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.

Mega FAQ (Or: Please come here for your questions first)

Qbundle Guide (Step by step setup & Bootstrap) https://burstwiki.org/wiki/QBundle
1( I want to mine or activate My account. Where do find the multiple coins?
You only need 1, an outgoing transaction or reward reassignment will set the public key. Get them from:
https://www.reddit.com/burstcoinmining/comments/7q8zve/initial_burstcoin_requests/
Or (Faucet list)
https://faucet.burstpay.net/ (if this is empty, come back later)

Or
https://forums.getburst.net/c/new-members-introductions/getting-started-initial-burstcoin-requests
2( I bought coins on Bittrex and want to move to my new wallet, but can't. Why?
Bittrex will only send to accounts with a public key (not a Burst requirement) so see number 1 and either set the name on the account (IF you will not mine) or set the reward recipient to the pool. Either action will enable the account and allow for transfers from Bittrex.
3( I sent coins from Poloniex/anywhere to Bittrex and they don’t show up after a considerable time. Why?
You need to set an unencrypted message on the transaction, informing Bittrex which account to send the funds to (this is in the directions on Bittrex). Did you do this? Contact Bittrex support with all the details and eventually you will get your funds.
4( How much can I make on Burst?
https://explore.burst.cryptoguru.org/tool/calculate
Gives you an average over time assuming a few things like: Average luck/100% uptime/no overlapping/fees on pool/good plot scan time (<20 seconds) if you do not have all of these, you may not see that number.
5( If I use SSD’s would I make more money?
No, it’s 95% capacity and 5% scan time that determine success. More plot area = better deadlines = better chance of forging a block, or better rates from a pool.
6( What is ‘solo’ and ‘pool’ (wasn’t his name Chewbacca?)
Solo is where you attempt to ‘forge’ (mine) a block by yourself; you get 100% of the block reward and fees. But you only receive funds if you forge, no burst for coming in second place.
Pools allow a group of miners to ‘pool’ together their resources and when a miner wins, they give the pool the winnings (this is done by the reward assignment you completed earlier), it is then divided according to different percentages and methods and burst is sent out according to pool rules (minimum pay-out, time, etc.)
7( I have been mining for 2 days and my wallet doesn’t show any Burst WHY?
Mining solo: it is win-or-lose, nothing in between, and wining is luck and plot size. Pool mining: because it costs 1 burst to send burst, the pools have either a time requirement (every X days) or a minimum amount (100 burst +) so you need to research your pool. Some pools allow for you to set the limit (cryptoGuru and similar) to be met before sending
8( How do I see what I have pending?
On CryptoGuru, based pools, it’s the ‘Pending (burst)’ column, other pools, look for the numbers next to your burst ID. One is Paid and the other pending.
9( I’m part of a pool and I forged a block, but I didn’t recieve the total value of the block, why?
A pool has 2 basic numbers that denote the pay-out method, in the format ‘XX-XX’ (i.e. 50-50) The first number is the % paid to the block forger (miner) and the second is the retained value, which is paid to historic ‘shares’ (or, past blocks that the pool didn’t win, but had a miner that was ‘close’ to winning with a good submitted deadline)
Examples of pools:
0-100 (good for <40TB)
20-80 (30-80TB)
50-50 (60-200TB)
80-20 (150-250)
100-0 (solo mine, 150+ TB)
Please note that there is an overlap as this is personal preference and just guidance; a higher historical share value means a smoother pay-out regime, which some people prefer. If fees are not factored in, or are the same on different pools, the pay-out value will be the same over a long enough period.
10( Is XXX model of hard drive good? Which one do you recommend?
CHEAP is best. If you have 2 new hard drives, both covered by warranty, get the one with the lowest cost per TB (expressed as $/TB , calculated by dividing the cost by the number of terabytes) because plot size is KING,
11( How many drives can I have on my machine?
For best performance, you can have up to 2 drives per thread (3 on a new fast AVX2 CPU). So that quad-core core-2-quad can have up to 8 drives, but a more modern i7 with 4 cores + hyper threading can squeeze 8 * 3 or 24 drives. (Performance while scanning will suffer)
12( Can I game while I mine?
Some people have done so, but you cannot have the ‘maximum’ number of drives and play games generally.
13( Can I mine Burst and GPU mine other coins?
Yes, if you CPU Mine Burst.
14( I’m GPU plotting Burst and GPU mining another coin, my plots are being corrupted, why?
My advice is dedicating a GPU to either mining or plotting, don’t try to do both.
15( What is a ‘plot’?
A plot is a file that contains Hashes, these hashes are used to mine burst. A plot is tied to an account, but they can be created (with the same account ID) on other machines and connected back to your miner(s).
16( Where can I trade/buy/sell Burst?
A list of exchanges is maintained on https://www.reddit.com/burstcoin/ (on the right, ‘Exchanges’ tab) the biggest at the moment are Bittrex and Poloniex, some offer direct Fiat-to-Burst purchase (https://indacoin.com for example)
17( Do I have to store my Burst off the exchange?
No, but it’s safer from hackers who target exchanges, if you cannot guarantee the safety or security of your home computer from Trojans etc, then it might be best to leave on an exchange (but enable 2FA security on your account PLEASE!)
18( What security measures can I take to keep my coin safe?
When you create an account, sign out and back in to your wallet (to make sure you have copied the pass phrase correctly) and keep multiple copies of the key (at least one physically printed or written down and in a safe place, better in 2 places) do not disclose the passphrase to anyone. Finally use either a local wallet or a trusted web wallet (please research before using any web wallet)
19( How can I help Burst?
Run a wallet, which will act as a node (or if you’re a programmer, contact the Dev team Bring attention to burst (without ‘shilling’ or trying to get people to buy) And help translate into your local language
Be a productive member of the community and contribute experience and knowledge if you can, or help others get into Burst.
20( Will I get coins on the fork(s) and where will they be?
There will be no new coin, and no new coins to be given/air dropped etc, the forks are upgrades to burst and there will not be a ‘classic’ or ‘new’ burst.
21( Will I need to move my Burst off of the exchange for the fork?
No, your transactions are on the block chain, which will be used on the fork, they will be visible after the move; nothing will need to be done on your side.
22( Where can I read about the progress of Burst and news in general on the community?
There is no finer place than https://www.burstcoin.ist/
23( What are the communities for Burst and the central website?

