Issue upgrading my bitcoin node

Hello,
I'm trying to update my current node (v0.18.1.0). I'm running my node on Mac using an external HD.
Everything is on my HD except for the bitcoin.conf file and the Bitcoin Core icon in my Applications folder.
I was able to launch my node using the icon on my Application folder (bitcoin-qt) or using the command line (bitcoind)
Since I downloaded the new version (v0.19.0.1), I have the following issue:
When I launch my node using the icon on my Application folder (bitcoin-qt) everything is fine and the new version is running (using the data in my external HD), but when launch the node using the command line (bitcoind), it still launch the old version.
Is there a separate update from bitcoind? I've done some research online but I didn't find anything helpful.
Thank You!!!
***EDIT***
I have downloaded "bitcoin-0.19.0.1-osx64.tar.gz" which include the executable for bitcoind, bitcoin-cli, etc and replace the old ones by the new ones and everything looks fine!

[PSA] Dogecoin Wallet version 1.4 released. You must update.

WARNING: DO NOT send your wallet.dat file or dogecoin folder to anyone. There have been reports of people offering to help others by asking them to send their files to them so they can help. DO NOT do this. Scam attempt picture
Always encrypt your wallet! I can't express this enough. You should use a strong password longer than 15 characters. This password should contain numbers, symbols, and some capitalization! There is no need to have your wallet open 24 hours a day. Open it only when you need it. See - 'Getting Started' on the side bar.
This entire post has been written to be as close to ELI5 (Explain it like I'm 5) as possible - By request! If anyone wants to add/fix/correct anything in this message, please send a message to the mods <<-- Click blue text.
All blue text in this post can be clicked on. The blue text is a link to a picture, site or download file.
A very important message/reminder below.
25 Jan 1.5 pre-releases have started.
http://www.reddit.com/dogecoin/comments/1uhpwf/dogecoin_for_mac_14_topic_thread/
OLD VERSIONS The 1.4 update for the dogecoin wallet has been released. This update addresses the block chain error that occurred. This update is mandatory meaning you have to do this update. Also further down the page you can read up about the block chain. You MUST make sure you're on the correct block chain and the old block chain has been removed.
For a Windows computer the version must be 1.4. - 1.4.1 just released! See below
For a Apple Mac Computer the version must be 1.4
Download links:
[Windows Download Link](https://github.com/dogecoin/dogecoin/releases/download/1.4/dogecoin-qt-v14-Win.zip) <<--Click to start download
Windows Download Link 1.4.1 UPDATED 19JAN
Mac Download Link <<--Click to start download
Mac users can join this thread if there are any problems
Android (phone): Please see This post
To update, simply download the new version from the download link above. Open the downloaded file and extract the contents of the downloaded file into any new folder or location on your computer. If you put the files into a folder you can name the folder anything you want but make sure you remember that this is the latest version of the software.
You don't have to remove your folder containing the old version of the wallet. You can place it in a folder called 'Old versions of dogecoin wallet' if you like.
Now you can click on the Dogecoin icon contained in the new folder to open your version 1.4 wallet.
What happens if I get an error when I open the new wallet?
An error was reported called "11DbException"
If this happens Download this file and place it in the same folder as your updated wallet. Open the file you just downloaded called "Dogecoin OPEN' and wait. This might take 2 or 3 minutes.
Also jtlarousse has found a solution that worked on Windows. Please follow carefully and make backups before starting.
Reebzy might have found a solution for Apple Mac
Blockchain fork 101: The block chain is a ledger or document created containing every transaction that has ever happened. This file can be quite large. Bitcoins ledger is over 15GB. At some point this document/ledger split into two separate documents known as a fork.
How do I know if I am on the right block chain?
Go to your newly updated dogecoin wallet and open it. Click on Help>>Debug next Observe the current block number
*Note the example numbers in the pictures might be out of date by the time you read them
Now go over to http://dogechain.info/chain/Dogecoin . This website is the official Dogecoin blockchain website. Check the block number they're reporting
The number you found in your wallet and the number reported on the website should close. There might be a difference of 100 blocks depending on when you last refreshed your wallet or how long it took for you to get from one step to the next step in this guide and if the dogechain website is lagging.
I'M NOT ON THE CORRECT BLOCK CHAIN
My numbers are very different. How do I get back onto the right block chain?
IMPORTANT
For windows:
1)Close down the Dogecoin wallet client.
2)Go to your data folder: C:\Users[your windows log-in name]\AppData\Roaming\DogeCoin
3)Delete the Dogecoin.conf file. Do not delete the wallet.dat file!
4)Download this update file and place it into the Dogecoin folder where the other file was deleted.
For Apple Mac:
1)Close down the Dogecoin wallet client.
2)Go to your data folder: ~/Libarary/Application Support/Dogecoin
3)Delete the Dogecoin.conf file. Do not delete the wallet.dat file!
4)Download this update file and place it into the Dogecoin folder where the other file was deleted.
Next visit this post by Netcodepool for instructions on how to manually download the correct block chain and install it.
Much Thanks. 
Edit: Some posts were removed from this thread. To limit confusion.
Check this post for details about mining pools that were/are using the wrong fork.
Did you send coins only to find out you're on the wrong chain? See this post to get them back
An Apple Mac support thread has been made by voidref (The mac developer). If you're having troubles please see this thread
Some shibes have reported their wallets wont sync. Please check to make sure your firewall, antivirus, malware scanner or similar programs are not blocking it the wallet. You can add rules to these programs to allow the wallet to make contact with the internet. It's not advised but possible to also disable the software for a short amount of time. Don't forget to enable the software again afterwards.

Bitcoin 2 Core v.2.2 Wallets Released!

Now available for download at https://www.bitc2.org/#wallets and https://github.com/BITC2/bitcoin2/releases
Version 2.2 Change log:
Updating your Bitcoin 2 Core wallet to this version is mandatory. That includes upgrading all your Masternodes. After enough nodes have upgraded to this version, a new staking protocol will be activated and the old nodes that fail to upgrade their wallet before that will end up forking to the wrong chain. Estimated time of this protocol upgrade is between August 21 - August 24 2019. As soon as possible.
To update, you just need to download the archive, stop your wallet and let it fully shutdown, and then copy the executable files in the bitcoin2-bin folder to replace the ones you had installed already.
After upgrading your Masternode and your desktop wallet, you should go in the Masternodes tab on your controller wallet and click to Start the upgraded Masternodes.
Binaries for a couple of platforms that are less used are still to be compiled.

