How to get a public static ip for your local lightning node

My lightning node is a node that is running locally on my server hardware in my house down under, far from the New Jersey Digitalocean datacenter, which is what will come up if you look up the ip of the node. This is done via an OpenVPN tunnel from your local machine to a VPS. I am doing this by renting a VPS from Digitalocean for $20 a month (2 vCPUs, 2GB RAM) running Ubuntu 18.04. You can do this just as easily on a $5 a month VPS with 1 vCPU and 1GB RAM or even a $2.50 a month VPS from Vultr with 512MB RAM. I needed the extra power because I have many web services running there as well.
This setup allows me to have a highly available lightning node, not affected by my home IP address changing. If you are using a mobile connection or have a CGNAT, you wont be able to port forward for your lightning node. This setup allows you to do so. You can also use this to make a portable lightning node, which can get you a full lightning node wherever you have power and internet, without having to mess with network settings. If you don't want others to know your home IP, this is a good option for privacy.
  1. Setup a local lightning node, preferably on a linux machine. I followed the Raspibolt tu`ial (with some tweaks) on a 2 vCPU and 8GB RAM VM running Ubuntu 16.04.
  2. Get a VPS with a static IP address. Digitalocean and Vultr VPSs already are. This VPS wont need much power, so get the cheapest one you can.
  3. Secure the VPS. I used this tutorial. Essentially, setup a non root user, use ssh keys, and setup ufw. Also make sure to allow port 9735 through ufw for lightning. I also additionally made adjustments to the ssh config and installed fail2ban.
  4. Setup an OpenVPN server on the VPS. I used this tutorial.
  5. Install on OpenVPN client on the local linux machine and connect to the server. The tutorial from step 4 shows how to this. Keep this connected for step 6.
  6. SSH into the VPS and figure out the OpenVPN IP address of the client. It should be 10.8.0.x. To figure out the x, setup a simple python web server or something on the local machine on port 8000 or something and open the port on ufw in the local machine. Keep the OpenVPN connection, and use a new ssh session when accessing your local machine. Don't kill the OpenVPN connection, as it may complicate things when finding the ip.
    mkdir testweb
    cd testweb
    echo hello >> index.html
    sudo ufw allow 8000
    python -m SimpleHTTPServer 8000
  7. SSH back into the VPS. Run the curl command below, and try all the numbers between 2-10 for x. When you get hello as your output, then you found the right IP. I found mine at 6. You may have to try higher numbers, but this is unlikely. You can kill your python webserver on your local machine once you find it.
    curl 10.8.0.x:8000
  8. Once you have the IP, you want to make this static, so it doesn't change when you reconnect. This is done on the VPS side, so ssh back into the VPS. This tutorial worked for me. Just make sure to change values like the CommonName and and the IP to match yours (client1 and 10.8.0.x). If it doesn't work search "make openvpn ip static" and look around.
  9. SSH into your local machine, and make the OpenVPN connection persistent. You can kill the OpenVPN connection now. Doing this and this worked for me. If it doesn't work search "openvpn keepalive" or "openvpn auto connect linux" or "make openvpn connection persistent linux".
  10. Restart your local machine, and make sure it connects on boot. Do the python webserver test again, and make sure the same ip is shown on the VPS, and it is still accessible.
  11. SSH back into the VPS. Now, you have to port forward with iptables. you have to add the 2 lines below starting with -A PREROUTING in the same place in your /etc/ufw/before.rules file. Here is what mine looks like. Change the x to your OpenVPN IP. Do sudo ufw disable and sudo ufw enable to restart ufw to update your changes.
    *nat
    :POSTROUTING ACCEPT [0:0]
    -A PREROUTING -i eth0 -p tcp -m tcp --dport 9735 -j DNAT --to-destination 10.8.0.x:9735
    -A PREROUTING -i eth0 -p udp -m udp --dport 9735 -j DNAT --to-destination 10.8.0.x:9735
    -A POSTROUTING -s 10.8.0.0/8 -o eth0 -j MASQUERADE
    COMMIT
  12. SSH into your local machine. Change your lnd.conf to match with this setup, like changing the externalip. Here is what my config looks like, a slight tweak from the Raspibolt one:
    [Application Options]
    debuglevel=info
    maxpendingchannels=5
    alias=GCUBED [LND]
    color=#68F442
    listen=0.0.0.0:9735
    externalip=157.230.95.74:9735
    [Bitcoin]
    bitcoin.active=1
    bitcoin.mainnet=1
    bitcoin.node=bitcoind
    [autopilot]
    autopilot.active=1
    autopilot.maxchannels=5
    autopilot.allocation=0.6
  13. Do a sudo service lnd restart to restart lnd and apply the changes. Remember to do a lncli unlock after any restarts. Your lnd node should now have a public static ip. Look it up a few hours after you do this on 1ml, your ip should be the one of your VPS now.
I am monitoring this for free with uptimerobot. It will notify you if it has gone down. So far mine has been running for 3 days and hasn't gone down.
EDIT: Formatting
EDIT 2: The main reason I didn't use a ddns or a hidden service was mainly for high uptime, and low latency. I am planning on developing a lapp with this node and I didn't want to risk any downtime. Running lightning as a hidden service is a great idea as well, this tutorial shows how to achieve something similar with the clearnet.
EDIT 3: You can achieve a similar result from using TOR

