In response to the AI-driven shock in global demand for computing power, large players in the Bitcoin mining industry have been forced to make significant strategic shifts to remain competitive.
MARA — the largest Bitcoin miner in the world by hashrate — is emerging as one of the more well-positioned beneficiaries of these changing tides, having transitioned from an “asset-light” strategy (via hosted mining at third-party facilities) to an “asset-heavy” approach (owning its own land, power, and infrastructure) just ahead of the AI compute wave in 2024/25.
I sat down with MARA CEO Fred Thiel to discuss how these shifting industry dynamics are playing out in practice — as well as his perspective on how key mining-related security and infrastructure issues may evolve in the coming months and years.
In this episode, we cover:
— How MARA scaled from near-zero hash rate in 2020 to the largest Bitcoin miner globally by the end of 2023
— Key differences between operating Bitcoin mining facilities versus AI data centers, and where the two models meaningfully intersect
— Why ownership of power generation —rather than reliance on PPAs— may represent a durable competitive edge for miners and AI data center operators over time
— Why Bitcoin may be entering its “IPO phase,” and why recent price corrections could reflect increasing market maturity rather than structural weakness
We also explore more technical and often under-discussed topics —such as heat reuse, open-source mining technologies, and the implications of US policy goals around Bitcoin mining.
This episode offers a grounded, operator-level view of where Bitcoin mining is headed, informed by one of the most consequential leaders in the public mining sector.

There are few people as close to the frontlines of Bitcoin privacy as Cake Wallet COO Seth for Privacy. After cutting his teeth building for Monero, Seth turned his focus to Bitcoin in 2022, with the view that making Bitcoin more private would ultimately help more people than focusing on a smaller niche target group alone.
Isabel Foxen Duke sits down with [[alloc] init] co-founder Misha Komarov and Head of Protocol Research Clara Shikhelman to examine PIPEs, a cryptographic framework that utilizes witness encryption—a primitive long dismissed as purely theoretical—to unlock advanced Bitcoin programming without a soft fork.
The first fully specified post-quantum signature scheme for Bitcoin has been proposed to the Bitcoin mailing list.
To date, post-quantum Bitcoin discussions have largely centered on which digital signature schemes offer the strongest cryptographic security against a quantum adversary.
Paul Sztorc founder and CEO of LayerTwo Labs and author of Bitcoin Improvement Proposals 300 and 301 (Drivechains), has been one of Bitcoin's most persistent—and controversial—thinkers, advocating for merge-mined sidechains as a way to dramatically expand Bitcoin's functionality while preserving the security of the base layer.
