Solidity in Blockchain

Assalamualaikum

Greetings to you all!

Solidity is programming language which is utilized to write smart contracts at Ethereum blockchain.This is one of most essential tool for developers to build decentralized apps at Ethereum so let's talk about different aspects of solidify in detail.

Solidity introduction

Solidity is contract which is oriented, high level programming language which have major impact of C++, python and javascript.This is used for writing self executed contracts with blockchain technology contribution.This is particularly designed for easy in learning and usage that make it accessible for developers with variations in levels of experience.

Solidity was proposed first time in 2014 by a person named Gavin wood who is co founder of Ethereum blockchain.Solidity language in start was known as serpent but after that it was renamed to solidity.From the time of its inception solidity has undergone different updates and enhancements with latest versions of solidity.

Solidity features

Following are features of solidity;

There are contract oriented solidity which is designed particularly to write smart contracts.Turing complete is another solidity feature which is a complete language and it means that it may give solution of any computational problem.

There are statically typed another solidity feature which is helpful in catching bugs at complie time instead of runtime.Another solidity feature is oriented to object programming in which polymorphism may be taken as an example.

Solidity use cases

Following are solidity use cases;

Decentralized finance in solidity is useful for building decentralized finance apps like lending protocols and decentralized exchanges.Non fungible tokens in solidity is useful in creation and management of NFT which are used for representing unique digital tokens.

Gaming in solidity is useful in building blockchain based games which are used in offering decentralized and transparent gameplay.Supply chain management in solidity is useful in building supply chain management system which are used for providing transparency and accountability.

Solidity syntax

Solidity syntax is just like other programming languages.Now I am sharing simple solidity contract example with all of you guys

pragma solidity ^0.8.0;

contract SimpleContract {
    uint public count;

    constructor() public {
        count = 0;
    }

    function increment() public {
        count++;
    }
}

Solidity data types

Following are data types of solidity:;

First of all there are integers which may be written asuint and int for those integers which are unsigned and signed in a respective way.After that another data type includes booleans which may represented as bool for boolean values.

Strings may be shown asstring for string values.There is also one more solidity data type in which arrays is common and it may be represented as uint[] and string[] for integers and strings array in a respective way.At last mappings is another data type which may be written as mapping(address => uint) for mappings of addresses to integers.So above in address => uint ,uint is presentation of integers as I have discussed their presentation already.

Solidity functions

There are many functions of solidity which are useful in performing some particular tasks in a contract.Here I am presenting an example of a function which is incrementing a counter:

function increment() public {
    count++;
}

Solidity events

Solidity events are useful in notifying that external contracts or apps of alternations to contract state.I am here presenting example of an event which emitted when counter was incremented:-

event Incremented(uint count);

function increment() public {
    count++;
    emit Incremented(count);
}

Solidity security

Solidity security is something of major concern just like smart contracts which may be used for handling higher amounts of values.There are some practices for providing security of solidity contracts:-

• First of all there is a need of using secure coding practices so here there's a need of avoiding usage of insecure coding practices like usage oftx.origin rather thanmsg.sender.

• Secondly there's a need of testing it completely so it may be used for giving surety that they are safe and they functions as they are intended.There's a need of using security audits for vulnerability identification in your contracts.

Solidity tools and resources

Solidity developers use different tools and resources about which I am sharing below:-

• Truffle suite is a tool used to build,to test and to deploy solidity contracts.
• Web3.js is a javascript library for making interactions with Ethereum blockchain.
• Solidity documentation is official documentation that is used for providing a comprehensive data at versatile language and its features.

Conclusion

In conclusion I have discussed that solidity is powerful programming language to write smart contracts at Ethereum blockchain.Through its contract which is oriented towards design and turing complete functions, solidity is an important tool for developers to build decentralized apps.Through following practices and tools I have shared there can be more advanced security contracts made by developers.Hopefully everyone understood this topic very well.....…

Have a blessed day
