Create off-chain polling website for NDX holders

Gitcoin link

Reward: $2000 in DAI

If you build this using a decentralized database solution (e.g. 3box or similar) which does not require a hosted server, the reward will be increased by an additional $500 DAI.

Summary

Create a clone of StrawPoll using React where votes are weighted by users' NDX balances.

There should be three primary pages:

• A poll creation form (should be the home page)
• A voting interface for an existing poll
• A list of existing polls

Skills

• React
• Web3
• Express
• (optional) IPFS

How to measure balances

In order to measure the balance a user has in NDX in a manner that is not prone to manipulation, the website should query the user's balance from a specific Ethereum block. When a new poll is created, it should use a specific Ethereum block which is auto-filled using the latest Ethereum block or overridden by the user. The user's balance can then be queried to check what it was at the poll's starting block.

You can get this data by querying the Indexed governance subgraph for a user's balance and specifying in the query which block to check the balance for.

Indexed Governance Subgraph

The subgraph defines a TokenHolder struct which has a tokenBalance property - this is what we want. You can check the balance of a user for a block by querying:

{
  tokenHolder(
    id: {lower_case_user_address},
    block:{number: 11891558}
  ) {
    tokenBalance
  }
}

Poll Creation

Poll creation is where a user configures the settings for the new poll and specifies the question and choices.

If a user has not already connected their wallet, require them to do so before creating a poll.

The poll creation interface should have the following inputs:

• Input field for the poll question (required input)
• Input field for a short description of up to 400 characters (optional input)
• Input fields for each question
  • Some way of adding new questions (either a button or automatically when the user reaches the end of the current list)
• Checkbox to make the poll a multiple answer poll
• Input field for block number to use for balance snapshots
  • Auto-fill with latest Ethereum block number

Inspiration from StrawPoll

Poll Interface

Every poll should have a unique ID which can be used to go to its interface.

The polling interface should:

• Display the results if:
  • The user has not connected their wallet
  • The user has already voted
  • The poll has ended
• Display the voting interface otherwise

Vote Interface

• Poll question
• Description (if any)
• Checkbox for each option
• If it is a multiple choice poll, show "select all that apply" or something similar at the top
• If the user has a balance of 0, do not allow them to vote
• Submit button

Inspiration from StrawPoll

Results Interface

• Poll question
• Description (if any)
• Results for each option (# of votes and progress bar)
• Total number of individual voters
• Total votes cast (NDX used to vote)
• Option to open the list of voter receipts

Inspiration from StrawPoll

When the user submits their choice(s), require them to sign a typed message with the poll ID and their selection. Submit this data to a database, update the vote total and add the receipt (signature).

Inspiration

StrawPoll has an excellent user interface. Snapshot has most of the functionality we want for weighting votes by balance snapshots.
