MongoDB Ditches Tradition, Pushes Developers to Download Software Separately.

Chidozie Zeno Ezeanekwe — Wed, 05 Apr 2023 11:26:56 +0000

Hey there developers! 👋🏾

If you're a fan of using MongoDB for your database needs, you may have noticed that the latest version 6 no longer comes bundled with mongo.exe But no worries, I'm here to guide you through the process of downloading and installing MongoDB and its shell, Mongosh for mongoDB to work.

First off,

head on over to the official MongoDB website,

scroll down,

and download the version of MongoDB that's right for you.

Make sure to choose the version compatible with your operating system.

Once you have the downloaded file, let's get started with the installation process:

Step 1: Install MongoDB

Double-click on the downloaded file to open the installer.
Follow the instructions on the screen to complete the installation process.
Once the installation is complete, you'll need to run the mongod process to start the MongoDB server. To do this, open up a terminal or command prompt and navigate to the bin directory within the MongoDB installation folder.

Mine was "C:\Program Files\MongoDB\Server{version_number}\bin".
Replace "{version_number}" with the version of MongoDB you have installed. the current version as at writing was 6.0

Then run the following command:

mongod.exe --dbpath "C:\data\db"

or

mongod --dbpath "C:\data\db"

This command will start the MongoDB server and use the directory "C:\data\db"(data directory with db directory inside) as the data directory for the server. If the directory does not exist, It will create it before running the command "mongod.exe" or "mongod".
you should see some output in the terminal indicating that it's running.

Note: Keep the Command Prompt or PowerShell window open and running

Step 2: Install Mongosh

Head over to the Mongosh download page

Download the zip file for your operating system.

Extract the contents of the zip file to the bin directory within the MongoDB installation folder.
Copy the Contents in the just zipped bin's folder and paste it in the mongoDB bin's folder.
Open up a terminal or command prompt and navigate to the bin directory within the MongoDB installation folder.

To start using Mongosh, run the following command:

mongosh

And that's it!

You should now be able to start working with your MongoDB database using the Mongosh shell.

So there you have it, a simple and straightforward guide on how to download and install MongoDB and Mongosh. Happy coding!"

The Case Against Infura and Alchemy: The Hidden Dangers of Centralized Third-Party Services.

Chidozie Zeno Ezeanekwe — Fri, 10 Feb 2023 11:09:28 +0000

Hello, dear Blockchain Enthusiasts!

Today, we are going to talk about the dangers of using Infura and Alchemy when building your DApp.

As a decentralized application (dapp) builder, you’ve likely heard of Infura and Alchemy. They are popular tools for developers who need to connect to an Ethereum network. However, what you may not know is that Infura and Alchemy can be a double-edged sword.

Let’s dive into why these popular tools can be a problem for dapp builders:

Centralization

Infura and Alchemy are centralized services that control the data flow between your dapp and the Ethereum network. This means that a single point of failure exists in your dapp’s architecture, making it vulnerable to security threats and data breaches.

Data Leaks

When using Infura and Alchemy, sensitive data such as private keys and smart contract addresses are transmitted to a third-party server. This puts your dapp’s data at risk of being leaked or intercepted by malicious actors.

Limited Functionality

Infura and Alchemy are not designed to be full-fledged Ethereum nodes, which means they may not provide the same level of functionality as a locally run node. This can limit your dapp’s capabilities and restrict your ability to scale.

and many more...

So, what’s the solution?

It’s important to understand that Infura and Alchemy should only be used for specific purposes. Infura can be used for database purposes and Alchemy can be used for remote procedure calls (RPCs). However, it is advised against using Alchemy for RPCs and instead use the Chainlist website to get public RPCs for any mainnet or testnet.

Why Chainlist?

Chainlist is a decentralized Ethereum network explorer that provides public RPCs for any mainnet or testnet. Unlike Infura and Alchemy, Chainlist is not centralized, which means that your dapp data will not be transmitted to a third-party server. Additionally, Chainlist provides the same level of functionality as a locally run Ethereum node, making it a more secure and scalable solution.

In conclusion, while Infura and Alchemy can be convenient tools for dapp builders, they also come with significant drawbacks. If you’re looking to build a secure and scalable dapp, it’s recommended that you use Infura only for database purposes and Chainlist for RPCs. By taking this approach, you’ll avoid the dangers of centralization, data leaks, and limited functionality, and build a dapp that is ready for the future.

