In this paper, the coding concept will share an overview of the Solidity language.
Dapps, or Decentralized Applications, are applications built on the open-source. Peer-to-peer Ethereum Blockchain network that uses smart contracts and a front-end user interface to create a decentralized platform.
Developing a Dapp, like any other application, requires programming and executing code on the system. Solidity programming stands apart from other programming languages and is the programming language of choice on Ethereum.
Solidity is a new programming language developed by Ethereum, the second-largest cryptocurrency market by capitalization.
If you are interested in learning more about Solidity Programming and its concepts, then you are in the right place. This Solidity Programming tutorial will cover the various important components of Solidity Programming.

What is Solidity Programming
Solidity is a programming language that was specifically developed by the Ethereum Network team for the purpose of creating smart contracts on Blockchain platforms.
It is designed to provide a means of creating machine-level code that can be compiled on the Ethereum Virtual Machine (EVM).
One of the primary uses of Solidity is to create smart contracts that implement business logic and generate a chain of transaction records on the blockchain.
Smart contracts are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code.
Solidity is quite similar to other programming languages such as C and C++. It is relatively easy to learn and understand, with concepts and syntax that are familiar to many programmers.
For instance, the “main” function in C is equivalent to the “contract” in Solidity. Additionally, Solidity offers features such as variables, functions, classes, arithmetic operations, and string manipulation that are common in other programming languages.
Solidity Programming Evolution
Solidity is a programming language designed specifically for the creation of smart contracts on blockchain platforms.
Developed by the Ethereum Network team, it is used to write code that implements business logic and generates a chain of transaction records on the blockchain.
It is similar to C and C++ and is easy to learn and understand. Solidity is the primary language used on Ethereum and other private blockchains such as Monax’s Hyperledger Burrow.
Additionally, SWIFT has created a proof of concept that runs on Burrow using Solidity.
What are EVM and Smart Contracts?
EVM or Ethereum Virtual Machine
The Ethereum Virtual Machine (EVM) is a crucial component of the Ethereum network that enables the execution of smart contracts.
It acts as a secure and isolated environment for these contracts to run on, protecting them from external threats and ensuring their proper functioning.
The EVM utilizes a network of public nodes to validate and execute smart contracts, preventing malicious actors from carrying out Denial-of-Service attacks and ensuring the integrity of the contract’s code and data.
The EVM also ensures that contracts do not interfere with each other and provides a secure means for communication between them.
Smart Contracts
Smart contracts are self-executing code that can be written and deployed on a blockchain network, such as Ethereum. They allow for trustless, transparent and irreversible transactions between parties.
They are written in programming languages such as Solidity, Serpent, Mutan, and LLL and are compiled into the Ethereum Virtual Machine (EVM) for execution on the Ethereum blockchain.
Data Types of Solidity Programming
1. Boolean: The Boolean data type in Solidity returns the value ‘1’ if a certain condition is true and ‘0’ if it is false. This can be used in smart contract code to make decisions based on the status of a certain condition.
2. Integer: Solidity supports signed and unsigned integer values. This means that the numbers can be either positive or negative, or only positive. Additionally, Solidity supports runtime exceptions and the keywords ‘uint8’ and ‘uint256’.
3. String: In Solidity, strings can be denoted by single or double quotes. This allows for the creation of text-based data that can be used in smart contract code.
4. Modifier: Modifiers are used in Solidity to verify that a certain condition is rational before executing the code for a smart contract. This can be used to add an extra layer of security to the code and ensure that certain actions can only be taken under certain conditions.
5. Array: Solidity supports both single and multidimensional arrays, similar to other OOP languages. This allows for the creation of data structures that can store multiple values of the same data type.
6. Map: Solidity also allows the use of “Map” data structures which can be used to store values based on enums, operators, and hash values. This can be used to return values stored in specific storage places. This is a powerful feature as it allows for the creation of complex data structures that can be used to store and retrieve data in a specific way.
Solidity Programming Advantages
1. Solidity is specifically designed for building smart contracts on blockchain platforms, making it a perfect fit for Ethereum and other similar networks.
2. It has a syntax that is similar to C and C++, making it relatively easy to learn and understand for developers who are familiar with these languages.
3. The Ethereum Virtual Machine (EVM) provides a secure and efficient runtime environment for Solidity smart contracts, allowing for fast and reliable execution.
4. Solidity supports a wide range of data types, including Booleans, integers, strings, and arrays, making it a versatile choice for different types of smart contract applications.
5. The use of modifiers in Solidity programming allows developers to easily specify and enforce certain conditions before executing a contract, providing an additional level of security.
6. The Solidity programming language has a growing community and a wealth of resources available, making it easy for developers to learn and get support.
7. The use of smart contracts can eliminate the need for intermediaries, reducing costs and increasing efficiency in various industries.