Small form factor for home server and Bitcoin node

Before I start, let me emphasize on the fact that this request is something probably quite unusual for this sub and I apologize if it doesn't belong here. If that's the case, please let me know.

What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.
I'm looking for a small, quiet and affordable computer which will run 24/7 in my house. The aim is to make it a personal server and a Bitcoin node (not for mining, just a node).
A Bitcoin node should run on hardware with good endurance, stable internet connection, a large storage and that can run for a long period of time.

What is your maximum budget before rebates/shipping/taxes?
300€

When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.
Anytime during this summer.

What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc)
I'm not sure if it's the right place but here are my criteria:

Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?
France

If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.
I will use this computer as as server so via SSH after the install. I already own some spare monitors and peripherals.

Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?
No

Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)
As said earlier, I need a large storage for the Bitcoin node. I'm thinking about a 2TB NAS HDD so it can last for a very long time. The NAS variant of HDD is probably the one which suits my needs the most as the disk will be very frequently accessed and will run 24/7.

Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?
Mini ATX if possible. I'd prefer a small form factor. The most important part of the case is its protectiveness, the rest is not important.

Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?
No, I will install a linux distro.

Extra info or particulars:

I found the Odroid H2 and Odroid HC2 which fit my needs perfectly but they are either sold out, unavailable or have insanely high customs fees. Also I checked Intel NUCs but I'm not sure it is what I need, especially for the price. A Raspberry Pi is not a good choice because of the storage capabilities (connected by USB 2.0) and limited RAM.
I considered building a machine myself but I'm not sure which components to use, and where to buy them. This is why I came here and this is something I'm still open to, if the price is not too high.

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)
http://faucet.burst-coin.es
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?
Main website: https://www.burst-coin.org/
Reddit: https://www.reddit.com/burstcoin and https://www.reddit.com/burstcoinmining/
Burstforum.net: https://www.burstforum.net/
Getburst forum: https://forums.getburst.net/

Other ways to talk to the community:
Discord: https://discordapp.com/invite/RPhpjVv
Telegram (General): https://t.me/burstcoin
Telegram (Mining): https://t.me/BurstCoinMining
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.

INFO
https://github.com/biblepay/biblepay-evolution/blob/masteBuildBiblePay.txt
INSTALL COMMANDS
apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler apt-get install git apt-get install curl build-essential libtool autotools-dev automake pkg-config python3 bsdmainutils cmake sudo add-apt-repository ppa:bitcoin/bitcoin sudo apt-get update sudo apt-get install libdb4.8-dev libdb4.8++-dev git clone http://github.com/biblepay/biblepay-evolution prefix=x86_64-pc-linux-gnu cd biblepay-evolution/depends make -j4 # Choose a good -j value, depending on the number of CPU cores available cd .. ./autogen.sh #Note: if echo `pwd` does not return your working directory, replace it with your working directory such as /biblepay-evolution/ ./configure --prefix `pwd`/depends/x86_64-pc-linux-gnu make # See more here: #https://github.com/biblepay/biblepay-evolution/blob/mastedoc/build-unix.md 

SWAP FILE
NOTE: if server is 1GB RAM, before running last command "sudo make", set up a swap file
free #check if swap is 0 dd if=/dev/zero of=/vaswap.img bs=1024k count=1000 mkswap /vaswap.img swapon /vaswap.img free #check if swap is 1024 sudo make 

RUN COMMAND LINE
cd src ./biblepayd -daemon 
OR
RUN GUI
Your GUI program will be located in: /biblepay-evolution/src/qt
./biblepay-qt 
You can also run it in the background (to free up your terminal) if you call it with:
./biblepay-qt & 
To start mining, instructions are the same as for Windows: Go to Tools -> Debug Console
Execute this command (to start mining with 8 threads)
setgenerate true 8 
From there you can use all other commands such as getmininginfo, getwalletinfo, etc. Execute help command to get the list of all available commands.
Note: GUI will be built automatically only if you meet the requirements for qt library, i.e. make sure you ran this line before compiling:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler 
BIBLEPAY is now Running!

