What is Solidity?

Solidity is the object-oriented, high-level programming language for implementing smart contracts. Solidity was developed by Christian Reitwiessner, Alex Beregszaszi, and other former Ethereum core contributors.?Solidity is highly influenced by C++, Python, and JavaScript and has been designed to target the Ethereum Virtual Machine (EVM).

It's used?to create smart contracts that implement business logic and generate a chain of transaction records in the blockchain system.

What is Ethereum?

Ethereum is a decentralized ie. blockchain platform that runs smart contracts i.e. applications that run exactly as programmed without any possibility of downtime, censorship, fraud, or third-party interference

The Ethereum Virtual Machine (EVM)

The Ethereum Virtual Machine, also known as EVM, is the runtime environment for smart contracts in Ethereum. The Ethereum Virtual Machine focuses on providing security and executing untrusted code by computers all over the world.

The EVM specialised in preventing Denial-of-service attacks and ensures that programs do not have access to each other's state, ensuring communication can be established without any potential interference.

The Ethereum Virtual Machine has been designed to serve as a runtime environment for smart contracts based on Ethereum.

What is Smart Contract?

A smart contract is a computer program or a transaction protocol that is intended to automatically execute, control, or document legally relevant events and actions according to the terms of a contract or an agreement.?

Data Types of Solidity Programming

It supports all the common?data types?seen in other OOP languages, such as,

• Boolean - The Boolean data type returns ‘1' when the condition is true and ‘0' when it is false.
• Integer - You can sign or unsign integer values in Solidity. It also supports runtime exceptions and the ‘uint8' and ‘uint256' keywords.
• String - Single or double quotes can denote a string.
• Modifier - Before executing the code for a smart contract, a modifier often verifies that any condition is rational.
• Array - The syntax of Solidity programming is like that of other OOP languages, and it supports both single and multidimensional arrays.

Apart from that, Solidity programming allows you to "Map" data structures with enums, operators, and hash values to return values stored in specific storage places.

Advantages of Solidity Programming

Apart from the primary functionality of Solidity Programming, there are many other features provided by Solidity programming that cause it to have an edge over other Ethereum-based languages.

• Apart from fundamental data types, Solidity programming also allows complex data types and member variables.
• It provides an Application Binary Interface (ABI) to enable type safety. If the compiler discovers a data type mismatch for any variable, the ABI generates an error.
• It refers to the ‘Natural Language Specification,' which is used to turn user-centric specifications into language that machines can understand.
