#Ethereum (ETH) — the world’s leading programmable blockchain — goes beyond digital currency by enabling smart contracts, decentralized finance (DeFi), NFTs, and decentralized apps (dApps).
Here’s a full breakdown 👇
🔹 What Ethereum Is
A decentralized blockchain platform that allows developers to build and deploy applications without intermediaries.
Created by Vitalik Buterin and launched in 2015.
Its native token is Ether (ETH) — used to pay for computation and transaction fees (gas).
🔹 Key Innovations
Smart Contracts
Self-executing programs stored on the blockchain.
Execute automatically when conditions are met (e.g., “if X happens, send Y ETH to Z”).
Power DeFi, NFTs, DAOs, games, and more.
Ethereum Virtual Machine (EVM)
The global, decentralized computer that runs smart contracts.
Every Ethereum node runs the same computations, ensuring trust and consistency.
Ether (ETH)
The cryptocurrency used to pay “gas” — fees required to perform operations on the network.
Also acts as a store of value and medium of exchange.
🔹 Proof of Stake (PoS) & The Merge
In September 2022, Ethereum switched from Proof of Work to Proof of Stake, an upgrade called The Merge.
✅ Reduced energy use by 99.9%
✅ Introduced staking instead of mining
✅ Paved the way for future scalability upgrades
🔹 Scalability & Layer 2 Solutions
Ethereum’s base layer can handle ~15 transactions per second.
To improve speed and reduce fees, Layer 2 networks (built on top of Ethereum) are used, such as:
Base (by Coinbase)
These rollups process transactions off-chain and post summaries back to Ethereum.
🔹 Common Use Cases
💰 DeFi – lending, borrowing, trading (Aave, Uniswap, MakerDAO)
🎨 NFTs – digital art & collectibles (OpenSea, Blur)
🏛 DAOs – decentralized governance (ENS DAO, MakerDAO)
🎮 Blockchain games – play-to-earn and metaverse projects
💸 Stablecoins – USDC, DAI, and USDT live on Ethereum
🔹 Upcoming Upgrades
Danksharding / Proto-Danksharding (EIP-4844) – reduces gas fees for Layer 2s
Verkle Trees – improves storage and node efficiency
Account Abstraction (ERC-4337) – enables “smart wallets” with recovery options and advanced features
🔹 Challenges
High gas fees during network congestion
Complex user experience (wallets, gas settings, etc.)
Strong competition from newer blockchains (Solana, Avalanche, etc.)
🔹 ETH as an Asset
Used for staking to earn rewards (~3–5% APR).
Burn mechanism via EIP-1559 makes ETH potentially deflationary — reducing supply over time.
Seen as both a utility token (for gas) and a store of value (digital oil).
