Connecting bitcoin-qt to bitcoind on local network
Hello, I have a bitcoin node running on a headless box (bitcoind) and I would like to connect to it using bitcoin-qt on my desktop. I'm getting a little confused with the process.... does bitcoin-qt need to connect to bitcoind using RPC? Do I store my wallet file on the bitcoind box, or bitcoin-qt box? The bitcoin node is already setup to work with an electrum server, so I already have rpcbind=0.0.0.0, rpcallowip=$ELECTRUX_IP, and rpcuserpcpassword set. I tried adding my desktop IP to rpcallowip, and setting the appropriate username/password in bitcoin-qt's bitcoin.conf, but no luck. I can see in debug.log for bitcoin-qt that the connection is rejected. The node runs over TOR and I have onlynet=onion set in bitcoind's bitcoin.conf, but that doesn't seem to stop electrumx connecting via RPC over clearnet, so this shouldn't be an issue right? Am I missing something here? Help would be much appreciated!
The Bitcoin-Qt client is known for taking a very long time to synchronize itself with the network. During the first hour, there's little indication of progress at all. During synchronization, it's impossible to send or receive bitcoin. All of this baffles new users who understandably conclude that something is wrong with their computer, the network, Bitcoin-Qt, Bitcoin itself, or all of the above. For this reason, new users are often directed toward alternatives such as Web wallets. The net effect is fewer full nodes and a trend toward centralization. One solution is Ultraprune. David Perry gives an introduction. In a nutshell, Ultraprune makes it possible to validate transactions using a fraction of the storage space. This is supposed to speed up synchronization. The GitHub commit history indicates that Ultrprune was merged into Bitcoin-Qt a year ago. However, 0.8.6-beta shows exactly the same old behavior - extremely long synchronization time during which not much is possible. Was Ultraprune ever released in Bitcoin-Qt? If not, why not? If so, how is it enabled?
I tried asking this in the bitcoincore sub yesterday, but it only has a handful of members and got no answers, so i now try here. When bitcoin-qt is first started, it asks for the location of datadir. If it is set to a custom location, it remembers it on subsequent launches. Where is this location stored, as no bitcoin.conf is generated in the default location, and i have not seen any other documentation to specify datadir except command line option and bitcoin.conf file?
I have set up a small rig, with a few usb miners that i managed to get for a cheap price, was reading about on forums and read about setting up your own node and mine on your own, in hope to mine a whole block. I have set up everything, switched on cgminer and passed on a few parameters... -o -u -p and --btc-address. Now my question is, for the --btc-address parameter, i need to insert my receiving bitcoin address ? can i use one from my hardware wallet or does it have to be one that the Bitcoin-QT (Bitcoin Core) that cgminer is attached to ?
Linux noob needs help getting a Bitcoin Classic node running on Lubuntu
I've installed Lubuntu 15.10 on an old laptop that used to be Windows XP. Seems to run fine. I tried Ubuntu but the laptop struggled to run it. I've downloaded bitcoin-0.11.2-linux32.tar.gz as my Lubuntu installation is 32 bit. I've extracted the contents but don't have a clue how to install - dont laugh, I've only ever used Windows before. The bitcoin-0.11.2 folder contains the following folders: Bin Include Lib I assume the file I want to run to install is in bin? The options are: Bitcoin-cli Bitcoind Bitcoin-qt Bitcoin-tx And two others starting 'test' Which of the above do I run to install Classic? And how do I run, is it a matter of simply double clicking, or do I use the Terminal? If so, what is the terminal command? Thanks for your help.
So I bought 0.05 BTC, not breaking the bank or anything, and transferred them to a wallet address given to me by Bitcoin-qt. Bitcoin-qt can't synchronise, as I don't have enough disk space for all the blocks. My question is, how do I get my BTC back? Is it gone forever? I know some people have had some issues with Blockchain but I just want to transfer my piddly small investment there so that my computer stops bugging me about low disk space! Just to clarify, bitcoin-qt thinks I have nothing in my wallet as it hasn't synced up to the point where I transferred in my purchase. Any and all help will be greatly appreciated.