Dogecoin Core 1.7.0 released - Check in here for all info you need

Hi shibes!
The Dogecoin developers are proud to announce the final version of Dogecoin Core 1.7! After lots of coding, testing and swearing this is the next version of our reference client. It brings Dogecoin one big step forward on the technical side of things, with moving to the Bitcoin 0.9 codebase.
The full release notes are available here: https://github.com/dogecoin/dogecoin/releases/tag/v1.7.0
TL;DR of the release notes
Is this mandatory? No, you can stay on 1.6 if you want for now. This update adds quite a few new features you'd miss out on.
How to update?
  1. Backup your wallet! This is very important! Go to File -> Backup Wallet, and save this file in at least two safe places for a good backup.
  2. Exit the client you're running now.
  3. Install the update
    1. For Windows, use the setup.exe to update. If you are using the new 64bit version you'll need to uninstall 1.6 afterwards.
    2. For Mac just overwrite the version you currently have in you Applications folder.
    3. For Linux you'd overwrite your current dogecoin-qt binary with the new one.
  4. Start the client. That's it :)
About going back to 1.6 Once you go to 1.7 there is no easy way back to 1.6. That's why it's important to have a backup of your wallet. Just in case. Be aware that a backup goes out of date after 100 transactions! Several people have been running 1.7 for a while now and see no problem with it, so you probably don't want to go back anyway ;)
Downloads (Listing here this time to make it easier to find)
Changes from RC1
Staying up to date If you want to easily stay up to date with releases, you can subscribe to the mailing list right here: http://sourceforge.net/p/dogecoin/mailman/dogecoin-releases/ That's especially advised if you are a service provider!
General comments For anyone running an exchange, please also note that in light of the 51% attack against Reddcoin last night, the Dogecoin developers now recommend a minimum of 10 confirmations for payments into an exchange.
Thanks Thanks to everyone who contributed so far! Especially leofidus-ger, rnicoll and patricklodder, who have done by far the most of the work for this release. But of course thanks to everyone else who contributed, may it be advice or code or whatever. Also thanks to the Bitcoin developers. And of course thanks to the Dogecoin community! You are what makes it fun to work on all this ;)

such beginner shibe thread wow how to get coin

 how to shibecoin v rich in minutes much instruct so simple any doge can do 

START HERE

UPDATE 1/21/14: I'm not updating this guide anymore. Most of the steps should still work though. See the wiki or check the sidebar for updated instructions.
Before you do anything else, you need to get a wallet. Until there's a secure online wallet, this means you need to download the dogecoin client.
Now open the client you just downloaded. You'll be given a default address automatically, and it should connect to peers and start downloading the dogechain (aka blockchain in formal speak). You'll know because there will be a progress bar at the bottom and at the lower right there should be a signal strength icon (TODO: add screenshots).
If you've waited 2 or 3 minutes and nothing is happening, copy this:
maxconnections=100 addnode=95.85.29.144 addnode=162.243.113.110 addnode=146.185.181.114 addnode=188.165.19.28 addnode=166.78.155.36 addnode=doge.scryptpools.com addnode=doge.netcodepool.org addnode=doge.pool.webxass.de addnode=doge.cryptopool.it addnode=pool.testserverino.de addnode=doge.luckyminers.com addnode=doge.cryptovalley.com addnode=miner.coinedup.comdoge addnode=doge.cryptoculture.net addnode=dogepool.pw addnode=doge.gentoomen.org addnode=doge.cryptominer.net addnode=67.205.20.10 addnode=162.243.113.110 addnode=78.46.57.132 
And paste it into a new text file called dogecoin.conf, which you then place into the dogecoin app directory.
Now restart your qt client and the blockchain should start downloading in about 1-2 minutes.
Once it finished downloading, you're ready to send and receive Dogecoins!

GETTING COINS

Decide how you want to get Dogecoin. Your options are:
I'll go into detail about each of these. I'm currently writing this out. I'll make edits as I add sections. Suggestions are welcome.

MINING

Mining is how new dogecoins are created. If you're new to crypto currencies, read this. To mine (also called "digging"), a computer with a decent GPU (graphics card) is recommended. You can also mine with your CPU, but it's not as efficient.

GPU MINING

These instructions cover only Windows for now. To mine, you'll need to figure out what GPU you have. It'll be either AMD/ATI or Nvidia. The setup for both is approximately the same.

Step One: Choose a pool

There's a list of pools on the wiki. For now it doesn't really matter which one you choose. You can easily switch later.
NOTE: You can mine in two ways. Solo mining is where you mine by yourself. When you find a block you get all the reward. Pool mining is when you team up with other miners to work on the same block together. This makes it more likely that you'll find a block, but you won't get all of it, you'll have to split it up with others according to your share of the work. Pool mining is recommended because it gives you frequent payouts, because you find more blocks. The larger the pool you join, the more frequent the payouts, but the smaller the reward you get.
Over a long period of time the difference between pool and solo mining goes away, but if you solo mine it might be months before you get any coins.

Step two: Set up pool account

The pool you chose should have a getting started page. Read it and follow the instructions. Instructions vary but the general idea is:
When you're done with this, you'll need to know:

Step three: Download mining software

For best performance you'll need the right mining software.
Unzip the download anywhere you want.

Step four: Set up miner

Create a text file in the same folder as your miner application. Inside, put the command you'll be running (remove brackets).
For AMD it's cgminer.exe --scrypt -o stratum+tcp://: -u -p
For Nvidia it's cudaminer.exe -o stratum+tcp://: -O :
Substitute the right stuff in for the placeholders. Then on the next line of the text file type pause. This will let you see any errors that you get. Then save the file with any name you want, as long as the file extension is .bat. For example mine_serverName.bat.

Step five: Launch your miner

Just open the .bat file and a command line window should pop up, letting you know that the miner is starting. Once it starts, it should print out your hash rate.
If you now go to the pool website, the dashboard should start showing your hashrate. At first it'll be lower than what it says in the miner, but that's because the dashboard is taking a 5 minute average. It'll catch up soon enough.
NOTE: A normal hashrate is between 50 Kh/s up to even 1 Mh/s depending on your GPU.

You're now mining Dogecoins

That's it, nothing more to it.

CPU MINING

CPU mining isn't really recommended, because you'll be spending a lot on more on power than you'd make from mining Dogecoin. You could better spend that money on buying Dogecoin by trading. But if you have free electricity and want to try it out, check out this informative forum post.

Trading

Trading has been difficult so far, but Dogecoin just got added to a few new exchanges. If you don't have a giant mining rig, this is probably the best way to get 100k or more dogecoins at the moment. I'll write up a more complete guide, but for now check out these sites:

Faucets

Faucets are sites that give out free coins. Usually a site will give out somewhere between 1 and 100 Dogecoin. Every site has its own time limits, but usually you can only receive coins once every few hours, or in some cases, days. It's a great way to get started. All you do is copy your address from the receive section of your wallet and enter it on some faucet sites. Check out /dogecoinfaucets for more. If you go to each site on there you might end up with a couple hundred Dogecoin!

Begging

This method is pretty straightforward. Post your receiving address, and ask for some coins. Such poor shibe. The only catch is, don't do it here! Please go to /dogecoinbeg.

Tips

At the moment there are two tip bots:
Other redditors can give you Dogecoin by summoning the tip bot, something like this:
+dogetipbot 5 doge
This might happen if you make a good post, or someone just wants to give out some coins. Once you receive a tip you have to accept it in a few days or else it'll get returned. Do this by following the instructions on the message you receive in your inbox. You reply to the bot with "+accept". Commands go in the message body. Once you do that, the bot will create a tipping address for you, and you can use the links in the message you receive to see your info, withdraw coins to your dogecoin-qt wallet, see your history, and a bunch of other stuff.
As a bonus, so_doge_tip has a feature where you can get some Dogecoins to start with in exchange for how much karma you have. To do this, send the message "+redeem DOGE" to so_doge_tip. You'll need to create a tipping account if you don't have one.
If you want to create a tipping account without ever being tipped first, message either of the bots with "+register" and an address will be created for you.

