Introduction to Ethereum (ETH)
Ethereum is an open, decentralized protocol that enables anyone to deploy applications on its blockchain. Designed as an open-source, decentralized solution, Ethereum was created with a clear purpose: to decentralize the web and offer alternatives to applications and platforms currently dominated by tech giants and multinational corporations.
While the term Ethereum primarily refers to the blockchain, it’s also commonly used to describe Ether (ETH), the native cryptocurrency of the network. ETH is the second-largest cryptocurrency by market capitalization, just behind Bitcoin.
As the accounting unit of the Ethereum blockchain, ETH is central to the ecosystem’s functionality. When users interact with Ethereum, they need ETH to execute operations—whether using decentralized apps (dApps), purchasing digital assets like NFTs, sending money, or other transactions.
Like Bitcoin, Ethereum operates on blockchain technology, a decentralized ledger maintained by servers worldwide. This means no single entity—government or corporation—controls Ethereum. The network is censorship-resistant and cannot be shut down.
Ethereum is pioneering the Web3 movement, a new internet era prioritizing privacy, data ownership, and decentralization. Since its launch in 2015, Ethereum has become a cornerstone of the digital future, attracting global enterprises and developers.
History of Ethereum
The Origins (2014–2015)
Ethereum was conceived by Vitalik Buterin, a Russian-Canadian programmer who published its whitepaper in 2014. Alongside co-founders like Gavin Wood and Charles Hoskinson, Buterin introduced smart contracts—self-executing protocols that power dApps for finance, gaming, social media, and more.
In July 2014, Ethereum held an Initial Coin Offering (ICO), raising $18 million by exchanging BTC for ETH. At launch (2015), 1 ETH was worth **$0.25; by 2023, it surpassed $1,850**—a 740,000% increase.
The DAO Hack (2016)
A pivotal moment came in 2016 when The DAO, a decentralized venture fund, was hacked, losing 3.6 million ETH. The community split:
- Majority: Supported a blockchain rollback ("hard fork") to refund investors.
- Minority: Rejected changes, continuing as Ethereum Classic (ETC).
Growth and Ethereum 2.0 (2017–Present)
- 2017–2018: ETH surged 14,500%, driven by ICO mania and dApp adoption.
- 2022: Ethereum transitioned from Proof of Work (PoW) to Proof of Stake (PoS) via "The Merge," reducing energy use by 99.95%.
- 2024–2027: Roadmap includes scalability upgrades (The Surge), MEV resistance (The Scourge), and Verkle Trees (The Verge).
Use Cases of Ethereum
1. Decentralized Finance (DeFi)
- DEXs: Trade cryptos without intermediaries (e.g., Uniswap).
- Lending/borrowing: Platforms like Aave and MakerDAO offer peer-to-peer services.
- Stablecoins: USDC, USDT, and DAI enable low-volatility transactions.
2. NFTs and Digital Ownership
- ERC-721 standard: Powers NFTs for art, gaming, and identity.
- Examples: Bored Ape Yacht Club (BAYC), OpenSea marketplace.
3. Tokenized Real-World Assets (RWA)
- Real estate: Platforms like RealT fractionalize property ownership.
- Corporate bonds: Société Générale tokenized €100M in 2019.
4. Gaming and Metaverse
- Play-to-earn: Axie Infinity, The Sandbox.
- Interoperability: NFTs allow cross-game asset transfers.
5. DAOs (Decentralized Autonomous Organizations)
- Community governance: Examples include Uniswap’s UNI token.
- Transparency: Votes and funds are managed on-chain.
Ethereum Ecosystem
| Category | Key Projects |

ETH Tokenomics
- Supply: No hard cap (~120M ETH in 2023).
- Inflation: Reduced post-Merge; deflationary during high usage (EIP-1559 burns fees).
- Staking: Earn rewards by locking ETH (4.3% APR).
Future of Ethereum
- 2024–2025: Proto-Danksharding (EIP-4844) to lower fees.
- 2026–2027: Full sharding for 100,000 TPS.
- Beam Chain (ETH 3.0): Quantum-resistant cryptography, 1 ETH staking minimum.