The Pause Procedure: Protecting Your Contract from Hackers.

Chidozie Zeno Ezeanekwe — Fri, 10 Feb 2023 10:48:40 +0000

You know you can actually PAUSE your smart contract in case of security breach, right?

... Wait! you dont know?!
I've got you,
Let me walk you through.

For Starters,

Smart contracts are basically self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code.
They provide a secure, transparent, and immutable environment for executing transactions. But

In some cases, it may become necessary to temporarily pause the contract, for example, in case of a security breach or to make updates.

In this blog post, we'll explore different ways to pause a smart contract in Solidity 0.8 and when to use each one. We'll also provide code examples for each method.

Method 1: Pausing a Contract Using a Boolean Flag

The simplest and most straightforward way to pause a contract is to use a Boolean flag. You can create a variable paused of type bool in your contract and set its value to true to pause the contract. When the value is set to false, the contract is resumed.

Here's an example of how to do this:

pragma solidity 0.8.0;

contract Pausable {
    // Create a variable to store the pause state
    bool private paused = false;

    // Function to pause the contract
    function pause() public {
        // Check if the caller is the contract owner
        require(msg.sender == owner, "Only the owner can pause the contract");
        // Set the pause state to true
        paused = true;
    }

    // Function to resume the contract
    function resume() public {
        // Check if the caller is the contract owner
        require(msg.sender == owner, "Only the owner can resume the contract");
        // Set the pause state to false
        paused = false;
    }

    // Check the pause state before executing a transaction
    function executeTransaction() public {
        // If the contract is paused, do not execute the transaction
        require(!paused, "The contract is paused. Transactions cannot be executed.");
        // Execute the transaction
        // ...
    }
}

In the example above, the pause function is used to set the paused flag to true. The resume function is used to set the flag back to false. In the executeTransaction function, we check the value of paused before executing any transactions. If the contract is paused, the transaction is not executed.

Method 2: Pausing a Contract Using the Emergency Stop Mechanism

Another way to pause a smart contract is to use the emergency stop mechanism. This mechanism allows the contract owner to halt all contract operations in the case of an emergency. To implement this, you can create a stop function in your contract that sets a flag indicating that the contract is stopped.

Here's an example of how to do this:

pragma solidity 0.8.0;

contract EmergencyStop {
    // Create a variable to store the stop state
    bool private stopped = false;

    // Function to stop the contract
    function stop() public {
        // Check if the caller is the contract owner
        require(msg.sender == owner, "Only the owner can stop the contract");
        // Set the stop state to true
        stopped = true;
    }

    // Function to resume the contract
    function resume() public {
        // Check if the caller is the contract owner
        require(msg.sender == owner, "Only the owner can resume the contract");
// Set the stop state to false
stopped = false;
}

// Check the stop state before executing a transaction
function executeTransaction() public {
    // If the contract is stopped, do not execute the transaction
    require(!stopped, "The contract is stopped. Transactions cannot be executed.");
    // Execute the transaction
    // ...
}
}

In the example above, the stop function is used to set the stopped flag to true. The resume function is used to set the flag back to false. In the executeTransaction function, we check the value of stopped before executing any transactions. If the contract is stopped, the transaction is not executed.

Method 3: Pausing a Contract Using a Modifier

A modifier is a special type of function in Solidity that can be used to add additional behavior to existing functions. In the case of pausing a contract, you can create a paused modifier that checks the pause state before executing a transaction.

Here's an example of how to do this:

pragma solidity 0.8.0;

contract PausableModifier {
// Create a variable to store the pause state
bool private paused = false;
// Function to pause the contract
function pause() public {
    // Check if the caller is the contract owner
    require(msg.sender == owner, "Only the owner can pause the contract");
    // Set the pause state to true
    paused = true;
}

// Function to resume the contract
function resume() public {
    // Check if the caller is the contract owner
    require(msg.sender == owner, "Only the owner can resume the contract");
    // Set the pause state to false
    paused = false;
}

// Modifier to check the pause state before executing a transaction
modifier pausedOnly {
    // If the contract is paused, do not execute the transaction
    require(!paused, "The contract is paused. Transactions cannot be executed.");
    // Execute the transaction
    _;
}

// Use the pausedOnly modifier in the executeTransaction function
function executeTransaction() public pausedOnly {
    // Execute the transaction
    // ...
}
}

In the example above, the pausedOnly modifier is used to check the value of paused before executing a transaction. If the contract is paused, the transaction is not executed. The executeTransaction function uses the pausedOnly modifier, so it automatically checks the pause state before executing the transaction.