I am completely naive when it comes to Linux, coding, compiling, etc., so I found it difficult to follow advice I found for compiling the bitcoin diamond code form git. I followed a few guides for bitcoin core first and could never get it to work. I got some help from someone that knows Linux and here's what finally worked for me with BCD. Use rufus to make bootable usb with ubuntu iso. (https://rufus.akeo.ie/) Boot from the usb and install ubuntu. Follow this guide to compile bitcoin from git: https://www.toshblocks.com/bitcoin/compile-bitcoin-source-code-ubuntu-16-04-lts/ Do the entire guide with bitcoin core to ensure everything is working. Make sure you replace "theusername" with your own each time it appears, or make "theusername" your user name from the beginning. There was one small difference, at the end of the guide to run bitcoin-qt it is ./src/qt/bitcoin-qt At the end when trying to run bitcoin-qt (./src/bitcoin-qt) it said there was no such file, which made me think that I did something wrong but you just have to find where the file is. Hey, I said I was a complete noob, go easy on me. When you repeat the procedure for BCD there will be a few small changes: git clone https://github.com/bitcoin/bitcoin.git becomes git clone https://github.com/eveybcd/BitcoinDiamond.git mkdir bitcoin/db4/ becomes mkdir BitcoinDiamond/db4/ ../dist/configure --enable-cxx --disable-shared --with-pic --prefix=/home/theusername/bitcoin/db4/ becomes ../dist/configure --enable-cxx --disable-shared --with-pic --prefix=/home/theusername/BitcoinDiamond/db4/ ./configure LDFLAGS="-L/home/theusername/bitcoin/db4/lib/" CPPFLAGS="-I/home/theusername/bitcoin/db4/include/" becomes ./configure LDFLAGS="-L/home/theusername/BitcoinDiamond/db4/lib/" CPPFLAGS="-I/home/theusername/BitcoinDiamond/db4/include/" when you get to this line: [email protected]:~/BitcoinDiamond$ ./autogen.sh I got the following error: bash: ./autogen.sh: Permission denied this command will show some information about autogen.sh [email protected]:~/BitcoinDiamond$ ls -l autogen.sh -rw-rw-r-- 1 mmmmm mmmmm 527 Dec 30 21:26 autogen.sh same command comparing it to the bitcoin core version of autogen.sh $ ls -l ../bitcoin/autogen.sh -rwxrwxr-x 1 mmmmm mmmmm 527 Dec 30 21:03 ../bitcoin/autogen.sh do this to make them the same [email protected]:~/BitcoinDiamond$ chmod a+x autogen.sh recheck autogen.sh and it should match the bitcoin core autogen.sh now [email protected]:~/BitcoinDiamond$ ls -l autogen.sh -rwxrwxr-x 1 mmmmm mmmmm 527 Dec 30 21:26 autogen.sh continue on [email protected]:~/BitcoinDiamond$ ./autogen.sh [email protected]:~/BitcoinDiamond$ ./configure LDFLAGS="-L/home/mmmmm/BitcoinDiamond/db4/lib/" CPPFLAGS="-I/home/mmmmm/BitcoinDiamond/db4/include/" [email protected]:~/BitcoinDiamond$ make -s -j5 It will work a while and then you'll get the following error, among others: /bin/bash: ../share/genbuild.sh: Permission denied It's the same error as with autogen.sh, so find it and fix it by the following: [email protected]:~/BitcoinDiamond$ find . -name genbuild.sh ./share/genbuild.sh [email protected]:~/BitcoinDiamond$ chmod a+x ./share/genbuild.sh continue on by restarting make [email protected]:~/BitcoinDiamond$ make -s -j5 It should be good! go to and run bitcoin-qt to start the gui [email protected]:~/BitcoinDiamond/src$ cd qt [email protected]:~/BitcoinDiamond/src/qt$ ./bitcoin-qt bitcoin-wt will spend some hours syncing the entire blockchain so you have to wait. When it is finished, import private keys by: clicking in the "Bitcoin Core - Wallet" window to make it active hover mouse in top left of the grey bar on the top of the deskto screen, not the "Bitcoin Core - Wallet" until it says "file settings help" click on "help" click on "Debug Window" click on the "Console" tab enter "importprivkey 5KJvsngHeMpm884wtkJNzQGaCErckhHJBGFsvd3VyK5qMZXj3hS" with your own key make an account at gate.io where they are allowing deposits sell!, or don't, maybe you're nuts, who am I to judge
Where does the Bitcoin-QT options dialog store options
When running Bitcoin-QT, there is an options dialog you can get to in the GUI under Settings. I've played with some of these settings and they don't store where I would expect. I've run some tests, on Windows 10, and it they are not housed in the bitcoin.conf file. What's more the settings persist if you change named conf files. Is it housed in the registry or some other file on the filesystem?
Hello, is it possible to import/send my Bitcoin from my old computer to a new one with a new wallet without using the classic send option? Can i Import it with the private key of the old wallet? Will it be safe that way? Will the new wallet be safe? Best regards.
for basic format validation edit1: i understand there's a lot more to checking the address. i want a regex for syntax only at this point. edit2: also a uri question
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 Start Bitcoin, now you will see all the files are created in the new data directory.
