From Civil Engineering to On‑Chain Specialist

James Check (aka Checkmate) is the co-founder of Checkonchain and one of the leading voices making onchain data accessible for everyday bitcoiners. Known for his ability to turn complex charts into compelling stories, James blends his engineering background with market analysis to help people see human behavior imprinted in bitcoin’s ledger. In this episode, James joins The Bitcoin Frontier to share why realized cap is one of the most powerful adoption metrics, how to interpret profit and loss across holders, and what onchain data is saying about the current cycle. We dig into the role of ETFs and treasury companies, the impact of derivatives on market structure, and why the future of onchain analytics remains deeply human.
