Ethereum

Definition of Ethereum

Ethereum is a decentralized global software platform powered by blockchain technology, primarily used for building and deploying smart contracts and decentralized applications (DApps). Ethereum’s native cryptocurrency is Ether (ETH), which is used to compensate participants for computations performed on the network and can also be accepted as payment for goods and services.

Ethereum vs Bitcoin Comparison

Feature	Ethereum	Bitcoin
Purpose	Decentralized application platform	Digital currency primarily for transactions
Technology	Smart contracts and DApps	Transactions in a peer-to-peer network
Token	Ether (ETH)	Bitcoin (BTC)
Consensus Mechanism	Proof of Stake	Proof of Work
Support for Scripts	Yes, supports Turing-complete scripts	No, primarily for transactions
Supply Limit	No hard cap (inflationary)	21 million coins cap

Examples

Smart Contracts: Self-executing contracts where the terms are directly written into code. Think of them as vending machines for agreements.
Decentralized Applications (DApps): Applications that run on a peer-to-peer network, not controlled by any single entity. Imagine apps without a boss!

Blockchain: The underlying technology that ensures Ethereum’s secure, distributed nature.
Decentralized Finance (DeFi): Financial services using smart contracts on the blockchain to create decentralized applications, bypassing traditional financial intermediaries.
Web3: The next evolution of the internet, utilizing decentralized blockchain technology.
Proof of Work vs. Proof of Stake: Consensus mechanisms used to validate transactions on a blockchain.

Frequently Asked Questions

FAQ

Q1: What is Ether, and how is it different from Ethereum?
A1: Ether (ETH) is the native cryptocurrency of the Ethereum network, whereas Ethereum is the platform itself where Ether is used to pay for computational work and transaction fees.

Q2: Can Ethereum be used for purposes other than currency?
A2: Absolutely! Ethereum’s smart contracts enable a plethora of applications beyond simple transactions, including finance, real estate, and even social networks.

Q3: Why was Ethereum created?
A3: Ethereum was created to offer a platform for building decentralized applications and smart contracts with a programming language that enables flexibility and creativity.

Q4: How is Ethereum transitioning from Proof of Work (PoW) to Proof of Stake (PoS)?
A4: Ethereum aims to become more energy-efficient by using PoS, which requires validators to stake their ETH to validate transactions instead of using energy-heavy mining.

Q5: Can I earn with Ethereum without buying ETH?
A5: Yes! You can participate in staking, mining, or contributing to various DeFi projects to potentially earn rewards in ETH.
