Introduction
Ethereum represents a revolutionary leap forward in blockchain technology, introducing a Turing-complete programming language that enables developers to create smart contracts and decentralized applications (dApps) with unprecedented flexibility. This whitepaper outlines Ethereum's core concepts, technical architecture, and potential applications.
Historical Context
Bitcoin's Dual Innovations
- Digital Currency: Bitcoin introduced decentralized peer-to-peer electronic cash.
- Blockchain Consensus: The proof-of-work blockchain solved decentralized transaction ordering.
Limitations of Bitcoin
- Scripting language lacks Turing-completeness
- Value-blind UTXO model
- No internal state maintenance
- Blockchain-blind contracts
Ethereum Fundamentals
Accounts
- External Owned Accounts (EOAs): Controlled by private keys
- Contract Accounts: Governed by code with balance, storage, and executable functions
Transactions and Messages
- Contain recipient, value, data, gas limits, and digital signatures
- Can trigger contract code execution
State Transition Function
APPLY(S,TX) → S':
1. Validate transaction
2. Deduct gas fee
3. Execute code (if contract)
4. Update stateEthereum Virtual Machine (EVM)
- Stack-based architecture with 256-bit words
- Memory, storage, and execution environment
- Gas system prevents infinite loops
Key Innovations
Smart Contracts
Self-executing agreements with:
- Customizable ownership rules
- Complex financial logic
- Autonomous organization capabilities
Mining Protocol
Modified GHOST protocol:
- Includes uncle blocks in chain weight
- 5-generation family limit
- 87.5% reward for uncles
Gas Economy
- Computation measured in gas units
- Dynamic fee market
- Prevents spam and optimizes resource allocation
Applications
Financial Systems
- Token standards (e.g., ERC-20)
- Derivatives and prediction markets
- Decentralized exchanges
Non-Financial Uses
- Identity management
- Supply chain tracking
- Governance systems
- Distributed file storage
Technical Considerations
Scalability Solutions
- Patricia Merkle Trees for state storage
- Light client support
- Sharding roadmap (future implementation)
Security Model
- 51% attack resistance
- Formal verification capabilities
- Gas limit protections
FAQ
What makes Ethereum different from Bitcoin?
Ethereum introduces Turing-complete smart contracts, account-based state tracking, and a broader application scope beyond digital cash.
How are Ethereum transactions processed?
Transactions trigger state transitions through the EVM, with gas fees compensating miners for computation.
What is gas?
Gas represents computational work units, paid in ether. It prevents infinite loops and allocates network resources.
Can Ethereum scale for mass adoption?
Current solutions include optimized state storage and future plans for sharding and layer-2 solutions like rollups.
