AI, Blockchain, Local LLM — Notes from the Trenches
HakHubNet is whackur’s personal tech blog. The focus is on AI, blockchain/Web3 (Solidity), local LLM, and physical AI. Posts come from actual experiments, not just reading docs.

What this blog covers
Four areas, all approached hands-on. If something breaks, that gets written up too.
- AI — LLM internals, fine-tuning, agent design
- Blockchain/Web3 — Solidity contracts, EVM mechanics, DeFi protocols
- Local LLM — on-device inference, model optimization, privacy
- Physical AI — robotics, edge AI, sensor pipelines

Bilingual: Korean + English
Korean is the primary language. Some posts are also available in English, written for an English-speaking audience rather than translated literally.
- Korean posts: concept breakdowns and hands-on notes
- English posts: same topics, rewritten for a different reader