24( When will Burst partner up with a company?
Burst is a currency, the USD does not ‘partner up’ with a company, the DEV team will not partner up and give over to special interests.
25( Why is the DEV team anonymous?
They prefer anonymity, as it allows them to work without constant scrutiny and questions unless they wish to engage, plus the aim is for Burst to become a major contender, and this brings issues with security. They will work and produce results, they owe you nothing and if you cannot see the vision they provide then please do not ‘invest’ for short term gain.
26( When moon/Lambo/$100/make me rich?
My crystal ball is still broken, come back to the FAQ later for answer (seriously, this is a coin to hold, if you want to day-trade, good luck to you)
27( How can I better educate myself and learn about Dymaxion?
Read about the Dymaxion here: https://www.reddit.com/burstcoin/wiki/dymaxion
28( My reads are slow, why?
There are many reasons for this, if your computer has a decent spec it’s likely due to USB3 hub issues, or plugging into a USB2 hub, but other reasons can be multiple plots in the same folder, but it’s best to visit the mining subreddit. They can help more than an simple FAQ https://www.reddit.com/burstcoinmining/
29( I have a great idea for Burst (not proof of stake related)?
Awesome! Please discuss with the DEV team on discord https://discordapp.com/invite/RPhpjVv
(Please be aware that this is a public forum, you need to find who to ask/tell)
30( I have a great idea for Burst (Proof of stake related)?
No. if you want a POS, find a POS coin. On the tangle which is being implemented a POS/POW/POC coin can be created, but BURST will always be POC mined. You are welcome to implement a proof of stake coin on this!
31( Will the Dev team burn any coins?
Burst is not an ICO, so any coins will need to be bought to be burnt. You are welcome to donate, but the DEV team have no intention of burning any coins, or increasing the coin cap.
32( When will there be an IOS wallet?
IOS wallet is completed; we are waiting for it to go on the app store. Apple is the delaying factor.
33( Why do overlapping plots matter?
Plots are like collections of lottery tickets (and if only one ticket could win). Having 2 copies is not useful, and it means that you have less coverage of ‘all’ the possible numbers. It’s not good, avoid.
34( My local wallet used to run, I synchronised it before and now it says ‘stopped’. when I start it, it stops after a few seconds, what should I do?
I suggest that you change the database type to portable MariaDB (on Qbundle, at the top, ‘Database’ select, ‘change database’) and then re-import the database from scratch (see 35)
35( Synchronising the block chain is slow and I have the patience of a goldfish. What can I do?
On Qbundle , ‘Database’ select ‘Bootstrap chain’ and make sure the CryptoGuru repository is selected, then ‘start Import’ this will download and quickly stuff the local database (I suggest Portable MariaDB, see 34) (lol, loop)
36( What will the block reward be next month/will the block rewards run out in 6 months?
https://www.ecomine.earth/burstblockreward/ Rewards will carry on into 2026, but transaction fees will be a bigger % by then, and so profitable mining will continue.
37( How can I get started with Burst (wallet/mining/everything) and I need it in a video
https://www.youtube.com/watch?v=LJLhw37Lh_8 Watch and be enlightened.
38( Can I mine on multiple machines with the same account?
Yes, if you want to pool mine this can be done (but be prepared for small issues like reported size being incorrect. Just be sure to keep question 33 in mind.)
39( Why do some of my drives take forever to plot?
Most likely they are SMR drives, it’s best to plot onto another SSD and then move the finished plot/part of a plot across to the SMR drive as this is much quicker. SMR drives are fine on the read, just random writes that are terrible.
So plot an SMR drive quickly, plot to a non SMR or better still SSD drive, in as big a chunk as possible (fewer files better) and move. a version of Xplotter, called Splotter, can do this easily.
https://github.com/NoParamedic/SPlotter
40( I have a great idea; why not get listed on more exchanges!!
Exchanges list coins because of 2 reasons:
  1. Clients email and REQUESTING Burst and provide details like:
    i. https://www.burst-coin.org/information-for-exchanges
  2. The coin pays (often A LOT, seriously we’ve been asked for 50 BTC)
I suggest you speak with your exchange and ask ‘when will they offer Burst?’
41( Do you have a roadmap?
https://www.burst-coin.org/roadmap
42( Why is the price of Burst going up/down/sideways/looping through time?