Conclusion

In this blog post, we've explored three different methods for pausing a smart contract in Solidity 0.8. Each method has its own advantages and disadvantages, so it's up to you to decide which one is best for your use case. Whether you use a boolean flag, the emergency stop mechanism, or a modifier, make sure to thoroughly test your code before deploying it to the mainnet.

I hope this post has been helpful in showing you how to pause a smart contract in Solidity 0.8.

Avoiding Security Vulnerabilities: The tx.origin vs msg.sender Debate

Chidozie Zeno Ezeanekwe — Sat, 28 Jan 2023 18:42:10 +0000

In the world of Ethereum, it is crucial to understand the difference between tx.origin and msg.sender.
These two variables are often used to determine the identity of the sender of a transaction, but they have different use cases and can lead to different security risks if used incorrectly. In this post, we will explore the differences between tx.origin and msg.sender, and show code examples of how an attacker can take advantage of the wrong use of tx.origin.
We will also provide code examples to show the best ways to use tx.origin and msg.sender.

What is tx.origin?

tx.origin is a variable that represents the original sender of a transaction. It is the address of the account that originally created the transaction and sent it to the network. This variable is useful when creating smart contracts that need to verify the authenticity of a transaction, such as when implementing a multisig wallet

function isValidTransaction(address _sender) public view returns (bool) {
    return _sender == tx.origin;
}

In the example above, the function isValidTransaction takes an address as an input and compares it to the tx.origin. If the two match, the function returns true, indicating that the transaction is valid.

What is msg.sender?

msg.sender is a variable that represents the current sender of a message or transaction. It is the address of the account that sent the current message or transaction to the smart contract. This variable is useful when creating smart contracts that need to determine the current sender of a message, such as when implementing an access control system.

function isAuthorized(address _sender) public view returns (bool) {
    return _sender == msg.sender;
}

In the example above, the function isAuthorized takes an address as an input and compares it to the msg.sender. If the two match, the function returns true, indicating that the sender is authorized.

The security disadvantage of using tx.origin the wrong way

While tx.origin is useful for verifying the authenticity of a transaction, it can also be a security risk if used incorrectly. One common mistake is to use tx.origin instead of msg.sender when implementing an access control system.

// victim's contract
function transferEther() public {
    require(msg.sender == tx.origin, "Unauthorized access");
    // transfer ether code
}

In the example above, the function transferEther uses tx.origin to check if the sender is authorized to perform the transfer. However, this is incorrect because tx.origin **represents the original sender of the transaction, not the current sender. An attacker can take advantage of this by creating a malicious contract that calls the **transferEther function on behalf of the original sender.

contract Attacker {
    function attack() public {
        address victim = address(this);
        victim.call(bytes4(keccak256("transferEther()")));
    }
}

In the example above, the Attacker contract creates a transaction to call the transferEther function on the victim contract. Since the tx.origin is the address of the Attacker contract and not the original sender, the require **statement in the **transferEther function(in the victim's contract) will pass and the attacker will be able to successfully transfer ether from the victim contract.

This highlights the importance of using msg.sender instead of tx.origin when implementing an access control system. msg.sender represents the current sender of the message or transaction, and ensures that the correct account is being checked for authorization.

function transferEther() public {
    require(msg.sender == authorizedAccount, "Unauthorized access");
    // transfer ether code
}

In the example above, the function transferEther uses msg.sender to check if the sender is authorized to perform the transfer. This ensures that only the authorized account can transfer ether from the contract, and prevents malicious contracts from bypassing the access control system.

So when to use tx.origin? 🤔

tx.origin should be used when the smart contract needs to verify the authenticity of a transaction. This includes cases such as multisig wallets or contracts that need to ensure that a transaction was created by a specific address.

function confirmTransaction(bytes32 _hash) public {
    require(tx.origin == multisigWallet, "Invalid confirmation");
    // confirm transaction code
}

In the example above, the function confirmTransaction uses tx.origin to ensure that the confirmation is coming from the correct multisig wallet. This prevents malicious contracts from confirming transactions on behalf of the multisig wallet.