SETUP CONFIG
Stop BiblePay and set up the config file to get starting nodes to sync with and enable mining:
./biblepay-cli stop cd ~/.biblepayevolution/ vi biblepay.conf addnode=node.biblepay.org gen=1 genproclimit=1 
Escape Key + : (Colon Key) + w + q + Enter (saves file and quits)

addnode --- adds a node to the list of nodes to connect to gen=1 --- turns on mining genproclimit --- sets number of threads to use when mining

Run BiblePay again and fully sync with network
cd ../biblepay-evolution/src ./biblepayd -daemon ./biblepay-cli getinfo 

USEFUL COMMANDS
./biblepay-cli help ./biblepay-cli getaccountaddress "" ./biblepay-cli getinfo ./biblepay-cli getmininginfo ./biblepay-cli setgenerate true 8 ./biblepay-cli sendtoaddress "insertAddressHere" 777 "" "" true ./biblepay-cli stop ./biblepayd -daemon top #CPU usage q to quit 

MINING THREADS: To change number of threads to use up for mining
a. Edit home/yourusername/.biblepayevolution/biblepay.conf file:
genproclimit=X 
and restart BiblePay -or- b. Menu >> Tools >> Debug Console >> Type command:
setgenerate true X 
(Replace X with number of threads Use top command to view CPU usage)

POOL
NOTE: To use the pool you must now use the external miner, not the wallet miner https://whitewalr.us/2019/biblepay-nomp-pool-mining.html
  1. Set up an account on pool website: https://pool.biblepay.org/
  2. Create Worker Username(s) - Workers tab >>> Add
  3. Enable pool and add Worker Username in ~/.biblepayevolution/biblepay.conf file, add these lines and save:
    pool=https://pool.biblepay.org workerid=insertWorkerUsernameHere
4. Restart BiblePay
./biblepay-cli stop ./biblepayd -daemon 
Setup Auto-Withdraw Navigate to Account >>> Account Settings >>> Verify your BBP Receiving Address >>> Click Authorize-Auto-Withdraws

UPDATE:

### Turn off/stop BiblePay
cd /home/yourname/biblepay-evolution/src ./biblepay-cli stop 

### Pull down latest Biblepay code and build it
cd /home/yourname/biblepay-evolution git pull origin master sudo make 

### Turn BiblePay back on and check version number
cd src ./biblepayd -daemon ./biblepay-cli getinfo ./biblepay-cli setgenerate true 8 

UPDATE IN ONE COMMAND:
./biblepay-evolution/src/biblepay-cli stop ; cd && cd biblepay-evolution/ && git pull origin master && sudo make && cd src && ./biblepayd -daemon && sleep 90 && ./biblepay-cli getmininginfo 
Note: the ";" says do this after, regardless of the outcome Note: && says do this after only if previous command finished with no errors

SPEED UP COMPILE:
To speed up the compile time, add -j4 or -j8 after make. This way it compiles using 4 or 8 threads instead of just 1.
./configure LDFLAGS="-L${BDB_PREFIX}/lib/" CPPFLAGS="-I${BDB_PREFIX}/include/" sudo make -j8 
Reference: http://www.linux-databook.info/?page_id=2319

RSYNC stop biblepay from your nodes compile on your fastest machine then rsync with your machines only src folder is required
rsync -avuz /root/biblepay-evolution/src/ [email protected]:/root/biblepay-evolution/src/

How to get started on GPU mining on Pizza Pool (gpu.pizza) [Nvidia/linux/ClosedSource]

