Spike Block Mined at Height 3777093

A spike block at difficulty = 122k was mined at block height 3777093, explorer:

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.

Nengcoin blockchain Hard Forked on Height 3807405


First cheetah block was mined at block height 3807405  with difficulty = 0.0049 .  On and after this block height,  v2.3.0 is forked off from all the older versions.  
Explorer:
http://nengexplorer.mooo.com:3001/block/a4ed6ced38d8d4d3e62e3b27d1aea640558cd3dcaadbbe687bbbe78905bd6062

Older version v2.2.0 would not be able to sync after this block height.

3 CSV soft forks (BIP68, BIP112, and BIP113) locked in


today,  deployment_csv three soft forks, BIP68/BIP112/BIP113  were locked in by the BIP9 method.  To check the status change on this, you can obtain from your full node by typing below:

Code:

prompt:~/nengcoin_2.3.0_arm64_linux-gnu$ ./nengcoin-cli  getblockchaininfo

your full node command line will print out long list of status on BIPs, at bottom of the result print out, you will find this:

Code:

------skipped --------
  "bip9_softforks": {
    "csv": {
      "status": "locked_in",
      "startTime": 1656637837,
      "timeout": 1688173837
    }
  }
}

Yesterday the same command status was "started".  Today it was "locked_in"  meaning that deployment_CSV three soft forks (BIP68, BIP112, and BIP113) passed the mining flag over past 5760 blocks based on this source code of v2.3.0 version of NENG:

https://github.com/ShorelineCrypto/nengcoin/blob/master/src/chainparams.cpp#L90

Wait for another few days,  the CSV soft forks features of v2.3.0 that are required by DEX is ready to be activated on Nengcoin blockchain.

Hi honglu,

I installed the new nencoinqt, updated the addnodes and now do have 8 connections, but it still says *no blocksource available* after waiting 15 minutes.

Do you have an idea what to do?

Thanks

Make sure that you installed the correct version:  v2.3.0.   Any old versions won't sync to latest blockchain.

Yes its the new Version v2.3.0. ... thats the reason why I did install it. But I cant sync.

It shows  connections but although no blocksource. So there is a connection to the network but no syncing.

Are you behind firewall?  If you have connection 10 nodes, assuming many are on v2.3.0,  the syncing should start.

Try to add more from nodes:
http://nengexplorer.mooo.com:3001/network

probably all of them into your addnode conf file, and then restart wallet. If there is no firewall issue, the syncing should start.  

THere is one line that can help on firewall cases:

Code:

upnp=1

This works in most simple intranet.  But ISP may impose very strict  blocking that blocks all traffic from full node. When strict firewall happens,  another method may need for bypassing firewalls.

Light Wallet Electrum-NENG v4.0.0 Released


Electrum-NENG v4.0.0 is fork of bitcoin electrum open sourced wallet technology on v4.0.x code base.   Electrum-NENG wallet allows users to own your nengcoin private keys while your electrum NENG wallet can receive/send NENG coins without need of downloading full node blockchain data. 

Electrum-NENG binary wallet for Windows/macOS/Linux can be downloaded from:
https://github.com/ShorelineCrypto/electrum-neng/releases/tag/v4.0.0


Tips for Installing/Using Electrum-NENG

Some anti-virus software such as windows defender might flag this wallet as "virus, dangerous" in windows10.  This is false positive and you can whitelist this software and allow this software to run.

In "history" tab,  your transactions will be labeled as "Not Verified" even if you can see hundreds of confirmations in explorer. This is because electrum wallet first treat information from electrum server on receive/send transactions as not verified.  The electrum wallet in the background is also downloading blockchain headers and do its own confirmations locally with header information. Once the wallet header catches up on syncing,  the "Not Verified" status will go away in the future.

Sending transactions stuck issue.  If you pay too little fee from electrum, your transaction may stuck because miners refuse to mine your transactions on low fees.  You can wait for several days and the stuck transactions status will change status from "Unconfirmed" to "Local" and you can remove the stuck transaction from your electrum wallet.

