Ethereum (ETH) is more than just a cryptocurrency—it is a decentralized platform that has transformed how the world thinks about blockchain technology. Since its launch in 2015, Ethereum has grown from a simple smart contract network to a full-fledged ecosystem powering decentralized finance (DeFi), NFTs, Web3 applications, and more.
But in 2026, the question many investors ask is: Is Ethereum still relevant? Or has it been outpaced by newer, faster blockchains?
1. Ethereum’s Core Advantage: Smart Contracts
Ethereum was the first blockchain to implement Turing-complete smart contracts. This means developers can code programs that run exactly as programmed without downtime, fraud, or interference.
- Why it matters: Smart contracts automate agreements without middlemen, saving billions in potential fees.
- Use case: DeFi platforms like Aave and Uniswap rely on Ethereum’s contracts to manage billions in digital assets safely.
Even with faster blockchains emerging, Ethereum’s network effect keeps it at the top. Developers, users, and capital are already locked into the ecosystem, making it hard to replace.
2. Ethereum 2.0 and The Merge: Energy Efficiency & Security
In 2022, Ethereum transitioned from Proof-of-Work (PoW) to Proof-of-Stake (PoS), a move called The Merge.
- Impact on energy: Ethereum now consumes ~99% less electricity than before.
- Impact on security: PoS makes it extremely costly for bad actors to attack the network.
This upgrade wasn’t just technical—it was strategic. Many new blockchains advertise speed and low fees, but Ethereum offers a combination of security, decentralization, and developer adoption that few can match.
3. DeFi on Ethereum: Why It’s Still the Hub
Decentralized finance exploded on Ethereum because it offered composable infrastructure—protocols could be built on top of each other seamlessly.
- TVL (Total Value Locked): Even in 2026, Ethereum-based DeFi accounts for the majority of TVL in crypto.
- Projects to watch: MakerDAO, Uniswap, Aave, Lido—these protocols have billions locked in assets.
Key insight: DeFi isn’t just a trend; it’s the backbone of Web3 finance. Ethereum remains the most trusted platform to experiment in this space.
4. NFTs and Ethereum: Not Just Art
NFTs exploded in 2021, and Ethereum was the dominant blockchain for digital collectibles. While some blockchains offer lower fees, Ethereum maintains liquidity, user base, and marketplace adoption.
- Real utility: Beyond art, NFTs now power gaming, memberships, intellectual property, and identity verification.
- Layer 2 solutions: Optimism and Arbitrum reduce fees, making NFT creation and trading more accessible without sacrificing security.
5. Layer 2 & Scaling: Overcoming Gas Fees
Ethereum’s main criticism has always been high gas fees. But the ecosystem is evolving:
- Layer 2 solutions: Rollups like Arbitrum, Optimism, and zkSync allow faster transactions with lower fees.
- Impact: Developers can build mass-market applications without pricing out users.
Ethereum isn’t just surviving—it’s adapting.
6. Risks Every ETH Holder Should Know
Ethereum is not risk-free. Any investment requires caution
