Contracts in Ethereum using Solidity

November 25, 2021November 25, 2021Functional Programming, RustBlockchain, ethereum, Ethereum Setup, Ethereum Virtual Machine, Solidity

Reading Time: 2 minutes The Contracts in the sense of Solidity is a collection of code and data. That resides at a specific address on the Ethereum blockchain. Contracts in Solidity are similar to classes in object-oriented languages. They contain persistent data in state variables, and functions that can modify these variables. Creating Contracts Contracts can be create from outside via Ethereum transactions or from within Solidity contracts. Lets Continue Reading

Error handling in Solidity is very useful

November 25, 2021November 25, 2021RustError Handling, ethereum, panic, Rust, Rust programming language, Smart Contracts, Solidity

Reading Time: 3 minutes Hello guys, here is another blog on Solidity. Check out my previous blog on Value types in Solidity. In this blog, we will see how to do error handling in Solidity. Solidity uses state-reverting exceptions to handle errors. Such an exception undoes all changes made to the state in the current call and all its sub-calls and reports the error to the caller. When exceptions Continue Reading

Value Types In Solidity

November 1, 2021November 1, 2021Functional Programming, RustBlockchain, ethereum, Rust, Rust programming language, Smart Contracts, Solidity, value type

Reading Time: 3 minutes Solidity is an object-oriented, high-level language for creating smart contracts. Smart contracts are programs that decide the behaviour of accounts within the Ethereum state. Solidity is a statically typed language. It supports inheritance, libraries and complex user-defined types among other features. With Solidity, you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi-signature wallets. There are various data types in solidity Continue Reading

Why Solidity is used to Develop Smart Contracts?

October 7, 2021October 7, 2021Rustethereum, EVM, Solidity

Reading Time: 3 minutes Solidity was first proposed and developed in year 2014 by Gavin Woodand since then it has come a long way. Then Ethereum’s Solidity team led by Christian Reitwiessner developed it later. It is a high-level , object-oriented language used for implementing smart contracts. A smart contract is a self-executing contract. It has the terms of the agreement between buyer and seller. The code and the agreements Continue Reading

Do you know Ethereum, Smart contracts with Solidity?

August 21, 2021August 21, 2021Blockchain, Tech BlogsBlockchain, ethereum, Ethereum Virtual Machine, Smart Contracts, Solidity

Reading Time: 2 minutes Solidity is an object-oriented programming language for writing smart contracts on various blockchain platforms, most notably Ethereum. Ethereum Ethereum is an open-source, blockchain-based software platform. It has its own cryptocurrency called Ether. It enables the creation of smart contracts and decentralized applications, known as dapps. In addition, Ethereum is also a programming language that is executed on EVM. In simple words, Ethereum is “codify, decentralize, secure, and trade Continue Reading

Evolution of Ethereum followed by Bitcoin

Reading Time: 4 minutes Decentralised currency, digital currency, and peer-to-peer money all refer to bank-free methods of transferring wealth or ownership of any other commodity without needing a third party such as Banks. Bitcoin: Bitcoin is a consensus network that enables a new payment system and completely digital money. It is the first decentralized peer-to-peer payment network. From a user perspective, Bitcoin is pretty much like cash for the Continue Reading

Introducing Infura: Connecting DApps with Ethereum Network without setting up Ethereum Nodes

Reading Time: 3 minutes If you’ve been working on Decentralized applications based on Ethereum, you might have come across setting up the Local Ethereum Node or your own private Ethereum node to test your application. In my case, Setting up Ethereum nodes and connecting dApps with it has been a problem for me for the following reasons: If I use any of the Ethereum clients (geth or parity) Continue Reading

Understanding Different kinds of Ethereum Networks

Reading Time: 3 minutes After gulping a lot about the “disrupting” things related to Blockchain technology, I was very intrigued to quickly set up a development environment with whatever is free and useful on the Internet for developing a kick-ass DApp (I am Joking, Just trying “Hello, World!” 😉 I came to learn that “Ethereum” is the most matured protocol around blockchain. Before I proceed further with tools available Continue Reading

Getting started with Ethereum

Reading Time: 2 minutes What is Ethereum? Ethereum is an open-source blockchain platform that lets anyone build and use decentralized applications that run on blockchain technology. It is an open-source project created by Vitalik Buterin. How is it different from Bitcoin? Bitcoin is not capable of performing calculations that didn’t fit into his limited scripting language. Satoshi Nakamoto, the creator of bitcoin, did not design it to send anything Continue Reading