Sunday morining the 0xBitcoin Discord got a surprise from @0xPiZzA...
hi guys. i am 0x778, again! has it gone a long time and you miss me? 8^D= i wait two more weeks since last time, want to check you to see if you are ready for gpu and 0xBITCOIN. today i am ready to release Closed Source GPU Miner for everyone, works for my new Mining Pool name " PiZzA Pool " ! \o/ new pizzaminer is ALPHA software : means speed good but has bugs. Linux only OS. new pool PiZzA Pool also ALPHA but in testing now, available for your to try. credit system is counting. automatic payment, i am building it now. XD lets GO for best! i am not support Help with this software, please figure it out. i believe you can do it. PiZzA Pool going to donate 2% to 0xBITCOIN project / Infernal Toast who will make Open Source Gpu Miner in competition with pizzaminer and Prevail in Triumph. .o/\o/ when you ready, more info : http://gpu.pizza/ :heart: Have Fun, Love 0xBITCOIN 8^D= ~~ 0xPiZzA :heart: 
GPU mining!!!
PiZzA pool - http://gpu.pizza/
Before we start...
THIS SOFTWARE IS CLOSED SOURCE
I DON'T OFFER ANY WARRANTIES ON THIS MINING SOFTWARE
USE AT YOUR OWN RISK
Yet the miner works and I've been paid by the pool (71.17318134 0xBTC):
https://etherscan.io/address/0x79c5BE8f4098208006C7940cF72dAE71738b39b6#tokentxns
1. Prepare your mining rig
Download required programs:
http://gpu.pizza/#download
https://www.ubuntu.com/download/desktop
https://rufus.akeo.ie/
Using this software is risky, but you can minimize the risk by planning. Ideally you want a sanitized GPU mining rig.
This means:
  • No private key!!!
  • No saved passwords!!!
  • No files you are not comfortable with losing!!!
Use this as a basic security audit if you have an existing GPU mining rig.
2. Download and Install Ubuntu
You can Google this.
I believe in you, you will figure it out. :-D
But get an .iso and use Rufus to make a bootable USB.
3. Install Nvidia Drivers
Don't download them from the Nvidia website. Use repositories instead. This guide worked for me: http://www.linuxandubuntu.com/home/how-to-install-latest-nvidia-drivers-in-linux
Make sure you are connected to wifi at this stage. The error message will not clue you into the fact that your internet is not working.
4. Run the pizzaminer software
Details are in the README.TXT. But essentially all you need to do is run the program. Make sure in properties it has permissions to exectute. Also run each miner in their own terminal instance.
http://gpu.pizza/download/pizzaminer-v0.0.1-alpha/README.txt
CUDA_VISIBLE_DEVICES=0 ./pizzaminer 0x0123AbC... CUDA_VISIBLE_DEVICES=1 ./pizzaminer 0x0123AbC... CUDA_VISIBLE_DEVICES=2 ./pizzaminer 0x0123AbC... CUDA_VISIBLE_DEVICES=3 ./pizzaminer 0x0123AbC... 
5. Configure Autostart
Inside the directory where pizza miner is create a file (autostart) that is executable and contains your payment address:
#!/bin/sh xterm -e -hold CUDA_VISIBLE_DEVICES=0 ./pizzaminer 0x0123AbC... & xterm -e -hold CUDA_VISIBLE_DEVICES=1 ./pizzaminer 0x0123AbC... & xterm -e -hold CUDA_VISIBLE_DEVICES=2 ./pizzaminer 0x0123AbC... & xterm -e -hold CUDA_VISIBLE_DEVICES=3 ./pizzaminer 0x0123AbC... & ... 
Then from Start>Startup Applications add the following task:
Name: Autostart pizzaminer Command: autostart (browse for file created above)
7. Optimization
v0.0.3 CPU optimization
Before the CPU was bottle necking the GPU utilization in certain cases. v0.0.3 fixes this and it's stable for me. With multiple cards on a Celeron G39XX you can expect a 50%+ boost in overall hash rate.
Overclocking (EXPERIMENTAL!!!)
This command should allow basic overclocking, monitor free initialization. Honestly haven't had much success in the overclocking department. Let me know if you do!
sudo nvidia-xconfig -enable-all-gpus -cool-bits=28 --allow-empty-initial-configuration 
6. Known Hashrates
GPU MH/s MH/s MH/s
Version v0.0.1 v0.0.2 v0.0.3
GTX 970 (40 MH/s) (55 MH/s) (75 MH/s)
GTX 1050 Ti (40 MH/s) (75 MH/s) (90 MH/s)
GTX 1060 (60-70** MH/s) (100 MH/s) (150 MH/s)
GTX 1070 Ti (90** MH/s) () ()
GTX 1080 Ti (140** MH/s) () (325** MH/s)
**unconfirmed
Please tell me your hashrates to add to this table!!!