The price of burst is still quite dependent upon Bitcoin, meaning that if Bitcoin gains, the value of Burst gains, if Bitcoin drops then Burst also drops. If there is news for Burst then we will see something independent of Bitcoin moving. Variations can be because of people buying in bulk or selling in bulk. There are also ‘pump and dump’ schemes that we detest, that can cause spikes in price that have nothing to do with news or Bitcoin, just sad people taking advantage of others.
43( Where is the best place to go with my mining questions?
https://www.reddit.com/burstcoinmining/
or https://t.me/BurstCoinMining
44( What hardware do you advise me to buy, is this computer good?
See question 43 for specific questions on hardware, it depends on so many variables. The ‘best’ in my opinion is a 36 bay Supermicro storage server, usually they have dual 6-core CPU’s and space for 36 drives. No USB cables, plotting and mining monster, anything else, DYOR.
45( Where do you buy your hard drives?
I have bought most from EBay in job lots, and some refurbished drives with short warranties. Everything else I have bought, from Amazon.
46( Can I mine on my Google drive/cloud based storage?
In short: no. If you want to try, and get to maybe 1 TB and then find that your local connection isn’t fast enough, or that shortly after, your account is blocked for various reasons. Please be my guest.
47( Can I mine on my NAS?
Some you can mine with the NAS (if it can run the miner, it can scan locally) but generally they’re not very fast. good for maybe 16 TB? Having a plot on a NAS and mining from another computer depends on the network speed between the NAS and scanning computer. I believe you can scan about 8 TB (maybe a bit more) and keep the scan times to within acceptable, but YMMV.
48( How can I set up a node?
No need to set up a node, just set up a wallet (version 2.0.4) or Qbundle (2.2) and it will do the rest
49( Are the passphrases secured?
I’ll leave the effort to a few people to show how secure a 12-word passphrase is: https://burstforum.net/topic/4766/the-canary-burst-early-warning-system Key point: brute forcing it will be around 13,537,856,339,904,134,474,012,675,034 years.
50( I logged into my account (maybe with a different burst ID) and see no balance!!
I have dealt with this very issue multiple times, and there are only 3 options:
  1. You have typed in the password incorrectly
  2. You have copy-pasted the password incorrectly
  3. You are trying to log into a ‘local wallet’ which the block chain has not finished updating
The last one generally leaves the burst ID the same, but old balances will show. No, this is not a security problem, and yes, windows loves to add spaces after the phrase you enter when copied, and that space is important in getting to your account.
51( Are there channels for my language?
Telegram:
Spanish: https://t.me/burstcoin_es
German: https://t.me/Burstcoinde
Italian: https://t.me/BurstCoinItalia
Forum:
Spanish: https://burst-coin.es/index.php/forum/index
Discord:
Spanish: https://discordapp.com/invite/RaaGna9
Bulgarian: https://discord.gg/r4uzTd
(there are others, please contact me to put up)
52( I am mining in a pool, and it says that my effective capacity is lower than I actually have, why?
  1. If you've not been mining for >48 hours, or just added additional capacity, it will take time.
  2. The value fluctuates (normally, +-5% but can be up to 10% at times)
  3. Read on the ‘Quick info’ tab about adjusting your deadline to compensate for changes i. revisit once a month for best results
  4. If you have overlapping plots it will also be lower so be aware of this (see question 33)
53( What pool should I join?
First of all, read question 9, after you have understood that it depends on the size (and how patient you are) select from the following list: https://www.ecomine.earth/burstpools/
54( What miner to use?
I use Blago’s miner, there are many out there but Blago’s works for me on CPU mining, it can be found in Qbundle.
55( What Wallet to use (I use windows)?
Qbundle: https://github.com/PoC-Consortium/Qbundle/releases/ guide: https://burstwiki.org/wiki/QBundle
56( What Wallet to use (Linux)?
https://package.cryptoguru.org/ for Debian and Ubuntu, for Mac. read:
https://www.ecomine.earth/macoswalletinstallguide/
57( Will i need to 'replot' after POC2 (second fork) happens?
No, there will be a tool which will optimise, but it is not CPU intensive (it basically re-shuffles your plot) and is just IO intensive. You do not need to replot.
TurboPlotter and https://github.com/PoC-Consortium/Utilities/tree/mastepoc1to2.pl are tools that will/can be used to actuate optimization, but PLEASE wait with optimization until after the hard fork.
58( Will the transaction fee always be 1 burst?
No, dynamic fees are coming in the next fork.

