# Voting System & Anonymity
|
|
|
|
> **Status**: ✅ Complete · **Priority**: High · **Created**: 2026-03-16 · **Tags**: voting, core
|
|
|
|
## Overview
|
|
|
|
Core voting functionality: participants can add options to a poll and cast votes. Supports both anonymous and non-anonymous modes as configured at poll creation. Votes are sent to the poll owner via PeerJS.
|
|
|
|
## Design
|
|
|
|
### Adding Options
|
|
|
|
- Participants and above can add options while the poll is `open`
|
|
- Options have text only (keep it simple)
|
|
- Owner validates the sender has permission before accepting
|
|
|
|
### Casting Votes
|
|
|
|
- V1: single-choice (one vote per participant). Data model uses `optionId: string` which can later be extended to `optionIds: string[]` for multi-choice or a ranked array for ranked-choice.
|
|
- Vote is signed with voter's private key for authenticity
|
|
- In anonymous mode: owner records the vote but strips `voterId` before storing
|
|
- In non-anonymous mode: `voterId` is stored alongside the vote
|
|
- Vote changes: a participant can change their vote while the poll is open (replaces previous)
|
|
|
|
### Results
|
|
|
|
- Results are visible to all roles (viewers included)
|
|
- Show: option text, vote count, percentage
|
|
- Non-anonymous: also show who voted for what
|
|
- Results update in real-time via PeerJS messages
|
|
|
|
### Vote Flow
|
|
|
|
```
|
|
Participant Owner (relay)
|
|
│ │
|
|
│─── poll:vote ───────────────▶│ validate permission
|
|
│ │ if anonymous: strip voterId
|
|
│ │ store vote
|
|
│◀── poll:state:update ───────│ broadcast updated results
|
|
```
|
|
|
|
## Plan
|
|
|
|
- [ ] Build "add option" UI and message handler
|
|
- [ ] Build voting UI (option list with vote button)
|
|
- [ ] Implement vote submission (sign + send to owner)
|
|
- [ ] Owner-side vote processing (validate, anonymize if needed, store)
|
|
- [ ] Build results display (bar chart or simple percentage view)
|
|
- [ ] Implement vote change (replace previous vote)
|
|
|
|
## Test
|
|
|
|
- [ ] Participant can add an option
|
|
- [ ] Participant can cast a vote
|
|
- [ ] Anonymous vote does not leak voter identity
|
|
- [ ] Results update in real-time across connected peers
|
|
- [ ] Vote change replaces (not duplicates) previous vote
|
|
- [ ] Viewers can see results but not vote
