💡 Info: This article originally appeared under the Finxter brand — in collaboration with NotSatoshi. Enjoy! In the previous posts, we developed simple smart contracts, deployed them using Remix or Truffle, and interacted with them using JSON-RPC interface providers such as using web3.py or web3.js. In this post, we shall take a closer examination into […]

This article originally appeared on the Finxter blog—our companion blog for learning programming languages. Finxter Blog: Common Consensus mechanisms in Blockchains We know what a blockchain is and its wide applications. Blockchain is a distributed computing technology involving multiple nodes distributed across geographies. The problem is to ensure that each node gets the exact copy

This article discusses details on how to interact with smart contracts on Ethereum using Truffle and Infura. We will use a simple smart contract such as a storage contract to deploy and then interact or test the smart contract. To set up Infura, you can refer to my previous article here Setting up Infura account.It

In this post, we get an insight into what Infura is and then set up an account with Infura. We will also see some internal operations of Infura and a few salient parameters in Infura settings. So let’s begin. Overview of Infura We have multiple Ethereum clients such as Parity, Geth, and many more that

In this post, we will see the usage of web3.py in transactions, such as sending Ether from source to destination addresses. It will also include a brief introduction on web3. More specifically, we will look at techniques to send a transaction using the web3.py library with the necessary examples for the Ethereum blockchain. The need

What Is Polygon? Previously Matic Network, Polygon functions as a framework designed to connect blockchain networks (i.e. interoperability). Polygon seeks to build upon Ethereum’s limitations (poor user experience, throughput, lack of governance). Their solution is a sidechain. Developers can tailor their needs and launch preset blockchain networks. This means that the creation of sovereign blockchains

dYdX is an open-sourced, decentralized exchange (DEX) built on the Ethereum blockchain. Users can lend, borrow, and bet using the margin trading protocol on the future prices of crypto assets. Tools you’d normally find in traditional finance markets will be brought to the forefront with dYdX. dYdX plans to take DeFi (decentralized finance) to the

The Need for Layer-2 Ethereum has a lot of things going for it. The blockchain has a rich and powerful ecosystem. There is no shortage of developers and dApps. The competitive advantage is tough to beat. There’s only one problem—scalability. Due to Ethereum’s rising popularity, more dApps and users continue to join in on the

In this article, we will cover the internal data structure of a blockchain (w.r.t Bitcoin). We delve into the blockchain organization and look at the contents of each block, forming the basis of the blockchain. As a novice to the blockchain, understanding blockchain internals assists a lot if one has the thirst to build the blockchain(cryptocurrency). If

You have fair theoretical know-how of what an Ethereum blockchain and dapps are. However, you have no idea how to proceed to get a practical hands-on, to start coding and experimenting. This blog post will explain the tools used to build dapps for the Ethereum blockchain. We will explore various tools available for blockchain, especially