Use the BTCP full Node on a Ubuntu 16.04 LTS from Terminal

In this post I want to show some use of the CLI BTCP wallet from linux terminal.
DISCLAIMER:
First of all, use this tutorial with small amount of BTCP, for example i used 0,01 BTCP, until you feel confortable with commands. An error can happen easily and as result you can loose your money. Be careful! Do it at your risk!
I consider you have already installed the wallet following this instructions:
https://github.com/BTCPrivate/bitcoinprivate
I use Ubuntu 16.04 LTS 64bit, but commands are similar for the windows client.
Open a terminal from your Ubuntu Desktop:
[email protected]:~$ 
type:
[email protected]:~$ ./BitcoinPrivate/src/btcpd --daemon 
you should see the message:
BTCP server starting 
This means the wallet is running in daemon mode.
to stop the node just typing:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli stop 
Answer:
BTCP server stopping 
You can also run the wallet in terminal, is nice to see it, let's try:
 [email protected]:~$ ./BitcoinPrivate/src/btcpd 
You will see the BTCP logo in text mode and the following info:
Thank you for running a Bitcoin Private node! You're strengthening the network and contributing to a social good. To ensure you are fully protecting your privacy when running BTCP, see . Block height | 340079 Connections | 8 Network solution rate | 8359387 Sol/s You are currently not mining. To enable mining, add 'gen=1' to your btcprivate.conf and restart. Since starting this node 1 minutes, 33 seconds ago: - You have validated 695 transactions! [Press Ctrl+C to exit] [Set 'showmetrics=0' to hide] 
See, you can also mine using the wallet! Nice! Just add gen=1 in the file btcprivate.conf. Probably you will never mine a coin, but still you to strenght the net, so, you can try if you want, then disable it when done:
Press CTRL and C to stop the server, then restart the server in daemon mode otherwhise you have to open a new terminal.
Let's find btcprivate.conf and other useful files:
[email protected]:~$ cd .btcprivate [email protected]:~/.btcprivate$ ls 
Answer:
blocks btcprivate.conf chainstate db.log debug.log fee_estimates.dat peers.dat wallet.dat 
You see here: btcprivate.conf and wallet.dat
Edit configuration file:
[email protected]:~/.btcprivate$ pico btcprivate.conf 
add gen=1 if you want to mine, then CTRL X and Y to save.
Restart the wallet....and....
Block height | 340091 Connections | 8 Network solution rate | 8211926 Sol/s Local solution rate | 0.0075 Sol/s Since starting this node 8 minutes, 5 seconds ago: - You have validated 684 transactions! - You have completed 1 Equihash solver runs. You are mining with the default solver on 1 threads. 
Congratulations! You are mining!
Now have a look to the wallet.dat file:
Nb: wallet.dat is your wallet!! If you delete it you will loose all your money!!!
wallet.dat is not encrypted, so, if you want to backup it i do as follows:
[email protected]:~/.btcprivate$ cp wallet.dat home/btcp/Desktop/wallet_btcp_back.dat 
Now you will find the wallet on your desktop. Zip it with an AES256 encryption and a strong password. Test if it works properly: extract it again and copy it in the directory, but before make an other copy of the wallet.dat file. Beware! I almost deleted the file once!
Nb: wallet.dat is your wallet!! If you delete it you will loose all your money!!!
Go back to your home directory, now, we want to play with our wallet:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli help 
if everything is running properly, you will see a list of commands like this:
z_exportwallet "filename" z_getbalance "address" ( minconf ) z_getnewaddress z_getoperationresult (["operationid", ... ]) z_getoperationstatus (["operationid", ... ]) z_gettotalbalance ( minconf ) z_importkey "zkey" ( rescan startHeight ) z_importwallet "filename" z_listaddresses z_listoperationids z_listreceivedbyaddress "address" ( minconf ) z_sendmany "fromaddress" [{"address":... ,"amount":...},...] ( minconf ) ( fee ) z_shieldcoinbase "fromaddress" "tozaddress" ( fee ) zcbenchmark benchmarktype samplecount zcrawjoinsplit rawtx inputs outputs vpub_old vpub_new zcrawkeygen zcrawreceive zcsecretkey encryptednote zcsamplejoinsplit [email protected]:~$ 
Nice! Wallet is running properly. Now try an other command: getinfo
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getinfo 
Answer:
{ "version": 1001251, "protocolversion": 180004, "walletversion": 60000, "balance": 0.00000000, "blocks": 340074, "timeoffset": 0, "connections": 8, "proxy": "", "difficulty": 167290.7158221716, "testnet": false, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000, "relayfee": 0.00000100, "errors": "" } [email protected]:~$ 
You see some useful info about your wallet/node:
blocks is the block heights, in this case is synced with the network. If not the number would be lower.
The wallet is connected to other 8 nodes, the balance is 0.00 BTCP
An other info command can be getblockchaininfo:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getblockchaininfo 
Answer:
