Sentiment-Influenced Voting Smart Contract

A simple Solidity smart contract that allows users to vote on a proposal, with vote weights influenced by sentiment analysis scores.

Since sentiment analysis cannot be performed on-chain, this contract accepts a manually submitted sentiment score (from -100 to +100), which is used to dynamically calculate vote weight.

📌 Features

• ✅ No imports

• ✅ No constructors

• ✅ No input parameters

• ✅ Fully on-chain vote counting

• 🧠 Off-chain sentiment score can be submitted manually

• ⚖️ Votes are weighted based on sentiment (positive = higher weight)

🔧 How It Works

1. Sentiment Score Submitted
   A sentiment score between -100 and +100 is pushed to the contract using updateSentimentScore().

2. Users Vote
   Users cast a "yes" or "no" vote using the vote(bool voteYes) function. Their vote is automatically weighted based on the current sentiment score.

3. Result Calculation
   The contract calculates the winner based on the total weighted votes.

🛠️ Functions
