What Ethereum Is — and How It Differs From Bitcoin

Ethereum is the world's second-largest cryptocurrency network by market value — but its purpose is fundamentally different from Bitcoin's. Where the original blockchain was built primarily for peer-to-peer payments, Ethereum was designed as a programmable platform on which developers can build decentralized applications, known as Dapps, and run code that executes automatically when set conditions are met.

The network was launched in 2015 by the Russian-Canadian developer Vitalik Buterin, who argued that Bitcoin's blockchain was too limited for anything beyond simple value transfer. Ethereum's answer was the Ethereum Virtual Machine (EVM), the core layer that interprets and executes smart contracts and secures the network. The classic illustration: if a train runs two hours late, a smart contract could automatically compensate the passenger — no trusted third party required, because the blockchain itself guarantees the outcome.

That programmability has drawn thousands of developers, who have built Dapps across finance, video games, real estate, logistics and cloud services. Any token created on Ethereum must comply with the ERC-20 standard. The network also has its own native currency, Ether (ETH), which pays for transactions on Ethereum and can transfer value between addresses just as Bitcoin does. The project continues to work on scalability, security and user experience.

Why Smart Contracts, Not Payments, Define Ethereum's Position

Vitalik Buterin's Bet: A Blockchain That Runs Code

The source is a primer rather than a news story, but it captures the strategic distinction that still separates Ethereum from Bitcoin. Buterin's central claim was that a blockchain restricted to payments could not support more complex services. By adding a virtual machine that executes code on-chain, Ethereum turned the blockchain from a ledger into a platform — the foundation of its lasting position as the number-two cryptocurrency.

The ERC-20 Standard as Ethereum's Competitive Moat

The network's economic strength rests on network effects. The ERC-20 standard makes it inexpensive for projects to issue tokens and for wallets and exchanges to support them, which in turn attracts more developers to the EVM. The sector examples in the article — finance, gaming, real estate, logistics, cloud — are illustrative rather than evidence of specific products, but they indicate where Ethereum's developers have concentrated.

Proof of Work: The Detail That Hasn't Aged Well

One technical claim in the source is outdated. It describes Ether as being issued through proof-of-work mining, the energy-intensive process Bitcoin still uses. Ethereum abandoned that mechanism in the September 2022 "Merge," switching to proof-of-stake and cutting the network's energy use dramatically. Readers should treat any description of Ethereum as a proof-of-work system as a pre-2022 picture.

What to Verify Before Treating This Explainer as Current

This explainer is background reading, not breaking news — and it contains one stale detail worth flagging before it shapes anyone's view of Ethereum:

  • The article says Ether is issued through proof-of-work mining. That mechanism no longer exists: Ethereum moved to proof-of-stake in the September 2022 "Merge," so any energy-intensity arguments based on the old model do not apply to today's network.
  • For anyone evaluating a token built on Ethereum, the ERC-20 standard is the practical compatibility test the article highlights — tokens that follow it are supported by the majority of wallets and exchanges.
