Solidity Meaning

Jun 18, 2023 | Updated Jul 19, 2023
Solidity is a high-level, object-oriented programming language created for designing and implementing smart contracts.

What Is Solidity Programming Language?

Decentralized applications (DApps) are open-source applications or programs that are mostly developed on Ethereum’s network. Like any normal app, DApps developers use a programming language to build their apps. Solidity is one of the programming languages of choice in this case.

DApps use self-executing code or smart contracts to automate complex functions. Solidity is a contract-oriented programming language designed by the Ethereum Network team for implementing smart contracts. It draws inspiration from programming languages like C++, Python, and JavaScript, and interacts with the Ethereum Virtual Machine.

Here are the three main characteristics of Solidity:

  • Statically-typed: Solidity prevents mistakes, such as syntax and type errors, by verifying that every variable in the source code has a data type before it is executed to ensure that the application operates smoothly. 
  • Contract-oriented: The programming language is designed to create smart contracts, which are self-executing contracts containing terms of agreement written into lines of code. These contracts can be used to create decentralized applications (DApps) and execute transactions on the Ethereum network.
  • Object-oriented: Solidity uses objects (data structure or self-contained units of code) to present data and their behavior to allow developers to organize code in a structured and modular way.

Advantages of Solidity Programming Language

Solidity provides a number of advantages for DApps. For example, it:

  • Enables flexibility by allowing developers to create custom data structures, functions, and complex smart contracts.
  • Provides an interface, known as Application Binary Interface (ABI), that allows type safety to signal that there’s an error whenever there’s a mismatch in the data type of a variable. ABI is a set of rules and specifications that define how a smart contract can interact with other smart contracts.
  • Translates user-oriented requirements and specifications into a language that can be understood by machines.

What Are Its Drawbacks?

  • The language is vulnerable to reentrancy attacks, which occur when a contract allows a malicious user to repeatedly call a function in such a way that the contract’s state is exploited.
  • Blockchain’s immutable nature ensures that a smart contract, once deployed, cannot be modified or removed. Because of this, it’s crucial to make sure that every single line of code is flawless to prevent the risk of exploitation or hacking.
  • Solidity has arithmetic precision issues, where the language does not support fixed or floating-point values.

Gwei

In Ethereum, Gwei serves as a standardized unit that quantifies transaction costs, gas fees, and computational resources for executing transactions.
