Introduction to Ethereum
Ethereum is a decentralized computing platform that enables developers to build and deploy smart contracts and decentralized applications (DApps). Unlike traditional applications that run on centralized servers, Ethereum operates on a global network of thousands of computers, meaning no single entity controls it.
While Ethereum shares similarities with Bitcoin and other cryptocurrencies by allowing digital currency transfers, its capabilities extend far beyond that. Developers can write custom code that interacts with applications created by other users, making Ethereum an incredibly flexible platform capable of running complex programs.
Key Features of Ethereum
Decentralized Nature
- Runs simultaneously on thousands of machines worldwide
- No single owner or controlling entity
- Resistant to censorship and shutdowns
Smart Contracts
- Self-executing contracts with terms written into code
- Automatically enforce agreements without intermediaries
- Can facilitate complex transactions and applications
Ethereum Virtual Machine (EVM)
- Runtime environment for smart contracts
- Converts smart contracts into computer-readable instructions
- Ensures consistency across the network
Ethereum vs. Bitcoin
| Feature | Ethereum | Bitcoin |
|---|---|---|
| Primary Purpose | Platform for DApps | Digital currency |
| Programmability | Turing-complete | Limited scripting |
| Block Time | 12-19 seconds | 10 minutes |
| Consensus | Transitioning to Proof of Stake | Proof of Work |
| Native Currency | Ether (ETH) | Bitcoin (BTC) |
Ethereum's Native Currency: Ether (ETH)
- Ether powers the Ethereum network
- Used to pay for transaction fees and computational services
- Different from Ethereum itself (the protocol)
- Can be traded, used as collateral, or to interact with DApps
How Ethereum Works
- Transaction Initiation: Users send transactions to the network
- Smart Contract Execution: Contracts run on the EVM when triggered
- Mining/Validation: Nodes validate transactions and add them to blocks
- State Updates: All nodes update their blockchain copies
Ethereum Blockchain
The Ethereum blockchain serves as a distributed database that:
- Stores all transaction data
- Maintains network state
- Uses cryptographic hashes to link blocks securely
Unlike Bitcoin, Ethereum doesn't have a fixed block size limit but uses a gas limit system to manage network capacity.
Smart Contracts Explained
Smart contracts are:
- Pieces of code stored on the blockchain
- Self-executing when predetermined conditions are met
- Immutable once deployed
- Visible to all network participants
Example: A simple contract could send a message when it receives 2 ETH.
Ethereum's Founders and History
- Proposed in 2013 by Vitalik Buterin
- Launched in 2015 with an initial supply of 72 million ETH
- Funded through one of the first successful ICOs
- Notable events include the DAO hack and subsequent hard fork
Ethereum 2.0 (ETH 2.0)
Upcoming upgrades include:
- Transition to Proof of Stake (PoS)
- Implementation of sharding for scalability
- Improved security and efficiency
- Potential for faster transaction times
Getting Started with Ethereum
How to Buy ETH
- Cryptocurrency Exchanges: Platforms like Binance, Coinbase
- Peer-to-Peer Markets: Direct purchases from other users
- Credit/Debit Cards: Some platforms offer instant purchases
Storing ETH
- Hot Wallets: Connected to internet (mobile/desktop apps)
- Cold Wallets: Offline storage (hardware wallets)
- Exchange Wallets: Convenient but less secure

Frequently Asked Questions
What's the difference between Ethereum and Bitcoin?
While both are cryptocurrencies, Ethereum is primarily a platform for decentralized applications, while Bitcoin was created as a digital currency and store of value.
How do I create a smart contract?
You'll need to learn Solidity (Ethereum's programming language) and use development tools like Remix IDE or Truffle Suite.
Is Ethereum secure?
Ethereum employs robust cryptography and decentralized consensus mechanisms. However, smart contract vulnerabilities can present risks if not properly audited.
When will Ethereum 2.0 launch?
The transition is happening in phases, with the full implementation expected over several years starting from 2020.
Can I earn interest on my ETH?
Yes, through DeFi lending platforms or staking (once Proof of Stake is fully implemented).
