Overview

The Dandelion Voting app is a fork of the Original Aragon Voting app. It serves the same purpose as the original Voting app but also enables organizations to restrict actions to members who have expressed approval in recent votes. It basically means that by voting yes on a proposal you are committing to a decision in the Org.

The main changes that have been implemented which differ from the original Voting app are:

• Removed the ability for a user to change their vote.
• Added a buffer period which determines how much time in blocks must pass between the start of each vote.
• Added an execution delay period in blocks (this means that the full vote duration + full execution delay period must pass before being able to execute a vote in case it passes).
• Removed the early execution functionality.
• Changed the vote duration to blocks. The main reason for this is that since proposals are queued we do not necessarily know which block number to use for the vote snapshot (since we are not necessarily processing the transaction right when the vote starts).
• Keep track of the latest vote ids users have voted yes on.
• Make the app an ACL Oracle.
