What is Cannacoin?

At block 370,000 Cannacoin will transition to its own Proof-of-Stake-Velocity (PoSV) algorithm which replaced Proof-of-Work (PoW).

Cannacoin first started in March 28th 2014 as a variant of Litecoin using Scrypt as the Proof-of-Work (PoW) hash algorithm.

  • 1 minute block target
  • 12.5 coins per block
  • Subsidy halves every 526,000 blocks
  • Difficulty retarget: Every block using Kimoto's gravity well

For more information, as well as an immediately useable, binary version of the Cannacoin wallet client, please visit http://www.cannacoin.cc.

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 Cannacoin 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 (if they haven't already) on the appropriate channels.

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/coding.txt) or are controversial.

The master 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 Cannacoin.


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

Automated Testing

Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code.

Unit tests for the core code are in src/test/. To compile and run them:

cd src; make -f makefile.unix test

Unit tests for the GUI code are in src/qt/test/. To compile and run them:

qmake BITCOIN_QT_TEST=1 -o Makefile.test bitcoin-qt.pro
make -f Makefile.test
