NENG base diff just reset, boom for GPU/USB ASIC miners
NENG base difficulty just reset to close to zero. Another boom for GPU/USB ASIC solo miners

base diff shallow reset, boom for USB ASIC solo miners
base diff just did a shallow reset to 0.044 earlier today. This is too high diff for an average GPU solo miners. But this is boom for USB ASIC on solo mining modes such as Futurebit Moonlander2 USB on two rotating nodes.

cheetah_cpuminer v1.3.0 released - fixed timestamp attack
This new version is released at cheetah_cpuminer at:https://github.com/ShorelineCrypto/cheetah_cpuminer

This new version of cheetah_cpuminer allows all cpu miners on android phones, computers, chromebook tablets to get a share of mining rewards when a big CPU miner attacks NENG with timestamp.

If your computer, chromebook, android phone already has a version in running, you can do below to upgrade:
(1) kill your cheetah CPU miner
(2) delete old cheetah_cpuminer software, re-download software
(3) restart cpuminer as before.

For android phones or linux, you can do below as easy upgrade using git command:
(1) step one: Ctr-C to kill the running cheetah_cpuminer

There is one big CPU Miner timestamp Attack


There is one big CPU Miner timestamp Attack
It appears that there is one big CPU miners doing timestamp manipulation and trying hard to monopolize all the NENG mining rewards. It appears it trying to stamp 2 minutes ahead and then 2 minutes behind and getting a lot of block rewards, driving out other CPU or ASIC miners.

Timestamp attack happened on GPU or ASIC miners before. CPU miners attack on timestamp is new on NENG. Cheetah_Cpuminer software will do a big upgrade tonight to address this unfair mining competition issue.

Can you come over to discord "support" board for help?
Most likely there is something wrong in your android procedure, for example, wrong platform (arm64 vs armhf),  or you are running on wrong dictory folder path.  Also post some screen shot of your phone UserLand app commands for that.

Hi, I'm trying to mine on android, but I couldn't execute this command (d. ./nengcoind (create wallet folder & files)), when I type ./nengcoind the message "No such file or directory" appears
Can someone help me?

For local wallet,  NEWE wallet file and NENG wallet files are compatible.  Also data files are identical too.  Just renamed backed up NEWE wallet file drop "wallet.dat" into wallet data folder.

Use the guide in wallet "upgrade_newenglandcoin_wallet.txt" when you download windows/macOS/linux/android new v1.5.x wallet and do the upgrade.

Shorelinecrypto Notice

12/21/2020
Nengcoin (NENG) is listed at exchange.  The last free trading day for old NewEnglandcoin (NEWE) will be Dec 27, 2020. After that up until TBD date in Jan 2021, only withdraw is allowed on NEWE. NewEnglandcoin (NEWE) will be delisted from exchange in Jan 2021 TBD date.


12/20/2020
Because of name change, exchange is not able to automatically convert NENG  to  Nengcoin balance at exchange accounts. What we will do is to list two coins soon next week:  one is Nengcoin with symbol "NENG", The old NewEnglandcoin will switch symbol to "NEWE".  NewEnglandcoin will soon disable trading at exchange and only allow withdraw to your Nengcoin wallet. A some point TBD date, NewEnglandcoin (NEWE) will be delisted from exchange and only leave Nengcoin (NENG) trading at exchange.

When deposit or withdraw NENG (either NewEnglandcoin or Nengcoin), please limit each transaction to 50 million NENG only and do the next transaction after exchange balance is settled first so that our software automatically handle deposit/withdraw without human support.

GPU mining rewards count on reset
GPU solo mining NENG is no longer profitable. I have shutting down my GPU mining.

Here is count for several hours of GPU mining NENG reward today. GPU card: Nvidia GTX 1050 card,

total NENG mined for 5 hours of mining: 2.14 million NENG. Attached is ccminer mining screen in windows 10 before I shut down mining. The ccminer block reward count is not accurate because some of NENG mining coins were orphaned:
