NewEnglandCoin  v1.2.0

released at github:
https://github.com/ShorelineCrypto/NewEnglandCoin/releases/tag/v1.2.0

New Features:

• Blockchain hardfork at 273501 block
• Anti-51% attack feature enabled at fork
• Anti-instant mining enabled at fork

v1.2.0 implemented new dynamic hashing algorithm II as explained in technical whitepaper v1.0.  This new wallet upgrade is required for all users.

[honglu69]

400 blocks to go before the fork.  It looks that the fork will happen in early morning of Feb 17 New England local time, or U.S. Eastern Time.

[honglu69]

trading and wallet are offline in ShorelineCrypto exchange because of hard fork.  They will be restored after successful hard fork.

NENG block chain has successfully forked off  at 273501 height with time stamp of Sun, 17 Feb 2019 16:56:44 GMT, below block.

Below is the first forked block link
http://nengexplorer.mooo.com:3001/block/c0c58a22ec247f47347b875592688eb0253b06bb8fcc89a7fa8c17e8d58ab583

Research on verifying the results of dynamic algorithm II  is ongoing.

v1.2.0 Hard Fork has been major success!

Research on first forked 50 blocks confirmed that shortest block time was 4 seconds.  Essentially fast block time or instant mining has been stopped.  Historically, fast blocks would
be 1 in 20 blocks , some times 1 or 2 blocks within 10 block stretch.  The dynamic diff algorithm implemented in v1.2.0 is working.

Of the first forked 50 blocks, 17 blocks were mined by CPU miners,  33 blocks were mined by ASIC or GPU miners.  In other word, the first 50 blocks under new algorithm, ASIC/GPU miners got 66% of total rewards, CPU miners obtained 34% of total rewards.  Ratio split on ASIC/GPU/CPU miners are not constant, could be subject to changes depending the difficulty and mining rigs distribution.  However, this 66/34 split of rewards is within expectation of our original plan for the v1.2.0.

ShorelineCrypto trading/wallet are back to normal on NENG.

looks like we found the hardfork block our pools are mining as usuall

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.

Found one issue after the hard fork,  the original plan was to raise the spike difficulty level within 3 seconds to the level of dogecoin.   The current dogecoin difficulty is about 2 million,
litecoin difficulty is about 7 million.

However,  the v1.2.0 math is off by 10x.  My mistake. The spike difficulty is only 1/10 of dogecoin level. Here is screenshot I obtained on the small ASIC rig that we ran.  Below screenshot is from  either Findblocks or Miners.rocks pool. We actually tested on both pools and got similar screenshot like below:

https://ibb.co/k0xYgGT


Note in the screenshot, the mining pool said "Network difficulty changed to 244k".    The desired result is 2440k.  
ASIC mining pool should set difficulty to the base level, which is 16 or 25 whatever, probably several orphaned blocks got ASIC pool confused and used the 3 seconds spike difficulty instead.
Whatever, this tells us that the spike difficulty is only at 0.2 million level,  one tenth of dogecoin, or 3% of litecoin difficulty level.

On the otherhand, NewYorkcoin  current mining difficulty is  928.  The NENG spike difficulty is 263x larger than that of NYC.  This issue is not so urgent to fix.  We will table it for now
and do a bundled security upgrade in 2019 Q2 together with other issues TBD.

no worries when you have updated the source give us a shout and we will update

It appears that now it is exclusive mining period for ASIC/GPU miners.  There are probably no rewards for CPU miners for now. Not sure why.  Still learning and studying the NENG blockchain.

The ASIC miners got stumbled into 244K zone, thinking the difficulty base level is 244,000.  Actually big pool ASIC miners are not doing so well, Blocks are mined by big ASIC for sure, but not that much rewards.

The big winner now is small solo ASIC/GPU miners.  I actually now am running a small ASIC USB stick at 3 Mh/s hash rate, getting blocks virtually very two minutes. Probably true if someone runs a GPU solo miners for similar results with big rewards.  For this period,  the v1.2.0 is encouraging small ASIC/GPU to go alone with solo mining setup.  

[honglu69]

Update on solo-mining small ASIC rigs:  gave up on solo-mining setup messing.   Only good for couple of hours and then were hit with "all pools are dead" error.  
Not worth the effort.     

Re-join the two pools here at NENG.

[honglu69]

One Major Issue found on v1.2.0 ,  for unknown reason,  as soon as ASIC miners stumbled into 244k difficulty zone,  NENG is no longer CPU minable.  virtually 100% of mining rewards go to ASIC or GPU miners,  pool or solo miners.

Because CPU mining feature of NENG is important coin feature. This is major issue.  We will give a day tomorrow to observe NENG blockchain movement and work on the solution.
Until further notice from here, it is not worth trying Cheetah CPU mining for now because pretty much 100% of rewards goes to ASIC or GPU miners.

CPU mining were back just minutes ago.  This was likely to be difficulty reset period.  It used to be super fast movement, 1 second per block for ASIC miners for 1440 blocks.
Because v1.2.0 upgrade removed instant mining, the reset took much longer to the point of slow movement on very low diff.  

But now the base diff is up so that CPU mining is back into play.

I started mining this coin about 14 hours ago, using a Rock64 (had to use a modified 'atomic_pointer.h to compile for the ARM processor) and have mined 21 blocks so far.

I just want to be sure I'm on the correct chain... block number and nethash matches the explorer listed in original post:

    "blocks" : 275437,
    "currentblocksize" : 1000,
    "currentblocktx" : 0,
    "difficulty" : 0.00024414,
    "errors" : "",
    "generate" : true,
    "genproclimit" : 4,
    "hashespersec" : 4093,
    "networkhashps" : 12837,
    "pooledtx" : 0,
    "testnet" : false

Networkhaskps seems rather low... and looks to be continually dropping.

Also, does a "miningprivkey= " entry in the .conf file work the same as other bitcoin derived alts (to mine to one address)?

Edit: should have included version - is this correct?
    "version" : 80705,
    "protocolversion" : 70002,
    "walletversion" : 60000,
