This fork of vertcoind incorporates "watch only" addresses, allowing the import of public VTC addresses without also having the private key.

The primary practical use for this vertcoind fork is to facilitate zerotrust vertcoin web wallet projects like Vertpunk and community-based services like

What is Vertcoin?

Vertcoin is a lite version of Bitcoin using scrypt-adaptive-N as a proof-of-work algorithm.

  • 2.5 minute block targets
  • subsidy halves in 840k blocks (~4 years)
  • ~84 million total coins
  • 50 coins per block
  • Every block to retarget difficulty with Kimotos Gravity Well algorithm

For more information, as well as an immediately useable, binary version of the Vertcoin client sofware, 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 Vertcoin 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 mailing list.

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 Vertcoin.


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
make -f Makefile.test
