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.  

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:

https://github.com/ShorelineCrypto/electrumx

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:


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.

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.

Greetings,
n 

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

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:


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:



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.

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.

Spike Block Mined at Height 3792223
A spike block at difficulty = 122k was mined at block height    3792223, 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 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.

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.

Spike Block Mined at Height 3760350

A spike block was mined at block height = 3760350 with difficulty = 122k.  explorer URL:

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.