uTorrent download limit not working correctly

Hello,
I use an old version of utorrent for various reasons, version 2.2.1 (25110). I noticed something different when enabling the Bandwidth > 'Global Download Rate Limiting' > 'Maximum download rate (kB/s)'. If I set it to zero (unlimited) my DL rate will go to 10 MB/s, which is full speed on my 100 mbps internet.
If I set it to anything other then 0, like say 7168, my speeds will crash. Like down to 100-300 KB/s. As soon as I put 0 in there and hit apply, it instantly goes back up to 10 MB/s.
I am using debian linux disc 1 to test, which is always fast with lots of seeds and peers.
How does the rate limit work? And why is it killing my DL speeds so much. I am not changing anything else, and leave my upload limit set to 768.
The reason I want to stick with utorrent, is that I wrote a (very) custom powershell script that uses the web ui to remove torrents once they are done, along with tons of other automation. I don't want to lose the functionality that I wrote via the web API from switching to another app.
I know 2.2.1 is old as hell, but I don't know of a newer version that doesn't suck, between ads, bitcoin miners, etc.

Zeus/Gaw ASIC Setup Guide for Linux/Raspberry Pi

So I recently I became quite interested in mining and cyptocurrencies in general. So interested in fact that I bit the bullet and decided to buy myself a GAW Fury.
I then spent some time doing research on how to set up a GAW or Zeus ASIC on Linux, in particular on a Raspberry Pi, and have found most guides to be awful. The reason they are so bad IMHO is that they assume quite a bit of prior knowledge, either with Linux or mining, and give very little instructions. So I have tried to put together a guide that requires very little prior knowledge.
It is my aim that anyone could get their shiny new asic up and mining in no time using this guide. Anyway, I present...

The Complete Noobs Guide to Setting Up a Zeus or Gaw ASIC on Debian/Ubuntu/Raspberry Pi

Resources

About Cyrptocurrencies and Their Jargon

If you are new to cryptocurrencies and how they work I suggest taking a look at this series of KhanAcademy videos. They are for Bitcoin but the theory is the same. I found them very helpful when it came to understanding what mining actually does and the mechanics of cyrptocurrencies.
Also take a look at sircamm22 his info found here, is great and breaks down a large number of concepts. I slightly disagree with no. 21 regarding preordering. Just exercise common sense.

Linux

If you are new to Linux you could follow along by simply typing in the commands. However I highly recommend taking the time to learn what you are doing. This course is a great place to start.

Computer Setup

By the end of this section you will have your device turned on, fully setup and connected to the internet with.
Note: Commands to be typed into the command line will be displayed like this:
echo Hello World

Desktop/Laptop

For laptops and desktops already running Ubuntu or Debian I will assume you have setup your internet setup as part of the installation.
If not: There are plenty of guides out there and the installation/setup process is very easy. A good place to start for Ubuntu is here.
Now open up a terminal window. Ctrl + alt + t on a standard Ubuntu installation.
If you plan on using this PC without a monitor I would suggest installing an SSH Server.
These commands will be discussed later on in the guide.
sudo apt-get -y install openssh-server
sudo service openssh-server start

Raspberry Pi

The Raspberry Pi Foundation has put together a great guide in PDF format.
Use NOOBS it will save you a lot of trouble. NB: Some SD cards don't support NOOBs but will work fine if the image is put on using a different method.
Here is a great guide for setting up the Raspberry Pi SD card from Elinux.org. In fact it's a great place to start for anything RPi related. Raspberry Pi hub at Elinux.
Once the SD card is setup you will need to insert it into the Raspberry Pi and boot. Install Raspbian from the NOOBs menu and wait.
Follow this guide by Adafruit for first time setup. You will need to enable SSH Server.
I suggest not starting the desktop on boot. It can be easily run from the command line by typing startx.
Follow this guide by Adafruit to setup your network. Found here. No need to do this if you set up previously in the first time config.
We will also at this point want to setup ssh. Again I will point you to an Adafruit guide.
Once done exit back to a standard command line interface. This can be done in LXDE by using the power off menu located in the bottom right corner.

Miner Setup

Installing BFGMiner

If you want to the Raspberry Pi or PC without a monitor go ahead and SSH into your device.
So now you should be staring at a command line interface whether on the device with a monitor or via SSH.
First things first lets make sure we are all up to date. This will update our package list from the repositories and upgrade them to the newest version. "-y" Will simply say yes to any prompts.
sudo apt-get update && sudo apt-get -y upgrade
We are going to need to install some useful tools. Git-core is how we will clone and download BFGMiner from GitHub and Screen allows multiple command line instances and means if we exit out of ssh session or quit Terminal on Ubuntu, BFGMiner will continue to run.
sudo apt-get install git-core screen
We also need to download some other tools/dependencies to ensure that BFGMiner will compile successfully.
sudo apt-get -y install build-essential autoconf automake libtool pkg-config libcurl4-gnutls-dev libjansson-dev uthash-dev libncursesw5-dev libudev-dev libusb-1.0-0-dev libevent-dev libmicrohttpd-dev libc-bin
Ok now change into your home directory.
cd ~
And clone BFGMiner by Darkwinde.
git clone https://github.com/Darkwinde/bfgminer.git
Once the download has completed move into the bfgminer directory.
cd bfgminer
The following steps may take a while.
Now run autogen.sh
sudo ./autogen.sh
You will need to make the configure script execuitable.
sudo chmod +x ./configure
Now configure bfgminer
sudo ./configure CFLAGS="-O3" --enable-scrypt
Now lets make!
sudo make
Install BFGMiner
sudo make install
One more thing...
sudo ldconfig

