Let’s start our journey into the exciting world of Ethereum!

What is Ethereum?

Ethereum is one of the most influential blockchain technologies to emerge since Bitcoin. Invented in 2015 by VitalikButerin, Ethereum introduced the revolutionary concept of decentralized applications (Dapps) through its innovation of smart contracts. Currently, Ethereum has a market capitalization of over $250 billion with over $10 billion in daily transaction volume according to CoinMarketCap. It has inspired a whole new “Ethereum killers” sector aiming to compete with its success. So what exactly is Ethereum and how does it differ from earlier blockchains? In simple terms, Ethereum is an open blockchain network that allows developers to build and deploy decentralized applications. Some key things to know:

  • Ethereum was launched in 2015 by VitalikButerin and is considered the second major cryptocurrency platform after Bitcoin.
  • Like Bitcoin, Ethereum uses a blockchain and cryptocurrency called Ether (ETH) that can be exchanged for other currencies.
  • However, Ethereum’s real innovation is its ability to support smart contracts using its Ethereum Virtual Machine (EVM).
  • Smart contracts are programs stored on the blockchain that run when predetermined conditions are met. They typically automate the execution of an agreement so that all participants can be immediately certain of the outcome, without any intermediary’s involvement or time loss.
  • This allows developers to create applications that have reliable rules and are resistant to domestic interference. Smart contracts are helping give birth to entirely new kinds of digital agreements.
  • Ethereum’s smart contracts set it apart from earlier blockchains like Bitcoin, enabling the creation of decentralized applications (DApps) that run on its blockchain.

So in summary, while Bitcoin introduced the world to blockchain and cryptocurrencies, Ethereum took it a step further by facilitating decentralized applications through its revolutionary smart contract functionality. This programmable blockchain opens up massive opportunities across many industries.

How Does Ethereum Work?

For something with such potential to reshape entire industries, Ethereum’s inner workings can seem complex. However, understanding a few key components is critical to grasping both its present capabilities and ambitious long-term technical roadmap. At its core, Ethereum relies on an Ethereum Virtual Machine (EVM) that runs on a distributed worldwide network of thousands of computers. Additionally, Ethereum uses a “proof-of-work” consensus model secured by miners, as well as its cryptocurrency called Ether that powers the network. Let’s break down these interacting elements that collectively form the foundation of an entirely new decentralized computing paradigm.To truly understand Ethereum’s potential, it helps to grasp the basics of how it operates at a technical level:

The Ethereum Virtual Machine (EVM)

  • The Ethereum Virtual Machine (EVM) acts as a global computer for running decentralized applications and smart contracts.
  • All Ethereum nodes run the same EVM code, allowing them to reach network consensus and process transactions simultaneously across the globe.
  • Developers write smart contracts using Ethereum-supported programming languages that get compiled into EVM bytecode to be deployed on the blockchain.

Mining and Consensus

  • Like Bitcoin, Ethereum uses a “proof-of-work” consensus model where miners use computing power to validate transactions and secure the network.
  • Miners are incentivized by being rewarded with Ether for processing transactions and adding new blocks to the blockchain.
  • As more miners join, it becomes increasingly difficult to mine new Ether, keeping the cryptocurrency scarce like gold.

Ether (ETH)

  • Ether (ETH) is the cryptocurrency or “fuel” that powers the Ethereum economy. It allows users to pay transaction fees.
  • ETH can be used as a currency for paying for goods and services, but its primary function is to allow users to pay for computational services on the Ethereum network like running smart contracts and apps.

So in summary, the EVM acts as a virtual computer, miners secure the network via proof-of-work, and Ether is the currency that powers smart contracts and decentralized applications on the Ethereum blockchain. This innovation unlocks immense possibilities compared to earlier cryptocurrency platforms.

Real-World Uses of Ethereum Today

While still in the early days eight years after launching, Ethereum is already demonstrating tangible, real-world applications that are improving people’s lives and opening new financial opportunities around the world. From enabling billions of dollars in global peer-to-peer cryptocurrency trading to representing digital art worth millions, Ethereum’s use cases span a diverse range of industries. In this section, we’ll explore several examples including decentralized finance (DeFi), non-fungible tokens (NFTs), blockchain gaming, and supply chain solutions to see how Ethereum is being applied today and the early traction it is gaining. While still in its early days, Ethereum has already inspired many exciting use cases across industries from finance to gaming. Here are a few examples:

Decentralized Finance (DeFi)

  • Decentralized lending protocols like MakerDAO and Aave allow users to borrow and earn interest on cryptocurrency deposits without middlemen.
  • Decentralized exchanges like Uniswap facilitate peer-to-peer cryptocurrency trading without centralized authorities.
  • prediction markets like Augur enable event betting via smart contracts instead of centralized bookmakers.

Non-Fungible Tokens (NFTs)

  • NFTs represent unique digital assets like digital art, collectibles, domain names, and more. Popular marketplaces include OpenSea and Rarible.
  • NFTs saw a boom in 2021 with record sales of digital art and celebrities like Grimes and Lindsay Lohan entering the space.


  • Blockchain games like Axie Infinity and Gods Unchained use NFTs to represent in-game assets that players truly own and can exchange or sell.
  • Pay-to-earn games allow players to earn money simply by playing and accomplishing tasks within immersive virtual worlds.

Supply Chain Management

  • Platforms like VeChain and Walmart China utilize smart contracts to transparently track product inventory, quality certifications, and shipments across global supply chains.

So as you can see, Ethereum is already enabling fascinating new sectors from finance to art to gaming. But its potential has barely been tapped – stay tuned for what innovative apps developers build next!
