The convergence of artificial intelligence (AI) and blockchain technology presents transformative opportunities for decentralized systems like Ethereum. As on-chain computational power grows, we anticipate the development of sophisticated models for network management, transaction monitoring, security auditing, and beyond—enhancing Ethereum's efficiency and security.
Ethereum's Technical Architecture
Core Data Structures
- Chain Configuration: Unique identifiers (ChainID) differentiate Ethereum networks (mainnet/testnets) and mark protocol upgrades (e.g., DAOForkBlock, ConstantinopleBlock).
- Genesis Block: Immutable foundational block containing consensus rules, mining rewards (pre-merge), and gas parameters.
- World State: A Merkle Patricia Trie (MPT) storing all account data, with each leaf node representing an account's balance, storage, and contract code.
Transaction Mechanics
- Gas System: Fee = Gas Used × Gas Price. Users set gas prices to prioritize transactions, with limits preventing infinite loops.
- Transaction Pool: Prioritizes executable transactions (higher gas) over queued ones, with local transactions receiving preferential treatment.
Consensus Evolution
- Proof-of-Stake (PoS): Post-merge (2022), validators are randomly selected every 12-second slot. One proposer creates blocks while committees verify legitimacy.
Cryptographic Foundations
- ECDSA: Uses secp256k1 curve for signatures (R+S+V recovery fields).
- MPT: Combines Merkle tree hashing with Patricia trie compression for efficient, secure state storage.
Execution Layer
- Ethereum Virtual Machine (EVM): Stack-based, Turing-complete runtime for smart contracts, executing Solidity-compiled bytecode.
Ethereum's Challenges
Security Risks
- Smart Contract Vulnerabilities: Logic flaws (e.g., Blueberry Protocol's $1.4M exploit), reentrancy attacks, and access control issues.
- Investment Threats: Scam tokens (rug pulls, honeypots), junk coins, and Ponzi schemes targeting inexperienced users.
Efficiency Limitations
- Network Congestion: Low TPS escalates gas fees during peak demand.
- DApp Discovery: No personalized recommendation systems for decentralized applications.
- Capital Inefficiency: Over-collateralization in DeFi lending reduces liquidity.
