Ethereum vs Bitcoin: A Comprehensive Comparison

Introduction

The world of cryptocurrency is dominated by two giants: Bitcoin and Ethereum. While both are decentralized blockchains, they have distinct purposes, designs, and use cases. Understanding the differences and similarities between these two cryptocurrencies is crucial for investors, developers, and enthusiasts.

History and Background

Bitcoin was released in 2009 by Satoshi Nakamoto, a pseudonymous individual or group. Ethereum was founded in 2015 by Vitalik Buterin, a well-known programmer and cryptocurrency enthusiast.

Key Differences

Purpose: Bitcoin’s primary purpose is to serve as a digital currency, while Ethereum focuses on decentralized applications and smart contracts.
Blockchain: Bitcoin uses a proof-of-work (PoW) consensus algorithm, whereas Ethereum is transitioning to proof-of-stake (PoS).
Smart Contracts: Ethereum supports complex smart contracts, whereas Bitcoin’s smart contract functionality is limited.
Supply: Bitcoin’s supply is capped at 21 million, whereas Ethereum has no fixed supply.
Transaction Speed: Ethereum’s transaction speed is faster, with 15-20 transactions per second (TPS), compared to Bitcoin’s 7 TPS.

Similarities

Decentralized: Both Bitcoin and Ethereum are decentralized, open-source blockchains.
Cryptographic Security: Both use advanced cryptography for secure transactions.
Open-Source: Both have open-source codebases.
