Ethereum is a blockchain-powered platform for building decentralized software and apps

Ethereum is a blockchain-powered operating system known for its cryptocurrency, ether

Ethereum's underlying blockchain allows developers to build decentralized applications (dApps) that leverage smart contracts to seamlessly run decentralized financial tools (crypto wallets, exchanges, marketplaces, and more), along with Web3 concepts like non-fungible tokens.

Top Ethereum dApps

Thousands of decentralized apps (dApps) run on Ethereum, including marketplaces, financial platforms, and social networks. Top apps include Uniswap, a decentralized exchange for buying and selling cryptocurrency, and OpenSea, the biggest marketplace for buying and selling non-fungible tokens (NFTs). New apps are built on Ethereum all the time, facilitating billions of dollars worth of transactions. Explore the biggest ones here.

Bitcoin and ethereum are decentralized cryptocurrencies with different functions

Bitcoin, launched in 2009, is primarily a digital currency and store of value with a fixed supply. Ethereum, introduced in 2015, enables smart contracts and decentralized apps, offering more flexibility.

Decentralized applications are blockchain-based and run without a central authority

These apps use smart contracts to automatically execute functions, ensuring security, transparency, and censorship resistance. Built on platforms like Ethereum, Solana, and Binance Smart Chain, DApps power DeFi, NFTs, gaming, and social media, offering users control over their data and assets.

Vitalik Buterin’s current thoughts on Ethereum

Vitalik Buterin isn’t just the founder of Ethereum—he’s also a blogger. In this blog post from late last year, Buterin discusses some of his favorite applications built on Ethereum: prediction markets like Polymarket, where users can bet crypto on the outcome of events like elections. Buterin argues that prediction markets also act as news sites for non-bettors, opening the floodgates for many different kinds of info-based apps on Ethereum. Read the post here.

The similarities and differences between bitcoin and ethereum

Ethereum is the second-largest cryptocurrency by market cap behind Bitcoin. Usually, that comparison just scratches the surface of the overall market cap. Instead, a visual pits the tokens up against each other on a per-token basis and shows how and why the Ethereum/bitcoin ratio has fluctuated over time.

Ethereum’s biggest risks and top criticisms

As it evolves, critics say Ethereum’s constant changes make the platform overly complex and fundamentally less secure. They also say the Ethereum Foundation and a handful of developers wield too much control over the crypto platform, and that gas fees are prohibitively expensive. Some criticisms are addressed in Ethereum’s roadmap, but others strike at the crypto platform’s core. Go deeper on why here.

The Ethereum Foundation’s latest report

The Ethereum Foundation is a nonprofit organization supporting Ethereum in several ways. These include providing grants to developers who want to build on the blockchain, and hosting events promoting crypto’s future, like Devcon. This annual report grants a peek into the nonprofit’s role in Ethereum's operations and the values it seeks to support through its work. The nonprofit’s frontline involvement is another differentiating factor between Ethereum and other cryptocurrencies.

What are smart contracts?

Smart contracts are potentially one of the most useful tools associated with blockchain, and they can enable the transfer of everything from Bitcoin and fiat currency to goods transported around the world. Here’s what they do and why they’re likely to gain traction.

Crypto exchanges are online platforms to buy, sell, and exchange cryptocurrencies

Crypto exchanges have grown alongside and fueled the boom in digital currencies. Popular exchanges like Coinbase, Kraken, and Binance each have separate features, fee structures, and more.

Ethereum Classic and the Ethereum hard fork

One year after its launch, Ethereum was forked into two blockchains as a workaround to return funds stolen in a major hack to users. To this day, Ethereum Classic operates separately from Ethereum, and the two blockchains have different goals. Because of this split, investors must be cautious and ensure they’re interacting with the correct blockchain. Funds can’t simply be transferred from one to the other. Learn more here.

How to stake Ethereum

Ethereum switched to a proof-of-stake method for validating transactions in recent years, and now investors can stake 32 ether to participate and earn rewards. Several ways to get involved in ether staking exist, with varying levels of income, difficulty, and impact. Some allow users to stake less than 32 ether by pooling funds with other users, while others require less advanced hardware. Read about the different staking methods here.

Learn about Web3 and how it differs from past versions of the internet

Web3 is the idea of a new, decentralized internet built on blockchain technology. It aims to shift control from centralized entities like big tech companies to users through distributed ledgers and smart contracts. Key components include cryptocurrencies, NFTs, and decentralized autonomous organizations (DAOs) that operate without a central authority. Web3 promises more user privacy, ownership, and control over data and digital assets.

What does the surge phase mean for Ethereum?

The Surge is the next major upgrade for Ethereum. It’s a process aiming to scale up Ethereum, letting it handle more transactions, more efficiently. A key part of this process involves “layer 2 rollups,” which bundle transactions in part of the blockchain to process them more quickly. The Surge is expected to improve Ethereum’s decentralization and lower gas fees. Learn more in this article.

DAI is a popular stablecoin backed by cryptocurrency rather than fiat currency
