What is Ethereum?
Ethereum is a decentralized blockchain platform that enables developers to build and deploy smart contracts and decentralized applications (DApps). Launched in 2015 by Vitalik Buterin, Ethereum introduced programmable blockchain capabilities beyond simple value transfer.
Key Features
Ethereum's primary innovation is the Ethereum Virtual Machine (EVM), which allows developers to write Smart Contracts in programming languages like Solidity. These Smart Contracts automatically execute when predefined conditions are met, enabling trustless transactions and decentralized automation.
The Merge: Proof of Stake
In 2022, Ethereum transitioned to proof-of-stake consensus mechanism, dramatically reducing energy consumption by over 99%. This upgrade made Ethereum more environmentally friendly while maintaining Security through Staking by validators.
Ether (ETH)
ETH is the native Cryptocurrency of Ethereum. It's used to pay for Transaction Fees (gas) and serves as the economic incentive for validators to secure the network. ETH can be staked to earn rewards and is also used as collateral in various DeFi protocols.
Ecosystem Applications
The Ethereum ecosystem hosts thousands of applications ranging from decentralized finance (DeFi) protocols to NFT marketplaces, gaming applications, and more. The network processes millions of transactions daily and has become the de facto platform for Web3 development.
Layer 2 Solutions
Ethereum continues to evolve with layer 2 scaling solutions like Arbitrum, Optimism, and Polygon, which improve transaction throughput and reduce fees while maintaining Ethereum's Security guarantees.
Important Points
• Ethereum enables smart contract functionality
• The network transitioned to environmentally-friendly PoS
• ETH is used for gas fees and staking
• Thousands of DApps run on Ethereum
• Layer 2 solutions improve scalability