{ "chain": "main", "blocks": 340074, "headers": 340074, "bestblockhash": "0000000145c0011d8e914f4ba68d1443c7ae0dd15bdf0bc300994dd5282710aa", "difficulty": 165971.1181999981, "verificationprogress": 0.9999992572690658, "chainwork": "0000000000000000000000000000000000000000000000000002e8314e4484da", "pruned": false, "commitments": 663480, 
we see syncing is almost finished:
"verificationprogress": 0.9999992572690658, (99,99999%)
Now test the wallet with command getwalletinfo
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getwalletinfo 
Answer:
{ "walletversion": 60000, "balance": 0.00000000, "unconfirmed_balance": 0.00000000, "immature_balance": 0.00000000, "txcount": 0, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000 } [email protected]:~$ 
Now we want to send some btcp to this wallet. First we need an address, get one using getnewaddress:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getnewaddress 
Answer:
b1Cabjwvcce7N8ea9Gxxxxxxxxxxxxxxxx [email protected]:~$ 
Send at this address some BTCP, i sent 0.01 for testing purpose using your ledger, or your wallet, then check if the transaction is done:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getwalletinfo 
Answer:
{ "walletversion": 60000, "balance": 0.00000000, "unconfirmed_balance": 0.01000000, "immature_balance": 0.00000000, "txcount": 1, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000 } 
Done! Unconfirmed balance is 0.01! Just wait some confirmations.
after a while:
"walletversion": 60000, "balance": 0.01000000, "unconfirmed_balance": 0.00000000, "immature_balance": 0.00000000, "txcount": 1, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000 
Now send the coins to a new address. I am using this command:
sendtoaddress "btcpaddress" amount ( "comment" "comment-to" subtractfeefromamount )
subtractfeefromamount parameter can be true or false
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli sendtoaddress "b1Nb42GoK9kmsxxxxxxxxxxxxx" 0.01 "" "" true 
Answer:
2c5d3d1a3b5eec414b721d3817487f53c5eebxxxxxxxxxxxxxxx [email protected]:~$ 
Now check the wallet:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getwalletinfo 
Answer:
{ "walletversion": 60000, "balance": 0.00999808, "unconfirmed_balance": 0.00000000, "immature_balance": 0.00000000, "txcount": 2, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000 } 
I sent BTCP to the same wallet, so now i have less BTCP because of the fees.
try more commands:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli listreceivedbyaddress 
Answer:
[ { "address": "b1Ep2wi2tUnKf433Vaxxxxxxxxxxxx", "account": "", "amount": 0.01000000, "confirmations": 6, "txids": [ "833533440a13c09fda6e90d0c5xxxxxxxxxxxxxxxxxxxxxxxxxxxxx" ] }, { "address": "b1Nb42GoK9kmsVZ9KPxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "account": "", "amount": 0.00999808, "confirmations": 1, "txids": [ "2c5d3d1a3b5eec414b721d3817487f53c5xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" ] } 
This is the list of all used addresses.
Now find the money and the address where they are: use listunspent
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli listunspent 
Answer:
[ { "txid": "2c5d3d1a3b5eec414b721d381748xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "vout": 0, "generated": false, "address": "b1Nb42GoK9kxxxxxxxxxxxxxx", "account": "", "scriptPubKey": "76a914c6bdf3bc8aedxxxxxxxxxxxxxxxxxx", "amount": 0.00999808, "confirmations": 6, "spendable": true 
Well done.
Other useful commands can be: dumpprivkey to extract the private key from an address
Be careful! Exposing your private keys will end in loosing your money
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli dumpprivkey b1Ep2wi2tUnxxxxxxxxxxx 
Obtaining the pvt key:
Kz29e62Bmxxxxxxxxxxxxxxxxxxxxxxx 
And now, swipe the private key using the command: importprivkey "btcpprivkey" ( "label" rescan )
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli importprivkey "Kz29e62Bmxxxxxxxxxxxxxxxxxxxxx" "" true 
Let's do a shielded transaction!
first, you must have a z_address:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli z_getnewaddress 
Answer:
zkEvCiVwgHb3NFi2ee9HGPjno2xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 
Check balaces, with also z_addres:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli z_gettotalbalance 
Answer:
{ "transparent": "0.00999808", "private": "0.00", "total": "0.00999808" } 
Now send some BTCP to the z_address. First, check where BTCP are:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli listunspent 
Output:
[ { "txid": "72f568d1ed51524b69f1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "vout": 0, "generated": false, "address": "b1LDhxBJxxxxxxxxxxxxxxxxxxxxxx", "scriptPubKey": "76axxxxxxxxxxxxxxxxxxxxxxxxxxxxxxe088xx", "amount": 0.00889808, "confirmations": 556, "spendable": true } ] 
Now, sent a little transparent amount to the shielded address we got before:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli z_sendmany "b1LDhxBJxxxxxxxxxxxxxxxxxxxxxx" "[{\"amount\":0.001, \"address\":\"zkEvCiVwgHb3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\"}]" 
Output:
opid-xxxxxxx-36c4-xxxx-beb2-xxxxxxxxxxxx 
Now your PC will work a while, it's CPU consuming...so...check:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli z_getoperationresult 
until you receive the answer:

Done! On my old PC it took 216.68 seconds!
Next will be a reverse operation, from Shielded address to transparent address. See you soon....
Play with your full node wallet and have fun.
Remember: these commands are almost the same in all the bitcoin based coins, so you also learnt how to use many other wallets!

Special Request: Build a PC with lowest Watt per FLOPS regardless of cost

The purpose of this PC build is to minimize power consumption but maximize processing speed. Here I used the metric FLOPS but I think clockspeed would be more practical. Do not consider financial cost of the parts, but do list reliable and reputable parts/brands. This will NOT be a bitcoin mining machine.
What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.
What is your maximum budget before rebates/shipping/taxes?
When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.
What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc)
Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?
USA. Yes Microcenter.
If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.
Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?
Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)
Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?
Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?
Extra info or particulars:

A helpful discussion about wallet security (esp. Electrum)

I was recently contacted via private message by a redditor who read a comment of mine about wallet storage (I assume this comment). I think there was quite a bit of useful information in it for other bitcoin beginners, so I am reposting it here in full (with permission). The redditor in question wanted to remain anonymous though.
I hope this is of use to some of you here!
From: Anonymous Redditor
I saw your post regarding your wallet storage and had a few noob questions if you don't mind.
My plan is similar to yours but I was unsure whether to use armory or electrum (electrum's seed creation scares me a bit).
You mentioned you have a bootable LINUX (ubuntu?) USB stick that you keep your wallet on....do you only boot this onto an always offline computer?
Do you use something like Truecrypt to further protect your wallet.dats?
Thanks for your time!
From: SanderMarechal
My plan is similar to yours but I was unsure whether to use armory or electrum (electrum's seed creation scares me a bit).
For me it is the other way around. Armory (and bitcoin-qt) scare me. Armory is just a wallet. It still needs bitcoin-qt running in the background. For me the problem is two-fold:
1) Size
bitcoin-qt (and armory) need to download the entire blockchain. That 13+ GB that takes hours to download and days to verify. And if you ever lose it, you need to do it again.
2) Random keys
armory and bitcoin-qt generate random private keys. You get 100. If you use a few (you use them when you send coins for example) then new ones are created. So, if you create an armory wallet and make a backup, that backup will have 100 keys. Then, if you make 33(!) transactions, your 100 keys are used up and you will have 100 different random keys. If someone then steals your computer (or your house burns down) then you cannot use your backup anymore. It only has the 100 old keys and none of the new keys. So you have lost all your bitcoins.
Why 33 transactions and not 100? Because of change addresses. If you have 10 BTC and send me 2 BTC then most wallets will create 2 transactions. 2 BTC from your old addres to me, and 8 BTC from your old address to a new (random) address. This process costs 3 private keys. 2 keys for the transactions and 1 key to create a new address.
This means that after every few dozen transactions you need to refresh your backup so it has the newer keys. For me that is impractical. It means that I need to keep my backup close by because I often need it.
Electrum does not have this problem. The seed solves this. Private keys are not random but are created from the seed. If you have the seed then you have, by definition, all the private keys you will ever need. Your backup can never be out-of-date. This is easy for me. I save the seed in a file, encrypt it, put it on an USB stick and give copies to a few family members who have safes in their homes.
If my computer is ever stolen, or my house burns down, I can go to a family member, decrypt the seed file and use the seed to restore my electrum wallet. Even if that USB stick is 10 years old.
You mentioned you have a bootable LINUX (ubuntu?) USB stick that you keep your wallet on....do you only boot this onto an always offline computer?
It depends on how secure you want to be. For maximum security, keep the computer always offline. But if you want to spend the bitcoins from your wallet, you will need to be online.
I use the USB stick for my savings account. It only receives coins and I do not send. So I do not need to boot up my USB stick. I have created a second wallet on blockchain.info that I use for day-to-day transactions. All BTC I receive goes to my blockchain account. Then I transfer a part of that to my savings account and only keep a bit of change that I need in the blockchain account.
Do you use something like Truecrypt to further protect your wallet.dats?
No. Electrum does not have a wallet.dat. It has the seed. I simply copy the seed to a TXT file and encrypt it using GPG and symmetric encryption. Example:
gpg --armor --symmetric --cipher-algo AES256 seed.txt 
Make sure you use a password that is strong and that you cannot forget! If you need to write the password down on paper and your house burns down, then you cannot decrypt the seed anymore!
From: Anonymous Redditor
Forgive the naivety here: Correct me if I'm wrong - The safest way to generate your wallet seed is on an offline computer correct? So, theoretically, generate the seed on an offline-only computer, copy to txt...encrypt. back up on multiple USB's. Then on your online computer, load electrum and import Seed?
Thanks so much for the thorough explanation! I'm a potato when it comes to reddit's bitcoin tip bot. Send me an address - would like to send some internet magic money your way.