Run a 0.14 Full-Node on RaspberryPi3 Pruned(less than 16GB SD needed)

Hi!
Happy if this guide helps you.
Tip if you want: 19656Uwdwko5RjtnuwQENpjBwE3ChzD59v
UPDATE 04/06/17
Add 'uacomment=UASF-SegWit-BIP148' into your bitcoin.conf if you want to signal UASF.
UPDATE 03/13/17
ADDED a tl;dr; Version at the end of this Post.
UPDATE 03/12/17:
Just to test it - I reinstalled all on 8GB SD and it works as well. But maybe you should use at least 16GB for the beginning.
Using a 128GB card for the first version was a little bit stupid - so I reinstalled everything on a 8GB SD card. Including Linux and a pruned blockchain - and it works.
I used prune=550 and Jessie Lite (headless / command line) - without wallet and gui.
The SD is almost full, but it works so far
I also updated the whole manual a bit to make things more clear. Thank you for all your feedback!
Just started my Bitcoin Node today and wanted to share the way I did it with people who are interested in running their own full node. It took some time to write everything down - hopefully correct so far.
I am sure, many people around bitcoin are way more informed and educated as I am - I am the noob. So I wrote this manual to help users like me - noobs, to get started with a cheap, simple bitcoin node on raspberry pi.
Have fun!
I wanted to get my Raspberry Pi 3 working as a node to support the network. Actually the process of installing and running the node was more or less easy - but for Noobs (like I am) it might be a bit tricky to start the whole thing, because there are different ways.
Did you - like me - think you would need +120GB on the raspi, external USB HDD to be a full node? You won't!
If you have a Raspberry and you know what Bitcoin is, I guess, you are a little bit aware of linux, networks and of course bitcoin - so I won't go into detail too much.
This guide is just a little helper to get a full node running on your raspberry pi. Thanks to the help of the nice people in this sub and of course the documentation by the developers, I got it working - and of course also special thanks to raspnode.com - as I followed their tutorial to start - I went some other ways here and there - so please read carefully.
For the Part 2 I would suggest to have http://raspnode.com/diyBitcoin.html open and read through my manual.
I split the tutorial in 2 Parts - PART ONE is about installing the client on your PC and downloading the Blockchain.
PART TWO is about the setup of the raspberryPi and transferring the pruned blockchain to the pi and run it as a full node!
The first thing to be aware of is: You actually need to download the whole blockchain to get this working - if you already have your bitcoin client synced on the PC / MAC great you can reuse it!
Now you might think "but you said less than 16GB in the title!"
Yes, but the good thing is you won't need to download it on your Raspberry, neither you need to sync it completely on your raspberry which took ages (weeks!) before. When you finished this Guide, you will just have a max. 4GB Blockchain on your Raspberry Pi - but it still is a full node! The magic word is Pruning.
Maybe even a 8GB SD Card works just fine including Linux (jessie lite)!
So, if you already have a full node on your PC - Great you can almost skip PART ONE - BUT have at how to Prune in PART ONE if you don't know about it.
For PART TWO you'll need a Raspberry Pi 2 or 3 (I used 3) min. 8GB (works also) or better 16GB SD Card. (I used a 128GB for the first version of this manual - which is way too big)

PART ONE

This is the manual how to get started on you PC / MAC / Linux (I did it on Win7)
Go to: https://bitcoin.org/en/download and download the core Client for your Machine (I used win64).
Install it and configure it to save the Blockchaindata to the directory of your choice - so instead getting 120GB on your C drive, I would suggest to download it to another place like a USB drive.
You can set this up during the install. Standard folder for the blockchain folder is "%APPDATA%\Bitcoin" on Windows.
or you can do it after the install by creating a bitcoin.conf file inside your installation folder / or %APPDATA%\Bitcoin and add
datadir=l:\yourfolder
to the file. Line by line.
By the way here you could also just add dbcache - to use more memory to speed up the process a bit:
dbcache=4096
if you don't want to use the settings inside the program. (you can also set this inside the program under settings! If you have this inside the bitcoin.conf you will see the amount you set there from inside the program - it overrides the values)
You can check inside the windows client under settings, if you can see a manual dbcache is set by having a look at the left footer area. When your dbcache value shows up, everything is fine.
So the Blockchain download process will take time - maybe a few days! Depending on your machine, internet connection and HDD.
The Blockchain is huge as it contains every single transaction of the past until today. You won't need to keep your PC running all the time, you can turn it off and on and it will resync automatically when you start bitcoin-qt.exe!
Make sure to close the client always via "quit" - ctrl+q.
After you have your bitcoin core installed, the blockchain downloaded and synced - you are ready to PRUNE!
First - close the Client and let it close smoothly. After it is really closed you can follow these steps:
By pruning, your blockchain will dramatically shrink. From 120GB to just a few GB.
Be aware, that you will lose your Downloaded Blockchain as pruning will erase a big chunk of it! If you have enough space, you could of course keep the full blockchain saved somewhere on another HDD.
You can prune by editing your bitcoin.conf file by adding:
prune=550
I used prune=1024 - not sure where the differences are right now (min. prune=550). (for my 8GB version I used 550! I suggest to use this.)
Save the bitcoind.conf file and restart your windows client.
It will now clean up the Blockchain. So just the latest blocks are saved. The client should start without any problems. Maybe it takes some time to prune the blockchain data.
Check if everything works normally (the client opens as usual, you can see an empty wallet) than close the client.
Inside the Bitcoin Folder, you'll find two folders called:
blocks chainstate
those are the interesting folders containing the important data (now pruned) - and we will transfer those two to the raspberry later!
Now you are good to start the raspi transfer explained in the next part.

