What is BeaverCoin?

BeaverCoin is a cryptocurrency basend on Bitcoin and BeaverCoin, using scrypt as a proof-of-work algorithm.

  • 1 minute block targets
  • 8 coins per block
  • subsidy halves in 210k blocks
  • ~3.36 million total coins
  • 1440 blocks to retarget difficulty

For more information, as well as an immediately useable, binary version of the BeaverCoin client sofware, see


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

Development process

Developers work in their own trees, then submit pull requests when they think their feature or bug fix is ready.

If it is a simple/trivial/non-controversial change, then one of the BeaverCoin development team members simply pulls it.

If it is a more complicated or potentially controversial change, then the patch submitter will be asked to start a discussion with the devs and community.

The patch will be accepted if there is broad consensus that it is a good thing. Developers should expect to rework and resubmit patches if the code doesn't match the project's coding conventions (see doc/ or are controversial.

The master-0.10 branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are created regularly to indicate new official, stable release versions of BeaverCoin.


Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.

Manual Quality Assurance (QA) Testing

Large changes should have a test plan, and should be tested by somebody other than the developer who wrote the code. Creating a thread in the BeaverCoin discussion forum will allow the BeaverCoin development team members to review your proposal and to provide assistance with creating a test plan.


Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.

We only accept translation fixes that are submitted through Bitcoin Core's Transifex page. Translations are converted to BeaverCoin periodically.

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 beavercoins" 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.


BeaverCoin 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.
