From the Bitcoin halving in Could to the continuing worth rally at present, bitcoin has actually seen its justifiable share of ups and downs in 2020. At the same time as the value of bitcoin units new highs above these of 2017, observers have remained cautious, fearing that this will likely very properly be a bitcoin bubble 2.0. Nonetheless, pointing to a maturing market the place curiosity in digital belongings is rising amongst institutional traders, Bitcoin advocates have argued that this rally isn’t just 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 ranges 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 numerous jurisdictions stretching from lesser-known provinces in China to Kazakhstan and even Malaysia.
This put up is a part of CoinDesk’s 2020 12 months in Assessment – a set of op-eds, essays and interviews in regards to the 12 months 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 business 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 12 months, 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 lately, 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 international locations such because the U.S., Russia and Kazakhstan are beginning to catch up.
With the intention to carve out house and thrive within the bitcoin mining house, these new contenders want to think about a large number of things, specifically: aggressive vitality costs or various vitality sources, engaging actual property costs and a authorities supportive of digital belongings.
Mining-friendly Kazakhstan, as an example, has seen vital development in bitcoin mining actions, holding over 6.17% of the entire bitcoin mining hashrate. That is largely attributed to a tax-friendly authorities the place crypto mining won’t be taxed till the mined belongings are exchanged for fiat cash. Then there may be the legalization of mining, which noticed a latest invoice accepted by the Kazakh Senate and signed into legislation earlier in June. The low electrical energy prices solely function icing on prime.
This strategy has actually paid off, with investments in native crypto mining operations anticipated to double by the tip of 2020 and an extra $738 million anticipated to pour in over the following three years.
China’s bitcoin mining crown won’t be so simply displaced
As we glance in the direction of 2021, bitcoin mining will proceed to maneuver in a optimistic route and see continued momentum. For 2 years now, markets throughout the Commonwealth of Unbiased States (CIS), Europe and North America have grown. This development is barely going to be extra outstanding as miners look to new jurisdictions to keep away from regulatory crackdowns whereas trying to find lower-cost electrical energy.
In Europe and North America, plans for opening mining services might have been delayed because of the COVID-19 pandemic. However with the gradual restoration of the bitcoin market and the chance of a coronavirus vaccine in 2021, we may even see a rebound within the demand for mining. The implications of a brand new Biden administration on the therapy of cryptocurrencies, alternatively, nonetheless stay unclear.
Regardless of new markets looming on the horizon, China’s bitcoin mining crown won’t be so simply displaced. The Chinese language authorities has known as to speed up the event of blockchain expertise 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 at present’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 continually sustain with the business’s fast-growing calls for. If not, miners will not be capable to compete primarily based on gear, however as a substitute, look elsewhere – whether or not it’s in various sources of vitality or different types of consensus protocols – to additional set up a aggressive edge and earn most income.
For the reason that 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 higher effectivity features. Nonetheless, these enhancements have been plateauing with every new iteration. And regardless of bitcoin mining being the final 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 relation to the following technological innovation, a lot has been mentioned about the usage of quantum computing. Touted as the following computing frontier, quantum tech might doubtlessly crack Bitcoin’s safety and successfully rendering Bitcoin’s cryptographic keys insecure. When this occurs, a comfortable 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.
Nonetheless, it’s early days for quantum computing, and going into 2021 ASICs will nonetheless be the cornerstone of bitcoin mining. I imagine bitcoin miners shall be ready one other few years earlier than the arrival of the following groundbreaking expertise.
Sustainability not for sustainability’s sake
As mining machines get more and more highly effective, so, too, will vitality consumption enhance.
Areas like China’s Xinjiang and Internal Mongolia have traditionally been reliant on coal vitality to supply crypto mining corporations with decrease vitality costs. China is searching for to handle air pollution on a broader degree, lately stating its ambitions for a “green revolution” to grow to be carbon-neutral by 2060. Because of this mining with non-renewable sources of vitality corresponding to coal will grow to be 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 crops within the Sichuan province as their supply of renewable vitality. However when you think about that hydropower is barely accessible through the moist season in China, six months of the 12 months, it’s no shock that bitcoin miners have solid their eyes to extra progressive and sustainable sources of vitality throughout novel jurisdictions for renewable or surplus vitality.
As 2020 involves an in depth, the way forward for bitcoin mining appears vibrant. 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 are going to do properly to plan strategically for the long-term and never solely contemplate short-term wins – whether or not it’s in tech or profitability – focusing as a substitute on the whole integration of economic, sustainability and environmental targets.
