Mastering Git Commit Messages: Best Practices and Markdown Usage

Imam Abubakar — Mon, 24 Jul 2023 05:27:04 +0000

In the world of software development, effective communication is essential for a smooth collaboration among team members. One crucial aspect of this communication is writing Git commit messages. These messages serve as concise summaries of the changes made in a commit and can greatly impact the overall project's maintainability and understanding. Let's dive into the art of crafting clear, informative, and well-structured Git commit messages.

Why Commit Messages Matter

Before we dive in, let's understand why Git commit messages are so crucial. Clear and well-written commit messages provide the following benefits:

Understanding Changes: A descriptive commit message helps team members quickly grasp the nature of the changes without the need to read the actual code changes immediately.
Browsing History: When browsing through the project's history, meaningful commit messages serve as signposts, making it easier to find specific changes or trace the development of a feature.
Collaboration and Onboarding: Well-explained commit messages facilitate smoother collaboration among team members and assist newcomers in understanding the codebase more efficiently.

Best Practices for Writing Commit Messages

Be Specific and Concise: Clearly describe the changes made in the commit in a concise manner. Avoid vague terms or overly technical jargon.

Bad Example: "Fixed a bug."

Good Example: "Resolved null pointer exception in UserController."

Use the Imperative Mood: Write commit messages in the imperative mood, as if giving a command. This maintains consistency and reads more naturally.

Bad Example: "Fixing a bug in the authentication module."

Good Example: "Fix bug in authentication module."

Include Motivation and Context: Provide a brief explanation of why the change was made and any relevant context for better understanding.

Example:

   Refactor user authentication to improve security.

   With the growing number of users, we noticed potential security vulnerabilities in the previous authentication process. This commit introduces a more robust and secure authentication mechanism.

Separate Subject from Body: Divide your commit message into a subject and a body, separated by a blank line. The subject should be a short description (up to 50 characters) while the body provides additional details.

Example:

   Implement user profile page

   - Added HTML and CSS for the profile layout.
   - Integrated API calls to fetch user data dynamically.
   - Implemented edit functionality for profile information.

Use Bullet Points for Multiple Changes: If a commit involves multiple changes, use bullet points in the commit body to list them clearly.
Reference Issue Tracker (if applicable): If your project uses an issue tracker like JIRA or GitHub issues, consider referencing the issue number in the commit message.

Example: "Fix bug in authentication module (Issue #123)."

Markdown Usage in Commit Messages

While commit messages are typically plain text, some platforms support basic Markdown formatting. Here are some examples of using Markdown in commit messages:

Emphasis: Use asterisks or underscores to emphasize/bold text. Example: *fix* or _fix_.
Links: Add links to external references or related commits using [title](url).
Code Blocks: When referring to code snippets, use triple backticks for code blocks.

Remember to check your project's guidelines or the platform's documentation for supported Markdown features.

Conclusion

Writing Git commit messages might seem trivial, but it's a skill that significantly impacts collaboration and codebase maintenance. Following these best practices and incorporating Markdown where possible will enhance the clarity and professionalism of your commit messages, leading to a more cohesive and efficient development process.

Becoming a Blockchain Developer: Experiences, Challenges, and Beyond

Imam Abubakar — Wed, 19 Jul 2023 11:52:10 +0000

As a curious developer with a penchant for emerging technologies, my journey into the captivating world of blockchain and web3 development mainly started in 2020 and was marked by fascination and determination. I'm excited to share my personal experiences, the challenges I encountered, and the remarkable journey that awaits those who choose to become blockchain developers.

My first steps on becoming a blockchain developer started with the Binance Masterclass: Developers’ Edition in early 2021, which was a 2-month online programme that really helped me learn. Although, after that, I took to further learning mostly on YouTube and Udemy, which involved immersing myself in the core concepts that underpin this revolutionary technology. Understanding decentralised networks and distributed ledgers helped me appreciate the groundbreaking nature of blockchain. Learning about cryptographic hashing and consensus algorithms such as Proof of Work (PoW) and Proof of Stake (PoS) revealed the inner workings of the blockchain's trustless nature and transaction validation process.

Undoubtedly, one of the most significant challenges was diving into the realm of smart contract development. These self-executing contracts are the backbone of decentralised applications (dApps) on the blockchain. Mastering languages like Solidity or Vyper demanded a paradigm shift in programming, as I had to adapt to the nuances of coding in a decentralised environment, especially coming from a Javascript background where strong typing isn’t really a thing. However, the rewards of creating smart contracts that automated complex processes and eliminated intermediaries made it all worthwhile.

Later on, to harness the full potential of blockchain, I ventured into exploring popular platforms at the time like Ethereum, Hyperledger, and EOS. Each platform had its own unique strengths and suited different use cases. Ethereum's thriving ecosystem and support for smart contracts made it a prime choice for developing dApps and launching Initial Coin Offerings (ICOs). Hyperledger, with its focus on enterprise solutions, provided me with insight into the potential of blockchain in industries like supply chain management and healthcare. And EOS, with its high throughput and developer-friendly approach, opened doors to exciting possibilities in gaming and social media.

Also, as a blockchain developer, understanding security and cryptography is crucial. Working with private and public keys, encrypting data, and securing transactions became second nature. The decentralized nature of blockchain demands robust security measures to safeguard sensitive information and prevent potential vulnerabilities.

Honestly, the blockchain landscape evolves at a breathtaking pace, with new protocols like ZkEVM and advancements emerging regularly. Engaging with the vibrant blockchain community through forums, attending conferences, and networking on social media proved to be invaluable. These interactions not only helped me stay up-to-date but also exposed me to diverse perspectives and novel ideas.

The most rewarding aspect of being a blockchain developer is the ability to work on projects with real-world impact. From improving financial inclusion to enhancing data transparency, blockchain technology has the potential to transform various industries. Contributing to projects that empower individuals, streamline processes, and create positive change has been immensely fulfilling.

Why Become a Blockchain Developer?

The motivation to become a blockchain developer is multifaceted, depending on what your goal is. It's the desire to be part of a groundbreaking movement that challenges traditional norms, promotes transparency, and fosters decentralised solutions. The joy of solving complex problems and the excitement of creating innovative solutions in a dynamic space fuel the passion for blockchain development. (Btw, you can make money, like a lot.)

Conclusion

Embracing the blockchain developer roadmap has been an awe-inspiring journey of growth and exploration. From understanding the fundamental principles to building real-world applications, every step has been a testament to the potential of blockchain technology. Aspiring developers who embark on this path will find themselves at the forefront of technological progress, shaping a future that is decentralized, equitable, and transformative.

What is Solidity?

Solidity is a statically-typed programming language designed for developing smart contracts that run on the Ethereum Virtual Machine (EVM). Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They allow trusted transactions and agreements to be carried out among disparate, anonymous parties without the need for a central authority, legal system, or external enforcement mechanism.

Setting Up Your Environment

Before you start coding, you'll need to set up your development environment. The most common tools for Solidity development are:

Remix IDE: An online IDE specifically built for smart contract development with built-in static analysis, test blockchain, and debugging tools.

Truffle: A popular development framework with built-in smart contract compilation, linking, deployment, and binary management.

Ganache: A personal blockchain for Ethereum development you can use to deploy contracts, develop applications, and run tests.

To get started, head over to Remix IDE on your browser.

