# Proposal and Voting

The code is an Ethereum platform smart contract written in the Solidity programming language for a decentralized autonomous organization (DAO). In order to manage proposal submission, proposal voting, and organization governance, the contract specifies a number of activities and occasions.

The DAO contract uses an event-driven approach for members to submit proposals and vote on them. Members can submit a proposal by calling the `submitProposal` function, which creates a new proposal and stores it in the `proposals` mapping. The function requires the sender to be a member of the organization, and checks if the proposal limit has been reached and if the member has reached their individual proposal limit.

Voting on proposals is done by calling the `vote` function, which takes a proposal ID and a vote (either true or false) as arguments. The function updates the proposal's vote count and sets the `passed` field of the proposal to `true` if the vote count is greater than or equal to the quorum percentage of the number of members. Conversely, the `passed` field is set to `false` if the vote count is less than or equal to the negative of the quorum percentage. If the proposal passes, the `ProposalPassed` event is emitted, and if it fails, the `ProposalFailed` event is emitted.

Members may submit proposals and cast votes in favor of or against them within the terms of the contract. The Quorum % used in the voting process determines whether the motion has passed or failed. The proposal is deemed to have passed if it receives more votes in favor than the required percentage; otherwise, it is said to have failed. A system of events is also put into place by the contract to keep track of the status of proposals and members, including when a proposal is put forth, put to a vote, approved or rejected, and when a member is added or withdrawn.&#x20;

To monitor the status of the proposals and members, the contract makes use of various mapping and arrays. The contract also involves an array of checks to make sure that only parties with authorization may carry out tasks and that proposals haven't previously been carried out, reached a quorum, or been accepted by more than 50% of the voters.
