Crowdfunding Dapp

Ethereum Dapp that allows funding a project or venture by raising money from a large number of people.

The funding process consists of several steps:

1. Manager: Initially, a new campaign must be created and a minimum investment amount must be established. The person who creates the campaign becomes the manager of the campaign.

2. Investors: Individuals who wish to participate in an existing campaign can do so by investing a minimum contribution. All invested funds are collected into a pool, which is held in a smart contract.

3. Voting: To spend money from the pool the manager brings up proposal with detailed information about where the money goes and what the purpose of the expenses. Investors can then vote on whether or not the proposal should be funded.

4. Spend funds: The manager has the authority to approve and spend money from the pool only if a majority of investors have approved the spending proposal.
