[ANN][ANDROID MINING][AIRDROP] NewEnglandcoin: Scrypt RandomSpike

New England
New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/
NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

(Updated) [Staking] Reddcoin Core client GUI wallet on a Raspberry Pi Model 3B

Intro

This thread is an update to my first Reddcoin staking tutorial that was written 7 months ago.
 
The reason for the update
My Reddcoin Core software crashed and became unusable. My Raspberry Pi 3B would lag and freeze, I couldn't stake anymore.
 
Instead of just redoing everything the same way, I wanted to see if I could improve on 3 points:

This video shows how long it takes to start Reddcoin Core.   TL;DR:
     

Extra

Backup
Backup your wallet to prevent losing the RDDs in your wallet! There are two methods to backup, do both. Make new backups if you create a new receiving address!
 
 
   
Boot with only 1 USB drive plugged in:
Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly.   If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
   
Connection issues If you have issues syncing the blockchain because you have 0 network connections, please follow the instructions in this thread.
   
Start Reddcoin Core easier
Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
   
Minimization options
Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
   
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
 
   
Chromium as browser: The updates break Firefox, the browser crashes when you try to run it. Install another browser, Chromium, to solve this issue.
   
Updates / Upgrades
If Software Updater shows up and tells you that there is updated software available, do not install the updates using Software Updater. Use LXTerminal to update Lubuntu.

Dogecoin on Linux - The Complete Beginner's Guide

I'm writing this because I couldn't find a single condensed guide on compiling the wallet and running mining software on linux, specficially Ubuntu/Linux Mint. I combed Bitcoin and Litecoin forums for similar problems I was running into and eventually got everything nailed down, so here it is in one place, for new Shibes.
If you want to make a Dogecoin directory in your downloads folder to keep things organized, you will need to modify these commands to refelct the change. So instead of going to ~/Downloads/ you will need to go to ~/Downloads/Dogecoin and be sure to put the zipped files there when you download them, but the commands will be the same otherwise.
cwayne18 put in the work to make a PPA for the QT client here.
Ubunutu/Mint/Debian users should be able to install the client with the following commands:
sudo add-apt-repository ppa:cwayne18/doge sudo apt-get update && sudo apt-get install dogecoin-qt 
To update using this method, run
sudo apt-get update && sudo apt-get upgrade dogecoin-qt 
Compiling the Wallet Manually
I suggest using the PPA above, but if you want to compile manually, here you go.
1)Download the newest source from here. If you want to check out the Github page, click here
2)Unzip the package with the native client OR, navigate to your downloads and unzip
cd ~/Downloads unzip dogecoin-master.zip 
3)Now it's time to compile. You will need to install the dependencies, just copy and paste the following code. It will be a fairly large download and could take some time. It is always important to update before installing any new software, so we'll do that first and then install the dependencies.
sudo apt-get update sudo apt-get upgrade sudo apt-get install libssl-dev libdb-dev libdb++-dev libqrencode-dev qt4-qmake libqtgui4 libqt4-dev sudo apt-get install libminiupnpc-dev libminiupnpc8 libboost-all-dev build-essential git libboost1.53-all-dev 
4)Once that is done, go to the doge-coin master directory and compile:
cd ~/Downloads/dogecoin-maste sed -i 's/-mgw46-mt-sd-1_53//g' dogecoin-qt.pro qmake USE_UPNP=- USE_QRCODE=0 USE_IPV6=0 make -j3 
After running the qmake command you will likely see some text similar to
Project MESSAGE: Building without UPNP support Project MESSAGE: Building with UPNP supportRemoved plural forms as the target language has less forms. If this sounds wrong, possibly the target language is not set or recognized. 
It's perfectly normal, so don't worry about that.
Your Dogewallet is ready to go! The executable is in ~/Downloads/dogecoin-maste and called dogecoin-qt. Your wallet information is in ~/.dogecoin. You can run the wallet at any time by opening terminal and typing
cd ~/Downloads/dogecoin-maste ./dogecoin-qt 
Future upgrades to dogewallet are easy. Back up your wallet.dat, and simply follow the same directions above, but you'll be unzipping and building the newer version. You will likely need to rename the old dogecoin-master directory in ~/Downloads before unzipping the newest version and building. Also, it is likely that you will not need to install the dependencies again.
Alternate Method For Installing Dogecoin Wallet from Nicebreakfast
After installing the dependencies listed in step 3, open terminal, then navigate to where you want Dogecoin Wallet stored and run:
git clone https://github.com/dogecoin/dogecoin ./autogen.sh ./configure make 
then when the wallet is updated just run
git pull 
from the dogecoin directory.
GPU Mining
GPU mining requires CGminer. My suggestion is to get the executable already built. The creator of cgminer has removed the built file from his website, but I've uploaded it here
sudo apt-get install pkg-config opencl-dev libcurl4-openssl-dev autoconf libtool automake m4 ncurses-dev cd ~/Downloads tar -xvf cgminer-3.7.2-x86_64-built.tar.bz2 
Don't use anything newer than 3.7.2. The newer versions of CGMiner don't support GPU mining.
That's it! You have cgminer ready to go! You will run cgminer with the following syntax
cd ~/Downloads/cgminer-3.7.2-x86_64-built/ ./cgminer --scrypt -o stratum+tcp://SERVERNAME:PORT -u WORKER.ID -p PASS 
A good guide for fine tuning cgminer can be found here; follow the litecoin example.
EDIT
I had trouble getting cgminer running with a single line command, but running it via an executable .sh file works. This is covered in the cgminer setup guide I posted above but I'll put it here too. In the same directory that has the cgminer executable, you need to make a file called cgminer.sh and make it executable. It should contain the follwing:
export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export DISPLAY=:0 find *.bin -delete sleep 5 ./cgminer 
Then you can call cgminer in terminal by doing ./cgminer.sh You will need a cgminer.conf file containing all your options. All of this is covered in the guide that is linked above.
A quick note about AMD drivers: They used to be a huge PITA to install and get working, but the newest Catalyst drivers are great. There's a GUI installer, everything works out of the box, and there is a lot of documentation. You can download them here: AMD Catalyst 14.6 Beta Linux
CPU Mining
For CPU mining I use minerd because it doesn't require any work to get running, simply download it and get to work. Download the built file for your machine 32-bit or 64-bit, and then unzip it and you're ready to go!
cd ~/Downloads tar -xvf pooler-cpuminer-2.3.2-linux-x86.tar.gz 
The executable is called minerd and it will be in ~/Downloads but you can move it to wherever you like. To run it, pull up terminal and do
cd ~/Downloads minerd --url=stratum+tcp://SERVER:PORT --userpass=USERNAME.WORKERNAME:WORKERPASSWORD 
You're done! Happy mining!
Common Issues
I ran into this and I've seen others with this problem as well. Everything installs fine but there is a shared library file that isn't where it should be. In fact, it isn't there at all.
 libudev.so.1: cannot open shared object file: No such file or directory 
In terminal, do
sudo updatedb locate libudev.so.0.13.0 
And it will probably return a path /lib/x86_64-linux-gnu. Inside that directory there's a library file called libudev.so.0.13.0. You'll need to make a symlink (aka shortcut) that links libudev.so.1 to libudev.so.0.13.0 So, assuming you're working with libudev.so.0.13.0 do this
cd /lib/x86_64-linux-gnu sudo ln -s libudev.so.0.13.0 libudev.so.1 
Now if you do
ln -l 
You should see
libudev.so.1 -> ./libudev.so.0.13.0 
Meaning you've made the symlink. Also, the text for libudev.so.1 will be blue.

