The Bitcoin mining industry faces unprecedented challenges following the fourth halving, with hash prices hitting historic lows and operational margins thinning. Nangeng Zhang, Founder and CEO of Canaan Inc.—the company behind the first Bitcoin mining ASIC—shared insights on the evolving landscape, chip efficiency trends, and emerging opportunities in an exclusive interview with Bitcoin Magazine.
The Open-Source Foundation of Bitcoin Mining
Canaan's 2013 launch of the AvalonMiner ASIC marked a watershed moment for Bitcoin mining efficiency. Zhang emphasized that open-sourcing Canaan’s hardware and software was pivotal to decentralizing global hash power and mitigating 51% attack risks.
"The best way to defend against [51% attacks] was to rapidly distribute ASIC-based computing worldwide," Zhang noted.
This philosophy spurred industry giants like Bitmain and Intel to develop their own ASICs, cementing ASICs as the backbone of Bitcoin’s security.
Moore’s Law Meets Bitcoin: The Future of Chip Design
Semiconductor advancements have long followed Moore’s Law, but quantum effects at sub-2nm scales threaten to disrupt this trajectory. Zhang acknowledged flattening efficiency gains but highlighted innovative workarounds:
- New Transistor Technologies: Gate arrays and nanosheets with backside power delivery.
- Mixed-Signal Designs: Blending digital and analog implementations for optimized performance.
- DTCC Collaboration: Closer coordination between chip designers and foundries.
Canaan plans annual ASIC releases with >20% efficiency gains per generation, exemplified by its A15 AvalonMiner (18.5J/T efficiency).

Mining’s New Frontier: The Middle East and Sustainability
Middle East Expansion
Zhang identified the Middle East as a burgeoning hub for Bitcoin mining, citing progressive regulations and high-tech investments. Projects like Zero Two’s waste-heat desalination underscore the region’s innovative synergy with mining.
Sustainable Mining Trends
Criticism of mining’s environmental impact is waning as the sector embraces renewables:
- Heat Recapture: Boiling-water generation from mining operations.
- Hydropower Synergy: Mining stabilizes grid mismatches, shortening ROI periods for renewables.
"Bitcoin mining automatically balances environmentalism, economic efficiency, and development," Zhang stated.
Bitcoin and AI: Converging Energy Strategies
Zhang foresees collaboration between Bitcoin miners and AI data centers:
- Stranded Energy Utilization: Mining monetizes energy before AI demand peaks.
- Co-Location: Mining leverages AI facilities’ redundant power (25–30% capacity).
This symbiosis could redefine energy asset development for both industries.