Run Your Own Personal Electrumx Server

By default on auto-connect mode, there are two live NENG electrumx servers to allow connections. If you want to run your own electrumx server, please follow this repos guide to install your own server in any linux server:

First Atomic Swap Trading Success between NENG and KMD

8/28/2022


8/28 of 2022 marked first day of successful atomic swap trading on Nengcoin (NENG).   697,172 NENG was successfully traded for 0.87 KMD in a decentralized p2p fashion with no centralized exchange control, no middleman with 2 traders in full control of their own private keys.  

The atomic swap trading was performed using Komodo eco-system toolkit AtomicDEX-API and mmtools.  The atomic trading was documented here:

 https://github.com/ShorelineCrypto/coins/blob/master/swaps/NENG-KMD.md

Before this success,  several failure was encountered with various issues in atomic swap trading. Those issues were fixed and two successful trading (another trading was 800K NENG in exchange for roughly 1 KMD) was successfully completed.

The dev team continues to push forward to test current atomic swap DEX configurations.  It is expected that we will finalize and apply for AtomicDEX/ShibaDEX listing for Nengcoin (NENG) soon.

NENG/CHTA Electrum Server Connection Issue

If you are new user that never used electrum-CHTA or electrum-NENG wallet before, ignore below notice.   If you have used electrum-NENG or electrum-CHTA before and noticed that 1 or 2 of servers can not be connected, do below actions to connect to default 3 servers in auto-connect mode automatically.

Recently both electrum-NENG and electrum-CHTA two servers changed IP and ssl certificate so that existing users may find unable to connect to 2 mooo.com servers due to certificate change. 


Go to your folder below and delete old servers certificate files and then restart electrum wallet.

For nengcoin
Windows:
C:\Users\YourWindowsUser\AppData\Roaming\Electrum\nengcoin\certs
Linux or MacOS
~/.electrum/nengcoin/certs


For cheetahcoin
Windows:
C:\Users\YourWindowsUser\AppData\Roaming\Electrum\cheetahcoin\certs
Linux or MacOS
~/.electrum/cheetahcoin/certs


After deleting all the certificate files under above folders, restart electrum-CHTA or electrum-NENG light wallet, the wallet should be able to connect 3 default servers on auto mode.

Tipbot tipneng Go Live Online in Discord

Now you can tip fellow nengsters in discord with small amount of NENG easily using tipbot.  Announcement by community leader KhomradeKat | [🥇🥈🥉] (discord ID)

KhomradeKat | [🥇🥈🥉] — Today at 11:07 PM
Hello @NENGsters, some of you may be aware of @Tip Bot in the Cheetahcoin discord server. Now you can tip your fellow NENGsters with Nengcoin on Discord!

Some key takeaways:
- Please only deposit a small amount of NENG
- Sometimes the blockchain is slow and when receiving NENG, it might take a while for the transaction to go through and to see your incoming coins
- I have set the minimum withdrawal & tip at 0.01 NENG to prevent negative balance issues and exploits
- In most cases the transaction fee will be lower than 0.001 NENG
- I might work on a discord tip faucet for both NENG and CHTA
- Use at your own risk!

A few tipneng commands in discord:
check balance:

Code:

!tipneng balance

get NENG deposit address:

Code:

!tipneng deposit

tip someone 10 NENG

Code:

!tipneng <some one> 10

withdraw 100 NENG to your own address from tipbot

Code:

!tipneng withdraw <Your NENG address> 100

AtomicDEX Trading Go Live Through BitcoinZ-DEX Wallet

Fellow Nengsters,  great news today.  We have tested and confirmed that Atomic Swap based AtomicDEX trading works well through BitcoinZ-DEX wallet.  

AtomicDEX is Komodo eco-system flagship DEX for decentralized trading. There is no centralized control, no middleman and you own your own private keys before/during/after DEX atomic swap trading.  As we disclosed already,  our application to atomicDEX github through 2 pull request were approved weeks ago and the AtomicDEX/ShibaDEX desktop wallet will support NENG and CHTA trading in next binary release.