PART 2

Here is what I did:
1) I installed Raspian Pixel (https://www.raspberrypi.org/downloads/raspbian/) using a 128 GB SD - which is not needed because of "Pruning" - I think a 16GB card might work, too! (You can also install Raspian Jessie Lite - which saves you even more space, as it runs headless - only command line) (Updated: It is better to use Jessie Lite to save a lot of space - when you are fine with only command line)
2) I followed partly this tutorial to get everything running and setup:
http://raspnode.com/diyBitcoin.html
Please have a look at it - I have copied the Headlines in capitals to let you know what I did, and what I skipped.
On Tutorial Page: Start with RASPBIAN (OPTIONAL) CONFIG OPTIONS.
Set You RasPi up including "EDITING FILES" to save your Layout at the tutorial page and come back here.
I skipped the CONFIGURE USB AND SET AUTOMOUNT process, as we are going to use PRUNING to reduce the 120GB to a tiny filesize - so USB Devices are not needed here!
It was necessary to ENLARGE SWAP FILE to install bitcoin core - otherwise it didn't went through which ended in a frozen raspi.
So have a close look by following the raspnode tutorial at: ENLARGE SWAP FILE.
I have my raspi running via cable to router - but you can also WiFi setup everything described under NETWORKING ON THE RASPBERRY PI.
Now comes the interesting part: Follow the steps at DOWNLOADING BITCOIN CORE DEPENDENCIES - they work fine for 0.14.0 too. Git should be on Board already when you installed Pixel - otherwise you would need to install it.
sudo apt-get install git -y (only jessy lite)
I skipped the next command lines - as I don't use bitcoin-qt wallet. If you want to use it as wallet - do the step.
mkdir ~/bin cd ~bin
Now you are in the folder you want your bitcoin core data be downloaded to via git. I didn't Downloaded the Berkeley Database source code - so I also skipped the whole next command lines
[email protected]~/bin$ wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz [email protected]~/bin$ tar -xzvf db-4.8.30.NC.tar.gz [email protected]~/bin$ cd db-4.8.30.NC/build_unix/ [email protected]~/bin/db-4.8.30.NC/build_unix$ ../dist/configure --enable-cxx [email protected]~/bin/db-4.8.30.NC/build_unix$ make -j4
and went on with "INSTALLING BITCOIN"!
I followed the first part but instead downloading 0.13 I took of course the latest version:0.14
git clone -b 0.14 https://github.com/bitcoin/bitcoin.git cd bitcoin ./autogen.sh
this might take some time to start.
If you have trouble with hanging RESOLVING DELTAS - just restart the Raspberry Pi and remove the bitcoin folder inside /~bin using
rm -rf bitcoin
this command will delete the folder and you can reuse
git clone -b 0.14 https://github.com/bitcoin/bitcoin.git

For some reason RESOLVING DELTAS is a common problem with different downloads - so just retry it and at least after 3 times it should work!

as I didn't use the GUI/ Wallet, I ran
./configure --enable-upnp-default --disable-wallet
as I don't need the wallet functionality.
I didn't need to use "MAKE" which saves you maybe up to 2.5 hours.
instead you can just go ahead with:
sudo make install
(If I am wrong in doing so - please let me know)
The install takes some time - and just a heads up: when it gets stuck somewhere - just redo the installation process - it took three times to went through - stuck at some processing.
After the installation took place you can finally get your Raspberry Pi Node running in no time!
To test if the the installation went through - you can just start bitcoind using:
bitcoind &
than check if everything is working so far:
bitcoin-cli getinfo
after a few seconds you should see version: etc...
if not, something went wrong. Try to redo the steps in the raspnode tutorial.
(don't give up if it failed - retry! Ask your questions here)
IMPORTANT: you need to stop bitcoin on your raspberry now!
bitcoin-cli stop
If you don't need an external USB Drive - what I hope - as we are going to use pruning just go ahead and skip the USB part and create a file inside (or follow the raspnode tutorial on how to setup the USB drive):
cd .bitcoin
sudo nano bitcoin.conf
and enter the exact same pruning size you have used on your Desktop Machine to prune. I used 1024 but the minimum is 550. (used 550 for the 8GB SD card on PC and Raspberry)
prune=550
That's it for the raspi.
update: To signal UASF enter in a new line:
uacomment=UASF-SegWit-BIP148

TRANSFER

Now you have to transfer the two folders CHAINSTATE and BLOCKS from your PC bitcoind directory to your raspberry.
I am using a program called "WINSCP" - it is free and easy to use: https://winscp.net/eng/download.php
We need this to transfer the files to the Raspberry pi. Pretty sure you can also do it via SSH - but I am the noob. So let's keep it simple.
Open Winscp and put in the IP Address of your Raspberry Pi, User and Password (same as in SSH)
You should now see the directories on your Raspberry Pi. There is a folder called
.bitcoin
enter it and you will see the two folders
blocks & chainstate
you can delete them on the raspberry as they have some data from your previous test inside.
Make sure you can also see the bitcoin.conf file in that directory, which needs to contain the exact same prune line, like the one on your desktop machine. If not, make sure to edit it via SSH. The line "datadir=l:\yourfolder" is obviously not needed in the Raspberry bitcoin.conf file.
Now grab the two folders CHAINSTATE and BLOCKS from your PC and copy them to your .bitcoind folder.
I also copied banlist.dat, fee_estimation.dat, mempool.dat and peers.dat to the folder - not really knowing if needed! Not needed.
The whole copy process might take some minutes (against some weeks in the old way).
After copying is finished, you can now start bitcoind on the Raspberry.
bitcoind &
the & symbol let you still use the command line while the process is running btw.
The process - if succesfull - will take some time to finish.
bitcoin-cli getinfo
Will give you some informations what is going on right now. When you can see, that it is checking the blocks, this is good!
If you get an error - double check - if you have the correct prune size (same as on desktop machine) - in bitcoin.conf and that this file is inside .bitcoin on RaspberryPi. It took me some time, to find my mistakes.
Congrats! You are almost a part of the network!
To make your node now a fullnode, you will need to go to your router (often 192.168.1.1) and enable portforwarding for your raspberry pi - and open ports 8333 - that's it!
You can now go to: https://bitnodes.21.co/nodes/
scroll down to "JOIN THE NETWORK" and check check if your node IP is connected!
It will show up as soon as the blocks are checked and the raspi is running.
Well done!
Now you are running a full node, with a small Blockchain and got it working in Minutes, not weeks!
I really hope, my little tutorial worked for you and your are part of the Node network now.
If you have problems or I made a mistake in this helper tut, just let me know and I will try to make it better.
Have fun and NODL!
the noob
tl;dr; (if you are a real noob start with the non-tl;dr version!)
tl;dr; PART ONE
1) Download & install / setup bitcoincore @ https://bitcoin.org/de/download
2) change dbcache to something smaller than your memory and download the whole Blockchain (120GB).
3) create a file called bitcoin.conf put the line prune=550 (or higher) in to activate pruning on win inside %appData%/bitcoin
4) Open ports 8333 on your Router to make this a full node with a smaller Blockchain.
You are running a full node on your PC.
tl;dr; PART TWO
1) Install jessie lite and the needed dependencies on your SDCard - Raspberry
( >git clone -b 0.14 https://github.com/bitcoin/bitcoin.git )
  • see tutorial for more info.
2) create a file called bitcoin.conf inside .bitcoin and add the same prune=Number you had on your PC.
3) transfer the pruned folders BLOCKS and CHAINSTATE to the Raspberry Folder .bitcoin
4)Start "bitcoind &"
5) let everything sync
6) Make sure you have port 8333 opened on your router.
You are running a full node on your Raspberry with a super small Blockchain (I put all on a 8GB SDcard)

September 21st Terracoin Update - Mandatory!!

