Blockchain Ethereum

Purpose

Guide to Ethereum protocol engineering covering execution layer, consensus layer, staking, L2 scaling, and protocol evolution through EIPs. Covers both client implementation and protocol-level design.

Input Context

• Ethereum layer (execution/consensus/L2)
• Client implementation (geth/reth/Nethermind/Erigon)
• Protocol component (EVM/staking/EE/etc.)
• EIP/research area
• Performance requirements (TPS, latency, cost budget)

Output Artifact

Technical analysis or implementation guide covering the specified Ethereum protocol component with architecture, mechanisms, and trade-offs.