Basic Syntax and Structure

A Solidity smart contract is similar to a class in object-oriented languages. Each contract can contain declarations of State Variables, Functions, Function Modifiers, Events, and Struct Types. Here's a basic structure of a Solidity contract:

pragma solidity ^0.8.0;

contract MyContract {
    // State variables
    uint256 public myVariable;

    // Events
    event ValueUpdated(uint256 newValue);

    // Constructor
    constructor() {
        myVariable = 0;
    }

    // Function modifiers
    modifier onlyOwner() {
        require(msg.sender == owner, "Only contract owner can call this function");
        _;
    }

    // Functions
    function setValue(uint256 newValue) public onlyOwner {
        myVariable = newValue;
        emit ValueUpdated(newValue);
    }
}

In the above example:

The contract is declared using the contract keyword followed by the contract name MyContract.
The pragma directive specifies the compiler version to be used (in this case, Solidity version 0.8.0 or higher).
The myVariable state variable is declared as a publicly accessible uint256.
The ValueUpdated event is defined, which will be emitted whenever the value of myVariable is updated.
The constructor initializes myVariable to 0 when the contract is deployed.
The onlyOwner modifier is defined to restrict access to certain functions, allowing only the contract owner to call them.
The setValue function is defined, which updates the value of myVariable with the provided newValue. It can only be called by the contract owner due to the onlyOwner modifier.
The emit keyword is used to trigger the ValueUpdated event and emit the new value.

Note: This example shows a simplified structure of a Solidity contract. In real-world scenarios, smart contracts may have more complex functionality, additional state variables, multiple functions, and interactions with other contracts or external systems.

Data types

Data Type	Description	Example
`bool`	Boolean value (`true` or `false`)	`bool myBool = true;`
`uint`	Unsigned integer	`uint256 myUint = 42;`
`int`	Signed integer	`int256 myInt = -10;`
`address`	Ethereum address	`address myAddress = 0x123...7890;`
`string`	Textual data	`string myString = "Hello, Solidity!";`
`array`	Collection of elements of the same type	`uint256[] myDynamicArray;`
`mapping`	Key-value pairs	`mapping(address => uint256) balances;`
`struct`	Custom data structure	`struct Person { string name; uint256 age; } Person myPerson = Person("Alice", 25);`
`enum`	Enumerated list of possible values	`enum Status { Active, Inactive, Suspended } Status myStatus = Status.Active;`

// Contract showcasing Solidity data types
pragma solidity ^0.8.0;

contract DataTypeExample {
    bool public myBool;
    uint256 public myUint;
    int256 public myInt;
    address public myAddress;
    string public myString;
    uint256[] public myDynamicArray;
    mapping(address => uint256) public balances;
    struct Person {
        string name;
        uint256 age;
    }
    Person public myPerson;
    enum Status { Active, Inactive, Suspended }
    Status public myStatus;

    constructor() {
        myBool = true;
        myUint = 42;
        myInt = -10;
        myAddress = 0x123...7890;
        myString = "Welcome to Hack Solidity!";
        myDynamicArray.push(1);
        balances[msg.sender] = 1000;
        myPerson = Person("Alice", 25);
        myStatus = Status.Active;
    }
}

State Variables

State variables are an important concept in Solidity as they represent the persistent storage of data within a smart contract. These variables hold their values between function calls and are stored on the blockchain. Here's an extensive overview of state variables in Solidity:

1.Declaration:

contract MyContract {
    uint256 public myVariable; // Public state variable
    address private owner;     // Private state variable
    uint256 internal myInternalVariable; // Internal state variable
    string public constant myConstant = "Welcome to Hack Solidity!"; // Public constant state variable
}

2.Visibility Modifiers: The visibility modifier determines how the state variable can be accessed.

public: The variable is accessible from within the contract and externally.
private: The variable is only accessible within the contract and not externally.
internal: The variable is accessible within the contract and any derived contracts.
external: The variable is only accessible externally and not within the contract.

3.Accessing State Variables: State variables can be accessed and modified by both internal and external functions within the contract.

Internal Access:

function updateVariable(uint256 newValue) internal {
    myVariable = newValue;
}

External Access:

function getVariable() external view returns (uint256) {
    return myVariable;
}

4.Constant State Variables: Constant state variables hold values that remain the same throughout the execution of the contract. They can be used for storing fixed values or configuration data.

string public constant GREETING = "Hello!";
uint256 public constant MAX_VALUE = 100;

Note that constant state variables can only be of types bool, int, uint, address, string, or arrays of these types.

5.Default Values: State variables are assigned default values if not explicitly initialized in the constructor or elsewhere.

For value types (bool, uint, int, etc.), the default value is 0.
For address, the default value is address(0).
For string, the default value is an empty string ("").
For reference types (arrays, structs, etc.), the default value is an empty instance.

Functions

Functions in Solidity are an essential part of smart contracts. They define the behavior and operations that can be performed on a contract's data. Here's an overview of functions in Solidity:

1.Function Declaration:

contract MyContract {
    // Public function without parameters and return value
    function myFunction() public {
        // Function body
    }

    // External function with parameters and return value
    function add(uint256 a, uint256 b) external pure returns (uint256) {
        // Function body
        return a + b;
    }
}

2.Visibility Modifiers: Functions can have visibility modifiers that control their accessibility.

public: The function can be called internally from within the contract and externally from other contracts or accounts.
private: The function is only accessible from within the contract.
internal: The function is accessible from within the contract and any derived contracts.
external: The function can be called externally, but not from within the contract itself.

3.Function Parameters:

function myFunction(uint256 param1, address param2) public {
    // Function body
}

4.Return Values: Functions can return values using the returns keyword, followed by the return type. Multiple return values can be specified using parentheses.

function getSumAndDifference(uint256 a, uint256 b) public pure returns (uint256, uint256) {
    uint256 sum = a + b;
    uint256 difference = a - b;
    return (sum, difference);
}

5.Function Modifiers: Modifiers are used to modify the behavior of functions. They are defined separately and can be applied to functions using the modifier keyword.

modifier onlyOwner() {
    require(msg.sender == owner, "Only contract owner can call this function");
    _;
}

function myFunction() public onlyOwner {
    // Function body
}

6.Function Overloading: Solidity supports function overloading, which means you can have multiple functions with the same name but different parameter lists. The compiler determines which function to call based on the provided arguments.

function process(uint256 data) public {
    // Function body
}

function process(uint256[] memory dataArray) public {
    // Function body
}

7.Fallback and Receive Functions: Solidity allows defining a fallback function and a receive function in a contract.

Fallback Function: The fallback function is executed when a contract receives a message without any matching function or value transfer. It is declared without a function name using the fallback keyword.

fallback() external {
    // Fallback function body
}

Receive Function: The receive function is executed when a contract receives a plain Ether transfer without any data. It is declared without a function name using the receive keyword.

receive() external payable {
    // Receive function body
}

Events

Events allow external applications to listen to and react to specific occurrences within the contract. Here's an overview of events in Solidity:

1.Event Declaration:

contract MyContract {
    // Event declaration with parameters
    event MyEvent(address indexed sender, uint256 value);
}

2.Event Emission: To emit an event and provide the associated data, you can use the emit keyword followed by the event name and the corresponding values.

function myFunction() public {
    // Emitting an event
    emit MyEvent(msg.sender, 100);
}

3.Event Parameters: Events can include parameters that define the information to be emitted. These parameters can be indexed or non-indexed.

Indexed Parameters: Indexed parameters enable efficient filtering and searching of events. Up to three parameters can be indexed per event.

event MyEvent(address indexed sender, uint256 indexed id, string message);

Non-indexed Parameters: Non-indexed parameters are included in the event but cannot be used for filtering.

event MyEvent(address sender, uint256 value, string message);

4.Event Subscription: External applications or other contracts can subscribe to events emitted by a contract and listen for specific occurrences. They can do this by using the contract's address and the event's signature.

