Decentralized Voting System

On-chain governance with transparent vote tracking

Problem

Traditional voting systems lack transparency and are vulnerable to manipulation. Centralized systems create trust issues.

Solution

A Solana-based voting system where votes are recorded immutably on-chain, ensuring transparency, verifiability, and resistance to tampering.

System Architecture

Stateless program design where vote data is stored in PDA accounts. Each proposal gets a unique account, and votes are recorded as separate accounts linked to voter keys.

On-Chain Responsibilities

  • Proposal creation and metadata
  • Vote recording (immutable)
  • Vote counting and validation
  • Proposal state management

Off-Chain Responsibilities

  • UI for proposal creation
  • Vote submission interface
  • Results visualization
  • Indexing and analytics

Wallet Interaction Flow

1

User connects wallet

2

Creates proposal via frontend

3

Frontend constructs instruction

4

Wallet signs transaction

5

Transaction submitted to RPC

6

Program validates and processes

7

Vote recorded in PDA account

Tradeoffs

  • ▸On-chain storage costs SOL per vote
  • ▸Limited to simple voting mechanisms (complex logic is expensive)
  • ▸Requires wallet for every interaction

Future Improvements

  • ▸Implement vote delegation
  • ▸Add quadratic voting support
  • ▸Create off-chain indexer for faster queries
  • ▸Add proposal categories and filtering
