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.

 https://github.com/ShorelineCrypto/nengcoin/releases/tag/v2.2.0

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.

SouthXchange 51% Attacked on 2/12/2022

Many of you already are aware, announced in twitter and in discord, SouthXchange was 51% attacked on Sat  Feb 12, 2022, about  3.75 billion NENG was double spent and stolen at SouthXchange.  Checkout discord channel for details of info there. Very detailed including all the hacking hash transactions.

@NENGsters

Important Announcement

There was a 51% double spend attack on SXC! Trading and buying is currently disabled!

Nengcoin Leaders are working on a solution ASAP!!

Don't lose hope Nengsters!! This attacker will not win!!

#NENGcandoit!
#NENGtothemoon

I would say, based on the new error there and v2.0.0 is released,  I think the shorter chain is true chain. We are not going back to old version. It is too much going into new version now.

Soft Forks BIP66 and BIP65 are Enforced on the Chain on v2.0.0

The v2.0.0 was released 2 days ago.  The same code base pre-release  v0.13.3 was pre-released 22 days ago, that was long long time ago.

However, a timestamp attacker attacked the chain around the same day on the v2.0.0 release and v2.0.0 itself enforced BIP66 and BIP65 without BIP34 being enforced.  BIP34 is still planned at 3.9 million block height.   This is the reason for chain split because the wrong chain violated BIP66 and BIP65.  Previously we did not know that BIP66 and BIP65 can be enforced with 75% rule and 95% rule without BIP34 being activated first.

For now, we would urge for all those solo miners on USB ASIC/ASIC to move over to v2.0.0.  For those on v2.0.0 who have difficulty to sync to the same block height as block explorer, please do  "-reindex" to refresh the nodes into correct chain.

We are deciding to move over to new chain and not to look back into old versions on soft forks issue.

I think the chain split, we got the reason, BIP66 soft fork is enforced on some of the bad header blocks

One of my short chain got flipped to longer chain naturally, not by human surgery. The longer chain is true chain for now. It makes sense, it has higher diff,
longer chain,  no spike diff involved. Not sure what happened, the chain probably got split somewhere. 

Not sure what caused this. But my two nodes,  one on old v1.9.x version wallet reindex from beginning to end, and also the official explorer site node
http://nengexplorer.mooo.com:3001/

all did refresh sync from before the split, then end result is same, the correct chain is now on explorer, same as redpool/spool pool.  In other word, the shorter
chain is the correct chain.  I did see lots of headers' error in log file.  So maybe the longer chain had lots of corrupted headers and block data in corrupted format.
it was going through by some nodes,  but I think the longer chain is wrong chain.  

To verify the truth. I am going to do a third node on v2.0.0, fresh start node, syncing from zero to now. I will see the results tomorrow.

Why are there 2 chains (00: UTC  February 06, 2022) :
- PC wallet(v2.0) and http://cr2big.xyz are at block: 3 520 741
- https://spools.online and https://redpool.pl/ are at block : 3 520 034
So which chain is correct?

Pancake Swap has gouging price. I refuse to do any business with it. What is NENG? Whang-Chang jackie chan chinese toilet waste. Pop-chop tri-chop doodle-gloop coin that not even pond scum will buy. Care to change the name to a more decent? Does it exist on binance smart chain? As a market-maker guy, I lodge in my pants hefty piles of cash. I could create the future for u. But I wont.

Nengcoin v2.0.0 Released - Windows, MacOS, Linux, Android phone, Chromebook, Pi4


Nengcoin core v2.0.0 is released.  This is major release and recommended for all nengcoin users except for solo miners on USB ASIC/ASIC.  Please download new wallet here: https://github.com/ShorelineCrypto/nengcoin/releases/tag/v2.0.0


This version is rebased off bitcoin/litecoin v0.13.3 with full in wallet CPU mining capabilities.  All CPU miners on PC/MacOS/Linux/Android phone/Chromebook/Pi are recommended to use this new wallet.  This wallet is static linked binary wallet so that macOS on x86_64 or M1 chip hardware on latest or older version of OSX all should work with full CPU mining capability when it is used with "cheetah_cpuminer"  miner.

For features and issues of this version, please checkout our prior report at:

https://github.com/ShorelineCrypto/nengcoin/releases/download/pre2.0/NENG_v2.0_Upgrade_Softfork_Proposal.pdf

CPU mining domination continues close to 100%. average block is 6 minutes per block mined mainly on PC or android phone

NENG base difficulty had a reset hours ago with fast blocks. Then minutes ago, another spike block was mined at difficulty = 244k at block height 3505827

CPU miners will continue to dominate close to 100% again on NENG mining for now until next difficulty adjustment block. It could be a day or 2.