// Event subscription example
MyContract myContract = MyContract(contractAddress);
myContract.MyEvent().listen(callbackFunction);

5.Event Log: When an event is emitted, a log entry is created on the blockchain, capturing the event's data. Event logs are stored in the transaction receipt and can be accessed using web3 libraries or blockchain explorers.

6.Event Usage: Events are commonly used for logging and providing information about specific state changes or significant occurrences within a contract. They serve as a means of communication between contracts and external systems, facilitating real-time updates and data synchronization.

contract MyContract {
    event ValueUpdated(uint256 newValue);

    uint256 public myValue;

    function setValue(uint256 newValue) public {
        myValue = newValue;
        emit ValueUpdated(newValue);
    }
}

In the above example, the ValueUpdated event is emitted whenever the setValue function is called, allowing external applications to listen to the event and receive updates whenever myValue is changed.

Struct

Structs in Solidity allow you to define custom data structures to group related variables. Here's a brief overview:

1.Struct Declaration: Structs are declared using the struct keyword within the contract scope.

struct Person {
    string name;
    uint256 age;
}

2.Struct Usage: Structs can be used to create instances and access their variables.

Person public myPerson;

function createPerson(string memory _name, uint256 _age) public {
    myPerson = Person(_name, _age);
}

3.Struct Arrays: Structs can be used to create arrays holding multiple instances.

Person[] public people;

function addPerson(string memory _name, uint256 _age) public {
    Person memory newPerson = Person(_name, _age);
    people.push(newPerson);
}

4.Nested Structs: Structs can be nested within other structs.

struct Person {
    string name;
    uint256 age;
    Address contactAddress;
}

struct Address {
    string street;
    string city;
}

Person public myPerson;

function createPerson(string memory _name, uint256 _age, string memory _street, string memory _city) public {
    Address memory newAddress = Address(_street, _city);
    myPerson = Person(_name, _age, newAddress);
}

Control structures in Solidity

1.If-Else Statements: If-else statements allow you to conditionally execute code based on a certain condition.


function checkValue(uint256 value) public pure returns (string memory) {
    if (value > 10) {
        return "Value is greater than 10";
    } else if (value == 10) {
        return "Value is equal to 10";
    } else {
        return "Value is less than 10";
    }
}

2.While Loop: While loops execute a block of code repeatedly as long as a specified condition is true.

function countDown(uint256 startValue) public pure returns (uint256) {
    while (startValue > 0) {
        startValue--;
    }
    return startValue;
}

3.For Loop: For loops allow you to execute a block of code repeatedly for a specific number of iterations.

function sumArray(uint256[] memory numbers) public pure returns (uint256) {
    uint256 sum = 0;
    for (uint256 i = 0; i < numbers.length; i++) {
        sum += numbers[i];
    }
    return sum;
}

4.Do-While Loop: Do-while loops execute a block of code at least once and continue executing as long as a specified condition is true.

function countUp(uint256 startValue) public pure returns (uint256) {
    do {
        startValue++;
    } while (startValue < 10);
    return startValue;
}

Error Handling

1.require Statement: The require statement is used to validate conditions and revert the transaction if the condition evaluates to false. It is commonly used for input validation and contract pre-conditions.

function deposit(uint256 amount) public {
    require(amount > 0, "Amount must be greater than zero");
    // Deposit logic
}

2.assert Statement: The assert statement is used to check for conditions that should never be false. If the condition evaluates to false, it indicates an internal error in the contract, and the transaction is reverted.

function divide(uint256 numerator, uint256 denominator) public pure returns (uint256) {
    assert(denominator != 0);
    return numerator / denominator;
}

3.revert Statement: The revert statement allows you to explicitly revert the transaction and provide an optional error message. It is typically used for explicit error handling and can include custom error messages to provide more information.

function withdraw(uint256 amount) public {
    if (amount > balance) {
        revert("Insufficient balance");
    }
    // Withdraw logic
}

4.Error Propagation: Errors can be propagated from one function to another by using the revert statement or by propagating them through return values or events. It is important to handle and propagate errors appropriately to ensure contract integrity.

function transfer(address recipient, uint256 amount) public {
    require(balance >= amount, "Insufficient balance");
    // Transfer logic
    if (errorOccurred) {
        revert("Transfer failed");
    }
}

Inheritance and Interfaces

1.Inheritance:
Inheritance allows a contract to inherit properties and functions from another contract, referred to as the base or parent contract. This promotes code reuse and enables contracts to build upon existing functionality. To inherit from a contract, the is keyword is used followed by the name of the parent contract.

contract ParentContract {
    // Parent contract variables and functions
}

contract ChildContract is ParentContract {
    // Child contract variables and functions
}

The child contract ChildContract inherits all the variables and functions from the parent contract ParentContract. It can also override inherited functions or add new functions.

2.Interfaces:
Interfaces define a set of function signatures that must be implemented by any contract that adopts the interface. They provide a way to define standardized communication protocols between contracts. Interfaces do not contain any function bodies; they only specify the function names, input parameters, and return types.

interface MyInterface {
    function myFunction(uint256 value) external;
    function myOtherFunction() external view returns (uint256);
}

Contracts that adopt an interface must implement all the functions defined in the interface. This ensures that contracts conform to a specific set of requirements and can interact with each other based on the interface's defined functions.

contract MyContract is MyInterface {
    function myFunction(uint256 value) external {
        // Implementation of myFunction
    }

    function myOtherFunction() external view returns (uint256) {
        // Implementation of myOtherFunction
    }
}

In this example, MyContract implements the functions defined in MyInterface. It provides the necessary function implementations to comply with the interface's requirements.

Global Variables

Global Variable	Description
`msg.sender`	The address of the sender of the current message (current caller or contract).
`msg.value`	The amount of ether (in wei) sent with the current message.
`msg.data`	The complete calldata of the current message.
`block.number`	The current block number.
`block.timestamp`	The timestamp of the current block (in seconds since the Unix epoch).
`block.difficulty`	The difficulty of the current block.
`block.coinbase`	The address of the miner who mined the current block.
`block.gaslimit`	The gas limit of the current block.
`tx.origin`	The address of the sender of the transaction (originating external user).
`address(this)`	The address of the current contract.
`address payable(this)`	The payable address of the current contract, allowing sending and receiving of ether.
`this.balance`	The balance (in wei) of the current contract.

Imports and Libraries

In Solidity, importing other contracts and using libraries are important mechanisms for code organization, modularity, and reusability. Here's an overview of import statements and libraries in Solidity:

1.Import Statements:
Import statements are used to include external Solidity files or libraries into your contract. They allow you to access the code and definitions from the imported files within your contract.

import "./MyContract.sol"; // Importing a local file
import "github.com/username/MyLibrary.sol"; // Importing a file from a remote location

By using import statements, you can break your code into separate files, import external contracts, or include libraries to leverage existing functionality.

2.Libraries:
Libraries are reusable code components in Solidity that allow you to define and deploy shared utility functions. They are similar to contracts but cannot have any storage variables or receive Ether. Libraries are typically used to reduce code duplication and provide commonly used functionalities.

library MathLibrary {
    function add(uint256 a, uint256 b) internal pure returns (uint256) {
        return a + b;
    }
}

To use a library, you can either deploy it as a separate contract or use the using keyword to attach it to a data type. The using keyword allows you to access library functions as if they were member functions of the data type.

using MathLibrary for uint256;

function myFunction(uint256 a, uint256 b) public pure returns (uint256) {
    return a.add(b); // Accessing library function
}

In the above example, the MathLibrary provides the add function, which can be accessed using the using keyword on the uint256 data type.

