Votorola
Votorola is software for building consensus and reaching decisions in public. Installed in a local town or region, it functions both as a primary electoral system for nominating candidates, and a primary rule-making system for voting up laws, plans and policies. The technical backbone is a peer-to-peer voting mechanism that allows for recursive delegation and continuous vote shifting. The voter lists are authenticated by a neighbourhood trust network. Votorola is currently in alpha. Coding platform: Java, Apache Wicket. Deployment platform: Linux, Tomcat, MediaWiki, PostgreSQL. Votorola is open source software available under the MIT licence.
