The Sentiment-Influenced Voting System is an innovative blockchain-based project that redefines traditional voting by introducing emotion-driven decision dynamics. Built on the Flow Blockchain, this s
A decentralized sentiment-based voting system built on the Flow Blockchain, where real-time sentiment analysis influences the weight of each vote.
Each vote’s impact dynamically adjusts according to changing public sentiment — simulating real-world social influence in decision-making.
This smart contract introduces a unique concept:
Voting influenced by sentiment rather than equality.
Each voter can cast a single vote for a candidate, but the weight of that vote changes in real time depending on the current sentiment score, which can be updated by the contract owner (or an off-chain sentiment oracle).
Positive sentiment increases vote weight, while negative sentiment reduces it.
Sentiment automatically decays over time to ensure the voting system reflects real-time mood.
Blockchain: Flow Testnet
Smart Contract Language: Solidity (Flow-compatible wrapper or hybrid deployment)
Sentiment Mechanism: On-chain weighted scoring logic
Interaction Mode: No imports, no constructors, no input fields — parameterless and self-contained design.
Deployed Contract Address:
0xA6aB8F707006ef5385802D890D1e0C0C732DABe6
You can view and interact with the contract using the Flow Testnet explorer.
Contract / Component | Purpose | Network | Address |
|---|---|---|---|
| Core voting logic (sentiment-based) | Flow Testnet |
|
| Simulates real-time sentiment updates | Flow Testnet |
|
| External feed mock for testing | Flow Testnet |
|
💡 Note: Secondary contract addresses are for mock or test integration — may vary across redeployments.
✅ Dynamic Vote Weight: Vote strength adapts to sentiment score.
🕒 Real-Time Decay: Sentiment influence weakens automatically over time.
🧍 Single-Vote Enforcement: Prevents multiple votes by the same address.
🔐 Oracle-Controlled Updates: Only owner can adjust sentiment levels.
⚡ Parameterless Design: No function requires input fields, constructors, or imports.
Function | Description |
|---|---|

| Decreases global sentiment score by -1 |
| Resets sentiment score to neutral (0) |
| Parameterless vote functions for each candidate |
| View total votes for each candidate |
| Check what your vote weight would be if you voted now |