MANDATORY UPGRADE OF THE TERRACOIN WALLET!
There is a mandatory upgrade of the Terracoin wallet in preparation for the hard fork on block 1087500 which will enable masternodes and decentralized governance.
Everyone must upgrade their wallet by block 1087500, which with current block timing is falling between the 29th and the 30th of this month!
We really need to get the word out to as many people as possible. So please post and talk to everyone you know.
This is a mandatory update which means if you continue to use the old wallet you will be on the wrong block chain and you won't be able to send or receive TRC from that wallet.
We also need to make sure that all of the mining pools (or whoever is throwing that crazy hash at TRC) have updated their wallets, otherwise the coins they mine will be worthless.
Always back up your wallet.dat file! Always back up your wallet.dat file!
Download the new wallets here: https://github.com/terracoin/terracoin
We will be using this repository going forward, but the old one has been updated as well.
The first time you run the binaries (or exes) it will create a new terracoincore folder. You can manually make it use your old terracoin app folder, but I recommend using the new folder. Stop (or close) the binaries and copy all of your files, except the peers.dat file over from the old folder into the new folder. That way you have an exact duplicate of your old data. (Except the peers.dat file, you will find .12.1.5 nodes faster without it, and you won't fully sync till you connect to a .12.1.5 masternode.)
Restart new binaries/exes.
It will say that it needs to reindex, so let it. Once it is done reindexing just sit back and wait for it to find .12.1.5 peers and masternodes. If it gives you an error saying network sync has failed, don't worry you just haven't gotten a .12.1.5 masternode yet. It will try again later.
If you are not sure how to do this please ask on one of the many forums. It is better to be safe then sorry!
I will be posting close to daily updates on which exchanges have updated their wallets and which haven't. If you see an exchange put the Terracoin wallet in maintenance that probably means they are upgrading it!
Hopefully we will have a Mac wallet out middle of next week.
In other news, the whale is now almost done with only ≈231,000 TRC left. He won't be around much longer. If you can get your TRC cheaper somewhere else then please do, but he has been consistantly selling to buy orders at .00003001 on Cryptopia. Once he is gone the price will most likely rise, so get it while you can!
Oh yeah, if you want you can set up your masternodes now, though you won't get rewards until the hard fork.
Numbers
30 days ago we were at 0.00001935 BTC (.0771 USD) and today we are at 0.00003010 BTC (.1098 USD).
A year ago we were at 0.00000442 BTC (.0026 USD).
We are ranked 321 on coinmarketcap with a market cap of $2,341,404 USD. Last week our market cap was $2,157,630 USD.

Lore v2 QT on Raspberry Pi

Hello,
 
To follow up to mindphuk's excellent piece on building the headless client on Raspberry Pi (https://www.reddit.com/blackcoin/comments/6gkjrw/wip_blackpi_a_stake_device_based_on_raspberry/), I thought if anyone was interested I'd show you how to get the full QT version running on the Pi on the Jessie with Pixel desktop. This works and has been soak tested for several days now on a standard Raspberry Pi 3. I have since added some coins and it stakes a handful of times a day.
 
Running staking Lore clients paves the way for some of the future use cases of BLK utilising the Bitcoin 0.12 (and newer) core tech, including colored coins. So I'm going to leave this one going indefinitely to kickstart the number of Lore clients staking. It's certainly not mandatory but it will be good in the longer term to have a nice distribution of Lore staking clients.
 
The cross-compile which lets you create binaries for multiple platforms didn't work for the QT version on the Pi, so there is more to do than just running the binary unfortunately, as below. There are folks working on some much cleaner solutions than this for the Pi, with a custom front end, and where you won't have to do any mucking about. That is coming soon. In the meantime, if you enjoy a fiddle with such things, here's how to get this QT client working on your Pi.
 
These instructions assume you are starting from scratch with a completely blank OS.
 
Download Jessie with Pixel from: http://downloads.raspberrypi.org/raspbian/images/raspbian-2017-07-05/2017-07-05-raspbian-jessie.zip
 
Note they have since (August 2017) released a version called 'Stretch' which does not work with this guide. I'll see if I can come up with something new for that at some point and link to it here when I have. In the meantime the guide should work with the Jessie image above.
 
Unzip the file and extract the .img file to burn it onto Fresh SD card to boot from (to be safe, use 16GB or larger), using a tool like win32diskimager or Etcher.
 
Assuming you have keyboard/mouse and monitor plugged into your pi, boot it up and the Jessie Desktop will show.
 
Before we do anything else, you should increase the default swap size on the pi, as compiling certain libraries can exhaust the RAM and get stuck otherwise. To do this, launch a Terminal window and type:
 
sudo nano /etc/dphys-swapfile 
 
and Change the CONF_SWAPSIZE from 100 to:
 
CONF_SWAPSIZE=1024 
 
Exit nano with control + x to write out the file.
 
Then, run the following to restart the swapfile manager:
 
sudo /etc/init.d/dphys-swapfile stop sudo /etc/init.d/dphys-swapfile start 
 
Now, launch the browser and download the Lore 2.12 binaries for ARM here: https://mega.nz/#!k2InxZhb!iaLhUPreA7LZqZ-Az-0StRBUshSJ82XjldPsvhGBBH4 (Version with fee fix from 6 September 2017)
 
(If you prefer to compile it yourself instead, it is possible by following the instructions in the original article by Mindphuk just taking into account this is the newer version of the Lore client than when that was written (https://github.com/janko33bd/bitcoin/releases) and the versions of Boost and the Berkeley DB need to be the same as below.)
 
Double click the zip and extract the Lore binary files. Yes, at the moment they are all called 'bitcoin', not 'blackcoin' or 'Lore' - this is because the code derives from a recent bitcoin core implementation so this has not yet been updated. You can place these wherever you like.
 
In the Terminal window, change directory to where you put the binaries, e.g.:
 
cd Downloads/lore-raspberrypi-armv7-jessie-pixel chmod +x * 
 
That marks the binaries as executable.
 
Now, we need the Boost libraries installed for any of the Lore binaries to work. The project was done with Boost 1.62.0. Unfortunately the Jessie repository only goes up to 1.55, so we need to download and build 1.62 manually on the device.
wget https://sourceforge.net/projects/boost/files/boost/1.62.0/boost_1_62_0.tar.gz/download tar -xvzf download cd boost_1_62_0 sudo ./bootstrap.sh sudo ./b2 install 
 
(This will take almost 2 hours. Have a nice cup of tea and a sit down.)
 
When I came to run the binaries, I found they couldn't find Boost. Running this command fixes that:
sudo ldconfig 
 
Now we are going to install the packages which aren't already included in the default OS installation which the binaries need in order to run:
sudo apt-get install qrencode libprotobuf-dev libevent-pthreads-2.0-5 
 
Now we need to install the Berkeley Database version 6.2.23. This is the version Lore v2 uses. Bitcoin still uses 4.8 which is 10 years old! This doesn't take too long.
wget http://download.oracle.com/berkeley-db/db-6.2.23.tar.gz tar -xvzf db-6.2.23.tar.gz cd db-6.2.23/build_unix ../dist/configure --prefix=/usr --enable-compat185 --enable-dbm --disable-static --enable-cxx 
 
I find this next section of the Berkeley instructions worked better just switching to root, which can be fudged by running sudo su before the rest:
sudo su make make docdir=/usshare/doc/db-6.2.23 install chown -v -R root:root /usbin/db_* /usinclude/db{,_185,_cxx}.h /uslib/libdb*.{so,la} /usshare/doc/db-6.2.23 
 
Now we're going to go up a couple of directories to where the binaries were:
cd ../.. 
 
Then run the client!
./bitcoin-qt 
 
And there you have it. Should hopefully end up looking a bit like this: http://imgur.com/a/eEHGa
 
Using the Bootstrap can save a while syncing. Download it at: https://www.reddit.com/blackcoin/comments/6b3imq/blackcoin_bootstrapdat_up_to_block_1631800
 
Place the bootstrap.dat file into the ~/.lore directory.
 
