Hi, here the wallet is not syncing, can you send the nodes or the conf file?

Thanks

The bad nodes are attacking the network. Still not giving up. Make sure to update to v1.2.1 wallet and CPU mining with cheetah.

I updated the wallet and then the wallet does not sync anymore. I can not mine because the wallet does not sync.

Fixed issue. The seednode that ShorelineCrypto operates was shut down by cloud provider due to billing payment issue. The issue was resolved and seednode is up.

Loss of seednode plus the.bad node not giving up was cause of network problems. Now all should be good. Mining is normal on my side.  The bad node is still there but it won't  affect mining or anything else

[honglu69]

My wallet shows that "out of sync" zero hour behind. But mining is normal. Ignore the out of sync as this is mainly that bad node still has 300 blocks longer, not giving up.  The wallet and network are fine.

Before I updated the wallet, I sent some coins to the shoreline, the wallet appeared as a validated transaction, but the coins were not credited to me on the shoreline. Then I updated the wallet and can not synchronize more, and if I leave mining with the cheetah, he never stops mining, he keeps mining all the time and I do not even know if I'm finding anything. For txid I did not find anything in the block explorer, but the coins left my wallet and I do not know where they are.

Try to search the block chain explorer for the transactions:

 Hard Fork was announced for software release 1 week before the event actually happened, 1 month and half after whitepaper v1.0 was announced on this.  Anything mined in old wallet version after hard fork is no longer valid, waste of energy.  There could be 10 to 20 blocks compatible after fork with old wallet, but not likely to be more blocks than that.

You can re-sync the chain with new version of wallet software on the same backed up wallet file.  Make sure to back up wallet file first.   Those mined coins after fork will be gone if  you were mining the dead chain.  Old wallet file is always good to use up to the fork.

Updated current "getpeerinfo" from my wallet, in case some one needs to do "addnode" for IPs to sync the wallet with good nodes:


Good nodes out of total 16 peers, bad nodes manually removed by myself



"addr" : "206.189.113.92:6377",
"addr" : "97.73.84.138:37036",
"addr" : "217.9.123.38:57879",
"addr" : "84.59.246.89:54293",
"addr" : "196.52.2.116:64279",
"addr" : "217.9.123.38:65528",
"addr" : "76.70.51.130:50781",
"addr" : "76.70.51.130:58690",
"addr" : "81.191.6.111:45699",
"addr" : "104.129.6.156:38008",
"addr" : "212.56.109.179:55000",
"addr" : "76.70.51.130:38750",


To addnode in order to sync wallet better, do this in GUI wallet  click HELP -> Debug Window -> Console , 

one example type in below commands manually for one IP, do it for several node IPs until wallet is good at syncing:

Code:

addnode 76.70.51.130:38750  add

Update on v1.2.1 new version mining situations now:

I do not have thorough research on distribution of mining rewards, just few observation and a guess, which most likely to be close to truth:

Break down of big ASIC miners vs  small ASIC/GPU  vs CPU miners

 Right now the winner is small ASIC or GPU solo miners.  My guess is that today
50% of blocks were mined by small ASIC solo miners or GPU solo miners.   This group of miners are big winner today.  This is unexpected in that the new algo is much more
big ASIC resistant than I originally thought.  

big ASIC or big POOL miners probably gets 30% of blocks mined now.

CPU miners may get 20% of total blocks mined for now.  


Previously  Dynamic Diff v1.1.x was never friendly to small ASIC or GPU miners. It was either big ASIC or CPU miners.  Now things changed dramatically on the mining situation of
NENG blockchain.  This change of trend was expected in whitepaper design. But the degree of change so far exceeded original plan.

[honglu69]

For the first time tested out GPU solo-mining.  Just find out that GPU solo-mining now can make killing on NENG block rewards, getting blocks pretty much very 10 seconds.
Actually GPU solo mining is much better than even small ASIC USB stick mining.  Small ASIC probably only get one block per two minutes.

The breakdown of three groups really should be GPU/CPU/ASIC.  Now is the time for GPU solo miners.  Added "GPU mining" in the title of this thread.

[krypton93]

really my asic L3+ produces very few blocks! but mining cpu I got for 8 hours 400 + blocks

Congrats. Just checked my 2 core Linux running cheetah for 17 hours, mined 9 blocks.  I thought CPU were not doing well, you scooped almost all!

Dev Policy on Checkpoints on NewEnglandcoin

NewEnglandcoin v1.2.1 update is checkpoints security upgrade to secure the blockchain on hard fork.  Checkpoints technique is controversial method in blockchain world.
In fact, bitcoin itself has not performed checkpoints for a long long time.  The issue with checkpoints is that decentralization of  a coin means that nobody has central control on blockchain.
Certainly NENG dev does not intend to control NewEnglandcoin blockchain and merely view ourself as tech support.  However, frequent checkpoints on a coin means the coin is centrally controlled by dev team.

In order to fulfill decentralization goal of NewEnglandcoin, we as dev do not plan to frequently apply checkpoints technique.  We only intend to apply that on hard fork in the future.
Even for hard fork, we do not intend to impose our forking view by ourselves.  Any future hard fork will have several weeks to a month of pre-annoucement on hard fork in bitcointalk or discord for the intention.  We will also issue release of new software version one week in advance in order for members to prepare fork. The new release will have 1 week compatible blockchain with older version and will have fork a week later.   Therefore, 1 week to 1 month time will be available for NENG members to express any opposing opinions on fork, and there will be minimum of 1 week period to allow DEV to cancel or modify hard fork plans in the future.   We believe such procedure in place on NewEnglandcoin  from now on will surely confirm that
any future checkpoints on hard fork is not indication of any centralization.  NewEnglandcoin will continue to be a decentralized cryptocurrency and controlled by nobody just like bitcoin, litecoin or dogecoin.
  