It's worth noting that starting from Solidity version 0.8.0, external libraries are preferred over internal libraries. External libraries are deployed separately and linked to the contract during deployment, whereas internal libraries are included within the bytecode of the contract itself.

ABI

Function	Description
`abi.decode(bytes memory encodedData, (...)) returns (...)`	ABI-decodes the provided data. The types are given in parentheses as the second argument. Example: `(uint256 a, uint256[2] memory b, bytes memory c) = abi.decode(data, (uint256, uint256[2], bytes))`
`abi.encode(...) returns (bytes memory)`	ABI-encodes the given arguments
`abi.encodePacked(...) returns (bytes memory)`	Performs packed encoding of the given arguments. Note that this encoding can be ambiguous!
`abi.encodeWithSelector(bytes4 selector, ...) returns (bytes memory)`	ABI-encodes the given arguments starting from the second and prepends the given four-byte selector
`abi.encodeCall(function functionPointer, (...)) returns (bytes memory)`	ABI-encodes a call to `functionPointer` with the arguments found in the tuple. Performs a full type-check, ensuring the types match the function signature. The result is equal to `abi.encodeWithSelector(functionPointer.selector, (...))`
`abi.encodeWithSignature(string memory signature, ...) returns (bytes memory)`	Equivalent to `abi.encodeWithSelector(bytes4(keccak256(bytes(signature))), ...)`

Cryptographic Functions

Function	Description
`keccak256(bytes memory) returns (bytes32)`	Compute the Keccak-256 hash of the input.
`sha256(bytes memory) returns (bytes32)`	Compute the SHA-256 hash of the input.
`ripemd160(bytes memory) returns (bytes20)`	Compute the RIPEMD-160 hash of the input.
`ecrecover(bytes32 hash, uint8 v, bytes32 r, bytes32 s) returns (address)`	Recover the address associated with the public key from an elliptic curve signature. Returns zero on error.
`addmod(uint256 x, uint256 y, uint256 k) returns (uint256)`	Compute `(x + y) % k` where the addition is performed with arbitrary precision and does not wrap around at 2^256. Assert that `k != 0`.
`mulmod(uint256 x, uint256 y, uint256 k) returns (uint256)`	Compute `(x * y) % k` where the multiplication is performed with arbitrary precision and does not wrap around at 2^256. Assert that `k != 0`.

Solidity Version Pragma

The Solidity version pragma is a statement used to specify the version of the Solidity compiler for contract compilation. It ensures compatibility and avoids potential issues due to breaking changes. Here are examples:

pragma solidity ^0.8.0;: Specifies compatibility with Solidity version 0.8.0 or higher (excluding 0.9.0).
pragma solidity 0.8.7;: Explicitly uses Solidity version 0.8.7.

5 coding habits you need to stop!

Imam Abubakar — Wed, 24 May 2023 10:59:49 +0000

Habits play an important part in molding our programming skills and productivity. As developers, we frequently slip into code habits that stifle our progress and limit our capabilities. In this post, I'd like to share my personal story as well as shed light on five coding habits that I had to break in order to improve my coding skills. You can improve your coding skills and become a more efficient developer by understanding the negative impact of these behaviors and embracing good improvements.

Habit 1: Writing Long and Complicated Functions

When I first started coding, I had a habit of writing long and complex functions. I believed that complicated code was required to solve complex problems. Long functions, on the other hand, are difficult to understand, debug, and maintain. I increased code readability and made my applications easier to understand and troubleshoot by using a more modular approach and splitting my code into smaller units with clear responsibilities.

Here's why you should stop writing long and complicated functions:

Lengthy functions make it difficult to understand the code at a glance.
Maintaining and updating such functions becomes a daunting task, leading to potential errors.
Debugging complex functions becomes time-consuming and challenging, especially when issues arise.

For example:

// Long and complex function
function calculateTotalPrice(products) {
  let totalPrice = 0;

  for (let i = 0; i < products.length; i++) {
    let product = products[i];

    if (product.quantity > 0 && product.price > 0) {
      totalPrice += product.quantity * product.price;
    }
  }

  return totalPrice;
}

// Refactored into smaller, modular functions
function calculateProductPrice(product) {
  if (product.quantity > 0 && product.price > 0) {
    return product.quantity * product.price;
  }

  return 0;
}

function calculateTotalPrice(products) {
  let totalPrice = 0;

  for (let i = 0; i < products.length; i++) {
    totalPrice += calculateProductPrice(products[i]);
  }

  return totalPrice;
}

In the example above, we start with a long and complex function called calculateTotalPrice. It iterates over an array of products, calculates the total price based on their quantity and price, and returns the result.

By refactoring the code, we break it down into smaller functions. The calculateProductPrice function calculates the price for an individual product, and the calculateTotalPrice function now utilizes this smaller function to calculate the total price for all products. This approach improves code readability, maintainability, and allows for reusability of the calculateProductPrice function elsewhere in the codebase.

By adopting this habit of breaking down code into smaller, modular functions, we can make our code more manageable and pave the way for better code organization and understandability.

Habit 2: Neglecting Code Documentation

Documentation is frequently regarded as a time-consuming process that may be easily postponed or ignored. I used to do this because I thought my code was self-explanatory, and honestly up until a few years ago, I didn't usually document my code. This technique, however, caused uncertainty for both myself and other developers working on a project. Adopting comprehensive documentation not only made it easier to understand and adjust my code in the future, but it also improved cooperation with coworkers, lowering development time and boosting overall product quality. If you don't know where to start, check out the links below:

Habit 3: Failing to Write Unit Tests

For many years, I thought unit testing was a waste of time that would only slow down my development process, especially when I'm freelancing on a project and the timeline is very short. However, I quickly recognized the enormous value of writing unit tests thanks to a very good friend. I noticed that by investing time early to establish detailed test cases, my code became more reliable, bug-free, and easier to maintain in the long term, especially since I switched to typescript. It's safe to say that part of the current criteria for getting a developer job nowadays includes unit testing and you might increase your chances of getting a job with just that. Unit testing also helped me refactor my code with confidence, knowing that I wouldn't introduce new issues by accident. This habit shift provided important peace of mind, a good night sleep and code stability.

Habit 4: Not Seeking Criticism/Assistance

I used to operate in isolation as a coder, rarely seeking help or criticism from other developers, mostly because I was an introvert, but that was not a substantial reason not to try. I thought that relying entirely on my own abilities would suffice and that apart from StackOverflow, StackExchange or GeeksforGeeks I would not need anyone's help or assistance either while trying to debug codes or finalizing a cool project.

Honestly, my coding abilities skyrocketed as I began aggressively seeking input from friends and professional developers, and that has helped me a lot in my career and improving my skillset (psst! My secret superpower is debugging other people's code). Feedback from people helped me gain new insights, identify potential weaknesses, and learn more efficient coding strategies.

Habit 5: Ignoring Version Control

One of my biggest career mistakes was not using GitHub back in 2016, when all my peers were using it. I overlooked the usefulness of version control systems like Git. I frequently found myself manually copying and saving code files with multiple names, which resulted in a disorganized and error-prone codebase. I started using GitHub in 2019, and I acquired the capacity to track changes, collaborate smoothly with others, and easily return to previous working versions by implementing version control methods. This habit increased my productivity and assisted in maintaining code integrity throughout the development process. So whether you are just starting out or you have been developing for a while now and you aren't using version control or aren't interested in using it, you are really getting behind. The best part is that you can start using Git right away.

