Solidity

 

Introduction to Solidity

Solidity is a brand-new programming language created by Ethereum which is the second-largest market of cryptocurrency by capitalization, released in the year 2015 and led by Christian Reitwiessner. Some key features of solidity are listed below: 

• Solidity is a high-level programming language designed for implementing smart contracts.
• It is a statically typed object-oriented(contract-oriented) language.
• Solidity is highly influenced by Python, c++, and JavaScript which run on the Ethereum Virtual Machine(EVM).
• Solidity supports complex user-defined programming, libraries, and inheritance.
• Solidity is the primary language for blockchains running platforms.
• Solidity can be used to create contracts like voting, blind auctions, crowdfunding, multi-signature wallets, etc.

Ethereum

Ethereum is a decentralized open-source platform based on the blockchain domain, used to run smart contracts i.e. applications that execute the program exactly as it was programmed without the possibility of any fraud, interference from a third party, censorship, or downtime. It serves as a platform for nearly 2,60,000 different cryptocurrencies. Ether is a cryptocurrency generated by Ethereum miners, used to reward for the computations performed to secure the blockchain. 

Ethereum Virtual Machine(EVM) 

Ethereum Virtual Machine abbreviated as EVM is a runtime environment for executing smart contracts in ethereum. It focuses widely on providing security and execution of untrusted code using an international network of public nodes. EVM is specialized to prevent Denial-of-service attack and confirms that the program does not have any access to each other’s state, also ensures that the communication is established without any potential interference. 

Smart Contract

Smart contracts are high-level program codes that are compiled to EVM byte code and deployed to the ethereum blockchain for further execution. It allows us to perform credible transactions without any interference of the third party, these transactions are trackable and irreversible. Languages used to write smart contracts are Solidity (a language library with similarities to C and JavaScript), Serpent (similar to Python, but deprecated), LLL (a low-level Lisp-like language), and Mutan (Go-based, but deprecated).
