The IoP Blockchain client version 6.2.3 is now available


Fixed bug that causes nodes to crash if a new block contains duplicate inputs (recently discovered in bitcoin core, compare http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-17144)
Fixed segregation fault on running iop-qt with startup arguments that cause the program to exit before the Qt backend is initialized.


Input field in the "Buy IOP" dialog will now change color if input is out of range instead of rejecting input.

Known Issues

Toolbar icons still render imperfectly
Scaling on Linux and Windows is still broken. To work around it, start the program with QT_SCALE_FACTOR=2 iop-qt or equivalently.
We received feedback about some possible UI improvements. Stay tuned!

The correct version for your OS

If you are using Windows, you should most probably download the iop-core-6.2.2-win64-setup-unsigned.exe. If you are using a somewhat older computer, you might need to use iop-core-6.2.2-win32-setup-unsigned.exe file. To find out if your computer is capable of running 64-bit software, right-click on the Windows icon on the left of the taskbar and click on "System"|. A new window will open and you will find the Information under "System Type". After you downloaded the appropriate file, run it to install the IoP Core wallet.

macOS users should download iop-core-6.2.2-osx-unsigned.dmg. To install, mount the image file by double-clicking. A new window will open and you can drag the application onto your Applications folder.

Ubuntu users can use the iop-core_6.2.2-ubuntuXXXX_amd64.deb file, appropriately named for your version of Ubuntu. To install, open a terminal in the folder containing the downloaded file and run dpkg -i iop-core_6.2.2-ubuntuXXXX_amd64.deb. If you have problems starting the program afterwards, please run sudo apt-get install -f.

If you are on another version of Linux or a 32-bit system, please download the static binaries contained in iop-core-6.2.2-i686-pc-linux-gnu.tar.gz. Extract the archive to a location of your choice and possibly add it to your PATH variable.

Power Users might also want to download the relevant archive file for their operating system, which contain the command-line version of the IoP software. The rest of the .tar.gz files are intended for uncommon architectures and are untested, feedback is appreciated.

Naming Scheme

The binaries are iopd, iop-cli, iop-tx and iop-qt, while the Windows and macOS executables are iop-qt.exe and IoP-Qt.app, respectively. The configuration file is called iop.conf.

The default data directory for both the command line and the Qt Wallet is

  • ~/.iop on Linux,
  • %APPDATA%\IoP on Windows, and
  • ~/Library/Application Support/IoP on macOS.

The Qt Wallet (NOT the command line utilities) will pick up your previously used data directory.
