License Defintion
It is used to specify the license version under which the code will be distributed (made available to everyone). Every license has their own set of protocols for right to use, code modification, copy writing guidelines etc. Solidity has some of the popular license under : SPDX (Software Package Data Exchange), Apache License, MIT License, GPL & LGPL etc.
Example:
// SPDX-License-Identifier: GPL-3.0
Explanation:
The above code defines that the given source code will be licensed upon the GPL (General Public License) version 3.0 which gives the user the right to use, modify, study and distribute as well.
Unlock the Power of Solidity: Exploring the Essential Keywords for Smart Contract Development
Solidity is a smart contract programming language built solely to develop smart contracts that can be deployed on blockchains. C++ and JavaScript inspired it, an Object Oriented and High-Level language (HLL), that helps developers define the behaviour and rules for a Decentralized Application (Dapp). Smart contract facilitates autonomous, secure, and efficient transaction execution on the blockchain without needing any intermediary (self-executable) and solidity provides the base framework for achieving the same.
It is essential to understand the common keywords used in solidity to solidify your core understanding of the language so in this article, we’ll pin down some prominent keywords that help us develop these smart contracts by embracing the true power of solidity language.
