What is Ethereum (ETH)?
Ethereum is a decentralized blockchain platform that enables smart contracts and decentralized applications (dApps). It creates a peer-to-peer network where transactions and applications run securely without intermediaries. Ethereum’s native cryptocurrency, Ether (ETH), powers this ecosystem, making it a cornerstone of Web3 technology.
How Does Ethereum (ETH) Work?
Ethereum operates through a global network of nodes (computers) that collectively form the Ethereum Virtual Machine (EVM). The EVM executes smart contracts—self-enforcing agreements written in code—and records all transactions on a public ledger. Here’s how it functions:
- Gas Fees: Users pay transaction fees (denominated in Gwei, a fraction of ETH) to execute operations.
- Consensus Mechanism: Ethereum transitioned from Proof-of-Work (PoW) to Proof-of-Stake (PoS) in 2022 ("The Merge"), reducing energy consumption by 99.95%.
- Decentralization: No single entity controls the network, ensuring transparency and security.
