Predictive Analytics Contract

# Predictive Analytics Smart Contract 📊🔮

Welcome to the Predictive Analytics Smart Contract! This is a simple and secure Solidity-based contract deployed on the *Edu Chain* to simulate trend prediction analytics. Whether you're exploring blockchain technology or looking to interact with AI-powered predictions, this contract serves as a great starting point.

## 🚀 Features of the Predictive Analytics Contract

### 1. Trend Prediction Storage:

- The contract can store a binary trend prediction where:

- 0 represents a downward trend.

- 1 represents an upward trend.

- Predictions are securely stored on the blockchain, ensuring transparency and immutability.

### 2. Real-Time Trend Updates:

- Trend predictions can be updated at any time using the updateTrendPrediction() function. This allows external systems (such as AI algorithms or oracles) to provide real-time trend data and predictions.

### 3. Public Access:

- Anyone can view the current trend prediction through the getTrendPrediction() function, ensuring that the contract’s state is transparent and publicly accessible.

### 4. Simple & Lightweight:

- No complex inputs or constructors during deployment.

- Ideal for learning how to integrate blockchain with trend prediction systems.

### 5. Event Logging:

- When the trend is updated, an event (TrendUpdated) is emitted to log the changes, making it easier for external services to track updates in real-time.

## 🛠 How to Use

Here’s how you can easily interact with the Predictive Analytics Contract:

### 1. View Current Trend:

- Call the getTrendPrediction() function to see the current trend prediction (either 0 or 1).

### 2. Update the Trend:

- Use the updateTrendPrediction(uint _prediction) function to set the trend.

- Pass 0 for a downward trend.

- Pass 1 for an upward trend.

- This can be used to simulate AI-based predictions or other external data sources.

> Note: This contract allows anyone to update the trend prediction. In real-world use, you would typically restrict this to trusted sources, such as oracles.

```solidity

// SPDX-License-Identifier: MIT

pragma solidity ^0.8.0;

contract TrendPrediction {

// State variable to store the trend prediction (1 for upward, 0 for downward)

uint public trendPrediction;

// Event to log when the trend is updated

event TrendUpdated(uint newPrediction);

// A function to update the trend prediction (This would be done by an external source like an oracle)

function updateTrendPrediction(uint _prediction) public {

trendPrediction = _prediction;

emit TrendUpdated(_prediction);

}

// Function to get the current trend prediction

function getTrendPrediction() public view returns (uint) {

return trendPrediction;

    }