Breaking coding habits might be difficult, but the benefits are enormous. I saw a substantial improvement in my coding abilities by reducing long and complex functions, embracing good documentation, using version control, creating unit tests, and seeking assistance and feedback. These habits boosted my productivity, reduced bugs, improved teamwork, and made me a more effective developer in general. So, take a step back, evaluate your own coding habits, and dare to break free from the ones that are stifling you. Your coding journey will thank you.

Thanks for reading.

Harnessing the Power of AI and Blockchain Together: The Ultimate Collaboration

Imam Abubakar — Tue, 14 Mar 2023 13:00:44 +0000

Introduction

I have personally witnessed how technology can change businesses and communities as a software developer and entrepreneur. Recently, I have been researching several cutting-edge technologies, including blockchain and artificial intelligence (AI). Although each technology has its own distinctive traits and capabilities, they can complement one another in a variety of ways, forming a potent pair that can propel the digital transformation of economies and society. I'll share my knowledge and experiences on the many applications of AI and blockchain, their benefits and drawbacks, practical examples, and potential future applications in this article.

You may have heard the terms artificial intelligence (AI) and blockchain technology, but what do they mean?

AI refers to the ability of computers to learn from data and make decisions based on that learning. Essentially, it involves teaching computers to do tasks that would typically require human intelligence, such as recognizing speech, images, and patterns, making predictions, and solving problems. AI has become increasingly prevalent in our daily lives, from virtual assistants like Siri and Alexa to personalized recommendations on social media platforms and online shopping websites.

Blockchain, on the other hand, is a digital ledger that records transactions in a secure and transparent way. Think of it as a digital version of a ledger book that records every transaction made within a network of computers. What makes Blockchain unique is that once a transaction is recorded, it cannot be altered or deleted. This makes it an ideal technology for applications that require transparency, security, and decentralization, such as cryptocurrency transactions, supply chain management, and voting systems.

Now, with that understanding, let's go over a solution that combines AI and Blockchain. let's say you're a farmer who wants to sell your produce to a buyer in a different country. Traditionally, the process of shipping and tracking the produce can be complicated and unreliable, with several intermediaries involved, and the buyer might be concerned about the quality and freshness of the product.

By using AI and Blockchain together, you can create a system that tracks your produce from the moment it's harvested until it reaches the buyer. An AI-powered system can monitor the temperature, humidity, and other factors that affect the quality of the produce during transportation. Meanwhile, a Blockchain-based system can record all the transactions, ensuring transparency and immutability. The buyer can then access the records and verify the quality and freshness of the produce before accepting the shipment. This system would make the entire process more efficient, transparent, and trustworthy for both the farmer and the buyer.

If that solution does not feel understandable to you, I have a more descriptive example we can go over together. Let's imagine you're a healthcare provider and you want to improve patient care while protecting their privacy. With AI and Blockchain, you can create a system that securely stores patient health data and provides insights that can help doctors make better diagnoses and treatment decisions.

Using AI algorithms, the system can analyze patient data, such as medical records, test results, and genetic information, to identify patterns and trends that may not be apparent to humans. The insights generated by the AI can be recorded on a Blockchain-based system, which ensures the data is secure, tamper-proof, and accessible only to authorized parties.

Doctors can then use these insights to develop personalized treatment plans for each patient, taking into account their unique medical history and genetic makeup. Patients can also access their health data securely and share it with other healthcare providers as needed, knowing that their privacy is protected by the Blockchain.

This system would improve the quality of patient care while ensuring that sensitive health data remains private and secure. It would also help researchers and policymakers gain insights into health trends and identify potential public health risks.

Examples and Use-cases Using AI and Blockchain Together

Supply Chain Management

Supply chain management can be revolutionized by AI and Blockchain by establishing a more effective, transparent, and safe system. Let's examine how AI and Blockchain can be applied to supply chain management as well as the advantages they provide and some examples of its use in practice.

Let's first examine how AI can enhance supply chain management. Many of the time-consuming and tedious operations involved in supply chain management, such monitoring inventory levels, forecasting demand, and streamlining transportation, can be automated by AI-powered solutions. This speeds up the procedure, lowers costs, and lowers the likelihood of errors.

For real-time supply chain insights, AI algorithms may analyze data from a variety of sources, including as sensors, RFID tags, and social media. These data can be applied to pinpoint possible bottlenecks, improve supply paths, and more precisely predict demand.

Let's now examine the ways in which blockchain can improve supply chain management. Systems built on the blockchain offer a transparent and secure way to record transactions, which makes them perfect for supply chain management. Every transaction is documented in a decentralized, tamper-proof ledger, making it simpler to monitor products and confirm their legitimacy.

A Blockchain-based system, for instance, can record each stage of the transit of goods from the maker to the final consumer. Supply chain managers can immediately see potential delays, bottlenecks, or fraudulent actions thanks to this.

Supply chain management may be made even more effective and secure by merging AI and Blockchain. Blockchain data may be analyzed by AI to deliver real-time insights into the supply chain. In turn, the Blockchain can safeguard the data and offer accountability and openness.

One real-life example of AI and Blockchain in supply chain management is IBM's Food Trust. This platform uses Blockchain technology to trace the origin of food products, ensuring their safety and quality. The platform enables food producers, suppliers, retailers, and regulators to track the movement of food from farm to table, ensuring its authenticity, safety, and freshness.

Another example is Walmart's Blockchain-based system, which tracks the movement of goods from the supplier to the store. The system enables Walmart to identify potential delays or quality issues quickly, reducing the risk of foodborne illnesses and ensuring customer satisfaction.

By automating tasks, providing real-time insights, and securing data, AI and Blockchain can help businesses reduce costs, improve customer satisfaction, and ensure the safety and authenticity of their products.

Healthcare Systems

Blockchain and AI can change the healthcare sector by offering safe and effective methods for collecting, processing, and exchanging medical data. Let's examine the advantages of using AI and blockchain in healthcare systems, as well as some practical examples of its use.

Let's start by considering how AI can make healthcare systems better. Medical data can be analyzed by AI-powered systems to find trends, diagnose diseases, and create individualized treatment plans. This data includes medical records, test findings, and imaging studies. This can assist medical professionals in providing patients with better care while also lowering costs.

AI may also be used to automate many of the time-consuming and laborious activities involved in healthcare, such as arranging appointments, monitoring patient data, and processing insurance claims. This lowers administrative expenses and gives medical professionals more time to concentrate on patient care.

Let's now examine how blockchain can improve healthcare delivery systems. Systems built on the blockchain offer a safe and open way to share and store medical data. Every transaction is recorded in a decentralized, tamper-proof ledger, facilitating the secure exchange of medical data while protecting patient privacy.

A blockchain-based system, for instance, can be used to store medical records, enabling patients and healthcare professionals to securely access their medical histories from any location in the globe. This can enhance care quality, lower the chance of errors, and minimize expenses.

Healthcare systems can be made even more effective and safe by fusing AI and blockchain. Blockchain data can be analyzed by AI to provide instantaneous insights into the patient's health. In turn, the blockchain can safeguard the data and offer accountability and openness.

One real-life example of AI and blockchain in healthcare is Medicalchain. This platform uses blockchain technology to store and share medical records securely, allowing patients to share their medical data with doctors and researchers while ensuring their privacy. The platform also uses AI to analyze medical data and develop personalized treatment plans.

Finance

One of the pioneers in blockchain and AI use is the financial sector. These two technologies working together provide a number of advantages, including improved efficiency, security, and transparency. We will look at several practical applications of blockchain and AI in the financial sector.

