[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.

Has anyone been able to export private keys from Armory?

Hi everyone,
I am super pissed but I am going to try and keep it low key. I have a wallet that I saved in Armory years ago, and I want to move coins from it now. I had looked online a few months ago, and it said that I could export the private keys from Armory and sweep them into Electrum.
Well, today I tried it in both Armory 1.35 on Windows and the latest version on Linux. It doesn't work at all.
You can open a window after choosing to backup individual keys, and there are checkboxes there for all the different types of keys you could want, but checking and unchecking them DOES NOTHING.
All you can get is the Armory backup string for the wallet. That you already have, if you have restored the wallet from a paper backup.
Time to download all 120Gb of the blockchain I guess. Has anyone ever exported private keys from Armory? Am I doing something wrong?
Thanks.
Edit: PSA: Armory does not work at all on a fresh Ubuntu 17 install. It just fails silently and doesn't install. Neither does it work on MacOS El Capitan. On Debian 8, not all of the dependencies are installed properly during installation. I'm afraid to update my Windows copy now.
Edit: Bit the bullet and did it. Got it working on Ubuntu and found out that you have to start bitcoind in the background and play with some Armory settings to get it to run, then downloaded the whole thing from bitcoin-qt. Turns out I was right - Armory doesn't know the private keys until after it has downloaded the whole blockchain. And spent an hour chewing through transactions. AND you've restarted it twice. But I finally got them. Thanks everyone!

Hey everyone. MacOS Mooncoin Core wallet now available.

So I've put this on bitcointalk, telegram and discord -- Finished a working build of the Mooncoin Core wallet for Mac OSX... mostly because nobody else was stepping up to do it and I kept on seeing demand for it every week.
https://github.com/michilumin/mooncoincore-wallet/releases/tag/0.13.9-segwit-MacOSFix-Boostfix
It's based on fixes from Bitcoin's repo, and forked off of 0.13.9-segwit (since I don't have access to commit anything to the original mooncoin repo.)
The changes made are visible in my repo, rather minor syntactical changes to allow it to compile under Boost 1.66 on Mac OS X; I've tested it under El Capitan, so it'd be good to get some people to try it under Sierra and High Sierra.
It's labeled as pre-release just because who knows if I missed a bug, but I've done several transactions in both directions with it, as well as importing existing wallets and backing them up, all without a hitch -- it's connecting to peers and syncing with no troubles as well. (Make sure to create a mooncoin.conf with addnode statements from one of the mooncoin block explorers in it to find peers faster!!)

Ethereum Newbie - Problem with transferring from Shapeshift to Mist

Hello All!
I am new to ethereum but very interested in the concept of it so I wanted to transfer some of my Bitcoin to ETH and store it in a Mist wallet. I first tried to exchange through Shapeshift with a small test amount (.001 Bitcoin), but still making sure it was higher than the minimum. I attempted to send test amounts to both the ether mainbase and a created account in the wallet. Shapeshift said it successfully sent the Ether, but it never appeared in my wallets.
These are new wallets with 0 balances, so I don't know if that somehow affects the miner fee (I'm not sure where that fee is taken out of). My Mist Ethereum-Wallet also hasn't fully synced to the node (taking days), so I don't know if that's the problem either.
Any help would be much appreciated. I thought about using one of the web wallets (myetherwallet or ethereumwallet), but I figured I would be safe and just use the "official" wallet.
PS I have a macbook running OS X El Capitan, not sure how much that affects anything.

