How to build simulated blockchain realities (and rule that world) — [Abstract] GM. You wake up in the morning feeling very confident about your progress yesterday. Now you’re about to begin working on your Solidity smart contract. “Oh, this shouldn’t be so difficult; it’s just Solidity after all.” And indeed, it’s just Solidity after all. However, you’re now on your first…

This tutorial shows how to start a local Ethereum virtual machine (EVM) in Rust, query balance, and make simple transactions. The source code is available on Github. Setup requirements Before writing any code, we need to make sure we have some required tools installed, specifically Rust and Ganache. Rust Install Rust by following…

How it’s often useful to learn things no one asks you to — They’re used to structure Blockchains, which is why you might have heard of them, but also you might not know that Git uses Merkle Trees to store commits and compare diffs between files. In the corporate world, aka at work, the conceptual stuff tends to take a back seat. I’m…

Transaction receipt contains transaction outcomes (status and logs) and are organised in a trie structure. The receipt data resides in the state database and the root hash is stored in the block header. What information does the receipt trie contain? Who stands to benefit? Let’s dig deeper into those questions.

The Ethereum Virtual Machine (EVM) traces provide detailed run time data for each step of the transaction, including information such as gas used, result, error values, and so on. EVM traces, unlike state and transactions, are not part of the blockchain and do not have to be persisted on nodes. …

This is Part 4 of the “Let’s play EVM Puzzles” series, where I will explain how to solve each puzzle challenge. EVM Puzzles is a project developed by Franco Victorio (@fvictorio_nan) that is a perfect fit if you are in the process of learning how the Ethereum EVM works, and…

The Ethereum blockchain is very often referred to as “the global computer” as opposed to the Bitcoin blockchain which is commonly referred to as a “ the distributed ledger”. The main difference between these two well known blockchains is that Ethererum offers the possibility to deploy smart contracts which are…

There has been a lot of focus on layer-2 scaling solutions recently and it would be fair to say that 2022 will be the year of layer-2 scaling solutions. …

Have you ever wondered how the random 20 byte of address is generated every time you deploy a smart contract. Let us understand the process in brief by solving the challenge. We already know that the external address we see in our metamask wallet is the hashed value of our…

In the recent past, due to the launch of various defi applications on ethereum, the transaction cost has sky-rocketed. They are in the range of anything between $20-$50 now. Also, the transactions per second(tps) are also limited to 15–20 due to the use of Proof of Work as a consensus…

In-depth Analysis of Ethereum, Solana, Arbitrum, Optimism, Terra, Avalanche, and Fantom — Hello 👋🏻 🤓 I’m Miley. Panassaya L. I’m on a mission to learn and share as much as I can, with the hope that it’ll make our world just a bit better to live in. Let’s dive in! Key Takeaways Due to high demand and deflationary including burning gas more than emitting, it leads to extremely high gas fee…

In this series of posts I am going to present some code snippets in EVM Assembly and to explain how they work The reasons for this series post are the following Even though the security assessment of a project can probably be done remaining at the Solidity level, being able…

A complete overview of the Ethereum Yellow Paper, explained in an understandable way. — There are lots of different descriptions of Ethereum floating around on the internet. It’s a world computer, a game-changing technology, and the foundation for our digital future. These descriptions sound nice, but they don’t help us understand what Ethereum is, much less how it works. That’s where this post comes…

Q. What does EPNS do? Ethereum Push Notification Service (EPNS) is a platform-agnostic, decentralized notification protocol for Ethereum-based Web 3.0 applications. It enables users to receive notifications for on-chain or off-chain activity. EPNS allows Web3 actors (users, dapps, service providers) to create notifications that are triggered if and when a smart contract reaches certain conditions…

Ethereum Node Series IV — Let’s use python to create a script that calculates/audits the Etehreum difficulty! — This article will create and run a script that will audit and calculate the “total difficulty” in the Ethereum blockchain. This is super useful and fun, trust me! 😇 To be able to follow along, I’m assuming that you have already the following: An Ethereum node running on Ubuntu. Check…
