What is Ethereum (ETH)?
Ethereum is an open-source, decentralized blockchain network that represents the second generation of blockchain technology, building upon Bitcoin's foundation with significant advancements. Its native cryptocurrency, Ether (ETH), facilitates:
- Digital payments
- Creation/deployment of decentralized applications (DApps)
- Smart contract execution
With its current market valuation, Ethereum holds position as the second-largest cryptocurrency by market capitalization, trailing only Bitcoin. The network has revolutionized digital finance by introducing smart contract functionality, enabling users and developers to explore new technological frontiers.
Key Features of Ethereum
Decentralized Global Computer
Ethereum operates as a globally accessible computational platform where users:
- Maintain full control over digital assets
- Access traditionally centralized services without intermediaries
- Enjoy censorship-resistant applications
Smart Contract Ecosystem
Smart contracts enable:
- Automated lending/borrowing without traditional institutions
- Trustless transactions via blockchain-enforced agreements
- Elimination of third-party intermediaries
Governance Model
Ethereum employs decentralized governance where:
- Any community member can submit improvement proposals
- ETH holders vote on protocol changes
- Development remains community-driven
Ethereum's Economic Impact
The network has spawned multi-billion dollar industries including:
- Decentralized Finance (DeFi)
- Play-to-Earn blockchain gaming
- Non-Fungible Tokens (NFTs)
Current Ethereum Network Statistics:
- 2,900+ active projects
- $11+ trillion in processed value
- 41,000+ active validators (post-Merge)
Ethereum Operational Model
Consensus Mechanism Evolution
- Original (2015-2022): Proof-of-Work (PoW)
- Current (Post-Merge): Proof-of-Stake (PoS)
Account Architecture
Ethereum features two account types:
Externally Owned Accounts (EOAs)
- Controlled by private keys
- Can initiate transactions
Contract Accounts
- Smart contract-controlled
- Execute when triggered
Ethereum Virtual Machine (EVM)
The EVM serves as:
- Core execution environment for smart contracts
- Distributed state machine maintaining network consensus
- Foundation for all Ethereum operations
The Ethereum Merge Explained
The transition to ETH 2.0 involved three key phases:
Phase 0: Beacon Chain Launch (Dec 2020)
- Introduced parallel PoS chain
- Laid foundation for future upgrades
- Currently has 1.3M+ ETH staked
Phase 1: The Merge (Sept 2022)
- Combined PoW execution layer with PoS consensus layer
- Eliminated energy-intensive mining
- Maintained existing smart contract functionality
Phase 2: Sharding (2023-2024)
- Will partition network into 64 shard chains
- Dramatically improves scalability
- Reduces hardware requirements for nodes

Frequently Asked Questions
What makes Ethereum different from Bitcoin?
While both are blockchain networks, Ethereum enables smart contract functionality and decentralized applications, whereas Bitcoin primarily serves as digital currency.
How does the PoS system benefit Ethereum?
Proof-of-Stake reduces energy consumption by ~99.95%, increases security through staking incentives, and enables greater scalability through sharding.
Can I still mine Ethereum?
No, Ethereum mining ended with The Merge. Network security now comes from validators who stake ETH rather than miners solving computational puzzles.
What determines ETH's price?
Like all cryptocurrencies, ETH price is determined by market factors including:
- Supply/demand dynamics
- Network usage (gas fees)
- Overall crypto market trends
- Institutional adoption
How do I stake ETH?
You can stake ETH by:
- Running your own validator node (32 ETH required)
- Using staking pools
- Through centralized exchanges
Will Ethereum's value increase after the Merge?
While The Merge improved Ethereum's fundamentals, price depends on multiple factors. The upgrade does make ETH more attractive as:
- Staking yields are now available
- The asset becomes deflationary under certain conditions
- Institutional interest may grow due to ESG compliance
