What is Datacoin?

Datacoin is intended to be reliable censorship-free data storage and a currency to pay for this storage.

Datacoin is based on Bitcoin-style blockchain and Primecoin proof-of-work.

This repository a high-performance version of Datacoin, i.e. a merge of primecoin-hp and datacoin repositories.


Precompiled binaries are available in "Releases" section (

Datacoin High Performance Version 14

This is the hp14 release (encompassing changes from primecoin-0.1.2-hp14). Datacoin is a fork of Primecoin (

P.S. Please note, that the default donation behaviour has changed (according to changes in Primecoin). Now it is set to 1 percent of mined coins which is sent to the DTC address above. If you don't like it, change it in the sources or specify explicitly during the normal datacoind server start with (not documented in the help) options: -donationpercentage - default 1, and -donationaddress.

Donations are welcome if you want to support my work.

What is Primecoin?

Primecoin is an experimental cryptocurrency that introduces the first scientific computing proof-of-work to cryptocurrency technology. Primecoin's proof-of-work is an innovative design based on searching for prime number chains, providing potential scientific value in addition to minting and security for the network. Similar to Bitcoin, Primecoin enables instant payments to anyone, anywhere in the world. It also uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Primecoin is also the name of the open source software which enables the use of this currency.

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


Primecoin is released under conditional MIT license. See COPYING` for more information.

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 Bitcoin 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 ppcoin/primecoin forum (

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 Primecoin.


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

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.

See for how to create a test plan.