And when do we use msg.sender?

msg.sender should be used when the smart contract needs to determine the current sender of a message or transaction. This includes cases such as access control systems or contracts that need to track the actions of a specific address.

function addAdmin(address _newAdmin) public {
    require(msg.sender == owner, "Unauthorized access");
    admins[_newAdmin] = true;
}

In the example above, the function addAdmin **uses **msg.sender to ensure that the request to add a new admin is coming from the contract owner. This prevents malicious contracts from adding new admins on behalf of the contract owner.

In conclusion,

it is important to understand the difference between tx.origin and msg.sender, as well as when and how to use them correctly. Using tx.origin incorrectly in an access control system can lead to security vulnerabilities, while using msg.sender correctly can help to secure the contract. Always be cautious and double check your code when using these variables.

APIs in SOLIDITY Smart Contracts: Is this even possible?!

Chidozie Zeno Ezeanekwe — Mon, 16 Jan 2023 22:09:37 +0000

Is it possible to use APIs in Solidity Smart Contracts?

The answer is yes.
APIs or Application Programming Interfaces are a way for applications to communicate with each other and exchange data. Over the years, developers have become more and more familiar with APIs and their use in developing applications.

In the context of Solidity Smart Contracts

using APIs can be a powerful tool to enhance the functionality of a Smart Contract. APIs can be used to access external data sources and perform various tasks, such as executing trades, sending and receiving payment, and more.

The most common way to use APIs in Solidity Smart Contracts is with an Oracle.

An oracle in Solidity can be implemented as a smart contract, allowing it to connect to external data sources and provide data to other Smart contracts on the Ethereum blockchain.

This is particularly useful for smart contracts that need to interact with external data, such as stock prices, weather, or even sports scores.

So why is it easier to create oracles in Solidity 0.8 and above?

The main reason is that Solidity 0.8 introduced a new feature called "external function calls", which allows smart contracts to call functions in other smart contracts. This means that we can create a smart contract that acts as an oracle, and other smart contracts can call that oracle to access external data.

In this article, we will be discussing how to use a weather API to power a smart contract - how to set up a weather API, and use it to power a smart contract.

The following code example shows how to connect to a weather API in Solidity.

//SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;


// Create a contract to connect to the weather API
contract WeatherApi {
 // Store the API key
 string apiKey;

 // constructor to set the API key
 constructor(string _apiKey) public {
  apiKey = _apiKey;
 }

 // Function to connect to the API
 function getWeatherData() public returns (string result) {
  // Make an HTTP request to the API
  bytes memory response = http.post(weatherApiURL, json.encode(apiKey));

  // If the response is valid, store the result
  if (response.length > 0) {
   result = response.toString();
  }
  // If the response is not valid, throw an error
  else {
   require(false, "Error connecting to weather API");
  }

  // Return the result
  return result;
 }
}

The code above creates a contract to connect to a weather API. The constructor takes in an API key and stores it in the apiKey variable. The getWeatherData() function makes an HTTP request to the API and stores the response in a result variable. If the response is not valid, the function throws an error. Once the result is stored, it is returned from the function.

Using the Weather API in Other Smart Contracts

Once the WeatherApi contract is set up, it can be used in other smart contracts to power them with real-world data.

The following code example shows how to use the WeatherApi contract in another smart contract.

//SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

// Create a contract to use the WeatherApi
contract WeatherSmartContract {
 WeatherApi weatherApi;

 // Constructor to set the WeatherApi
 constructor(address _weatherApi) public {
  weatherApi = WeatherApi(_weatherApi);
 }

 // Function to get the current temperature
 function getCurrentTemperature() public returns (uint result) {
  // Call the WeatherApi and store the result
  string memory response = weatherApi.getWeatherData();

  // Parse the response to get the temperature
  uint temperature = parseTemperature(response);

  // Return the temperature
  return temperature;
 }

 // Helper function to parse the response
 function parseTemperature(string memory response) private returns (uint temperature) {
  // Parse the response to get the temperature
  // Code to parse the response goes here

  // Return the temperature
  return temperature;
 }
}

The code above creates a contract to use the WeatherApi contract. The constructor takes in the address of the WeatherApi contract and stores it in the weatherApi variable. The getCurrentTemperature() function calls the WeatherApi contract to get the weather data, parses the response to get the temperature, and returns the temperature.