Let's first examine how AI may enhance finance. To find patterns and make forecasts, AI algorithms may examine enormous volumes of financial data, including client transactions, market trends, and economic indicators. This can aid financial firms in improving client satisfaction, lowering risks, and making smarter investment decisions

By offering round-the-clock assistance and individualized recommendations, AI-powered chatbots and virtual assistants can also enhance client relations. This shortens lines and improves the clientele experience.

Let's now investigate how blockchain can improve finance. With blockchain technology, financial data may be shared and stored in a secure and open manner. Transactions are recorded in a tamper-proof and decentralized ledger, lowering the risk of fraud and assuring openness and accountability.

A blockchain-based system, for instance, can enable peer-to-peer transactions without the need for middlemen like banks. This lowers expenses and speeds up transactions.

The finance sector may improve its efficiency and security by merging blockchain and AI. In order to detect fraud and lower risks, AI systems can examine data gathered from the blockchain in real-time. In turn, the blockchain can safeguard the data and offer accountability and openness.

One real-life example of AI and blockchain in finance is the partnership between IBM and Stellar. Stellar is a blockchain-based payment platform that uses AI algorithms to analyze transaction data and detect fraudulent activities. This enhances security and reduces risks, while also improving transaction speed and reducing costs.

Another example is the partnership between Ripple and Santander. Ripple is a blockchain-based payment platform that uses AI algorithms to provide real-time insights into currency fluctuations and market trends. This enables faster and more efficient cross-border payments, reducing transaction costs and enhancing customer experiences.

By automating tasks, providing real-time insights, and securing data, AI and blockchain can help financial institutions reduce costs, improve customer experiences, and ensure transparency and accountability.

Gaming

The gaming industry has experienced rapid expansion in recent years, and the use of blockchain and AI technologies has the potential to improve user experience even more. We will examine how AI and blockchain can be applied to gaming, along with some instances from the real world.

Let's start by discussing how AI can enhance games. More intelligent and difficult game foes that can adjust to the player's playing style can be made using AI algorithms. Players may have a more immersive and captivating experience as a result.

AI can also be applied to the creation of gaming environments, characters, and plotlines. This can improve the quality of the game while also reducing the amount of time and resources needed for game creation.

Let's now investigate how blockchain can improve gaming. Players can purchase, sell, and exchange virtual goods in-game economies built using blockchain technology. Additionally, tracking ownership and transactions of these virtual assets may be done securely and transparently using the blockchain.

Because of this, gamers may be able to cash in on their in-game accomplishments by trading virtual goods for real money. By guaranteeing that all transactions are documented and validated on the blockchain, blockchain can also aid in the prevention of fraud and cheating.

One real-life example of AI and blockchain in gaming is the game "CryptoKitties". CryptoKitties is a blockchain-based game that allows players to buy, sell, and breed virtual cats. The game uses AI algorithms to create unique virtual cats with different characteristics, such as fur color and pattern. Players can then trade these virtual cats using cryptocurrency.

Another example is the game "Gods Unchained". Gods Unchained is a blockchain-based trading card game that uses AI algorithms to create intelligent opponents that can adapt to the player's playing style. The game also uses blockchain technology to track ownership and transactions of virtual cards.

Although there are many more applications for fusing AI and Blockchain technologies, the ones in this article are the most prevalent and in use right now, so they were included.

Merits and Demerits of Using AI and Blockchain Together

As discussed extensively, the fusion of blockchain and AI can assist many different businesses in several ways. There are some disadvantages to take into account, though. Let's examine the benefits and drawbacks of combining blockchain and AI together.

Merits

Enhanced Data Security: One of the most important advantages of combining blockchain and AI is enhanced data security. Blockchain offers a decentralized, impenetrable ledger that guarantees data integrity. Moreover, real-time fraud and anomaly detection is facilitated by AI algorithms, which makes it simpler to stop data breaches.
Enhanced Efficiency: Several operations may be automated and optimized using AI algorithms, which increases their efficiency. Data may be shared and stored securely and transparently with the help of blockchain, making it more accessible and understandable.
Improved Decision-Making: By merging AI and blockchain, firms may access more precise and dependable data and make better judgments. Blockchain can guarantee the accuracy and transparency of the data while AI algorithms can evaluate vast amounts of data.
Cost Savings: By automating operations, removing the need for middlemen, and minimizing fraud and errors, AI and blockchain can help cut expenses.

Demerits

Complexity: AI and blockchain are both sophisticated technologies that call for specialized training. The integration of these technologies can be difficult and expensive.
Scalability: The scalability of blockchain technology might be slow and constrained. For smaller firms, using AI algorithms can be challenging because they can demand a lot of computational power and resources.
Lack of Regulation: Because AI and blockchain technology are still in their infancy, there are currently no rules or standards in place. For businesses, this may result in uncertainty and risk.

Despite the fact that blockchain technology offers transparent and secure data storage, privacy issues exist. The public visibility of personal data kept on the blockchain can worry both people and companies.

Blockchain and AI have the potential to revolutionize a number of businesses by enhancing data security, boosting productivity, and facilitating improved decision-making. The complexity, scalability, lack of regulation, and privacy issues related to these technologies must be taken into account, though. Businesses can decide if this strategy is best for them by carefully considering the benefits and drawbacks of combining AI and blockchain.

Future Ideas

Looking ahead, the integration of AI and Blockchain has the potential to transform many industries, such as agriculture, energy, and logistics. Some of my personal opinions on potential ideas for how AI and blockchain can be used together in the future are;

Decentralized Autonomous Organizations (DAOs): A DAO is a decentralized organization whose rules are stored on the blockchain as computer programs. DAOs can make autonomous decisions based on current facts and offer more efficient and effective governance by integrating AI algorithms.
Artificial intelligence and smart contracts: With a smart contract, the conditions of the agreement between the buyer and seller are directly encoded into lines of code, making it a self-executing contract. Smart contracts can become more effective and autonomous by including AI algorithms that enable automatic execution when specific criteria are satisfied.
Predictive analytics: Businesses can use predictive analytics to more accurately predict trends, behaviors, and outcomes by fusing blockchain data with AI algorithms. Businesses may be able to make wiser decisions as a result and acquire a competitive edge.
Tokenized AI Models: AI models that have been tokenized can be made available to anybody who wants to utilize them by being tokenized on the blockchain. This may make it possible for users to access AI models directly from developers in a decentralized AI ecosystem.
Autonomous Supply Chains: Businesses may develop autonomous systems that can control the full supply chain process from procurement to delivery by integrating AI and blockchain into supply networks. This can boost productivity, cut expenses, and stop fraud.

Conclusion

I am thrilled about the potential of AI and Blockchain to alter organizations and societies as a software developer and entrepreneur. Enhancing security, privacy, and decentralization are just a few advantages that can come from combining these two technologies. Although there are still some obstacles to be solved, this partnership has enormous promise, and there will likely be many more new applications and developments in the future. I am enthusiastic about the prospects these technologies bring for a better future as I continue to investigate them.

Writing better README.md files using GitHub flavoured markdown

Imam Abubakar — Fri, 02 Dec 2022 23:18:25 +0000

Introduction

GitHub flavoured markdown is a set of extensions to the standard markdown syntax that gives you some cool features to make your README.md files look great on GitHub. In this article, we'll look at some of the features that GitHub flavoured markdown has to offer and how you can use them in your own README.md files.

README.md Formatting

Headings

GitHub flavoured markdown supports two types of headings: setext and atx.