Sono tornato e voglio sapere tutto quello che è successo in mia assenza!

Buongiorno eccomi qui. Per anni ho avuto la fissa della tecnologia. Appena mi alzavo la mattina la prima cosa che facevo era...la pipì. Ma poi correvo a leggere tutte le news che ruotavano intorno al mondo tecnologico e quindi: slashdot, techchrunch, punto-informatico ecc...
Poi nel 2011 ho perso completamente interesse, mi sembrava che il mondo con le app si fosse appiattito e che la tecnologia intorno al mondo IT fosse meno interessante, ma forse ero solo io che avevo bisogno di staccare la spina. Ora però voglio tornare, voglio di nuovo sapere tutto ciò che sta accadendo e che è accaduto negli anni passati.
Ho voglia però di essere aggiornato. Quali sono state secondo voi le tecnologie software/hardware, i servizi e le acquisizioni più importanti degli ultimi sei anni?
Aggiornerò questo post creando una timeline man mano che ognuno di voi fornirà informazioni attraverso i commenti.

OpenSSL Heartbleed vulnerability 11 April 2014What happened The version of OpenSSL used by Bitcoin Core software version 0.9.0 and earlier contains a bug that can reveal memory to a remote attacker. See http://heartbleed.com/ for details. What you should do Immediately upgrade to Bitcoin Core version 0.9.1 which is linked against OpenSSL version 1.0.1g. If you use the official binaries, you can verify the version of OpenSSL being used from the Bitcoin Core GUI's Debug window (accessed from the Help menu). If you compiled Bitcoin Core yourself or use the Ubuntu PPA, update your system's OpenSSL. Linux users should also upgrade their system's version of OpenSSL. Android Android version 4.1.1 is vulnerable to Heartbleed. Try if you can upgrade to at least Android 4.1.2. If you are using Bitcoin Wallet on an Android phone, you should upgrade the app to at least version 3.45. How serious is the risk If you are using the Windows version of the Bitcoin Core GUI without a wallet passphrase, it is possible that your wallet could be compromised by clicking on a bitcoin:. Payment request link If you are using bitcoind (on Linux, OSX, or Windows) , have enabled the-rpcssl option, and allow RPC connections from the Internet, an attacker from a whitelisted (-allowip) IP address can very likely discover the rpcpassword and the last rpc request. It is possible (but unlikely) private keys could be sent to the attacker.
