Introduction to Ethereum
Ethereum is an open-source, blockchain-based platform that enables smart contracts and decentralized applications (DApps). At its core, Ethereum features:
- A decentralized virtual machine (Ethereum Virtual Machine) that executes peer-to-peer contracts
- Native cryptocurrency called Ether (ETH) that fuels network operations
- Smart contract functionality that allows programmable, self-executing agreements
Developed by programmer Vitalik Buterin between 2013-2014, Ethereum was conceived as "the next-generation cryptocurrency and decentralized application platform." The project launched in 2014 through an ICO crowdfunding campaign and has since become the second-largest cryptocurrency by market capitalization.
Key Differentiators
What sets Ethereum apart from other blockchain platforms?
- Smart Contracts: Self-executing code stored on the blockchain that runs when predetermined conditions are met
- Token Creation: Ability to generate custom tokens for DApps through smart contracts
- Uncle Blocks: Incorporation of shorter blockchain branches to improve transaction volume
- Proof-of-Stake: Energy-efficient consensus mechanism (currently in testing)
- Plasma: Proposed sidechain solution to increase throughput
- State Channels: Off-chain transaction networks similar to Bitcoin's Lightning Network
- Sharding: Future implementation to improve scalability through parallel processing

Mining Economics
Hardware Considerations
- GPU Mining: Primary method for ETH
Recommended Specs:
- AMD graphics cards (4GB+ VRAM)
- Efficient power supplies
- Stable motherboard configurations
Profitability Factors
- Hashrate: Measured in MH/s (mega-hashes per second)
- Power Consumption: Watts per MH/s
- Network Difficulty: Adjusts every block (~15 secs)
Sample GPU Performance Table:
| Graphics Card | Hashrate (MH/s) | Power Draw (W) |
|---|---|---|
| RX 580 | 28-30 | 130-150 |
| RTX 3060 Ti | 60-62 | 120-140 |
Future Outlook
Ethereum continues evolving with:
- Ongoing transition to Ethereum 2.0
- Layer 2 scaling solutions
- Growing DeFi and NFT ecosystems
- Institutional adoption through EEA
Frequently Asked Questions
What makes Ethereum different from Bitcoin?
While Bitcoin focuses on peer-to-peer payments, Ethereum enables programmable money through smart contracts and decentralized applications.
How do Ethereum transactions work?
Transactions require gas (paid in ETH) to execute operations on the network. Each transaction includes:
- Recipient address
- Data payload
- Gas limit and price
- Digital signature
When will Ethereum switch to Proof-of-Stake?
The transition is underway through Ethereum 2.0 upgrades, with full implementation expected in the coming years.
What determines Ethereum's mining profitability?
Key factors include:
- Hardware efficiency (hashrate vs. power consumption)
- ETH market price
- Network difficulty
- Electricity costs
Can Ethereum scale to handle global adoption?
Scaling solutions like sharding, rollups, and plasma aim to increase throughput from ~15 to thousands of transactions per second.
