Pure PHP implementation of Hashcash 1.

Project Outlines

The project outlines as described in my blog post about Open Source Software Collaboration.

  • The main purpose of this software is to implement Hashcash using pure PHP.
  • The features should not go beyond the features and functions the original implementation of Hashcash is providing. So the feature-set is kind of restricted what could be possible in the future. But still, feel free to request features.


The preferred method of installation is via Packagist and Composer. Run the following command to install the package and add it as a requirement to composer.json:

composer.phar require thefox/hashcash


See examples.php for more examples.

require 'vendor/autoload.php';
use TheFox\Pow\Hashcash;
$stamp = Hashcash::newInstance(20, '')->mint();
print "hashcash stamp: '".$stamp."'\n";

Alternative Usage

require 'vendor/autoload.php';
use TheFox\Pow\Hashcash;
$hashcash = new Hashcash(20, '');
print "hashcash stamp: '".$hashcash->mint()."'\n";