Run ./bitcoin-qt again, it will say 'Importing Blocks' rather than 'Synchronising with Network'. My pi sync'ed fully in about 5-6 hours.
 
If you want peace of mind that Lore will always start on bootup into the Jessie w/Pixel desktop (i.e. after a power cycle), then you need to create a .desktop file in the following place.
sudo nano ~/.config/autostart/Lore.desktop 
 
And in it, enter the following (tailoring the Exec line below to the whereabouts of your bitcoin-qt file):
[Desktop Entry] Name=Blackcoin Lore Comment=Mining without the waste Exec=/home/pi/Downloads/lore-raspberrypi-armv7-jessie-pixel/bitcoin-qt Type=Application Encoding=UTF-8 Terminal=false Categories=None; 
 
Power usage and payback time
 
After a good while leaving it going by itself, the CPU load averages got down to almost zero, all of the time. Idling, the Pi uses a bit less than 3 watts. This means it would take two weeks to use one 1Kw/h of electricity.
 
If you pay e.g. 12.5 cents a unit, that's what you'd expect this to cost to run in a fortnight. That's around $0.25 a month or $3 a year. Green and cheap and helping to secure the BLK network. I paid for the year's worth of electricity in 2 days staking with 25k BLK. Makes mining look silly, huh? ;)
 
Securing your Pi
 
With staking, your wallet needs to be unlocked and as such, the keys to your wallet are on the device. In a clean and newly installed environment as described above, and if you don't allow others to use your device and there is no other software or nasties running on it, there is no real cause for concern. However, there are some basic security precautions you can take.
 
Firstly, if you have enabled SSH and are playing with your pi across your LAN (or worse, the Internet), you should immediately change the password for the default 'pi' user (which is preconfigured to be 'raspberry'). Simply log in as normal, then type:
 
passwd 
 
You'll be prompted to enter the old and the new passwords.
 
Security by default
 
Your Pi is likely, by default, to not be exposed to incoming connections from the outside world because your router is likely generating a private address range for your LAN (192.168.x.x or 10.0.x.x or 172.x.x.x) which means all incoming connections are effectively blocked at the router anyway unless you set up a 'port forward' record to allow packets arriving on certain ports to be forwarded to a specific internal IP address.
 
As for accessing your Pi across the internet, if you have set up a port forward, this likely has security ramifications. Even basic old fashioned protocols have proven in recent times to have uncaught flaws, so it's always advisable to lock down your device as much as possible, and even if you only plan to access the Pi over your LAN, install a firewall to configure this. I used one called ufw, because it's literally an uncomplicated firewall.
 
sudo apt-get install ufw sudo ufw allow from 192.168.0.0/16 to any port 22 sudo ufw --force enable 
 
This allows just port 22 (SSH) to be open on the Pi to any device on my LAN's subnet (192.168.0.x). You can change the above to a single IP address if paranoid, or add several lines, if you want to lock it down to your LAN and a specific external static IP address (e.g. a VPN service you use). To find out what subnet your router uses, just type:
 
ifconfig 
 
and you'll see on the interface you are using (either hard wired or wifi) the 192.168 or 10. or 172. prefix. Change the above rule so it matches the first two octets correctly (e.g. 10.0.0.0/16 if you're on a 10.0. address).
 
You may already use VNC to access your Pi's desktop across your LAN, this uses port 5900. Add a line like above to lock it down to an internal address. It's not a good idea to expose this port to the wider world because those connections are not encrypted and potentially could be subjected to a MITM attack.
 
You can query the status of the firewall like this:
ufw status 
 
And of course, try connecting remotely once you change the rules to see what works. You should consult the official documentation for further options: https://help.ubuntu.com/community/UFW
 
Back up & Recovery
 
There are again many ways to tackle this so I'll just speak about my basic precautions in this regard. Don't take it as a be-all-and-end-all!
 
The wallet.dat file is the key file (literally) containing all the private/public keys and transactions. This can be found in:
 
~/.lore 
 
You can navigate there using Jessie w/Pixel's own file manager or in a terminal window (cd ~/.lore). You can copy this file or, if you'd rather keep a plain text file of all your public and private keys, use the 'dumpwallet' command in the console. In Lore, go to Help > Debug Window > Console and type 'dumpwallet myfilename' where myfilename is the file you want it to spit out with all your keys in it. This file will end up in the same place you launch bitcoin-qt from.
 
The instructions earlier on, when running Lore for the first time intentionally left out encrypting your wallet.dat file because in order for the wallet to stake upon startup, it needs to have a decrypted key already. This isn't perfect, but after a power cycle, it would never stake unless you left it decrypted. So the best practice here is as soon as the wallet.dat file has left your device, i.e. you copy it to a USB stick for example, put it in an encrypted folder or drive (or both).
 
In Windows, one way is to use Bitlocker drive encryption for the entire drive. You should follow the instructions here to encrypt your flash drive before your wallet.dat is on there, and don't forget the password!!
http://infosec.nmsu.edu/instructions-guides/how-to-enable-bitlocker-to-go-for-external-hard-drives-and-usb-flash-drives/
 
On the Mac, I use a software package called Concealer to encrypt files I store on the Mac itself: http://www.belightsoft.com/products/conceale   There are almost certainly free packages with similar functionality, I have just used that one for years.
 
Either way, if you want to just make sure your USB drive is encrypted, you can do so in one-click in Finder before you put the sensitive files on it: http://lifehacker.com/encrypt-a-usb-stick-in-finder-with-a-click-1594798016
 
Note that these disk encryption methods may mean having to access the USB stick on a PC or Mac in order to retrieve the files in the event of a disaster. Be aware this may mean exposing them to more security issues if your computer is in any way compromised or someone nefarious has access to your computer. There are more 'manual' ways of backing up and recovering, such as literally writing down private/public key pairs which this guide doesn't go into, but may suit you better if paranoid about your setup.
 
Recovery
 
The wallet.dat file has everything in it you need to recover your wallet, or if you used 'dumpwallet', the file you saved out has all the keys.
 
Wallet.dat method: Install Lore as normal then replace any auto-generated wallet.dat in ~/.lore directory with your backup. If a lot of time has elapsed and many transactions have occurred since your backup, launch lore with:
./bitcoin-qt -rescan 
 
And if that doesn't do the job, do a full reindex of the blockchain:
 
./bitcoin-qt -reindex 
 
If you used the dumpwallet command, install Lore then place the file containing all the keys that you saved out in the same directory as bitcoin-qt. In Lore, go to Help > Debug Window > Console and type 'importwallet myfilename' where myfilename is that file containing all the keys. The wallet should automatically rescan for transactions at that point and you should be good to go.
 
There are a million ways to do effective security and disaster recovery, but I hope this shows you a couple of basic precautionary ways. There are discussions about better ways to stake without compromising too much security which are happening all the time and developments in this regard will happen in time.
 
In the meantime, feel free to comment with your best practices.

