What Is Solidity? What Are Its Use Cases?

Solidity is a high-level and contract-oriented language used for writing smart contracts. Developed by the core contributors of the Ethereum Blockchain Platform, it is used for designing and implementing smart contracts within the Ethereum Virtual Machine and other blockchain development platforms.

Using Solidity, developers can write applications that require self-enforcing business logic added in smart contracts. Since solidity is designed around the JavaScript syntax, it is easier for web developers to understand and implement it.

In contrast to other Ethereum Virtual Machine-based languages, Solidity includes the following functionalities:

• Supports multiple inheritances with C3 linearization.
• Support of state objects or variables, data types, and many more programming functions.
• Complex member variables for contracts containing structs and arbitrarily hierarchical mappings.
• Application Binary Interface facilitates several type-safe functions within a single contract.

Many blockchain platforms including Ethereum, Tendermint, Ethereum Classic, Counterparty, and ErisDB support Solidity.

Solidity Development supports the following data types:

• Integers: Solidity can support both unsigned and signed integer domains. For example, keywords like “uint256” can be used for allocating sizes of 256 bits and it also supports runtime exceptions.
• Booleans: The datatype boolean returns the value “0” as false and “1” as true, depending on the accuracy of a condition. The output is usually generated as a boolean value when the logical operators are used.
• Modifiers: Modifiers are used to identify the consistency of the conditions before the smart contract’s code is executed.
• String Literals: String literals can be either represented with double or single quotes.

Besides that, Solidity offers enums, operators, arrays and hash values to form a data structure termed as “mappings,” used for returning values linked with storage locations. As its syntax is same as that of any generic programming language, it can support both single and multi-dimensional arrays.

Tools that can be used by Solidity Developers for building Solidity based smart contracts:

• Solgraph: It is used for generating a DOT graph which visualizes function control flow of the Solidity contract and states security vulnerabilities.
• Solidity REPL: Solidity REPL is used for writing command line codes on Solidity Console.
• EVM Lab: It is a rich tool package that comes with an ability to interact with Ethereum Virtual Machine (EVM). It includes Etherchain API, trace-viewer and a VM.
• Evmdis: Evmdis stands for EVM Disassembler that can perform static analysis on the bytecode to offer a higher level of abstraction as compared to raw EVM operations.

Use Cases of Solidity Development

Voting

Currently, voting deals with numerous issues including manipulation of data, fake voters, alteration in voting machines and booth capturing. Solidity smart contacts can be created and deployed to make the voting process transparent and streamlined.

Blind Auctions

In an open auction, individuals can view each other’s bid which leads to disputes and frauds. Using Solidity Smart Contracts, the blind auction can be designed where users cannot see what someone bid until it ends.

Crowdfunding

Crowdfunding done via smart contracts can solve issues like the commission of a third party and management of data. Solidity smart contracts for crowdfunding do not require centralized systems to build trust, thereby reducing additional costs.

Whether you are looking out to deploy Solidity smart contracts or build a blockchain app using Solidity language, ensure to hire the team of experienced Solidity Developers who understand the concepts of solidity and have worked on the blockchain technology.
