Database tables for the “PoopCoin” app. I’ll provide a high-level schema for each table, and then we can delve into the SQL commands to create these tables.

### Database Schema:

1. **Users**:
– `UserID`: Unique identifier for each user.
– `Email`: User’s email address.
– `Password`: Hashed password for security.
– `PoopCoinBalance`: The amount of PoopCoin the user has earned.
– `MembershipStatus`: Whether the user is a regular or premium member.

2. **PoopReports**:
– `ReportID`: Unique identifier for each report.
– `ReporterUserID`: The user who reported the poop.
– `Latitude`: Latitude of the reported poop.
– `Longitude`: Longitude of the reported poop.
– `Status`: Whether the poop is reported, being cleaned, or cleaned.
– `Timestamp`: When the report was made.

3. **Images**:
– `ImageID`: Unique identifier for each image.
– `ReportID`: The report associated with the image.
– `ImageType`: Whether it’s a ‘before’ or ‘after’ image.
– `ImageURL`: URL where the image is stored (assuming cloud storage).

4. **Transactions**:
– `TransactionID`: Unique identifier for each transaction.
– `UserID`: The user who earned the PoopCoin.
– `Amount`: Amount of PoopCoin earned.
– `Timestamp`: When the transaction occurred.

### SQL Commands:

“`sql
— Users Table
CREATE TABLE Users (
UserID INT PRIMARY KEY AUTO_INCREMENT,
Email VARCHAR(255) NOT NULL UNIQUE,
Password VARCHAR(255) NOT NULL,
PoopCoinBalance FLOAT DEFAULT 0,
MembershipStatus ENUM(‘Regular’, ‘Premium’) DEFAULT ‘Regular’
);

— PoopReports Table
CREATE TABLE PoopReports (
ReportID INT PRIMARY KEY AUTO_INCREMENT,
ReporterUserID INT,
Latitude FLOAT NOT NULL,
Longitude FLOAT NOT NULL,
Status ENUM(‘Reported’, ‘Being Cleaned’, ‘Cleaned’) DEFAULT ‘Reported’,
Timestamp TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
FOREIGN KEY (ReporterUserID) REFERENCES Users(UserID)
);

— Images Table
CREATE TABLE Images (
ImageID INT PRIMARY KEY AUTO_INCREMENT,
ReportID INT,
ImageType ENUM(‘Before’, ‘After’) NOT NULL,
ImageURL VARCHAR(512) NOT NULL,
FOREIGN KEY (ReportID) REFERENCES PoopReports(ReportID)
);

— Transactions Table
CREATE TABLE Transactions (
TransactionID INT PRIMARY KEY AUTO_INCREMENT,
UserID INT,
Amount FLOAT NOT NULL,
Timestamp TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
FOREIGN KEY (UserID) REFERENCES Users(UserID)
);
“`

These tables should provide a solid foundation for the PoopCoin app. You can expand upon this schema by adding more fields or tables as needed. Remember to set up proper indexing and consider performance optimizations when the database grows.

Creating a full-fledged app like “PoopCoin” is a comprehensive project that would require extensive code, spanning multiple files and configurations.
This is a basic outline of the android app code

### 1. **Setup**:
Initialize a new Android project in Android Studio. Add the necessary dependencies in your `build.gradle`:

“`gradle
// Firebase
implementation ‘com.google.firebase:firebase-auth:…’
implementation ‘com.google.firebase:firebase-firestore:…’
implementation ‘com.google.firebase:firebase-storage:…’

// Google Maps
implementation ‘com.google.android.gms:play-services-maps:…’

// Web3j for Ethereum
implementation ‘org.web3j:core:…’
“`

### 2. **Firebase Initialization**:
In your `Application` class:

“`java
import com.google.firebase.FirebaseApp;

public class PoopCoinApp extends Application {
@Override
public void onCreate() {
super.onCreate();
FirebaseApp.initializeApp(this);
}
}
“`

### 3. **User Authentication**:
Using Firebase Authentication, you can set up a simple login and registration system:

“`java
import com.google.firebase.auth.FirebaseAuth;

FirebaseAuth mAuth = FirebaseAuth.getInstance();

// Register
mAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(this, task -> {
if (task.isSuccessful()) {
// Registration successful
} else {
// Registration failed
}
});

// Login
mAuth.signInWithEmailAndPassword(email, password)
.addOnCompleteListener(this, task -> {
if (task.isSuccessful()) {
// Login successful
} else {
// Login failed
}
});
“`

### 4. **Google Maps Integration**:
In your activity’s XML:

“`xml
<fragment
android:id=”@+id/map”
android:name=”com.google.android.gms.maps.SupportMapFragment”
android:layout_width=”match_parent”
android:layout_height=”match_parent”/>
“`