The next hard fork or potentially a checkpoint on NewEnglandcoin will be Q3 of 2019, to be determined by our research on the results of v1.2.x release.

The wallet "out of sync" warning should be gone for now.  The public chain block length is already longer than that of bad nodes.  Here it is from my wallet getpeerinfo command,
This is one of the bad node with 284124 blocks:
{
"addr" : "51.77.116.183:6377",
"services" : "00000003",
"lastsend" : 1550891119,
"lastrecv" : 1550891119,
"bytessent" : 13018,
"bytesrecv" : 146422,
"blocksrequested" : 8,
"conntime" : 1550888808,
"version" : 70002,
"subver" : "/Satoshi:0.8.7.5/",
"inbound" : false,
"startingheight" : 284124,
"banscore" : 0
},

The current block explorer length is 285338.

Interesting mining estimate from Rocks Miners pool:
http://miners.rocks/site/mining
     Name             Amount           Diff    Blocks     TTF***    Hash **   Profit
  NewEngland (scrypt)   20000 NENG   244.137 k   289 913   9 months   44.7 Mh/s   0.00000


*** is  estimated average time to find a block at full pool speed

TTF is 9 months at 244k difficulty at 44.7 Mh/s hashrate.  This is spike difficulty for NENG on the first 3 seconds.  It would take 9 months for this hashrate to find one block.

[krypton93]

in all pools shows the difficulty  244.137 k  and Net Hash 10-40 Th/s ! and why such errors?

[honglu69]

in all pools shows the difficulty  244.137 k  and Net Hash 10-40 Th/s ! and why such errors?

DynDiff on scrypt is new algorithm.  I think pool software only assumes the traditional scrypt algo, not this DynDiff.  


10-40 Th/s is probably exaggeration of actually hashrate on NENG.  It can not be that high.  On the other hand, the explorer says only 2.8 Mh/s total network hashrate, this is also exageration on the low side.  The total hashrate on NENG is probably significantly more than 2.8 Mh/s.  In the recent past before the v1.2.x upgrade hard fork, the total hashrate was in the range of 1 G h/s to 2 Gh/s.  There may be more GPU miners now. But still I think the network hashrate probably still in 1 to 2  Gh/s

Good evening, what is and where do I find "rpcuser" and "rpcpassword"?

Thanks

In the cheetah software folder, there is file named "newenglandcoin.conf-example",   renamed it to "newenglandcoin.conf",

use an editor to modify it, windows would be "wordpad",  in mac, not very familiar, maybe macedit  or  TextEdit?

Change the first two lines of the files to a more personalized randomized rpc password / username:
-------------------------
rpcuser=dfas7860
rpcpassword=Fdsf9er9wqr90Fdf
--------------------

Do not use my above example,  just  type in some random charaters + numbers for username/password so that only you know them.  

The miner works in other coin too or only in NewEnglandcoin?

For now only NewEnglandCoin. If more coins adopt similar dynamic diff algorithm , the miner could support more in the future.

At this moment ,. CPU miners probably takes 5% to 20% of total block reward, averaging about 10%. Majority of blocks reward still go to ASIC miners.

If this is mined by ASIC miners, does it even make sense for anyone else to compete with that specialized mining hardware?

Please check out the whitepaper v1.0.  Our recent research on 50 blocks after fork confirmed that CPU miners (window, linux or mac desktop/laptop miners) obtained 36% of block rewards, ASIC only mined 66% of block rewards.  CPU mining rewards are significant.

And what is the reason for that? Could this be overtaken by ASIC miners any time if there were enough ASIC miners used to mine this?

No,  DynDiff on scrypt is ASIC-restricted.  This algo does not ban ASIC, and we welcome ASIC, but ASIC will do and is doing poorly on mining NENG.  Currently the dominant mining rig is GPU, followed by CPU or ASIC.  I do not have full data of research to back this, but my estimate is that currently 50% blocks are mined by GPU,  30% by ASIC, 20% by CPU miners.  I will publish a new research addressing your question if significantly more ASICs joins NENG in the future.  In short, no,  not even big ASIC miners from Litecoin/Dogecoin can overtake NENG now at my quick calculation. Not worth it, too costly is the reason.

Actually the big ASIC miners do very poorly,  only the small ASIC rigs are OK and are doing better.     krypton93 already mentioned that his asic L3+  only getting a few blocks while his 4-core CPU mined 400+ blocks.

The reason of this was explained in white paper v1.0.  In nutshell,  ASIC miners have weak points, they are like lions, slow moving, powerful. but Lions can not run fast, can not climb trees.  Same logic, DynDiff explored the weak point of ASIC and restricted ASIC mining rigs in this new update.

Community member krypton in discord recommended a bounty for redesign for graphic logo and he is willing to donate large sum of NENG for the bounty.  This community based graphic design project is still at early stage.  All are welcomed to comment here or in DISCORD.  

Just a clarification from dev point of view.  We certainly welcome any effort on the graphic and we are certainly expecting at some point community will take over the graphic design part.  Once a really good design comes along in the future, the new logo can be incorporated into future releases.

Hi, can you talk to Probitex for them to do the hardfork?
They have not done it yet and the deposits are not being credited to the accounts there.
Thank you