Not quite. The risk with an online computer is malware and people breaking in. If you generate the seed on an offline computer and then move it to an online computer, you don't really take that risk away. You still have your wallet on an online computer which you use for day-to-day work and which is exposed to hackers and malware.
I suggest you make two wallets. One wallet is your "savings" wallet. You can use the USB stick Linux for this. Generate the wallet offline, backup and encrypt the seed onto multiple USB sticks and note down the bitcoin address somewhere so you can transfer funds to it. The only time you should use the USB stick to go online is when you want to transfer funds out of your savings wallet.
The, on your normal computer (or your smartphone if you prefer), create a second wallet using a different password. This is the wallet you keep only a little money in for your day-to-day transactions. Note down the seen, encrypt (with a different password than you used to encrypt the seed from your savings wallet) and add it to the USB keys. You can use Electrun for this second wallet as well, but you can also use something different. I use a blockchain.info wallet for my day-to-day expenses.
Whenever you have a larger amount of bitcoins in your day-to-day wallet, transfer some to the wallet on the USB stick. You don't need to boot up the USB stick for this. You only need the address you wrote down.
When you want to spend a large amount of money, boot up from the USB stick and transfer coins from your savings wallet to your day-to-day wallet. Reboot into your normal computer and use the day-to-day wallet to pay for what you wanted to buy.
The core of the issue is simple: Don't store a lot of money in a wallet on a computer that you use a lot. Computers that are used a lot get attacked a lot. Simple :-)

You are awesome:) Thank you again for the insight! Sent some your way.

Your welcome. And thanks for the coin!
From: Anonymous Redditor
Last question(s) (I promise)...
Would a netbook like this be appropriate to 1)dban 2) boot up via USB ubuntu and 3) create the electrum seed?
This would of course never go online, be backed up and encrypted, etc.

Thanks again.
From: SanderMarechal
I don't know. You would be better off asking this on www.ubuntuforums.org for example. I don't know if that computer's hardware is compatible with Ubuntu. Speed-wise the bottleneck will be the USB stick and not the CPU or memory. USB sticks are much slower than hard drives.
Note that you don't have to buy a computer for this. You can use the computer you already have and still run Ubuntu off an USB stick for your Electrum wallet.
What I said in my previous post about not using your day-to-day computer for your wallet, with that I mean the operating system and software. Not the hardware. Unless you're afraid someone put a hardware keylogger inside your computer :-)
From: Anonymous Redditor
Fascinating!
My tin foil hat is in full effect:) Thanks again for your time and patience.
From: SanderMarechal
Your welcome. Have fun with bitcoin!
Oh, I have a question for you now. Would you mind if I repost our entire private conversation here to /BitcoinBeginners? I think other redditors there would also be interested. And if I can repost it, do you want your username in there or should I replace it with "Anonymous Redditor" or something?
From: Anonymous Redditor
You can certainly repost it! And yes, if you wouldn't mind removing the username I would very much appreciate it.
Thanks for asking btw!
Anyway, I hope this is useful for some people out here.