BitcoinZ-DEX wallet is another open sourced wallet that incorporated latest komodo coin commits and support NENG and CHTA now thanks to bitcoinZ-DEX dev @cipi (discord ID).  Essentially, bitcoinZ-DEX wallet share the same private keys as atomicDEX/shibadex wallet and trade in same DEX in atomicDEX.  You can download bitcoinZ-DEX latest release for linux, windows, or macOS here:
https://github.com/btcz/atomicDEX-Desktop/releases


Tips of AtomicDEX trading


(1) make sure you back up your wallet secret seed words.  If you lose your secret seed,  you will lose your coins.
(2) Trade small,  be aware of 51% attackers.  Buying or selling a couple of millions NENG or several 100k CHTA should be fine.   Bigger buy or sell amount in DEX may face potential 51% attackers.
(3)  Atomic Swap trading is P2P trading so that you need to leave your wallet open and online through the whole process. It may take half hour to 1 hour to complete whole trading.  If you are offline or computer crashed in the middle of trading, it is usually OK if you return and open your wallet immediately online after several minutes.  
(4) trading pairs are flexible and you can trade any pairs. However, we believe  KMD or DOGE pairs are most likely the most active pairs for NENG and CHTA.


Expert Traders or Market Makers

For those expert traders or market makers who prefer linux command line trading,  MMTools is great tool to use.

Tested to work well in ubuntu 18.04 and may work well in other ubuntu versions or in other linux distro too.

Nengcoin Telegram Bot Scam Settlement and New Bot Launch

11/10/2022

Hello Fellow Nengsters!

Recently discord and telegram CHTA and also NENG communities encountered a telegram bot scam where users lost their deposited coins of telegram bot.

In short summary,  a discord ID “MasterBlockDev”  entered Cheetahcoin discord channel and offered to do software development work for an android phone app.  The offer and claim was outrageous as MasterBlockDev claimed to have 6 software dev to be ready to work for our coin for as little as 70 million CHTA.  Later he also developed a telegram bot to offer CHTA wallet deposit and withdraw,  some dice/slot gambling feature and price quote feature there.  He did the same telegram bot in Nengcoin (NENG) community too later with almost identical gambling features.

A few days later, community leader discord and telegram ID KhomradeKat made a deal to purchase telegram bot code with his own pocket. Soon after, MasterBlockDev had exit scam and left discord channel and also pulled off all the wallet balance in both NENG and CHTA telegram bot wallet. This breached code purchase agreement between MasterBlockDev and KhomradeKat.  For detailed story line of this telegram bot exit scam event please visit NENG and CHTA discord channels to read comments from KhomradeKat and also ambassador discord/telegram ID LETLSkyfall. 

From Khomradekat’s count,  MasterBlockDev scammed about 16 million CHTA and 50 million NENG from both communities, worth about $60 USD as of today’s trading price.  Excluding those donation and non-user accounts balance,  15 million Nengcoin in user balances of NENG telegram bot and 8 million CHTA in user balances of  telegram bot were emptied and stolen.

Disclosure from NENG Community Leadership Team

First, let’s be clear that NENG community leadership team and @KhomradeKat personally are not responsible for your loss on your old telegram bot balance.  Be aware, “not your private keys, not your coins” crypto rule applies here.

However,  for the friendly gesture of new bot launch,  we have raised 15 million NENG donation to refund those regular users who lost balance on old telegram NENG bot. 

Community leader KhomradeKat decide to launch both discord/telegram NENG bots to serve our communities.  Currently, a new NENG telegram bot has been launched by KhomradeKat with the NENG full node wallet controled by KhomradeKat.  Dev Hong has worked with  KhomradeKat in both NENG and CHTA for a long time and is in full support of his community bot service.

How to Obtain Old Bot Scammed NENG balances

First, we can only offer refund for those regular user old telegram bot balance. We do not offer refund to those scammed donations.

For those impacted telegram bot users asking for refund,  please ping  KhomradeKat and obtain his approval first. Once the refund NENG number is approved,  KhomradeKat will notify dev  Hong (discord/telegram ID honglu69) later, and dev Hong will pay you back the lost NENG old bot balance.

The refund offer expires after 30 days from the announcement date.

Disclosure on New Bot Launch
This applies to both NENG Discord and Telegram bot that are currently managed by KhomradeKat.  Bot is for entertainment purpose only for daily dice and slot gambling fun with doge pair quick price check.  The bot wallet is centralized and controled by one person only and do at your own risk. Any future refund should not be expected as this refund on old bot is one time only event.  Miners should not mine directly into bot wallet address as this can cause serious bot wallet damage quickly.

