What is Ethereum?

Ethereum is a decentralized, open-source blockchain platform that enables developers to build and deploy smart contracts and decentralized applications (dApps). Launched in 2015 by Vitalik Buterin and a team of co-founders, Ethereum extended the concept of blockchain beyond simple value transfer (as in Bitcoin) to programmable logic that can execute automatically when predefined conditions are met.

Smart contracts are self-executing programs stored on the Ethereum blockchain. They enable a wide range of applications without requiring trusted intermediaries: decentralized exchanges (Uniswap, Curve), lending and borrowing protocols (Aave, Compound), stablecoins (DAI, USDC), non-fungible tokens (NFTs), and decentralized autonomous organizations (DAOs). This ecosystem of applications, collectively called decentralized finance (DeFi), has grown to manage hundreds of billions of dollars in total value locked.

In September 2022, Ethereum completed "The Merge," transitioning from a proof-of-work (PoW) consensus mechanism to proof-of-stake (PoS). This change reduced Ethereum's energy consumption by approximately 99.95% and introduced a staking mechanism where validators lock up ETH as collateral to secure the network and earn rewards. The shift also introduced EIP-1559's fee-burning mechanism, which destroys a portion of transaction fees, making ETH potentially deflationary when network activity is high.

ETH's price is driven by network adoption and usage (more dApps and users mean more demand for ETH to pay transaction fees), the broader crypto market cycle (ETH is highly correlated with Bitcoin), monetary policy and real yields (like Bitcoin, ETH benefits from low real rates), and Ethereum-specific developments such as protocol upgrades, Layer 2 scaling solutions (Arbitrum, Optimism, Base), and institutional adoption including spot ETH ETFs.

For macro investors, Ethereum represents a different exposure profile than Bitcoin. While Bitcoin is increasingly positioned as "digital gold" and a monetary asset, Ethereum functions more as a technology platform whose value depends on its developer ecosystem, transaction throughput, and competitive position against alternative Layer 1 blockchains. This distinction means ETH tends to have higher beta to risk appetite and technology sector sentiment than Bitcoin does.
