Blockspace - A Bitcoin Podcast

James Check, Co-Founder of Check on Chain, joins us to talk about the current state of Bitcoin in 2026. James breaks down why Bitcoin decoupled from the wider market in late 2025, the massive sell-side pressure from long-term holders, and why on-chain metrics point to a bear market phase. We also explore the "extraordinary" nature of ETF flows, the quantum computing debate, and why gold and Bitcoin are ultimately the same trade. Subscribe to the newsletter!

We break down the difference between bits and qubits, explain why Shor's algorithm threatens elliptic curve cryptography, and debate the fate of Satoshi's vulnerable coins. It’s a deep dive into encryption, timeline predictions, and the massive coordination challenge facing the Bitcoin network to upgrade before it's too late.

Charlie and Colin join us to talk about the existential risk of quantum computing. We break down Nick Carter's latest research, the timeline for a potential quantum break, and the 2 million Bitcoin currently at risk. We debate the ethics of "burning" Satoshi's coins to save the network, the technical challenges of forking to quantum-resistant signatures, and why the next big Bitcoin civil war might be fought over physics.
