Blockchain Core

Purpose

Guide core blockchain protocol engineering covering consensus mechanisms, state machine design, P2P networking, mempool architecture, MEV economics, and node implementation. This skill enables building and analyzing blockchain protocols from first principles.

Input Context

• Consensus family (Nakamoto/BFT/hybrid/DAG)
• State machine model (UTXO/account/WASM)
• Network topology (permissionless/permissioned/hybrid)
• Performance requirements (TPS, finality time, node requirements)
• Security model (adversary threshold, economic security assumptions)
• Implementation language (Go/Rust/C++)
