What is Ethereum and How Does It Work? Ethereum is a decentralized platform that enables developers to build and deploy smart contracts and decentralized applications (DApps). Unlike traditional centralized systems, Ethereum operates on a blockchain network, which is a distributed ledger maintained by a network of computers (nodes).
One of the key features of Ethereum is its ability to execute smart contracts. Smart contracts are self-executing contracts with predefined rules and conditions. For example, imagine a vending machine that automatically dispenses a product when a certain amount of money is inserted. Similarly, smart contracts execute transactions or perform actions when specific conditions are met, without the need for intermediaries.
Here’s a simple example: Let’s say you want to create a decentralized lottery on Ethereum. You can write a smart contract that collects funds from participants, randomly selects a winner, and automatically distributes the prize to the winner’s Ethereum address. Once deployed on the Ethereum blockchain, this smart contract operates autonomously, transparently, and securely, without the need for a central authority.
Brief History of Ethereum
Conception and Development (2013-2015): Ethereum was conceived in late 2013 by Vitalik Buterin, a programmer and cryptocurrency researcher. Buterin proposed Ethereum in a whitepaper as a decentralized platform for executing smart contracts. In early 2014, development began with Buterin and a team of co-founders, including Gavin Wood, Joseph Lubin, and others.
Ethereum ICO (2014): Ethereum conducted its Initial Coin Offering (ICO) in mid-2014, raising over $18 million by selling Ether (ETH) tokens. The ICO attracted significant attention and marked the beginning of Ethereum’s journey as a blockchain platform.
Launch of Ethereum Mainnet (2015): The Ethereum mainnet, also known as Frontier, was launched on July 30, 2015. This marked the official release of the Ethereum blockchain, allowing developers to deploy decentralized applications (DApps) and execute smart contracts on the network.
The DAO and Hard Fork (2016): In 2016, a decentralized autonomous organization (DAO) built on Ethereum called “The DAO” raised over $150 million in Ether. However, a vulnerability in The DAO’s code led to a significant exploit, resulting in the loss of funds. To mitigate the damage, the Ethereum community conducted a controversial hard fork, splitting the Ethereum blockchain into Ethereum (ETH) and Ethereum Classic (ETC).
Ethereum Improvement Proposals (EIPs): Since its inception, Ethereum has undergone several upgrades and improvements through Ethereum Improvement Proposals (EIPs). Notable upgrades include the transition from proof of work (PoW) to proof of stake (PoS) consensus mechanism, known as Ethereum 2.0, which is still underway.
Rise of Decentralized Finance (DeFi) and Non-Fungible Tokens (NFTs): In recent years, Ethereum has become the foundation for the explosive growth of decentralized finance (DeFi) applications and non-fungible tokens (NFTs). These innovative use cases have propelled Ethereum to become one of the most prominent blockchain platforms in the cryptocurrency ecosystem.
