User Story

As a user of the Arbor UI, I should be able to anonymously vote on several things throughout the app. Including but not limited to:

• Upvoting stems on a project’s stem queue for being used on the next available slot
• Upvoting popular Arbor projects
• Upvoting popular stems
• Remix competition community vote

Notes

Currently, there is an implementation for upvoting stems within a project’s stem queue, using Semaphore: https://github.com/semaphore-protocol/boilerplate

The stem queue voting code can be found here:

• UI - https://github.com/arbor-protocol/ui/blob/main/components/StemQueue/StemQueue.tsx#L77
• Smart Contract - https://github.com/arbor-protocol/ui/blob/main/web3/contracts/StemQueue.sol
