$ETH
Ethereum is a decentralized blockchain platform that enables smart contracts and decentralized applications (DApps) to run without the need for intermediaries. Here’s a breakdown of how it works:
1. Core Concepts
Blockchain: A decentralized, distributed ledger that records transactions across many computers.
Smart Contracts: Self-executing contracts with predefined rules, running on Ethereum’s blockchain.
Ethereum Virtual Machine (EVM): A global decentralized computer that executes smart contracts.
Ether (ETH): Ethereum’s native cryptocurrency, used to pay for transactions and computational power.
2. How Ethereum Works
Transactions: Users send ETH or interact with smart contracts by submitting transactions.
Consensus Mechanism: Ethereum transitioned to Proof of Stake (PoS) with Ethereum 2.0, where validators stake ETH to secure the network instead of mining (Proof of Work).
Gas Fees: Transactions require a fee (gas), which depends on network activity and computational complexity.
