Ethereum (ETH)
Ethereum is a global, open-source platform designed for decentralized applications (dapps). It aims to create a "world computer" that allows developers to build applications in a decentralized manner, where all states and data are distributed and publicly accessible. As a leading force in blockchain technology, Ethereum provides a robust infrastructure for a wide variety of applications, including tokens, non-fungible tokens (NFTs), decentralized finance apps, lending protocols, and decentralized exchanges.

The vision of Ethereum
The core vision of Ethereum is to decentralize the web by enabling developers to create applications that do not rely on centralized servers and data storage. This decentralization ensures that applications are more resilient to outages and censorship, and also provide users with greater control over their data and digital assets.
Smart contracts
One of the key innovations brought by Ethereum is the concept of smart contracts. Smart contracts are self-executing contracts with the terms of the agreement directly written into lines of code. They enable developers to program digital value, automating complex operations and transactions without the need for intermediaries. This has opened up possibilities for a wide range of applications, from simple token transfers to complex multi-party agreements.
The Ethereum ecosystem
Ethereum powers a diverse ecosystem of decentralized applications, each leveraging the blockchain's capabilities to offer unique services and solutions. Some notable examples include:
Decentralized finance (DeFi)
DeFi applications aim to recreate traditional financial systems such as lending, borrowing, and trading on the blockchain. By eliminating intermediaries, DeFi platforms provide users with more transparent and efficient financial services. These platforms often require collateral in the form of digital assets and use smart contracts to automate transactions and manage risk.
Non-fungible tokens (NFTs)
NFTs are unique digital assets that represent ownership of a specific item or piece of content, such as art, music, or virtual real estate. Built on Ethereum, NFTs use the blockchain to verify ownership and provenance, creating new opportunities for creators and collectors to monetize and trade digital assets.
Decentralized exchanges (DEXs)
Decentralized exchanges allow users to trade cryptocurrencies directly with one another without relying on a centralized authority. By using smart contracts and liquidity pools, DEXs enable peer-to-peer transactions, offering greater security and privacy compared to traditional exchanges.
Understanding gas and Ether
Ethereum's native currency, Ether (ETH), plays a crucial role in the network's operation. All transactions and smart contract executions on the Ethereum blockchain require a fee, known as Gas. Gas is a unit of measure that reflects the computational effort needed to perform an operation or execute a smart contract. More complex operations require more gas, and the gas fees are paid entirely in Ether.
Gas fees and network demand
The price of gas can fluctuate depending on network demand. When many users are transacting or executing smart contracts simultaneously, the demand for gas increases, which can lead to higher gas fees. This dynamic pricing mechanism ensures that the network remains functional and efficient, even during periods of high activity.
