Top 11 Courses to Learn Solidity Online


Solidity is a contract-based, high-level programming language used for smart contracts. Christian Reitwiessner and Alex Beregszaszi, alongside former Ethereum contributors, developed Solidity programming language to implement smart contracts across blockchain platforms.

Solidity is influenced by top programming languages such as C++, Python, and JavaScript designed to develop smart contracts running on Ethereum. In general, solidity programming is statically typed and supports inheritance and libraries with syntax similar to JavaScript. Using Solidity allows verification and enforcement constraints at compilation instead of run-time.

The programs that are compiled using Solidity are intended to run on Ethereum virtual machines. The career prospects as a Solidity developer are witnessing gaining traction as they can cater to a wide range of industries such as blockchain, cryptocurrency, healthcare, retail, e-commerce, tourism, and travel and finance. Therefore, job seekers and enthusiasts need to be well-equipped with a Solidity skill set and delve into an exciting and future-proof career.
