Do you already have ideas that you want to develop on Ethereum / Waves. Maybe you need help and some funds to bring them to life, but who would lend money to someone they don’t trust?
Using Ethereum / Waves, you can create a contract that will hold a contributor's money until any given date or goal is reached. Depending on the outcome, the funds will either be released to the project owners or safely returned back to the contributors. All of this is possible without requiring a centralized arbitrator, clearinghouse or having to trust anyone.
You can even use the token you created earlier to keep track of the distribution of rewards.