(AUS) How to move wallet.dat file safely to a new wallet

My question is regarding the moving or importing of the wallet.dat file from a Macbook laptop that barely functions (it's very old) and Bitcoin QT wallet that doesn't open anymore (keeps crashing) to a new Mac computer and new wallet - Electrum. Just to explain it a bit better - I bought some coins back in 2013 and didn't touch them until I went to check up on them a few weeks ago. Weeks ago I could open the Bitcoin QT and saw that my bitcoins didn't sync up as they were 'Unconfirmed', but didn't understand much about how to get the private key etc.. Now that I have read up on that, I was going to open the Bitcoin QT and get the key, but this time the software crashed and wouldn't open again. So then I found the actual folder where the wallet.dat file is kept and copied it over to a USB stick. On my Mac computer I have downloaded the Electrum wallet (with seed), but I'm kind of stuck as what to do next. How do I move it safely? I have read many forums and it looks as though I just copy over this file into the Electrum folder and when I run the Electrum, the coins (even if they're unconfirmed) should show up. However, being super cautious - I'm still unsure how to do it securely. The wallet.dat is non-encrypted. Is it ok to copy this file over to the Electrum folder while I'm online? I have tried it while switching off the internet, but obviously I couldn't do anything as you need internet to run the software.. My main worry is - am I ok to copy this file onto my computer while I'm online? Should I encrypt it first? If yes, how? How would I encrypt it if my laptop barely functions? If I don't need to do it, is it just a simple matter of copying the file from my USB to Electrum data folder and bam, I should have my coins? Also, regarding the unconfirmed coins - they should still show up, right? And what do I need to do to confirm them? Many thanks for any answers.

Guide for first timers

I made this for my friends and family to use. Hope this heps someone. Much help!
bitcoins first: Get a wallet - just like physical money, you need a wallet to hold the money. use multibit - for a wallet - if you want options here a few http://bitcoin.org/en/choose-your-wallet go here and download this https://multibit.org/ how to backup your wallet https://multibit.org/help_backupWalletUsingPrivateKeys.html i recommend backing it up to at least 3 separate locations. example: harddrive, usb drive, encrypted dropbox folder.
go here to buy bitcoin also known as an exchange https://coinbase.com/?r=52dee75a8a2eed3e480000e5&utm_campaign=user-referral&src=referral-link
don't create wallet, click sign up button on top right. add bank information, and credit card info, and phone info - phone allows 2 factor authentication so your identity becomes much more difficult to fake and steal your money and information. I asked them to send me a SMS message instead of using app. this is the most reputable place to do this at. Never never use an online wallet!!!
buy some bitcoin on coinbase.com, and send yourself some bitcoin using your multibit wallet address(under the Request tab it shows your address there)
Now Dogecoin First get a wallet, - use the qt wallet. You can get it here for either Mac or Windows. http://dogecoin.com/ for linux use this guide - http://www.reddit.com/dogecoin/comments/1tvmnd/dogecoin_on_linux_the_complete_beginners_guide/
For a place to buy dogecoin. Use cryptsy, here is the link. https://www.cryptsy.com/users/register?refid=138894
click register new account. enter your information. go to your settings, and enable 2 factor authentication, use your cell phone number, and put in the number that they send to your phone. This makes it much more secure. you will send your bitcoins here and then buy dogecoin, then send the dogecoin to your wallet on your own computer. Backup the wallet after every purchase.
Send your Dogecoin to your own wallet. backup your wallet, at least 3 times. Use USB thumb drives. FYI, This might take away, the withdraw servers are slow as of right now. Took 3 days for me.
If you have any questions ask. Also you can buy Dogecoin or Bitcoin on ebay, do that at your own risk.

How to upgrade to Bitcoin Core v0.11.0 on ubuntu 14.04?

I'm a total linux noob and need help upgrading. I'm running v10.2 which I installed using the ppa. I don't think the ppa is updated yet so I downloaded 0.11.0 from bitcoin.org/en/release/v0.11.0. According to that site to upgrade you "copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux)." The only folder I can find is /usshare/doc/bitcoind and I don't think that's it. What do I do once I find the folder? Just extract the contents of the tar.gz there? Any help is much appreciated thank you.

The Absolute Crypto-Coine Beginenrs Guide to MyriadCoin-Mining

Hello, I'm a new member of the Myriadcoin-Community and I made a mining guide for crypto-currency newbies over on my blog. I thought it would fit here as well, hoping that some newbie would discover it upon his quest for mining crypto-coins. (I hope it is ok, that I just copied it over)

The Absolute Crypto-Coin Beginners Guide to MyriadCoin-Mining

Introduction

I researched the technology behind Bitcoin, especially the blockchain, for the past week because it could have been helpful with my current research on electronic voting that I am doing for my project thesis. During that I was amazed by the simple and yet powerful ideas behind crypto-currency. I was tempted to invest some of my spare money (which is not much as an undergraduate) into crypto-currencies, but was appalled by the weak points of Bitcoin, that become apparent if one researches it. (Malleability, 51% Attacks, Selfish Mining, etc. If there is interest I can maybe try to scramble together an article going in detail about attacks on crypto-currencies)
Then I discovered Myriadcoin, which solved most of the problems I had with Bitcoin. Although I myself am quite new to the Myriadcoin-Community I present to you, the absolute crypto-coin beginners guide to Myriadcoin-Mining. The following guide is written for Windows, the process may be similar on Linux/Mac OS but is not 100% the same

Setting up your Wallet

Your Myriadcoin-wallet is very much like your everyday wallet. It holds your currency, and if you lose it your money is gone.
  1. Go to the Myriadcoin homepage
  2. Download The wallet for your OS. (Currently there are Windows and Mac OS Wallets)
  3. Unzip the downloaded
  4. Start the myriadcoin-qt.exe
After the installation is done you should see your wallet stating that your current funds are 0 MYR. At the beginning the wallet has to download all the information from the blockchain, which can take a while. You can see the progress at the bottom of the wallet. Upon pressing the receive-button at the top you will see your automatically generated address. This address can be used to receive Payment. You can generate as many adresses as you want. Under Settings you can Encrypt your wallet, which you probably should do if you plan to use it seriously. Keep in mind, that if you lose your password you have no means to get to your money. Under File you can create a backup and save it somewhere.

