open source electronic cash
The opencoin project is about "digital cash". We develop a protocol to use the original idea of electronic cash in daily live. For this we also develop a system consisting of minting software, wallet software and everything that is necessary to have a system for anonymous electronic transactions.
opencoin defines standards and provides an implementation around the blind-signature system as invented by David Chaum, known as electronic cash / digicash. The software and specs are opensource under a GPL License.
Status of the project
We created a first draft of the protocol, which was reviewed by our crypto experts, and no obvious flaws were found. A legal report documents how an opencoin system could be used within the EU. We also created a sample implementation, mostly to test the protocol.
Curently we are rewriting the implemenation, to allow better documention and testing of the system. This leads to slight changes in the exchange of messages. We are also working on protocol additions to prepare the way for a proper beta version.
Other starting points
- Playground (web wallet server for testing)
- Installing the mobile phone wallet
- There are mailing lists we use for our communication
- A trac with our source code
- There is a subversion repository
- Other related projects we are aware of
