SentimentVoting

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.

🚀 Overview

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.

🧱 Built On

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.

⚙️ Features

✅ 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.

📘 Core Functions

Function	Description
`increaseSentiment()`	Increases global sentiment score by +1
`decreaseSentiment()`	Decreases global sentiment score by -1
`resetSentiment()`	Resets sentiment score to neutral (0)
`voteAlice()` / `voteBob()` / `voteCarol()`	Parameterless vote functions for each candidate
`getVotesForAlice()` / `getVotesForBob()` / `getVotesForCarol()`	View total votes for each candidate
`currentVoteWeight()`	Check what your vote weight would be if you voted now

🧩 Use Cases

DAO Governance Systems – sentiment-weighted community decisions
Social Platforms – integrating public emotion into polls
Market or Trend Predictions – reflecting collective confidence dynamically

🧠 Future Enhancements

Integration with real-time AI sentiment APIs (e.g., Twitter, news, or token data)
Multi-round or category-based voting sessions
Off-chain to on-chain sentiment oracle using Flow Cadence script