Setext headings are created by underlining the heading text with = for h1 headings and - for h2 headings. For example:

This is an H1
=============

This is an H2
-------------

Atx headings are created by surrounding the heading text with # characters. The number of # characters you use determines the heading level, with # being h1, ## being h2, ### being h3, and so on. For example:

# This is an H1

## This is an H2

### This is an H3

#### This is an H4

##### This is an H5

###### This is an H6

Lists

GitHub flavoured markdown supports both ordered and unordered lists.

Ordered lists are created by prefixing the list items with numbers followed by a period. For example:

First item
Second item
Third item

Unordered lists are created by prefixing the list items with -, +, or *. For example:
This

- First item
- Second item
+ Third item
* Fourth item

will create these:

First item
Second item
Third item
Fourth item

Images

Images are created by surrounding the image URL with ![](...). The text inside the [...] is used as the image alt text. For example:

![GitHub Logo](/images/logo.png)

Code Blocks

Code blocks are created by surrounding the code with blocks of 3 (`) . For example:

function foo() { console.log("foo"); }

Tables

Tables are created by using the | character to create columns and the - character to create rows. For example:

These:
| Column 1 | Column 2 | Column 3 | |----------|----------|----------| | Row 1 | Row 2 | Row 3 | | Row 4 | Row 5 | Row 6 |
will create these:

Column 1	Column 2	Column 3
Row 1	Row 2	Row 3
Row 4	Row 5	Row 6

Emoji

GitHub flavoured markdown supports emoji! 😄 To use emoji, simply type the emoji code 😄 and it will be replaced with the emoji image. For example, :smile: will be replaced with

![](https://github.githubassets.com/images/icons/emoji/unicode/1f604.png).

Conclusion

GitHub flavoured markdown is a great way to make your README.md files look great on GitHub. In this article, we've looked at some of the features that GitHub flavoured markdown has to offer and how you can use them in your own README.md files.

What is GameFi?

Imam Abubakar — Sun, 17 Jul 2022 22:52:47 +0000

Welcome to this article that gives you a breakdown of what GameFi is and what the trend is really about.

In this article, you will learn every basic knowledge required to know to understand what GameFi really is or as i prefer to call it, decentralized gaming. This article covers a simple breakdown, so it will be easier to understand even if you are not into blockchain.

Overview

GameFi, as the name suggests consists of two parts. The gaming part and the finance part.
The gaming part is simply a traditional gaming platform where you can have a character which you can use to compete against other characters in a series of gameplay or play against automated bots where you can earn in-game currency, and you can use this currency to upgrade your character, purchase weapons, costumes and other in-game items.
The finance part is also the blockchain part since it runs on the blockchain and it represents your in-game valuables, characters and the likes, which are commonly represented as ERC-721 Tokens (NFT) while other common game properties like costumes and weapons are mostly represented as ERC-1155 Tokens (NFT).

How does it work?

To put it more simply and concisely, GameFi refers to play-to-earn games that offer economic reward to players. Typically, players can earn cryptocurrency and NFT rewards by completing tasks, battling other players, and progressing through the different game levels. Although, some games also feature characters and items that can be used, which have no impact on the gameplay and earnings.

The GameFi ecosystem uses cryptocurrencies, non-fungible tokens (NFTs), and blockchain technology to create a virtual gaming environment.

Simple Breakdown of Blockchain Token standard in GameFi

Characters are represented as ERC-721 Tokens
The In-game currency is an ERC-20 Token
In-game items like costumes and weapons are represented as ERC-1155 Tokens

Onchain-to-Offchain analysis
The basic onboarding for this is that a game section will have a deposit and withdrawal gateway to enable movement of assets from onchain to offchain and vice-versa.

How to Earn?
First, as a player, you can go to the 'Exchanges' tab (might be different from game to game), buy gaming tokens and NFTs to be used in the game to upgrade characters, play the game, and try to win more tokens, which can then be exchanged for stable coins. Also, sales of game NFTs on the NFT marketplace with a much higher price can provide the player some profits.
Some games also let players generate passive income without playing the game, either through staking or by lending their gaming assets to other players.

Features of a standard GameFi project

Play-to-earn(P2E) model:
The Play-to-Earn gaming model is at the core of every GameFi project. Compared to traditional video games like 'Call of Duty' and 'God of War' that use a pay-to-play model that requires players to purchase licenses or recurring subscriptions, the P2E model offers players opportunities to make money and also have full control over their in-game assets.
Asset Ownership:
As explained above, players can monetize their in-game assets in many different ways since they have full verifiable ownership and control over them since they are minted (NFTs) on the blockchain.
Decentralized Finance Features:
Some GameFi projects provide DeFi services like staking, liquidity mining, and yield farming. The in-game crypto assets or NFTs help players earn rewards, unlock exclusive items, and climb to new levels. Utilizing this, a lot of interesting features can be added to the project and this can increase its user size depending on what features are available.

GameFi Projects

Below are some of the popular GameFi projects trending at the time of writing:

Alien Worlds

Alien Worlds is an NFT Metaverse where you can play with unique digital items (NFTs). It comes with an autonomous organization, Planet DAOs, where players can participate in weekly elections for council candidates, submit proposals on how to distribute the planetary treasury or run for planetary council. Built on Binance Smart Chain and WAX Blockchain, it also has a cross-chain bridge to move TLM between BSC, WAX, and Ethereum.

Splinterlands

Splinterlands is a collectible card game where players can win rewards from tournaments, ranked play, and quests. Built on WAX and HIVE blockchains. A HIVE cryptocurrency wallet is automatically generated for you upon registration on their website. It has cross-compatibility with other blockchains such as Ethereum, Tron, and WAX,

Farmers World

Farmers World is the first farming game to function on the NFTs platform. Pick for yourself suitable tools, exploit various resources, buy land to build enormous farms, and enjoy the fascinating experiences of a farmer working in Farmers World’s ecosystem. Built on the WAX blockchain.
Gameta

Gemeta is a Metaverse platform built on the Solana Blockchain with over 40,000 users at the time of writing, providing a series of products designed to help web2 users immigrate to web3.

Upland

Upland is a metaverse based on the real world that brings together the thrill of earning NFTs and digital property holding fiat value with the enjoyment of game exploration and meeting fellow players. Backed by the highly-sustainable EOS blockchain, Upland has been recognized as one of Fast Company’s Next Big Things in Tech due to the platform's community-based commerce where players and businesses define gaming, earning, and connecting. Available on iOS, Android, and browsers, Upland captures the potential of Web 3.0 technology where virtual properties based on real-world addresses and historic landmarks become gamified hubs of activity that mesh digital communities with the real world.

Axie Infinity

Axie Infinity is a Pokemon-inspired digital pet universe where players use their cute characters called Axies in various games. The Axie Infinity Universe highlights the benefits of blockchain technology through "Free to Play to Earn" gameplay and a player-owned economy.

BinaryX

Cyber Dragon is a Play to Earn game based on the Binance Smart Chain. This game is powered by the BinaryX team. Players can create characters, collect rare equipments and challenge dungeon. It has a dual-token economic system of BNX + Gold. BNX is Cyber Dragon's governance token. BNX token holders can participate in community governance and vote on major game decisions. Gold as a BEP-20 token, it is the main currency in the game. Gold can be used in most consumption scenarios in the game and can be obtained by mining by participating in daily work after recruiting heroes.

There are many more projects available and many more to come, and I personally am interested in the upcoming Norse-inspired GameFi project, RUNEWARS.

None of the GameFi projects mentioned is being promoted in anyway, they are simply for references.

How to play GameFi games(Getting started)

Register for a crypto wallet (Metamask, Binance, Argent, and so on depending on the blockchain the game runs on and the user's choice).
Connect your wallet to the game (Go to the official site of the game and authenticate your wallet to initiate the gameplay as a user).
Check the game requirements before actually playing. This is important so that you can know the earning potential and overall risks before playing.

