In this article, I will explain how to use mappings inside structs in Solidity. This guide will explain what are mappings in Solidity and how to use them structs. We will also learn what structs are in the world of Solidity. Let us get started with our guide right away. What are Mappings in Solidity? […]

In this article, I will explain how to solve transaction errors in Solidity. This guide aims to provide examples of how to solve transaction errors in Solidity. So, let us get this guide started. The Transaction Error in Solidity A transaction error is usually a result when there is an error with a function marked

In this tutorial, I will teach you how to perform error testing for your smart contract in Solidity. Error testing is a crucial aspect of development especially when it comes to blockchain development. Unlike development using other technologies, blockchain technology charges a fee to modify data on the smart contract. This is done to ensure

In this tutorial, I will discuss how to compile using Solc 0.5 in Solidity and above. Staying up to date with the latest syntax, code, methods, and techniques can be quite challenging when it comes to beginners in a programming language. Moreover, it is not so easy to be a beginner when it comes to

How to generate a random number in Solidity – is the question that brought you here today. Fortunately, you are at the right place! Since Solidity, Blockchain, Ethereum, and all other things related to these are relatively new for learners, it becomes difficult to understand what is going on sometimes and why. The Solidity programming

Today I am discussing the blockchain consensus algorithms we’ve been hearing about for quite a long time now. Blockchain technology is widely known for its distributed decentralized network structure that gives immutability and high security to data. This data lives in a block on the blockchain network without a central authority validating and verifying transactions

In this piece, I am telling you how is blockchain disrupting healthcare; a crucial thing to consider. Unquestionably, blockchain has solved and helped overcome major obstacles in the health sector such as providing drug traceability, secured and safeguarded confidential patient and hospital data, and reduced the exploitation of healthcare customers to a huge extent.  However,

Discussions on the blockchain are getting pretty cool. Today, I am telling you a bit about enterprise blockchains. Ever heard of it? Well, now you have! With the world getting better each day, at least technologically, there has been a mushrooming demand for even better security systems. Waking up in 2021, we see blockchain becoming

Most of you who read about blockchains might know they are different types of blockchains. Federated Blockchains are what we are discussing today. So, basically, there are 4 types of blockchains: private, public, hybrid, and federated blockchains. Blockchain technology has been since 2009 now which is obviously more than a decade. The technology has seen

We’re going to discuss Hybrid Blockchains, today. A hybrid of something usually refers to a mix of two or more things. Ever heard of a hybrid of a blockchain? Well, this type is the best of both worlds. Let us know how! The blockchain revolution is drastically and uniquely transforming the modern world. It is
