Belenios is a verifiable voting system that partly implements the Helios-C protocol described here, which is itself derived from Helios.
It consists of a command-line tool and a web server. Both use the same backend and can be used to organize elections and perform verifications. They employ messages formatted in a common format, a specification of which is available in specification.pdf.
Compilation instructions are provided in INSTALL.
An election involves several roles: an administrator, a credential authority, trustees and voters. For maximum security, each of these roles must be performed by a different entity. An election can be summarized as follows:
Each step can be performed with the help of the command-line tool. The tool is also the most convenient way to exercise the verifiability capabilities of the system.

The whole process can be executed using the web server. Each step can be done with a browser. In this case, the formal "administrator" role above is typically shared between the server and a human operator. The server can also assume the roles of credential authority and trustee. Therefore, in its simplest (and weakest) form, an election involves only an operator henceforth called "election administrator" (usually distinct from the person who sets up and administrates the server itself) and voters. In its strongest form, an election involves the election administrator, a credential authority, (at least) two trustees and voters.