Running BFGMiner

If you haven't already plug in your ASIC.
Just confirm your system is recognising the ASIC.
lsusb
Its output should look similar to this (no need to type this in):
Bus 001 Device 005: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Yep there it is our ASIC listed as device 005. There is no need to install any drivers, unlike in windows, as they come in the kernel.
Now lets actually start BFGMiner.
You will want to start a screen session to ensure BFGMiner doesn't quite when you exit.
"-S" is the option for starting a new screen session. You can replace "miner" with anything you like.
screen -S miner
Now you can run the commands below.
Here is a sample of what you should type. You will need to replace somethings with your own values.
sudo bfgminer --scrypt -o stratum+tcp://URL:PORT -u USERNAME -p PASSWORD --zeus-cc CHIPCOUNT --zeus-clk 328 -S zeus:/dev/ttyUSB0
Where:
URL:PORT is the address and port of the pool you wih to use. Now I won't suggest a pool. I will leave that decision up to you. If you do wish to mine DOGE take a look at this site for a list of pools and comparisons.
USERNAME this is the username you use on the pool. Every pool is different. Check your pool's website for details. PASSWORD same as above. Specific to your pool, not every pool requires one.
CHIPCOUNT this is specific to which ASIC you are using.
For GAWMiner ASIC's:
  • War Machine: 256
  • Falcon: 128
  • Black Widow: 64
  • Fury: 6
For ZeusMiner ASIC's:
  • Blizzard: 6
  • Cyclone: 96
  • Hurricane X2: 48
  • Hurricane X3: 64
  • Thunder X2: 96
  • Thunder X3: 128
Now to make sure you don't stop mining when you exit ssh or terminal. Press:
ctrl + a + d
To come back to the BFGMiner screen simply run:
screen -r miner
You're done!!

Start on Boot

First off you will want to make sure you have BFGMiner running correctly. Ensure you have the miners set up properly and your pool correctly configured.
Start a BFGMiner instance, detailed above.
Once the instance has started and you are happy with how everything is working press "s" on your keyboard to enter the settings menu.
Now press the "w" key. Don't press enter. We want to specify where our config will go. Type:
/home/USERNAME/bfgminer.conf
Substitute USERNAME for your user. On a standard RPI install its pi. On ubuntu it's what you set during the instillation.
Now press the enter key to return back to the main BFGMiner screen. Press "q" on your keyboard to exit BFGMiner. You should now be back in the command line.
Now we want to edit a file called rc.local. Any commands in this file will be executed on boot.
sudo nano /etc/rc.local
Depending on your system this file may already contain some commands. Be careful not to delete them.
After the last command and before "exit 0" type the following on one line:
sudo -u USERNAME screen -d -m sudo bfgminer --config /home/USERNAME/bfgminer.conf
Where USERNAME = your username
Hit ctrl + x then y to save and exit nano.
The above command will create a new screen session and run bfgminer using the config we created earlier. All while as our username so that we can easily reattach.
Lets reboot to ensure it is working correctly:
sudo reboot
Once rebooted and logged in, show all running screen sessions:
screen -ls
Reattach to the session. You only need to use the numbers before the first dot.
e.g Mine looks like: 2480..hostname (13/07/14 12:02:09) (Detached). So I type:
screen -r 2480
Verify everything worked as expected. Then ctrl + a + d to exit.
You have now setup BFGMiner to restart on reboot.

Power Failure

If you are using a Raspberry Pi and it loses power it will automatically reboot on receiving power again.
For standard desktop PCs there is an option in some BIOS/UEFI to turn the computer on when it receives power. Consult your motherboard's manual and manufacturer's website.

Sources

Here is where I got my info from.
And of course /dogemining

Wrap Up

Congrats you've done it. You have managed to successfully get your shiny new asic mining away.
I do plan to make another guide detailing how to setup and use StarMiner a ready to go RPi mining distro.
So I hope this is helpful for you guys. I have seen lots of posts asking the exact same questions again and again and I have tried to answer these as best I can. I am still learning about this stuff so if there is something I have missed or a mistake I have made please tell me.
Anyway good luck. And I'll see you at the moon.
Cheers Frogsiedoodle
Edit 1: Layout and formatting.
Edit 2: Added instructions for screen which I initially forgot.
Edit 3: Removed 1 unneeded dependency
Edit 4: Added section on start on reboot and power failure.

To the moon! Dogemining with BFGMiner, Debian, and ATI.

