Fedora Personal tools Log in Views Page Discussion History BITCOIN From FedoraProject Jump to: navigation, search Contents 1 2 3 4 /show_bug.cgi?id=1020292 Bitcoin is used in two different ways.The most common is as a user daemon (bitcoind) or graphical UI (bitcoin-qt) that both use ~/.bitcoin/ in the user homedir.Less common is as a system service with homedir in a location like /var/lib/bitcoin.The package should support either modes of operation, but for the sake of simplicity they should share the same SELinux contexts, fs labels and policy.User service bitcoind and graphical bitcoin-qt The most common way to use Bitcoin Core is users run their own bitcoind or bitcoin-qt as a non-root user with datadir ~/.bitcoin/.Note: Arbitrary other services may need to be granted both UNIX filesystem and SELinux permission to read the autotoken file from the user's ~/.bitcoin directory.This is a newer way in which bitcoin-cli is intended to know how authenticate with the bitcoind RPC interface that in Warren's opinion is difficult to support in a consistent way.

Perhaps for now we should suggest using the old method of manually configured rpc ports, usernames and passwords.Maybe we provide an example user-level systemd .service file.System Service bitcoind bitcoind is not normally used as a system service but people want it to be packaged in this way.Perhaps this should be an optional sub-package like bitcoin-system-service.It would contain only the .service file, config, and README's.Should have its datadir somewhere like %{_datadir}bitcoin/ which expands to /var/lib/bitcoin/ Config file %config(noreplace) %{_datadir}/bitcoin/bitcoin.conf with wallet disabled by default, but they could enable it with wallet=1 if they really want it.With system username like: bitcoin %doc README-FEDORA-BITCOIN-SERVICE should probably explain how the service is meant to be configured, used and controlled with bitcoin-cli or RPC/REST interfaces as the non-default datadir does not match upstream documentation and it thus may be non-obvious to users.

The system is peer-to-peer and transactions take place between users directly.One of the important pieces of software required when using Bitcoins is a Bitcoin Wallet.On Fedora, there is a new Bitcoin wallet called Electrum that you can use to send and receive Bitcoins.Installing Electrum Electrum is fast, secure and easy to use, and you can install it via GNOME Software or dnf on Fedora 25: Create your first wallet with Electrum After you have installed Electrum, start the Application, and you will be greeted by a startup wizard, stepping you through the basic setup.xbox one bitcoin minerIn this example, follow the steps in the screenshots below to create a Standard Electrum Bitcoin wallet.bitcoin profit taxableBe sure to write down the generation seed with a pen on a paper, do not store it on your computer.bitcoin anlık değer

Do it now, before you receive any Bitcoins!Receiving Bitcoins You can buy bitcoins with national currencies from a private seller or through an exchange.When buying or receiving bitcoins, you will need to provide the other person/system with your Bitcoin address, which is in the Receive tab in the main Electrum window Sending Bitcoin You can also send bitcoins, which is done via the Send tab in electrum.When sending Bitcoins, you will need the receiver’s Bitcoin address, which can be text, a Bitcoin url or QR-image.request bitcoin donationYou might want to adjust the fee depending on the priority of the transaction, I selected the lowest fee since transfer time was not important.ethereum advantagesWe are happy to hear your experiences with Bitcoin on Fedora.Did you experience any difficulties?What wallet(s) do you use?Anything else regarding Electrum or Bitcoin?

Or, you can just skip all the work and use my existing Yum repository.This also gives you standards-compliant paths, as well as an SELinux-enabled bitcoind.Read the RPM spec files if you're really interested in the build process.up vote 3 down vote This is how I compiled bitcoind from the github source on Fedora 18. sudo yum install gcc-c++ make sudo yum install boost-devel sudo yum install db4-devel sudo yum install openssl-devel sudo yum install rpm-build sudo yum install lynx sudo yum install python-devel sudo yum install miniupnpc sudo yum install miniupnpc-devel.i686 sudo yum install libdb-cxx.i686 sudo yum install libdb-cxx-devel.i686 /source/ save and untar it in a directory, let's say ~/installs/openssl_ecdsa cd ~/installs/openssl_ecdsa ./config make sudo make install now pull the latest bitcoin source from github cd ~ /bitcoin/bitcoin.git if you want the latest stable release, /en/download git checkout 0.8.3 //latest stable at the moment cd bitcoin/src export OPENSSL_INCLUDE_PATH="/usr/local/ssl/include" export OPENSSL_LIB_PATH="/usr/local/ssl/lib" make -f makefile.unix up vote 0 down vote You'll need to install these libraries: libssl - provided by openssl in Fedora libboost - called boost in Fedora libdb4.8 - called db4.8 in Fedora miniupnpc I'm not able to test this at the moment, but try something like this: yum install openssl boost db4.8 miniupnpc Once those are installed, and their src or dev packages may be necessary, you can do the actual build itself: cd src/ make -f makefile.unix Also requires openssl-devel up vote 0 down vote Tested on Fedora 20, 64-bit: $ sudo yum groupinstall -y "Development Tools" "Development Libraries" $ sudo yum install -y gcc-c++ libtool swig pyqt4-devel python-psutil python-twisted wget protobuf-devel $ /berkeley-db/db-4.8.30.NC.tar.gz' | tar -xzv && cd db*/build_unix $ ../dist/configure --enable-cxx --disable-shared --with-pic --prefix=/usr/local/ $ make $ sudo make install $ /source/openssl-1.0.1i.tar.gz | tar -xzv && cd o* $ export CFLAGS="-fPIC"; ./config --prefix=/usr/local shared enable-ec enable-ecdh enable-ecdsa $ make depend && make all $ sudo make install $ /bitcoin/bitcoin.git; cd bitcoin $ ./autogen.sh && ./configure LDFLAGS="-Wl,-rpath=/usr/local/lib64 -L/usr/local/lib/ -L/usr/local/lib64/" CPPFLAGS="-I/usr/local/include/" $ make $ sudo make install $ /averageradical/compile/gh-pages/example/bitcoin.conf $ bitcoin-qt # or nohup bitcoind & $ bitcoin-cli help Your Answer Sign up or log in Sign up using Google Sign up using Email and Password Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.
