What is Bitcoin?
Bitcoin is a decentralized digital currency, also known as cryptocurrency, that operates without central authority. It represents the first successful implementation of network-based money, revolutionizing how value is transferred globally. Key characteristics:
- Peer-to-Peer System: Transactions occur directly between users
- Blockchain Technology: Secured through cryptographic proof
- Limited Supply: Capped at 21 million coins
- Borderless: Can be sent/received anywhere worldwide
What is Ethereum?
Ethereum is a programmable blockchain platform created by Vitalik Buterin that extends beyond digital currency. Its core innovations include:
- Smart Contracts: Self-executing agreements with predefined rules
- Decentralized Applications (DApps): Censorship-resistant software
- Ether (ETH): The native cryptocurrency used for transaction fees
