Delegate Hackathon Rewards

Over the past 3 weeks, builders have been extending the Juicebox protocol's pay and redeem functionality with data sources, which are contracts that pass custom data to the pay and redeem functions, and with delegates, which are contracts that define custom hooks to execute after a payment or redemption takes place.

Half of the funds in the Buidl Guidl Juicebox project (~9.1 ETH) will be paid out to entrants based on the results of this proposal – allocate votes to your favorite submissions as you see fit. To ask questions or see updates, visit the #🏰｜delegate-hackathon channel.

5. DominantJuice

submitted by Armand and electrone

The main juice of this project is adding a JB project option to use a dominant assurance escrow contract that quadruples as a JB Data Source, JB Pay Delegate, and JB Redemption Delegate. The escrow contract features Alex Tabarrok’s “dominant assurance” contract idea, which tries to minimize the "free-rider problem" by rewarding early pledgers with an owner-deposited refund bonus upon a failed campaign/cycle. If the funding target is met, the pledger's pledges turn into payments that fund the project, and the project owner withdraws their original refund bonus deposit from the escrow contract / JB Data Source. This alternative mechanism can be extended to fund any type of crowdfunding campaign or public good.