Trying to protect Bitcoin private keys; need advice

Gentlemen,
I'm conducting automated, online transactions with a few dozen anonymous parties. They don't know me and I don't know them. There are occasions when my web application, or I as an individual, may hold Bitcoin in a custodial capacity for said parties. It's important that I protect the private keys corresponding to a large number of Bitcoin addresses which my application creates on-the-fly as needed.
I have a software development background and have read as much as I can about protecting sensitive data but am fairly new to the latter so I'd like to present you with an overview of my private key protection strategy and then ask what you, as experts, perceive to be possible vulnerabilities in my plan.
Here's my layout and plan:
My main work computer is a MacBook Pro running El Capitan. It's typically plugged into a multi-monitor setup in my home although I'll occasionally take it on the road with me, making it somewhat vulnerable to theft. The OS's built-in FileVault disk encryption is turned on.
My web application runs on a grid of Windows 2008 servers that live at Amazon Web Services (AWS). This grid of servers, plus my laptop, constitute the entirety of my network.
One of the servers in the grid is running SQL Server and in that database is a table, and in that table is a field called 'privateKey' which contains the private key for a single Bitcoin address. The table will contain many rows since there are many addresses to deal with. The 'privateKey' field is a binary stream containing (1) an initialization vector (length=16 bytes) and (2) an encrypted representation of the private key. My program uses the initialization vector and a secret password (length=32 bytes) as inputs into a symmetric encryption algorithm (.NET/RijndaelManaged) to decrypt and use the private key.
The secret password isn't stored in a file on the server. It's stored on my laptop in a human-readable document called 'specialFolder\myPasswords.txt'' in hex format. When the server app is started, a secondary helper app prompts for the secret password which I then copy/paste into the helper app's console over a Remote Desktop connection. The helper app's console is then closed and the secret password is then only held in RAM on the server, within the process of my application.
There are also Bitcoin private keys held outside of my application in "wallets" managed manually, by me, using a third party program called Electrum. Electrum runs on my laptop and uses one file to represent each wallet. (A 'wallet' is just a collection of Bitcoin addresses and their respective private keys). I've configured Electrum to store the wallet files in 'specialFolder\myWalletFolder' on the laptop. Electrum encrypts the wallet files such that the private keys contained therein can't be used without a strong password which is entered by me as needed at runtime.
Electrum uses a mechanism wherein the public/private keypairs it generates are created in a predetermined fashion using what the documentation refers to as a 'seed.' The seed is a long series of human words. If one knows the seed, the keys can be regenerated and the wallet restored. I keep backups of the wallet seeds in a file called 'specialFolder\myElectrumSeeds.txt' on my laptop.
If you've read this far, you may have noticed that I'm keeping a lot of sensitive information in plain text within 'specialFolder' on the laptop. But this really isn't a folder at all. It's actually a volume created and maintained using a program called VeraCrypt. I only 'mount' this encrypted volume when I need to access its contents and then I immediately 'unmount' it. The laptop is never left alone when 'specialFolder' is mounted. Mounting the volume requires a password. That password is known only to me and isn't stored on the laptop.
VeraCrypt stores and accesses the 'specialFolder' volume through a single file. That file is named 'veracryptFile.' veracryptFile lives on my laptop on a Dropbox-synchronized folder. Whenever the VeraCrypt volume (and thus 'veracryptFile') is modified, the changes are immediately propegated to (1) DropBox-owned servers and (2) a server in the grid at AWS, and (3) another private server at AWS that's in a different geographical location.
In addition, a physical printout of the contents of 'specialFolder\myPasswords.txt' and 'specialFolder\myElectrumSeeds' is kept in a safe deposit box at a local bank, to which only I have the key.
The parties with whom I do business may occasionally login to my app and execute transactions which result in Bitcoin being sent to them. Password theft obviously weighs heavily on my mind.
The SQL Server discussed earlier contains a table of all of my users, and that table contains a field called 'password.' The 'password' field contains: (1) a random byte sequence (length=32 bytes) and (2) a hash of a concatenation of the user's password and the random byte sequence. My program uses the random byte sequence and the password the user supplies at login as inputs into a hashing algorithm (.NET/SHA256Managed). If the hashing algorithm's output matches the hash stored in the database, the user is considered authenticated.
A user must be authenticated prior to executing a transaction that would result in a Bitcoin disbursement. In addition, each user is required to have a BitMessage address. When the transaction is submitted online, my program creates a 10-digit random string and sends it to the user's BitMessage address. That string must be entered by the user in order to begin execution of his transaction.
This BitMessage confirmation protocol is also required if the user wants to: (1) change his password, or (2) specify a different BitMessage address in his profile.
Given the strategy outlined above, do you see any glaring vulnerabilities ? Here are the attack vectors I've considered thus far:
LAPTOP IS STOLEN: perp would have to defeat Apple's FileVault encryption (assuming laptop was powered off when stolen) plus the VeraCrypt encryption on 'SpecialFolder'. I could recover the lost files via DropBox or my AWS-hosted DropBox peers.
LAPTOP IS TARGETED BY ROGUE APPLE STORE TECH-SUPPORT EMPLOYEE WITH ADMIN ACCESS: perp would have to defeat VeraCrypt encryption on 'SpecialFolder'.
DROPBOX ACCOUNT IS HACKED: perp would have to defeat VeraCrypt encryption on 'SpecialFolder'.
AMAZON SERVER IS ATTACKED: perp would need physical access to machine and have a way to probe RAM to obtain 'secretPassword' since it's not stored on the hard drive.
USER PASSWORD(S) ARE STOLEN: perp would also need access to the user's BitMessage account in order to steal Bitcoin from the compromised user.
Are there other attack scenarios I've overlooked? For the sake of this forum post, I'd like to limit attack vectors to technical exploits, not those of the violent or gangster variety (extortion, blackmail, etc.).
Thank you for your thoughts.
Best,
Shaniqua
