It’s no secret that the bitcoin mining trade is being battle-tested within the wake of the fourth halving. Hash worth (income per terrahash) has reached historic lows as bitcoin’s block subsidy has been slashed. In the meantime, the post-halving mempool frenzy has waned, including gasoline to the hearth on already strained mining operators.
Nangeng Zhang, Founder and CEO of Singapore-based Canaan Inc, the creator of the primary bitcoin mining application-specific built-in circuit (ASIC), sat down with Bitcoin Journal for the agency’s first-ever interview with a North American media outlet to weigh in on the state of the trade. Zhang commented on the origins of bitcoin mining and supplied his perspective on the panorama for chip design in addition to tendencies in environmental sustainability.
Zhang additionally recognized burgeoning alternatives for Bitcoin within the Center East, in addition to the convergence between the bitcoin and synthetic intelligence (AI) industries.

The Open Supply Core of Bitcoin Mining
Canaan, based in 2013, revolutionized mining with the launch of its first AvalonMiner ASIC machine – marking a turning level in computational effectivity for these securing the Bitcoin community. Because the trade moved away from conventional GPU and CPU-based hashing, the embracing and commodification of specialised ASIC {hardware} noticed commercial-scale mining operations start to take form.
This step-change by Canaan didn’t happen in a vacuum, however led to the ever-present proliferation of ASIC-based hashing after the agency open sourced each its Avalon {hardware} and administration software program. Zhang famous that this embrace of the open supply motion within the early days of bitcoin was “not a call” however fairly “a requirement for anybody who desires to get entangled within the blockchain group” and a method “to decentralize computing energy everywhere in the world.”
“One of the best ways to defend towards [51% attacks], was to quickly distribute ASIC-based computing to customers worldwide”. In Zhang’s estimation, the danger of a 51% assault has tremendously diminished as a result of democratization and wide-scale deployment of ASICs. The open supply nature of Canaan’s chip design has since led main companies together with China-based Bitmain and computing stalwart Intel to create their very own ASIC machines.
Operating (Bitcoin) Up Towards Moore’s Legislation: Developments In Chip Effectivity
Canaan, as a designer of ASIC chips, has been a beneficiary of the growth in semiconductor manufacturing over the previous decade-plus. On the coronary heart of this progress lies Moore’s Legislation – an commentary that computational effectivity has roughly doubled each 2 years. In the present day, companies together with Taiwan Semiconductor (TSMC), Samsung (SSLF), and Semiconductor Manufacturing Worldwide Company (SMIC) are ramping up in the direction of 3 nanometer chip manufacturing on this quest for optimization.
Nonetheless, the transfer towards smaller and smaller scale architectures for semiconductors isn’t with out challenges. Rising transistor density on smaller and smaller chips, specifically, sub-2 nanometer scales, invokes quantum, fairly than classical, results. This regime shift results in transistor malfunction and a possible divergence with Moore’s Legislation.
The query has now grow to be: will Moore’s Legislation maintain, or is the classical computational growth changing into a quantum bust?
Zhang, confronted with the query of those elementary constraints on ASIC computation, acknowledged “up to now, once we boosted efficiency, the associated fee per terrahash went down. In the present day, this curve has flattened. This means that technological developments are coming into a brand new part.”
“We’re certainly seeing a slowdown within the development of course of nodes, selling us to undertake new transistor applied sciences like GA (gate array) or nanosheet applied sciences together with bottom energy supply. This isn’t simply making the floor smaller, however altering the construction of the circuit [itself].”
“Bitcoin computing appeals to a purely digital logic, however as we speak, we’re shifting nearer to a blended sign design for analog implementations.” This enhance in complexity, based on Zhang, suggests the necessity for “design expertise co-optimization (DTCC)” between designers similar to Canaan and the foundries that produce the chips themselves.
Regardless of these challenges, Zhang believes that AISC effectivity is “nonetheless on the rise for the following 3-5 years” and the corporate plans to launch not less than 1 new product per yr with “over 20% effectivity features” per era.
This effectivity acquire was on show on the Bitcoin Asia convention in Hong Kong on Could ninth, the place Canaan launched its next-generation A15 AvalonMiner, boasting an 18.5J/T effectivity compared to the ~20J/T afforded by the earlier A14 mannequin. Zhang famous the A15 as being significantly optimized for variable environmental situations.
Particularly, Canaan has enabled overclocking capabilities within the A15, and Zhang poked enjoyable on the widespread chorus from consumers who typically comment: “‘oh you may get additional efficiency without cost?!’” Sadly that’s not the case, based on Zhang, however the added capabilities promise to create further operational flexibility for patrons of the A15.