However, it’s important to note that using APIs in Solidity Smart Contracts can be a risky endeavor. As with any type of code, it’s important to ensure that your Smart Contract is properly tested and includes robust error handling. This will help to ensure that the Smart Contract is secure and that it operates as expected.

Debugging Your Code: A Guide to Common Errors in Programming and How to Avoid Them.

Chidozie Zeno Ezeanekwe — Sat, 14 Jan 2023 12:02:26 +0000

Are you getting frustrated trying to write code that is robust and reliable?

Don't worry, we've all been there! Knowing how to recognize and avoid the most common programming errors can help you save time and headaches in the long run.

In this post, we'll take a look at some of the most common errors in programming, with JavaScript as our case study.

header image from: https://www.zilliondesigns.com/blog/bringing-4xx-user-experience-errors-to-life/

image: (https://hexlet.io/courses/intro_to_programming/lessons/errors/theory_unit)

Most Common Errors in programming are;

Syntax Errors,
Type Errors,
Name Errors,
Index Errors,
Value Errors,
Attribute Errors,
Key Errors,
Import Errors,
IO Errors and
Runtime Errors.

We'll explain what each of these errors are, how to recognize them, and how to avoid them.

Let's take a look at each of these errors in the context of JavaScript and see how they can be avoided.

Syntax Errors

image from (https://dev-to-uploads.s3.amazonaws.com/uploads/articles/)

Syntax Errors occur when the code written is not valid in the programming language. This can happen due to incorrect punctuation, missing parentheses, or an incorrect keyword. For example, in JavaScript, if you forget to close a bracket, you would get a syntax error.

// Incorrect Syntax
let x = 10

// Correct Syntax
let x = 10;

Type Errors

image: (https://www.google.com/url?sa=i&url=https%3A%2F%2Fstackoverflow.com%2Fquestions%2F48839524%2Fhow-to-resolve-javascript-not-a-function-error&psig=AOvVaw0UvRD3YSBVPzr5YXhRQVj5&ust=1673784219719000&source=images&cd=vfe&ved=0CBAQjRxqFwoTCOjx8KCCx_wCFQAAAAAdAAAAABAE)

Type Errors occur when data is used in a way that is not supported by the programming language. In JavaScript, this usually happens when a value is not the correct type. For example, if you try to use a string as an array index, you would get an error.

// Incorrect Syntax
let arr = [1,2,3];
let index = "two";

// TypeError: Cannot read property 'two' of undefined
let val = arr[index];

// Correct Syntax
let arr = [1,2,3];
let index = 1;
let val = arr[index]; // val = 2

Name Errors

Name Errors occur when a variable or function is not defined. In JavaScript, this usually happens when you try to use a variable or function that has not been declared.

// Incorrect Syntax

// ReferenceError: myFunction is not defined
let x = myFunction();

// Correct Syntax
function myFunction() {
  return "Hello World";
}
// x = "Hello World"
let x = myFunction();

Index Errors

Index Errors occur when you try to access an element of an array or object that does not exist. In JavaScript, this usually happens when you try to access an index of an array that is out of bounds.

// Incorrect Syntax
let arr = [1,2,3];

// IndexError: Index out of bounds
let val = arr[4];

// Correct Syntax
let arr = [1,2,3];

// val = 3
let val = arr[2];

Value Errors

Value Errors occur when a variable or function is used in a way that is not valid in the programming language. In JavaScript, this usually happens when a value is not of the correct type or is out of range.

// Incorrect Syntax
let x = "Hello";

// TypeError: Cannot convert string to number
let y = x + 1;

// Correct Syntax
let x = "Hello";

// y = "Hello World"
let y = x + " World";

Attribute Errors

Attribute Errors occur when an attribute or property of an object is not valid or does not exist. In JavaScript, this usually happens when you try to access a property of an object that does not exist.

// Incorrect Syntax
let obj = {
  name: "John"
};
// TypeError: Cannot read property 'age' of undefined
let age = obj.age;

// Correct Syntax
let obj = {
  name: "John",
  age: 30
};
 // age = 30
let age = obj.age;

Key Errors

Key Errors occur when a key used to access an element of a dictionary or map is not valid or does not exist. In JavaScript, this usually happens when you try to access a key of an object that does not exist.

