SmartCoin 1.1 (August 2020)


What is Smartcoin?

Smartcoin is a cryptocurrency like Bitcoin, using X11 as its proof of work (POW) algorithm. Dogecoin Core 1.14.2 code has been used as a base for the most recent Smartcoin update for much wow performance and stability.


Smartcoin is released under the terms of the MIT license. See COPYING for more information or see

Development and contributions

Development is ongoing, and the development team, as well as other volunteers, can freely work in their own trees and submit pull requests when features or bug fixes are ready.


Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code. Unit tests can be compiled and run (assuming they weren't disabled in configure) with: make check. Further details on running and extending unit tests can be found in /src/test/

There are also regression and integration tests of the RPC interface, written in Python, that are run automatically on the build server. These tests can be run (if the test dependencies are installed) with: qa/pull-tester/

Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.

Development tips and tricks

compiling for debugging

Run configure with the --enable-debug option, then make. Or run configure with CXXFLAGS="-g -ggdb -O0" or whatever debug flags you need.


If the code is behaving strangely, take a look in the debug.log file in the data directory; error and debugging messages are written there.

The -debug=... command-line option controls debugging; running with just -debug will turn on all categories (and give you a very large debug.log file).

The Qt code routes qDebug() output to debug.log under category "qt": run with -debug=qt to see it.

testnet and regtest modes

Run with the -testnet option to run with "play smartcoins" on the test network, if you are testing multi-machine code that needs to operate across the internet.

If you are testing something that can run on one machine, run with the -regtest option. In regression test mode, blocks can be created on-demand; see qa/rpc-tests/ for tests that run in -regtest mode.


Smartcoin Core is a multithreaded application, and deadlocks or other multithreading bugs can be very difficult to track down. Compiling with -DDEBUG_LOCKORDER (configure CXXFLAGS="-DDEBUG_LOCKORDER -g") inserts run-time checks to keep track of which locks are held, and adds warnings to the debug.log file if inconsistencies are detected.