Decentralizing Computation: A Look To The Center East
Now, greater than ever, miners are looking out for effectivity features to… *drumroll*… scale back their prices and enhance income. That is, in fact, par for the course, however miners are turning to new applied sciences and geographies of their quest for affordable energy.
Zhang famous a strategic shift on the a part of Canaan to satisfy this transformation available in the market, emphasizing the agency’s latest transfer to accomplice with mining companies within the Center East area. “[The Middle East] is raring to put money into high-tech industries. These nations are significantly welcoming to Bitcoin and cryptocurrency. The Center East holds nice promise to grow to be a vital digital hub.”
On the subject of regulation within the Center East area, Zhang famous that the area has “rapidly superior in establishing complimentary regulatory frameworks for mining”. It follows that companies like Zero Two – backed by Abu Dhabi’s sovereign wealth fund – have made important strides to combine bitcoin mining and its waste warmth for the aim of saltwater desalination.
Warmth Verify: Developments In Mining Sustainability
Since Canaan’s IPO on the NASDAQ in 2019, the bitcoin market has been on fireplace, and together with it, bitcoin mining firms. Publicly traded megaminers like Marathon Digital Holdings Inc (NASDAQ: MARA) and Riot Platforms (NASDAQ: RIOT) turned family names through the 2020-2022 bull market upon bitcoin’s arrival to the mainstream.
However, with the elevated visibility, additionally got here elevated scrutiny from environmental organizations, notably the Ripple-funded and ill-conceived Change the Code marketing campaign led by Greenpeace USA.
When requested about environmental criticisms of mining, Zhang appeared unphased, welcoming dialogue of sustainability within the mining sector. “Perceptions of bitcoin mining as environmentally unfriendly are altering… bitcoin mining may help to develop renewable power industries.”
Particularly, the Canaan CEO praised warmth recapture as maybe the most important development but to play out in each residential and business functions. “Mining warmth restoration merchandise have began this yr. I feel in just a few years, I consider folks will see many very spectacular merchandise that make the most of warmth from mining. In the present day, we are able to generate near-boiling water from mining operations.” This development, he believes, underlies mining’s sustainable attributes and a basic development in the direction of warmth monetization in mining as a complete.
Zhang additionally emphasised the hydropower trade, whose energy typically suffers from a supply-demand mismatch, as a key space the place mining may supercharge renewable deployment.
In lieu of battery storage, Zhang posited that “[bitcoin mining] can enable these services to function at full capability more often than not. This may scale back the payback interval to about 5 to 10 years – which means the identical quantity of capital can develop twice as many hydro-stations in the identical timeframe… the identical precept applies to different renewable power assets like photo voltaic and wind power pushed purely by financial elements.”
He believes that mining will proceed its development towards low-carbon power assets and expressed optimism that the market dynamic driving the pursuit of low-cost power exhibits that “mining can mechanically stability between environmentalism, financial effectivity and growth.”
AI and Bitcoin Convergence: Growing and Scaling Power Belongings
Usually, Bitcoin miners have been pioneers within the energy markets, flocking to the place energy is ample, and demand is low. The symbiotic relationship between underdeveloped power assets, and the inherently versatile and cell community of bitcoin miners, has pushed ASIC-based computation to develop assets on the sting of the grid. However, based on Zhang, this isn’t the top of the story.
He sees a brand new relationship forming between AI knowledge facilities and bitcoin miners every trying to find the lowest-cost power inputs. Zhang made be aware of “main gamers” and “early movers” which have begun to appreciate the potential integration between bitcoin mining and AI computation.
“On this context, bitcoin mining can function an preliminary occupant of this [stranded] power, [generating] financial advantages earlier than AI computing energy totally comes on-line. That is what we now have seen up to now 6 months.”
Zhang additionally foresees co-location of AI high-performance knowledge facilities and bitcoin mining even after AI services are up and operating: “Given the redundancy necessities for large-scale AI computing facilities (25-30%) of energy redundancy… bitcoin mining can use the redundant energy and shut off when [AI comes online].”
Conclusion
The zero-sum mining trade, as at all times, continues to be its personal worst enemy. Coupled with the fourth halving, discount in margins, and the following wave of ASIC effectivity, it could be honest to say that gleaning a revenue from mining could possibly be as simple as squeezing blood from a (digital) rock.
However, on the margin, constructive tendencies are happening within the trade – and the Canaan CEO sees alternatives abound for enterprising mining and ASIC companies keen to blaze a path on the power and synthetic intelligence frontiers.
