From the Bitcoin halving in Might to the continuing worth rally as we speak, bitcoin has actually seen its fair proportion of ups and downs in 2020. Whilst the value of bitcoin units new highs above these of 2017, observers have remained cautious, fearing that this will likely very nicely be a bitcoin bubble 2.0. Nevertheless, pointing to a maturing market the place curiosity in digital property is rising amongst institutional buyers, Bitcoin advocates have argued that this rally is not only one other speculative frenzy. With such renewed optimism, one can solely hope that this time, historical past doesn’t repeat itself.
On the similar time, with miner revenues hitting pre-halving levels for the primary time this November, a lot has modified because the genesis block got here into being. Now not restricted to a community of unbiased miners, we now see staggering operations at scale, in various jurisdictions stretching from lesser-known provinces in China to Kazakhstan and even Malaysia.
This submit is a part of CoinDesk’s 2020 12 months in Assessment – a group of op-eds, essays and interviews concerning the yr in crypto and past. Nangeng “NG” Zhang is the founder, chairman and CEO of Canaan, a number one supplier of supercomputing options.
Regardless of this development, the burgeoning mining trade faces existential dangers. And never solely those associated to the long-term sustainability of bitcoin mining after the final block is mined in 2140.
New yr, new markets
With its cheap electrical energy, low manufacturing prices and available labor, China has lengthy dominated the bitcoin mining sector. But, the middle of gravity has began to shift in recent times, largely as a result of emergence of mining swimming pools in different elements of the world. Regardless of China nonetheless holding greater than two-thirds of the worldwide hashrate distribution nations such because the U.S., Russia and Kazakhstan are beginning to catch up.
With a view to carve out house and thrive within the bitcoin mining house, these new contenders want to think about a mess of things, particularly: aggressive power costs or different power sources, enticing actual property costs and a authorities supportive of digital property.
Mining-friendly Kazakhstan, for example, has seen important development in bitcoin mining actions, holding over 6.17% of the overall bitcoin mining hashrate. That is largely attributed to a tax-friendly government the place crypto mining is not going to be taxed till the mined property are exchanged for fiat cash. Then there may be the legalization of mining, which noticed a current invoice permitted by the Kazakh Senate and signed into legislation earlier in June. The low electrical energy prices solely function icing on prime.
This method has actually paid off, with investments in native crypto mining operations anticipated to double by the top of 2020 and a further $738 million anticipated to pour in over the following three years.
As we look towards 2021, bitcoin mining will continue to move in a positive direction and see continued momentum. For two years now, markets across the Commonwealth of Independent States (CIS), Europe and North America have grown. This trend is only going to be more prominent as miners look to new jurisdictions to avoid regulatory crackdowns while searching for lower-cost electricity.
In Europe and North America, plans for opening mining facilities may have been delayed as a result of the COVID-19 pandemic. But with the gradual recovery of the bitcoin market and the likelihood of a coronavirus vaccine in 2021, we may see a rebound in the demand for mining. The implications of a new Biden administration on the remedy of cryptocurrencies, alternatively, nonetheless stay unclear.
Regardless of new markets looming on the horizon, China’s bitcoin mining crown is not going to be so simply displaced. The Chinese language authorities has known as to accelerate the development of blockchain technology and monetary incentives to advance in renewable energy-powered crypto mining.
Bitcoin mining has actually come a great distance because the early CPU days of Nakamoto’s genesis block. From preliminary improvements like GPUs and FPGAs to the beginning of as we speak’s ASICs, miners proceed to hunt out the quickest, strongest and cost-efficient machines.
The present aggressive state of bitcoin mining implies that technological innovation must continuously sustain with the trade’s fast-growing calls for. If not, miners will not have the ability to compete based mostly on tools, however as a substitute, look elsewhere – whether or not it’s in different sources of power or different types of consensus protocols – to additional set up a aggressive edge and earn most income.
Because the ASICs revolution, a lot of the technological progress in bitcoin mining has come from the discount of chip sizes and better hashrates to supply miners with larger effectivity positive aspects. Nevertheless, these enhancements have been plateauing with every new iteration. And regardless of bitcoin mining being the last word manifestation of proof-of-work (PoW), questions over PoW’s long-term viability have been raised. Ethereum 2.0’s proof-of-stake (PoS) consensus is arguably a extra sustainable and environmentally-friendly mannequin.

In the case of the following technological innovation, a lot has been stated about the usage of quantum computing. Touted as the following computing frontier, quantum tech could doubtlessly crack Bitcoin’s security and successfully rendering Bitcoin’s cryptographic keys insecure. When this occurs, a mushy fork could be prone to happen, enabling the Bitcoin protocol to run on quantum-resistant algorithms and doubtlessly even be operated by nodes that run on quantum computer systems.
Nevertheless, it’s early days for quantum computing, and going into 2021 ASICs will nonetheless be the cornerstone of bitcoin mining. I imagine bitcoin miners can be ready one other few years earlier than the arrival of the following groundbreaking know-how.
Sustainability not for sustainability’s sake
As mining machines get more and more highly effective, so, too, will power consumption improve.
Areas like China’s Xinjiang and Inside Mongolia have traditionally been reliant on coal power to supply crypto mining firms with decrease power costs. China is in search of to deal with air pollution on a broader degree, just lately stating its ambitions for a “green revolution” to turn into carbon-neutral by 2060. Because of this mining with non-renewable sources of power corresponding to coal will turn into more and more cost-inefficient for China-based miners.

To additional compound issues, bitcoin miners have historically relied on a budget electrical energy powered by hydroelectric vegetation within the Sichuan province as their supply of renewable power. However when you think about that hydropower is simply accessible in the course of the moist season in China, six months of the yr, it’s no shock that bitcoin miners have forged their eyes to extra revolutionary and sustainable sources of power throughout novel jurisdictions for renewable or surplus power.
As 2020 involves an in depth, the way forward for bitcoin mining appears to be like vivid. Simply as we recovered from the final bitcoin bubble popping, 2021 will see a brighter outlook because the fourth industrial revolution performs out.
In reimagining a mining ecosystem that’s each sustainable and viable, we’ll do nicely to plan strategically for the long-term and never solely think about short-term wins – whether or not it’s in tech or profitability – focusing as a substitute on the entire integration of business, sustainability and environmental targets.