Visitor from the future! Hello. I'm a newbie digger and recently setup my first dedicated mining box in Debian. I'm not the most experienced Linux user, but the machine had started with Debian Squeeze and I couldn't find its old Windows key. (Also please forgive formatting errors, I'm new to this whole "Reddit" thing as well.)
I found a number of guides to misdirect me on my way, so I decided to write up a sort-of (or at least hopefully up-to-date) guide to create a Dogecoin miner on Debian with AMD cards, using BFGMiner to mine coins.
Expert digging shibes: I would certainly appreciate feedback to improve this guide.
This is not a headless mining guide. I have not reached that level of mastery yet, though I believe it is well within reach.
HOWTO
You can refer to this wiki source to understand the output from BFGMiner 3.10.0. The one gotcha I've observed is that BFGMiner will happily start off showing hash rates in KHash/sec, and after the first accepted block it will jump to MHashes/sec. When I first saw my hash speed appear to drop from "250" to "0.2", I panicked a little before seeing it had changed its orders of magnitude.
If you think you're still mining slowly, you might need to bump up the intensity for BFGMiner. Higher intensity means more work, and it's possible to create hardware failures if you set it too high. For my HD 5870s, I use an intensity of 12. You can either set the intensity by adding "-I 12" to the ./bfgminer line of doge_dig.sh, or you can adjust the value by pressing M in BFGMiner and working through the menu system from there.
Bonus: Multiple cards
What happens if I have multiple ATI cards on one rig, you ask? I had the same problem, and OpenCL would only recognize one of them! It turns out that there's an easy solution, but it costs $1.25 in resistors from your local radio shack: http://www.overclock.net/t/384733/the-30-second-dummy-plug
Plug the finished product from there into your second card. If you have more than two cards, you'll need to make one for every card you want to recognize without a monitor attached to it. Reboot and restart your mining, BFGMiner should recognize all of your cards now.
In theory, the above technique should allow you to run completely headless, as long as you also install SSH and be sure to have your script export DISPLAY=:0 before running BFGMiner. I haven't tried this, though.
Happy mining and welcome to the Moon! I hope this is helpful to someone.

Upgrading and downgrading

How to Upgrade
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 (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
bitcoind/bitcoin-qt (on Linux).
Downgrading warning
Because release 0.10.0 makes use of headers-first synchronization and parallel
block download (see further), the block files and databases are not
backwards-compatible with older versions of Bitcoin Core or other software:
  • Blocks will be stored on disk out of order (in the order they are
received, really), which makes it incompatible with some tools or
other programs. Reindexing using earlier versions will also not work
anymore as a result of this.
  • The block index database will now hold headers for which no block is
stored on disk, which earlier versions won't support.
If you want to be able to downgrade smoothly, make a backup of your entire data
directory. Without this your node will need start syncing (or importing from
bootstrap.dat) anew afterwards. It is possible that the data from a completely
synchronised 0.10 node may be usable in older versions as-is, but this is not
supported and may break as soon as the older version attempts to reindex.
This does not affect wallet forward or backward compatibility.
Notable changes

