Ethereum (ETH) is an open-source, decentralized blockchain network that builds on Bitcoin's innovations while introducing unique improvements. Its native cryptocurrency, Ether (ETH), facilitates digital payments and serves as a platform for deploying immutable decentralized applications (DApps) and smart contracts.
As the second-largest cryptocurrency by market cap, Ethereum revolutionized the industry by introducing smart contracts—enabling decentralized finance (DeFi), NFTs, and crypto gaming. The network hosts over 2,900 projects and has processed $11+ trillion in transactions.

What Makes Ethereum Unique?
Ethereum functions as a "global computer," empowering users with control over digital assets and access to decentralized services. Key differentiators:
- Decentralized Finance (DeFi): Users can collateralize assets for loans without intermediaries.
- Censorship Resistance: Applications run on a global node network, reducing fraud risks.
- Community Governance: ETH holders vote on proposals to guide network development.
How Does Ethereum Work?
Consensus Mechanisms
- Proof of Work (PoW, 2015–2022): Miners competed to solve equations for block rewards.
- Proof of Stake (PoS, post-Merge): Validators stake 32 ETH to propose/validate blocks, reducing energy use by 99.95%.
Account Types
- External Accounts: User-controlled (via private keys).
- Smart Contracts: Code-governed accounts that execute predefined actions.

Ethereum’s Technology
Ethereum Virtual Machine (EVM)
The EVM is Ethereum’s computational engine, executing smart contracts across thousands of nodes. It enables:
- DeFi protocols
- NFT marketplaces
- Decentralized exchanges (DEXs)
Token Standards
- ERC-20: Fungible tokens (e.g., stablecoins).
- ERC-721: Non-fungible tokens (NFTs).
- ERC-1155: Hybrid fungible/NFT tokens.
The Ethereum Merge: Key Phases
| Phase | Description | Date |
|-------------|-----------------------------------------------------------------------------|--------------------|
| Phase 0 | Launched Beacon Chain (PoS testnet) | Dec 1, 2020 |
| The Merge | PoW mainnet merged with Beacon Chain | Sep 15, 2022 |
| Dencun Upgrade | Introduced Proto-Danksharding (EIP-4844) to reduce fees | Mar 13, 2024 |
ETH Price History & Tokenomics
- ICO Price (2014): $0.31 per ETH.
- All-Time High: $4,878 (Nov 2021).
- Current Supply: ~120 million ETH (inflationary).
Spot Ethereum ETF Update
The SEC approved 19b-4 filings for spot ETH ETFs on May 23, 2024. Final S-1 approvals are pending, sparking a 25% price surge in May 2024.
Ethereum’s Founders
- Vitalik Buterin: Published Ethereum whitepaper at age 19; advocates for decentralized governance.
- Gavin Wood: Created Solidity and Polkadot.
- Charles Hoskinson: Left to develop Cardano (ADA).
FAQs
1. What is ETH used for?
ETH pays gas fees, stakes in PoS, and trades as a digital asset.
2. How does PoS improve Ethereum?
It reduces energy consumption and increases scalability.
3. What’s the difference between ETH and Bitcoin?
Ethereum supports smart contracts; Bitcoin is primarily a store of value.
4. Can ETH be mined after the Merge?
No—validators replace miners.
5. When will the Ethereum ETF launch?
S-1 approvals could take weeks/months (as of May 2024).
6. What’s Ethereum’s max supply?
ETH has no hard cap, unlike Bitcoin’s 21 million.