In your activity:

“`java
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.MarkerOptions;

SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(googleMap -> {
// Add a marker for a reported poop
googleMap.addMarker(new MarkerOptions().position(new LatLng(lat, lng)).title(“Reported Poop”));
});
“`

### 5. **Camera Integration**:
To capture an image:

“`java
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
“`

### 6. **Database Operations**:
Using Firestore:

“`java
import com.google.firebase.firestore.FirebaseFirestore;

FirebaseFirestore db = FirebaseFirestore.getInstance();

// Add a new report
Map<String, Object> report = new HashMap<>();
report.put(“location”, new GeoPoint(lat, lng));
report.put(“status”, “reported”);
db.collection(“reports”).add(report);
“`

### 7. **Cryptocurrency Integration**:
This is a bit more complex. You’d need to set up Ethereum nodes, create the PoopCoin token, and then use Web3j to interact with the blockchain.

—

This is just a starting point. A complete implementation would involve handling errors, creating a user-friendly UI, managing state, integrating other features, and thorough testing.

If you’re serious about this project, I’d recommend breaking it down into smaller tasks and tackling each one step by step. If you need assistance with specific parts or more detailed code snippets, please let me know!

The code provided for “PoopCoin” is a smart contract intended to be deployed on the Ethereum blockchain, not a standalone blockchain itself. Therefore, you don’t install this on a CentOS server like you would with traditional software. Instead, you deploy the contract to the Ethereum network. However, to interact with the Ethereum network from a CentOS server, you can set up a node or use infrastructure provided by services like Infura or Alchemy. Here’s a step-by-step guide to deploying the contract using an Ethereum node:

1. **Set Up the Development Environment:**

First, you’ll need to install the necessary tools to compile and deploy the smart contract. This typically involves installing Node.js, npm (Node.js package manager), and Truffle, which is a development framework for Ethereum.

“`bash
curl -sL https://rpm.nodesource.com/setup_14.x | sudo bash –
sudo yum install -y nodejs
sudo npm install -g truffle
“`

2. **Install an Ethereum Client:**

You’ll need an Ethereum client like Geth or OpenEthereum (formerly Parity) to interact with the Ethereum network.

“`bash
sudo yum install -y geth
“`

However, running a full node requires syncing the entire Ethereum blockchain, which is resource-intensive. For development purposes, it’s more practical to use a service like Infura.

3. **Initialize Your Project:**

Create a new directory for your project and initialize it with Truffle:

“`bash
mkdir PoopCoinProject
cd PoopCoinProject
truffle init
“`

Then, place your smart contract code in the `contracts` directory.

4. **Compile the Smart Contract:**

Use Truffle to compile the contract:

“`bash
truffle compile
“`

5. **Configure Network:**

Configure Truffle to connect to the Ethereum network. For production, you would set up a `.env` file with your Infura endpoint and private key:

“`javascript
// truffle-config.js
const HDWalletProvider = require(‘@truffle/hdwallet-provider’);
const infuraKey = “your_infura_key”;
const fs = require(‘fs’);
const privateKeys = [“your_private_key”]; // do not commit real private keys

module.exports = {
networks: {
// Configuration for mainnet
mainnet: {
provider: () =>
new HDWalletProvider(privateKeys, `https://mainnet.infura.io/v3/${infuraKey}`),
network_id: 1,
gasPrice: 10000000000,
},
// Configuration for testnet (Ropsten, in this case)
ropsten: {
provider: () =>
new HDWalletProvider(privateKeys, `https://ropsten.infura.io/v3/${infuraKey}`),
network_id: 3,
gas: 5500000,
confirmations: 2,
timeoutBlocks: 200,
skipDryRun: true
}
},
// …
};
“`

6. **Deploy the Contract:**

Create a migration script in the `migrations` directory to deploy your contract and use Truffle to deploy it to the network of your choice:

“`bash
truffle migrate –network ropsten
“`

This command will compile your contracts, deploy them to the Ropsten test network, and run any associated migration scripts.

Remember that deploying and interacting with smart contracts costs Ether for gas, even on testnets (where you can get Ether from faucets). Always test thoroughly on testnets before considering deploying to the main Ethereum network. Deploying a smart contract requires careful planning and understanding of Ethereum gas mechanics to avoid unnecessary costs.

For a production environment, or if you want to run an Ethereum node yourself on your CentOS server, you’d need to follow the Ethereum client installation instructions more precisely, manage the blockchain synchronization, and handle security configurations on your server, which are quite advanced tasks.