// Incorrect Syntax
let obj = {
  name: "John"
};
// TypeError: Cannot read property 'age' of undefined
let age = obj["age"];

// Correct Syntax
let obj = {
  name: "John",
  age: 30
};
// age = 30
let age = obj["age"];

Import Errors

Import Errors occur when a module or library is not found or cannot be imported. In JavaScript, this usually happens when you try to use a module or library that has not been installed or is not in the correct path.

// Incorrect Syntax

// Error: Cannot find module 'myModule'
import myModule from "myModule"; 

// Correct Syntax
import myModule from "./myModule";

IO Errors

IO Errors occur when a file or resource is not found or cannot be read. In JavaScript, this usually happens when you try to read a file that does not exist or is not in the correct path.

// Incorrect Syntax

// Error: ENOENT: no such file or directory
let data = fs.readFileSync("myFile.txt");

// Correct Syntax
let data = fs.readFileSync("./myFile.txt");

Runtime Errors

Runtime Errors occur when an unexpected error occurs while the program is running. In JavaScript, this usually happens when an unexpected value or type is encountered or an unexpected operation is performed.

// Incorrect Syntax
let x = 1;

// TypeError: Cannot convert string to number
let y = x + "Hello";

// Correct Syntax
let x = 1;
let y = x + 2; // y = 3

By understanding what type of errors can occur in programming, and how to recognize and avoid them, you can ensure that your code is robust and reliable. By taking the time to debug your code and check for issues, you can save yourself a lot of time and headaches in the long run.

The Dark side of Decentralized Apps: Is Your Data actually Yours, is it Secure?

Chidozie Zeno Ezeanekwe — Fri, 13 Jan 2023 22:15:02 +0000

You read right...

Is Your Data actually Yours, is it Secure?

Decentralized applications (dApps) are making waves in the world of technology and finance. These applications are gaining in popularity due to their promise of decentralization, autonomy, and security. But are these applications actually decentralized? In this post, we’ll dive into the underlying technologies of dApps and why many of them are not actually decentralized.

Decentralization

Let’s start by defining what decentralization means. Decentralization is a system where there is no single entity in control of the system. It is an architecture where there is no central authority. With decentralization, no one party has control over the system. The idea is that the system is run and maintained by a network of nodes, which are computers or nodes that are connected to the network.

So, if a dApp is decentralized, it should be run and maintained by a network of nodes, right? Not necessarily. Many dApps are not actually decentralized. They are run by centralized services such as Alchemy, Pinata, Binance, and many others. These services act as gatekeepers to the dApp, and they control access to the dApp. This means that these services can control who can use the dApp and what they can do with it. They can also collect data from users and use it for their own purposes.

The problem with this is that it defeats the purpose of decentralization. The whole point of decentralization is to provide autonomy to users, but with centralized services controlling access, users are not given the autonomy they should have. Furthermore, these services can collect data from users without their knowledge or consent, and they can use this data as they please. This goes against the privacy and security of users, as their data can be used for purposes that they may not have agreed to.

In addition to this, decentralized applications are also vulnerable to security risks. Since the blockchain technology that powers decentralized applications is still relatively new, there are security risks that haven’t been fully examined. This means that the data stored on the blockchain could be vulnerable to attacks from malicious actors. Furthermore, the security of the blockchain itself is still open to debate.

Finally, data has become one of the most valuable commodities in today’s world. Companies are willing to pay a lot of money for data, as it can be used to target users with specific ads and even influence their buying decisions. This means that companies like Alchemy, Pinata, and Binance can use the data they collect from users to make money. This is not the decentralized future that many envisioned for dApps.

Are dApps really decentralized?

So, are dApps really decentralized? The answer is no.
Many dApps are controlled by centralized services that are collecting user data and using it for their own purposes. Furthermore, the blockchain technology that powers dApps is still relatively new and vulnerable to security risks. Finally, data has become one of the biggest business commodities, and companies are willing to pay a lot of money for it. This means that these centralized services can use the data they collect from users to make money.

It’s important to remember that decentralization is not the same as autonomy. Many dApps are not truly decentralized, as they are controlled by centralized services. This means that users are not given the autonomy they should have, and their data can be used for purposes that they may not have agreed to. Therefore, it’s important to understand the underlying technologies of dApps and why many of them are not actually decentralized.

Take - away

Cutting back on third-party applications when building dapps can give users the ultimate flexibility when interacting with them. So, let's reduce those third-party apps and give our users the best experience possible!
