Solidity & Ethereum in React (Next JS): The Complete Guide

What is Ethereum?

Ethereum is a technology that lets you send cryptocurrency to anyone, but in the first place It also powers applications that everyone can use, and no one can takedown. It’s the world’s programmable blockchain.

Ethereum builds on Bitcoin’s innovation, with some big differences.

Both let you use digital money without payment providers or banks. But Ethereum is programmable, so you can also use it for many different digital assets – even Bitcoin!

This also means Ethereum is for more than payments. It’s a marketplace of financial services, games, and apps that can’t steal your data or censor you. It’s the Future.

What is Solidity?

Solidity is an object–oriented, high–level language for implementing smart contracts. Smart contracts are programs that govern the behavior of accounts within the Ethereum state.

Solidity is a curly–bracket language. It is influenced by C++, Python, and JavaScript, and is designed to target the Ethereum Virtual Machine (EVM). You can find more details about which languages Solidity has been inspired by in the language influences section.

Solidity is statically typed, supports inheritance, libraries, and complex user–defined types, among other features.

With Solidity, you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi–signature wallets.
