.  However,  the v2.1.0 fork release was public before SouthXchange was able to secure and recover the stolen coins. Those Hacking withdraw were later confirmed again in the new v2.1.0 chain on Feb 18,2022.

This new fork v2.2.0 on block height  3539301 will fork before the hacking transaction block height in new chain.  This fork was also collaborated between NENG dev and SXC tech support so that SXC was able to recover and transfer those 3.75 billion NENG in this fork into new wallet, and confirmed in new chain before we release this fork public. SouthXhchange support has been very helpful and patient with us and worked with NENG dev for an almost 1 full working day to get this done and confirmed.

Cheetah diff was raised by 5% just for cosmetic reason to have fork from v1.10.x prior old chain.

You may have to do "-reindex" to fully sync this hard fork to roll back to Feb 18 to the hard fork block height.

Compensation for Honest Miners

Because this release hard fork happened 4 days before release date, some honest miners will lose coins on this hard fork.  Please contact RedRaider10 at discord for compensation arrangement from team.

do not use "cheetah_cpuminer" exclusively for mining. I mine phone with "cheetah_cpuminer" because I do not want my phone overheat. But my main PC is mining directly in wallet with just "setgenerate true"  or "setgenerate true 4"  (using 4 CPU to mine).  The regular difficulty is lower than cheetah diff,  so ASIC is not catching up yet, a lot of coins can be mined directly, better than ASIC because of randomSpike restriction imposed.

CPU miners now have two ways of mining NENG,  regular difficulty or cheetah difficulty.   ASIC only have one way, regular difficulty.

How to CPU Mine NENG without pool
currently the blockchain is moving fine, however, pool nodes are still probably -reindex, not catching up with new hard fork yet.

Because currently there are no pools supporting NENG now. CPU mining is main mining method , in wallet "setgenerate true" will mine regular diff = 0.000244, the "cheetah_cpuminer" will mine cheetah diff = 0.00488 after 2 minutes wait.

For those who do not know, follow this old bitcoin youtube video for exactly the steps:
https://www.youtube.com/watch?v=Xd4Opw0Upok

For 8 core PC with 8 CPUs, recommend to use 7 CPUs for mining, leaving one CPU idle for wallet syncing and other stuff with below command:

Update on 2/19/2022 ,

Now the regular diff is above cheetah diff, but CPU mining method still can be done if PC or Mac is powerful enough. Not recommended for phone due to overheating issue. For phone, stick with "cheetah_cpuminer" method.

Emergency v2.1.0-randomSpike_1.10.x Released - Hard Fork on Height 3536501


This is emergency hard fork release on version v2.1.0 for all users and miners.  There was double spending attack on NENG wallet at SouthXchange on 2/12/2022 that stole 3.75 billion NENG.   This hard fork will orphan that double spending, and make those 3.75 billion NENG stolen coins orphaned because the hard fork happens right before the attack block height.

This is also a planned regular hard fork transferring the knowledge of security upgrade from recent Cheetahcoin v1.10.x hard fork release to address timestamp attack.  The timestamp risk on NENG have been similar and the bitcoin 2 hour rule is now changed to 2 minute rule on this release.  Other changes:

(1) cheetah difficulty dropped 8 times to improve small solo miners of CPU / USB ASIC user experience and reward level. Because we know now the timestamp attack was more of ASIC attackers, cheetah diff is no longer required to hold at high diff level.  This will improve reset reward for solo USB ASIC miners too.
(2) spike diff cut in half to 110k.