Some valuable contents

The word 'GameFi' came into play during the Wuzhen World Blockchain Conference held in China, mentioned in a speech delivered by the developers of blockchain game publishing firm, MixMarvel in November 8, 2019.

Following a massive boom in 2021, the GameFi space is gradually expanding, with over 1500 GameFi projects currently listed in DappRadar, available on multiple blockchains including Ethereum, BNB Smart Chain (BSC), Polygon, Harmony, Solana, and others.

In coming years, it is certain that the space will continue to increase and lots of GameFi projects will be available, especially in developing countries. The best part of this is the way GameFi combines entertainment with financial incentives, and in a way, shapes the buildup of the MetaVerse, which is a topic I will be expanding on in future articles.

What are Decentralized Applications?

Imam Abubakar — Sun, 05 Jun 2022 19:53:26 +0000

I really felt like breaking down the idea behind how decentralized applications work because I felt it would help a lot of people. You might be starting out as a Web 3.0 developer and might have even built a few things in the Web 3.0 space, but do you really understand how these decentralized applications that you have developed work behind-the-scenes? Probably not right. If you are feeling it's a yes, I would still advise that you stick to this article to the very end because you never know what you might learn.

I know, at this point, some readers might be feeling lost in these words, probably because they are not even in the Web 3.0 space yet, or they may be planning to after reading this. Well, allow me the liberty of starting from the very beginning for you all. If you feel you already know enough, you might decide to scroll down to where it gets interesting. With that stated, let's move along.

What is Decentralization?

In blockchain, decentralization refers to the transfer of supervision, control, and decision-making away from a centralized association (individual, group, or company) to a dispersed network.

If you are new to Blockchain technology or Web 3.0, check out my article on Breaking into Web 3.0.

Following along, decentralization is essentially the core of the blockchain's existence, and that is why it has grown so much since its creation. For example, having a platform that is completely fraud-free and is safe to use for everyone as long as your personal credentials are secure. This kind of safe platform is what drives the integration of blockchain technology into our daily use of the internet, like finance and gaming, among others. And trust me, who doesn't like to feel a little more secure when it comes to financial transactions, right? Because of these protection benefits, every big company wants to have blockchain integrated into their systems in one way or another. You, as an end-user, also want that kind of integration because you want a platform that offers you more safety in whatever it is you do on the internet. For the benefit of both the companies and the end-users, blockchain is being integrated into applications, and this is what we refer to as a "decentralized application," or dApp, for short.

What is a Decentralized Application?

According to Investopedia, a decentralized application (dApp) is a digital application or program that exists and runs on a blockchain or peer-to-peer (P2P) network of computers instead of a single computer. A DApp (also called "dapp") is outside the purview and control of a single authority. DApps (Decentralized Applications), which are often built on the Ethereum platform, can be developed for a variety of purposes, including gaming, finance, and social media.

Standard web applications such as Facebook and Twitter run on computer systems owned and operated by an organization, giving them full authority over the app and its behavior. A site can have multiple users but the backend is controlled by a single organization. This type of application is not decentralized.

To avoid a disclaimer, let me clarify to you that all applications with blockchain technology integrated into them can be referred to as a decentralized application, but not all decentralized applications run on a blockchain network. Feeling confused right now? Let me clear that up for you. Decentralized applications do not necessarily need to run on top of a blockchain network. Tor, Popcorn Time, and BitMessage are examples of decentralized applications that run on a P2P network but not on a blockchain, which is a special kind of P2P network. understood right? Good, let's move along.For the sake of clarity, the focus here is on decentralized applications that run on blockchain networks.

Examples of decentralized applications

Lets consider some of these decentralized applications.

Augur

Augur is a decentralized prediction market Platform for Ethereum and EVM compatible chains. Originally founded in 2014, with its version 1 release in 2018. Augur allows users to create prediction markets on different topics including sports, economics, and world events.

OpenSea

It is the first and largest marketplace for Non-Fungible Tokens(NFTs) and Semi-Fungible Tokens(SFTs) built initially on Ethereum and later integrated with Polygon to reduce the cost of transaction fees users have to pay. Here, users can trade NFTs freely by opening their own marketplace.

PancakeSwap

PancakeSwap is the most-popular dApp on the market by a large order of magnitude. It’s a fork of the original DEX, Uniswap, but since it’s built on the BNB blockchain, this means reduction in fees for traders. The lower fees are the main reason why PancakeSwap caught so much traction and features such a massive user base. Most newly-launched cryptocurrencies first start trading on PancakeSwap as anyone can list their token on the exchange, provide liquidity, and create a market.

Splinterlands

Splinterlands is a collectible trading card game built on the Hive and WAX blockchains. The gameplay is comparative to traditional trading card games like Hearthstone. The main difference is that Splinterlands is blockchain-based, meaning in-game resources are tokenized and give full possession for players.

Aragon

This Ethereum Blockchain-based platform can be used to create and run decentralized organizations. Aragon is an open-source project that is managed by the Aragon Foundation. The project's goal is to eliminate the need for human commerce by allowing individuals to run entire businesses and organizations using Ethereum Blockchain.

These are a few amongst thousands of dApps that are available on the internet today. These dApps are based on separate blockchain use cases like gaming, cryptocurrency, dAO, decentralized finance and exchanges, and more. There are many more dApps you should probably check out on your own. You can check this out as well.

Architecture of a decentralized application

Decentralized Application Frontend

The frontend code, which is executed on the user side, looks like any other application. However, it contains a digital wallet which:

Contains a record of the user’s private and public keys for authentication
communicates with the blockchain in order to manage cryptographic keys and blockchain addresses
Triggers the backend (smart contracts) to be executed.

Decentralized Application Backend

The backend code (smart contract) which runs on the server side of the application has the following characteristics:

It is stored and executed on a blockchain.
It is open source.
performs the same function regardless of the execution environment

In the above image, take notice that the dApp is on an Ethereum blockchain, therefore, the smart contract will run on an Ethereum Virtual Machine, also called an EVM. Also, take note that there are other blockchains that are compatible with the EVM. For example, Binance Smart Chain, Avalanche, Polygon Chain, Fathom, Cardano, and Tron.

Pros & Cons

Below are some of the benefits of using decentralized applications:

User Privacy: Users of decentralized applications do not have to submit personally identifiable information to use them.
Trustlessness: Smart contracts are used in decentralized applications to complete transactions between two anonymous parties without relying on a central authority or middleman.
Innovation: The blockchain provides a space for the development of new dApps, allowing developers to focus their efforts on finding new and innovative uses for digital applications.

Like with every other thing, there are a few disadvantages that come with decentralized applications:

Decentralized applications are still in their early stages, experimental and subject to a variety of issues and unknowns.
The issue of a bad user interface is a thing. To persuade people to switch to dApps, developers will need to create an end-user experience and a level of performance that rivals that of well-known and established programs.
There is also the issue of making upgrades to existing applications. According to Ethereum, developers may find it difficult to make necessary updates to dApps because the data and code published to the blockchain are difficult to change.

With that stated, i guess the article will take a halt here. This might be beneficial to you in some ways and might also not be as useful as you hoped, but i want to believe that it has added to your knowledge of what Web 3.0 development is all about and that is the most important thing here. You most likely have an idea what decentralized applications are now. You might have noticed that I didn't include how you can build a dApp. Well, this is a simple breakdown article, make sure to always check back and most likely i have written an article on how to do that.

Don’t forget to share this article, you never know who might be interested in decentralized applications.
