Why You Should Use Solidity for Blockchain Development

Solidity is a modern programming language used for implementing smart contracts on the Ethereum blockchain. It is an object-oriented language designed for the Ethereum Virtual Machine (EVM). 
This statically typed language supports advanced programming features such as inheritance and custom data types. Solidity can be used for various smart contracts, including voting, multi-signature wallets, and crowdfunding. Solidity developers regularly update the repository with new features and bug fixes. 
It is based on ECMAScript syntax, making it easy to understand and code. Hierarchical structures and C3 linearization are supported for multiple inheritance. Mapping is done using key-value data structures.  
Solidity can be used with crypto wallets like Mist and MetaMask. You can also use Truffle for developing and deploying high-level Solidity code. Such tools enable engineers to create decentralized applications (dApps) with minimal effort. 

What Are Smart Contracts and How Do They Work? 

Smart contracts are self-executing contracts that run on the blockchain. Once the blockchain confirms that the necessary transactions have occurred, smart contracts execute the predetermined conditions. They can be used for financial transactions, supply chain management, identity verification, and more. 
Most smart contracts use ERC20 or ERC721 tokens for issuance, but you can also create custom contracts that do not require a token before execution. 
Smart contracts use oracles to ensure that all external conditional requirements are met before processing transactions. An oracle acts as an intermediary between blockchain code and external data, allowing blockchain programs to interact with data stores outside their network. Oracles can be hardware or software. 
Although smart contracts are very powerful programs that automate the execution of agreements, they are still programs. This means they are heavily dependent on their underlying code. If the underlying code is faulty, the resulting contract will have issues. 

Solidity and Ethereum

Many blockchain engineers prefer Solidity because it works with Ethereum, the de facto blockchain protocol for smart contracts. Additionally, it allows for creating multifaceted applications with rich functionality, as Solidity is Turing-complete (i.e., it can perform any task given the right instructions, enough time, and computational power). 
Various methods such as setters, getters, and greetings can be used to interact with Ethereum-based smart contracts. After creating a contract, you need to link it to a crypto wallet and generate a smart contract wrapper. Then you can use the smart contract address to conduct transactions.   

What Do Solidity Developers Do? 

Solidity specialists design, develop, and deploy smart contracts on Ethereum. They take client requirements, break them down, and turn them into implementable functional use cases. They audit smart contracts and ensure their authenticity. 
Solidity developers also integrate Solidity code on various platforms and develop new features for existing blockchain projects. In addition, they automate business processes and handle platform security issues (fraud analysis, security scanning, etc.).

What Skills Are Required for Solidity Development?

Solidity is heavily influenced by languages like JavaScript, Python, and C++, so engineers working on Solidity should know at least one of them. Solidity engineers should also know standard programming principles such as DRY and KISS, as well as database management. Smart contracts often involve sensitive data and monetary transactions, so Solidity developers must understand cybersecurity. They should also be well-versed in network security and preventing common cyber attacks like XSS and DDoS. 
Solidity runs on the blockchain, so Solidity engineers must be knowledgeable about blockchain protocols and tokenization algorithms such as ERC721 and ERC20. Additionally, engineers with knowledge of decentralized finance (DeFi) infrastructure and dApps are preferred, as they are necessary for creating advanced blockchain contracts. 

Is Solidity Difficult to Learn? Is It Worth Learning in 2024?  

Solidity is a complex language based on Ethereum. Although you can develop many use cases with OOP concepts and ready-made snippets, you need to learn the basics of programming in languages like Python or JavaScript. Once you've mastered them, working with Solidity will be relatively straightforward. 
In recent years, blockchain has been rapidly gaining popularity across various industries. According to experts, the blockchain market will exceed $39 billion by 2025. And this figure will only grow after the adoption of Web 3.0.  
Web 3.0 is the third iteration of web development. It is a decentralized evolution of web technologies, popularly called the 'internet of the future.' It places a strong emphasis on decentralized application development and blockchain-based web design. With the ability to create (and implement) smart contracts on various platforms, Solidity can occupy an important place in Web 3.0 application development. 

What Should Beginners Know About Solidity Development? 

Anyone starting with Solidity should know that smart contracts are immutable (i.e., they cannot be changed after deployment). There is no room for error when creating such contracts because transactions cannot be undone. This also means that mistakes in creating such contracts can lead to legal and financial loopholes for clients. 
However, this immutability can be useful for establishing trust and determining the legitimacy of smart contracts. Once you sign a contract, you can be sure its protocols will not change unless the underlying code is changed, which requires authority from both signing parties. 
Beginners should also be mindful of loop and computation issues during development. Computations on Ethereum are expensive. Each computational step incurs gas costs, and Solidity contracts can require a large number of steps. These steps can also become targets for hackers, who might use them to create false DOS problems. Therefore, Solidity beginners should always keep loop and gas payment issues in mind when creating blockchain contracts.