Getting to Mine

Mining is the process which verifies currency transactions between accounts. It is simultaneously the process which generates new coins up to a limit. (20 billion is the limit for MYR). To mine a block means to solve a cryptographic puzzle in form of a hash. Myriadcoin uses 5 of those hash-algorithms. If you are a complete newbie to mining and crypto-currencies chances are you do not have specialized Hardware. Because of that it probably is best if you mine using the skein, groestl or qubit algorithms. Do not be scared of the names, I will guide you trough. If you made your mind up which of those you want to use (just pick one, if you do not want to research them) you can go to this post. The following step by step guide is using the skein algorithm with the Modified cgminer and the cryptorus mining pool. The steps can differ slightly if you use a different algorithm or pool, but should be similar.
  1. Go to the above linked post and scroll down to the Standalone Miner Section
  2. Pick a miner. (I use the modified cgminer
  3. Got to the post again and scroll to the Pools Section
  4. Pick one of the mining Pools fitting your chosen algorithm. (I pick http://myrsk.cryptorus.com/ for this one)
  5. Go to the homepage and register if necessary (Lets say my name is Testhans)
  6. Once you registered you should look for the My Workers Option
  7. There create a new worker. (Lets say I make a worker with the name Myry and the password 1234)
  8. Now unzip the Miner you downloaded
  9. Go to the folder of the miner and create a new textfile that you name run.bat
  10. Go to your pool-website and look for the stratum address. (Can be usually found on the startpage, in this my case stratum+tcp://myrsk.cryptorus.com:3333)
The run.bat should look as follows:
name_of_miner.exe -o stratum-address -u YouName.Workername -p Workerpassword (For some algorithms you have to set the algorithm as an option too)
This is how my config looks with the examples above:
cgminer.exe --skein -o stratum+tcp://myrsk.cryptorus.com:3333 -u Testhans.Myry -p 1234
Save the run.bat and you should be able to start the miner through double clicking. A console-window should open displaying the progress. Every time you find a share a message saying something along the lines of "Accepted 214sabc5fe 4/2" should be displayed.
You can enter your Myriadcoin-address inside the Account-Options of your pool, so you can receive your share of the coins you mined. Typically you have to arrange the transaction yourself. Usually the miner can take a lot of options to optimize the amount it can mine, but as a newbie you are likely to break more than you get out of it. The standard-configuration of miner-tools is in most cases pretty good allready.

Further Resources

You can find further resources on the bitcointalk-forums and the awesome subreddit. Also there is another mining-guide, which goes into more detail on all of the algorithms and can be quite helpfull if you are just new to Myriadcoin and not to the crypto-currencies as such.
If you have any suggestions or questions feel free to leave a comment, and if you found my guide useful and want to share some of your hard-mined coins, you can do that also. My Myriadcoin address is MKF8EPYksAV4Bn7M8HLEMyvEPtq3EWeGVW

Bitcoin security best practice

What are the best practices someone should take to secure their bitcoins (& Litecoins)? I've recently downloaded Bitcoin-QT and Litecoin-QT and transferred my coins to my wallets. So far I've encrypted my wallet with a passphrase. I've read that I should do a paper wallet which I'm going to do but is there anything more I should be doing?
Thanks for any help and apologies if you've seen this message a hundred times before but I couldn't see anything that detailed a straight up best practice for securing your bitcoins.

How to move Bitcoin data directory on MAC OSX to external drive.

Assumptions: A) Your current folder for your bitcoin data is here: "~/Library/Application Support/Bitcoin" or here "/Users//Library/Application Support/Bitcoin" B) Your current folder for your bitcoin-qt application is here: /Applications/Bitcoin-qt.app C) You have an external drive named "My Passport" and your Finder, Preferences settings are set to display Devices. Select Finder, Preferences and tick the box to the left of External disks.
To do this on a MAC running OSX 10.9 follow these instructions: 1)Open Finder. 2) In Finder, using the Finder menu bar, select: Go, Go To Folder... , and type the ~/Library and press RETURN. 3) In Finder, navigate to the "Application Support" folder. You will see the Bitcoin directory. 4) In Finder, select, or highlight, this folder, then select: Edit, Copy "Bitcoin" from menu bar. 5) In Finder, navigate to your external drive "My Passport". 6) In Finder, create a folder called "Applications" on your "My Passport" external drive (see step "C" above after connecting external drive, if necessary). 7) In Finder, navigate to the newly created "Applications" directory. 8 ) In Finder, select Edit, Paste Item to start copying the "Bitcoin" directory to your external drive's "/Volumes/My Passport/Applications/" folder. 9) Once this completes and both the "~/Library/Application Support/Bitcoin" and "/Volumes/My Passport/Applications/Bitcoin" folders are identical. Rename the Bitcoin directory in "~/Library/Application Support/Bitcoin" to "~/Library/Application Support/BitcoinOLD". 10) Launch Terminal from LaunchPad, Utilities or from Applications in Finder. 11) CAREFUL: At the Terminal prompt type: "cd ~/Library/Application\ Support" no quotes. Yes, that "\" slash is necessary. 12) Type: "ls -laf" no quotes, and insure that the Bitcoin directory is now called BitcoinOLD. 13) Type: "ln -s /Volumes/My\ Passport/Applications/Bitcoin/ ./Bitcoin" no quotes. this command actually creates a symbolic link to your external drive. Yes, that slash "\" just after the "My" is necessary to account for the space in "My Passport". 14) Launch Bitcoin-qt from Applications in Finder and let the "Reindexing blocks on disk.." process complete. It should not be downloading anything until this completes and then will download only those blocks since your last synchronize to the Bitcoin network. 15) Once this completes, delete the BitcoinOLD folder using finder. "~/Library/Application Support/BitcoinOLD". Was this helpful? Donate: 1FCZzLuH1MAa8UDaHnZKHnXmNcQRBA7Xme

Unable to use any Invictus apps. Can someone help?

I posted my original question here: https://bitsharestalk.org/index.php?topic=2735.0 and followed the instructions here: https://bitsharestalk.org/index.php?topic=1936.0 but my ProtoShares-Qt-0.2.0 for Mac OS X app will not connect to any nodes. My firewall is off and I am able use other Qt clients just fine.
What app should I use to get a ProtoShares wallet that works? Is ProtoShares even a thing anymore or is it AngelShares now? Or BitShares? Or BitShares X? What's with this naming scheme? Who is doing the marketing for Invictus? I fix Macs for a living and I can hardly figure out how any of these products relate to each other.
In an attempt to see if I could get any Invictus app to work for me I have visited the Invictus site and GitHub but have been unable to find an installer or .dmg file for any Invictus app that "just works". Are there no Invictus apps that just function out-of-the-box after a simple download and drag and drop into the Applications folder on my Mac? Do all Invictus products require the user to compile the software themselves? If this is the case can a forum moderator or Invictus employee provide with a link to a working version of ANY Invictus app that will function on a Mac?
Perhaps it is just easier to just purchase some ProtoShares with Bitcoin on Cryptsy and forget trying to use any of Invictus' software. Of course that is problematic too because I still need to get my PTS off Cryptsy at some point. As I asked before, is ProtoShares even the right thing? Or should I buy BitShares?
Halp!

Bitcoin Core initial synchronization will take time and download a lot of data. You should make sure that you have enough bandwidth and storage for the full block chain size (over 350GB). If you have a good Internet connection, you can help strengthen the network by keeping your PC running with Bitcoin Core and port 8333 open. On the new Mac OS X you can't see the Bitcoin folder in the library under /application support/. You have to use Finder and in the menu look for GO and then GO TO type ~/Library in the box. After that you can see the Bitcoin folder under /application support/. If you have already downloaded the data then you will have to move the data to the new folder. If you want to store them in D:\BitcoinData then click on "Properties" of a shortcut to bitcoin-qt.exe and add -datadir=D:\BitcoinData at the end as an example: "C:\Program Files (x86)\Bitcoin\bitcoin-qt.exe" -datadir=d:\BitcoinData Mac OS X v10.7 (Lion) came out, and it has the ~/Library folder hidden, see the answer from chilled35 to access it with Finder. In order to see hidden folders, such as ~/Library from Finder, simply hit shift + ⌘ (command) + G which will GO to a folder, then paste in this location: ~/Library/Application Support/Bitcoin Download Bitcoin Core.