Faster synchronization
Bitcoin Core now uses 'headers-first synchronization'. This means that we first
ask peers for block headers (a total of 27 megabytes, as of December 2014) and
validate those. In a second stage, when the headers have been discovered, we
download the blocks. However, as we already know about the whole chain in
advance, the blocks can be downloaded in parallel from all available peers.
In practice, this means a much faster and more robust synchronization. On
recent hardware with a decent network link, it can be as little as 3 hours
for an initial full synchronization. You may notice a slower progress in the
very first few minutes, when headers are still being fetched and verified, but
it should gain speed afterwards.
A few RPCs were added/updated as a result of this:
  • getblockchaininfo now returns the number of validated headers in addition to
the number of validated blocks.
  • getpeerinfo lists both the number of blocks and headers we know we have in
common with each peer. While synchronizing, the heights of the blocks that we
have requested from peers (but haven't received yet) are also listed as
'inflight'.
  • A new RPC getchaintips lists all known branches of the block chain,
including those we only have headers for.
Transaction fee changes
This release automatically estimates how high a transaction fee (or how
high a priority) transactions require to be confirmed quickly. The default
settings will create transactions that confirm quickly; see the new
'txconfirmtarget' setting to control the tradeoff between fees and
confirmation times. Fees are added by default unless the 'sendfreetransactions'
setting is enabled.
Prior releases used hard-coded fees (and priorities), and would
sometimes create transactions that took a very long time to confirm.
Statistics used to estimate fees and priorities are saved in the
data directory in the fee_estimates.dat file just before
program shutdown, and are read in at startup.
New command line options for transaction fee changes:
  • -txconfirmtarget=n : create transactions that have enough fees (or priority)
so they are likely to begin confirmation within n blocks (default: 1). This setting
is over-ridden by the -paytxfee option.
  • -sendfreetransactions : Send transactions as zero-fee transactions if possible
(default: 0)
New RPC commands for fee estimation:
  • estimatefee nblocks : Returns approximate fee-per-1,000-bytes needed for
a transaction to begin confirmation within nblocks. Returns -1 if not enough
transactions have been observed to compute a good estimate.
  • estimatepriority nblocks : Returns approximate priority needed for
a zero-fee transaction to begin confirmation within nblocks. Returns -1 if not
enough free transactions have been observed to compute a good
estimate.
RPC access control changes
Subnet matching for the purpose of access control is now done
by matching the binary network address, instead of with string wildcard matching.
For the user this means that -rpcallowip takes a subnet specification, which can be
  • a single IP address (e.g. 1.2.3.4 or fe80::0012:3456:789a:bcde)
  • a network/CIDR (e.g. 1.2.3.0/24 or fe80::0000/64)
  • a network/netmask (e.g. 1.2.3.4/255.255.255.0 or fe80::0012:3456:789a:bcde/ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff)
An arbitrary number of -rpcallow arguments can be given. An incoming connection will be accepted if its origin address
matches one of them.
For example:
| 0.9.x and before | 0.10.x |
|--------------------------------------------|---------------------------------------|
| -rpcallowip=192.168.1.1 | -rpcallowip=192.168.1.1 (unchanged) |
| -rpcallowip=192.168.1.* | -rpcallowip=192.168.1.0/24 |
| -rpcallowip=192.168.* | -rpcallowip=192.168.0.0/16 |
| -rpcallowip=* (dangerous!) | -rpcallowip=::/0 (still dangerous!) |
Using wildcards will result in the rule being rejected with the following error in debug.log:
 Error: Invalid -rpcallowip subnet specification: *. Valid are a single IP (e.g. 1.2.3.4), a network/netmask (e.g. 1.2.3.4/255.255.255.0) or a network/CIDR (e.g. 1.2.3.4/24). 
REST interface
A new HTTP API is exposed when running with the -rest flag, which allows
unauthenticated access to public node data.
It is served on the same port as RPC, but does not need a password, and uses
plain HTTP instead of JSON-RPC.
Assuming a local RPC server running on port 8332, it is possible to request:
In every case, EXT can be bin (for raw binary data), hex (for hex-encoded
binary) or json.
For more details, see the doc/REST-interface.md document in the repository.
RPC Server "Warm-Up" Mode
The RPC server is started earlier now, before most of the expensive
intialisations like loading the block index. It is available now almost
immediately after starting the process. However, until all initialisations
are done, it always returns an immediate error with code -28 to all calls.
This new behaviour can be useful for clients to know that a server is already
started and will be available soon (for instance, so that they do not
have to start it themselves).
Improved signing security
For 0.10 the security of signing against unusual attacks has been
improved by making the signatures constant time and deterministic.
This change is a result of switching signing to use libsecp256k1
instead of OpenSSL. Libsecp256k1 is a cryptographic library
optimized for the curve Bitcoin uses which was created by Bitcoin
Core developer Pieter Wuille.
There exist attacks[1] against most ECC implementations where an
attacker on shared virtual machine hardware could extract a private
key if they could cause a target to sign using the same key hundreds
of times. While using shared hosts and reusing keys are inadvisable
for other reasons, it's a better practice to avoid the exposure.
OpenSSL has code in their source repository for derandomization
and reduction in timing leaks that we've eagerly wanted to use for a
long time, but this functionality has still not made its
way into a released version of OpenSSL. Libsecp256k1 achieves
significantly stronger protection: As far as we're aware this is
the only deployed implementation of constant time signing for
the curve Bitcoin uses and we have reason to believe that
libsecp256k1 is better tested and more thoroughly reviewed
than the implementation in OpenSSL.