For a more secure personal NENG wallet for investment HODL purpose, please consider a light wallet if you want to avoid heavy full node wallet syncing.  We now have many choices of NENG light wallet below that you can fully control your own private keys of NENG investments:

(1) Electrum-NENG  ---- a desktop light wallet with full GUI mouse click features. Windows, Mac, Linux
(2) Bitcoinz-DEX Wallet ----  multi-coin desktop light wallet that allows in wallet trading in AtomicDEX, Windows, Mac, Linux

ShibaDEX and AtomicDEX official wallet on current release do not support CHTA NENG yet, but will do in next release.  BtcZ-DEX wallet feels and looks like ShibaDEX/AtomicDEX wallet already with just logo change.

AtomicDEX Desktop v0.5.7 Support NENG

Fellow Nengsters,  great news today.  AtomicDEX Desktop newly released v0.5.7 official version from Komodo support Nengcoin and Cheetahcoin in its wallet and DEX for atomic swap based trading.  We have tested and confirmed that Atomic Swap based AtomicDEX trading works well in this wallet release.  

AtomicDEX is Komodo eco-system flagship wallet and DEX for decentralized trading. There is no centralized control, no middleman and you own your own private keys before/during/after DEX atomic swap trading.  AtomicDEX desktop also is light wallet supporting NENG, CHTA, BTC, LTC, DOGE, BNB, ETH etc many UTXO coins that you can hodl your coins without need of downloading blockchain full data, and without risking your coins at exchange.

AtomicDEX desktop this newest version is non-restricted version that works for IPs from USA/Canada/EU countries. Its older version used to have restriction on USA/Canada users, the restriction has been removed in new version.


You can download latest release for linux, windows, or macOS from here:
https://atomicdex.io/en/downloads/


Tips of AtomicDEX trading

(1) make sure you back up your wallet secret seed words.  If you lose your secret seed,  you will lose your coins. You can also import your old wallet using secret seed from bitcoinZ-DEX wallet or ShibaDEX wallets.
(2) Trade small,  be aware of 51% attackers.  
(3)  Atomic Swap trading is P2P trading so that you need to leave your wallet open and online through the whole process. It may take half hour to 1 hour to complete whole trading.  If you are offline or computer crashed in the middle of trading, it is usually OK if you return and open your wallet immediately online after several minutes.  
(4) trading pairs are flexible and you can trade any pairs. However, we believe  KMD or DOGE pairs are most likely the most active pairs for NENG and CHTA. AtomicDEX native coin is KMD, however you do not need to have KMD gas if you do not trade KMD pair.

For those expert traders or market makers who prefer linux command line trading,  MMTools is great tool to use.

how to set up p2pool to mine nengcoin solo?

[honglu69]

how to set up p2pool to mine nengcoin solo?

There are no good known method to do solo mining with own nodes because popular home USB ASIC moonlander2  device main software bfgminer does not support mining directly into new version of NENG solo node through RPC.


The next best thing is to do solo mode mining through pools. Setting up own private pools is difficult to do because pool work is complicated.

NENG  is scrypt proof of work coin, any p2pool setup on scrypt could be used and tested out.

Web Version of AtomicDEX Support Tech Issues

Dec 11, 2022

Komodo released an alpha  web version of atomicDEX days ago. This version works for Chrome browser as web app and works like wallet in web browser with capability of atomic swap trading in AtomicDex

However, this web version atomicDex does not support NENG nor CHTA.  Here is question asked in Komodo discord on why and how to support both coins in the future on tech level:

honglu69 — Yesterday at 12:35 AM
Web version of atomicdex wallet should work with TCP  port type of electrumx server, right?   I can not find CHTA nor NENG in web wallet, I assume is that the web wallet is using very old version of coins repos.

cipi — Yesterday at 1:11 AM
WebDEX needs WSS (secure websockets) port, including a proper SSL certificate (not selfsigned)
the ports need to be added to coins repo, like: https://github.com/KomodoPlatform/coins/blob/master/electrums/KMD#L24 (ws_url param)

WSS support for Electrumx Server Issue

WSS port (secure websockets) are not supported currently on CHTA or NENG electrumx server.  This new tech requirement from Komodo webDEX wallet certainly is interesting and nice feature to have.

It is too early stage for now, but our dev team certainly will look into this issue as part of future web wallet dev work.