Watch-only wallet support
The wallet can now track transactions to and from wallets for which you know
all addresses (or scripts), even without the private keys.
This can be used to track payments without needing the private keys online on a
possibly vulnerable system. In addition, it can help for (manual) construction
of multisig transactions where you are only one of the signers.
One new RPC, importaddress, is added which functions similarly to
importprivkey, but instead takes an address or script (in hexadecimal) as
argument. After using it, outputs credited to this address or script are
considered to be received, and transactions consuming these outputs will be
considered to be sent.
The following RPCs have optional support for watch-only:
getbalance, listreceivedbyaddress, listreceivedbyaccount,
listtransactions, listaccounts, listsinceblock, gettransaction. See the
RPC documentation for those methods for more information.
Compared to using getrawtransaction, this mechanism does not require
-txindex, scales better, integrates better with the wallet, and is compatible
with future block chain pruning functionality. It does mean that all relevant
addresses need to added to the wallet before the payment, though.
Consensus library
Starting from 0.10.0, the Bitcoin Core distribution includes a consensus library.
The purpose of this library is to make the verification functionality that is
critical to Bitcoin's consensus available to other applications, e.g. to language
bindings such as [python-bitcoinlib](https://pypi.python.org/pypi/python-bitcoinlib) or
alternative node implementations.
This library is called libbitcoinconsensus.so (or, .dll for Windows).
Its interface is defined in the C header [bitcoinconsensus.h](https://github.com/bitcoin/bitcoin/blob/0.10/src/script/bitcoinconsensus.h).
In its initial version the API includes two functions:
  • bitcoinconsensus_verify_script verifies a script. It returns whether the indicated input of the provided serialized transaction
correctly spends the passed scriptPubKey under additional constraints indicated by flags
  • bitcoinconsensus_version returns the API version, currently at an experimental 0
The functionality is planned to be extended to e.g. UTXO management in upcoming releases, but the interface
for existing methods should remain stable.
Standard script rules relaxed for P2SH addresses
The IsStandard() rules have been almost completely removed for P2SH
redemption scripts, allowing applications to make use of any valid
script type, such as "n-of-m OR y", hash-locked oracle addresses, etc.
While the Bitcoin protocol has always supported these types of script,
actually using them on mainnet has been previously inconvenient as
standard Bitcoin Core nodes wouldn't relay them to miners, nor would
most miners include them in blocks they mined.
bitcoin-tx
It has been observed that many of the RPC functions offered by bitcoind are
"pure functions", and operate independently of the bitcoind wallet. This
included many of the RPC "raw transaction" API functions, such as
createrawtransaction.
bitcoin-tx is a newly introduced command line utility designed to enable easy
manipulation of bitcoin transactions. A summary of its operation may be
obtained via "bitcoin-tx --help" Transactions may be created or signed in a
manner similar to the RPC raw tx API. Transactions may be updated, deleting
inputs or outputs, or appending new inputs and outputs. Custom scripts may be
easily composed using a simple text notation, borrowed from the bitcoin test
suite.
This tool may be used for experimenting with new transaction types, signing
multi-party transactions, and many other uses. Long term, the goal is to
deprecate and remove "pure function" RPC API calls, as those do not require a
server round-trip to execute.
Other utilities "bitcoin-key" and "bitcoin-script" have been proposed, making
key and script operations easily accessible via command line.
Mining and relay policy enhancements
Bitcoin Core's block templates are now for version 3 blocks only, and any mining
software relying on its getblocktemplate must be updated in parallel to use
libblkmaker either version 0.4.2 or any version from 0.5.1 onward.
If you are solo mining, this will affect you the moment you upgrade Bitcoin
Core, which must be done prior to BIP66 achieving its 951/1001 status.
If you are mining with the stratum mining protocol: this does not affect you.
If you are mining with the getblocktemplate protocol to a pool: this will affect
you at the pool operator's discretion, which must be no later than BIP66
achieving its 951/1001 status.
The prioritisetransaction RPC method has been added to enable miners to
manipulate the priority of transactions on an individual basis.
Bitcoin Core now supports BIP 22 long polling, so mining software can be
notified immediately of new templates rather than having to poll periodically.
Support for BIP 23 block proposals is now available in Bitcoin Core's
getblocktemplate method. This enables miners to check the basic validity of
their next block before expending work on it, reducing risks of accidental
hardforks or mining invalid blocks.
Two new options to control mining policy:
  • -datacarrier=0/1 : Relay and mine "data carrier" (OP_RETURN) transactions
if this is 1.
  • -datacarriersize=n : Maximum size, in bytes, we consider acceptable for
"data carrier" outputs.
The relay policy has changed to more properly implement the desired behavior of not
relaying free (or very low fee) transactions unless they have a priority above the
AllowFreeThreshold(), in which case they are relayed subject to the rate limiter.
BIP 66: strict DER encoding for signatures
Bitcoin Core 0.10 implements BIP 66, which introduces block version 3, and a new
consensus rule, which prohibits non-DER signatures. Such transactions have been
non-standard since Bitcoin v0.8.0 (released in February 2013), but were
technically still permitted inside blocks.
This change breaks the dependency on OpenSSL's signature parsing, and is
required if implementations would want to remove all of OpenSSL from the
consensus code.
The same miner-voting mechanism as in BIP 34 is used: when 751 out of a
sequence of 1001 blocks have version number 3 or higher, the new consensus
rule becomes active for those blocks. When 951 out of a sequence of 1001
blocks have version number 3 or higher, it becomes mandatory for all blocks.
Backward compatibility with current mining software is NOT provided, thus miners
should read the first paragraph of "Mining and relay policy enhancements" above.

Recommendations and help with miner install on a debian server

I've been playing with bitcoin for a while and have set the normal bitcoind up as a daemon and have been running that in mining mode, but haven't generated any actual coins.
Going with the idea, I've got some little-used servers and I want to install bitcoin miners on them and have them join a pool. To me, MtRed seems fine.
These are rack-mounted machines that I access with ssh. Hell, I don't even know if they have a graphics card in them, but I figure with their CPUs I can do a little work.
My attempt is with phoenix, just because I read that it could do both CPUs and GPUs. I'm pretty sure I have all the dependencies fulfilled, did the build and install with no errors, but it segfaults when I try to run it.
phoenix's docs, or rather the lack of them, reminds me of the bad old days of Linux. Maybe too many slick debian package installs has softened me. :-)
