Unlike dollar bills and coins, cryptocurrencies are not issued or backed by the U. The lack of a physical token to count and hold may confuse some. Rather, Bitcoin and other cryptocurrencies are a form of digital currency used in electronic payment transactions—no coins, paper money or banks are involved; there are zero to minimal transaction fees; transactions are fast and not bound by geography; and, similar to using cash, transactions are anonymous. Digital currencies are stored in digital wallets, which are software or apps installed by users on their computer or mobile device. Each digital wallet contains encrypted information, called public and private keys, that is used to send and receive the digital currency. Miners are awarded digital currency, like Bitcoin, Ripple, Dogecoin, and Litecoin, in exchange for verifying each transaction and adding it to the blockchain.

By investigating carbon emission flows of Bitcoin blockchain operation in China with a simulation-based Bitcoin blockchain carbon emission model, we find that without any policy interventions, the annual energy consumption of the Bitcoin blockchain in China is expected to peak in at Internationally, this emission output would exceed the total annualized greenhouse gas emission output of the Czech Republic and Qatar.

Domestically, it ranks in the top 10 among cities and 42 industrial sectors in China. In this work, we show that moving away from the current punitive carbon tax policy to a site regulation policy which induces changes in the energy consumption structure of the mining activities is more effective in limiting carbon emission of Bitcoin blockchain operation.

As Bitcoin attracted considerable amount of attention in recent years, its underlying core mechanism, namely blockchain technology, has also quickly gained popularity. Due to its key characteristics such as decentralization, auditability, and anonymity, blockchain is widely regarded as one of the most promising and attractive technologies for a variety of industries, such as supply chain finance, production operations management, logistics management, and the Internet of Things IoT 1 , 2 , 3.

Despite its promises and attractiveness, its first application in the actual operation of the Bitcoin network indicates that there exists a non-negligible energy and carbon emission drawback with the current consensus algorithm. Therefore, there is an urgent need to address this issue. In this paper, we quantify the current and future carbon emission patterns of Bitcoin blockchain operation in China under different carbon policies.

In recent years, the system dynamics SD based model is widely introduced for carbon emission flow estimation of a specific area or industry 4 , 5. In comparison to its counterparts, SD modeling has two main advantages in carbon emission flow assessment: first, by combining the feedback loops of stock and flow parameters, SD is able to capture and reproduce the endogenous dynamics of complex system elements, which enables the simulation and estimation of specific industry operations 6 , 7 , 8.

In addition, since the SD-based model is focused on disequilibrium dynamics of the complex system 9 , 10 , intended policies can be adjusted for scenario policy effectiveness evaluation. Consequently, based on system dynamics modeling, we develop the Bitcoin blockchain carbon emission model BBCE to assess the carbon emission flows of the Bitcoin network operation in China under different scenarios.

This paper uses the theory of carbon footprint to create a theoretical model for Bitcoin blockchain carbon emission assessment and policy evaluation 11 , First, we establish the system boundary and feedback loops for the Bitcoin blockchain carbon emission system, which serve as the theoretical framework to investigate the carbon emission mechanism of the Bitcoin blockchain.

The BBCE model consists of three interacting subsystems: Bitcoin blockchain mining and transaction subsystem, Bitcoin blockchain energy consumption subsystem, and Bitcoin blockchain carbon emission subsystem. Specifically, transactions packaged in the block are confirmed when the block is formally broadcasted to the Bitcoin blockchain.

To increase the probability of mining a new block and getting rewarded, mining hardware will be updated continuously and invested by network participants for a higher hash rate, which would cause the overall hash rate of the whole network to rise. The network mining power is determined by two factors: first, the network hash rate hashes computed per second positively accounts for the mining power increase in the Bitcoin blockchain when high hash rate miners are mining; second, power usage efficiency PUE is introduced to illustrate the energy consumption efficiency of Bitcoin blockchain as suggested by Stoll The network energy cost of the Bitcoin mining process is determined by the network energy consumption and average electricity price, which further influences the dynamic behavior of Bitcoin miners.

The BBCE model collects the carbon footprint of Bitcoin miners in both coal-based energy and hydro-based energy regions to formulate the overall carbon emission flows of the whole Bitcoin industry in China. It also serves as an auxiliary factor to generate the carbon emission per GDP in our model, which provides guidance for policy makers in implementing the punitive carbon taxation on the Bitcoin mining industry.

Bitcoin blockchain reward halving occurs every four years, which means that the reward of broadcasting a new block in Bitcoin blockchain will be zero in As a result, the Bitcoin market price increases periodically due to the halving mechanism of Bitcoin blockchain. Miners will gradually stop mining in China or relocate to elsewhere when the mining profit turns negative in our BBCE simulation. We find that the annualized energy consumption of the Bitcoin industry in China will peak in at This exceeds the total energy consumption level of Italy and Saudi Arabia and ranks 12 th among all countries in Correspondingly, the carbon emission flows of the Bitcoin operation would peak at Internationally, this emission output surpasses the total greenhouse gas emission output of the Czech Republic and Qatar in reported by cia.

Domestically, the emission output of the Bitcoin mining industry would rank in the top 10 among prefecture-level cities and 42 major industrial sectors in China, accounting for approximately 5.

In addition, the maximized carbon emission per GDP of the Bitcoin industry would reach Through scenario analysis, we find that some commonly implemented carbon emission policies, such as carbon taxation, are relatively ineffective for the Bitcoin industry. On the contrary, site regulation policies for Bitcoin miners which induce changes in the energy consumption structure of the mining activities are able to provide effective negative feedbacks for the carbon emission of Bitcoin blockchain operation.

Although the Proof-of-Work PoW consensus algorithm has enabled Bitcoin blockchain to operate in a relatively stable manner, several unexpected behaviors of the Bitcoin blockchain have been detected: first, the attractive financial incentive of Bitcoin mining has caused an arms race in dedicated mining hardware The mining hardware has evolved through several generations. Nevertheless, the rapid hardware development and fierce competition have significantly increased the capital expenditure for Bitcoin mining 15 ; second, the Bitcoin mining activity and the constant-running mining hardware has led to large energy consumption volume.

Previous literature has estimated that the Bitcoin blockchain could consume as much energy per year as a small to medium-sized country such as Denmark, Ireland, or Bangladesh 16 ; finally, the large energy consumption of the Bitcoin blockchain has created considerable carbon emissions see Supplementary Fig.

It is estimated that between the period of January 1 st , and June 30 th , , up to 13 million metric tons of CO 2 emissions can be attributed to the Bitcoin blockchain Although the estimate ranges vary considerably, they have indicated that energy consumption of network and its corresponding environmental impacts have become a non-negligible issue.

The growing energy consumption and the environmental impacts of the Bitcoin blockchain have posed problems for many countries, especially for China. As one of the largest energy consuming countries on the planet, China is a key signatory of the Paris Agreement 18 , 19 , However, without appropriate interventions and feasible policies, the intensive Bitcoin blockchain operation in China can quickly grow as a threat that could potentially undermine the emission reduction effort taken place in the country Some rural areas in China are considered as the ideal destination for Bitcoin mining mainly due to the cheaper electricity price and large undeveloped land for pool construction.

Suggested by the previous work 21 and the subsystems of our proposed BBCE model, we consider three main Bitcoin policies conducted at different stages of the Bitcoin mining industry, which then formulates the four scenario assessments for Bitcoin blockchain carbon emission flows in Table 1. In detail, Benchmark BM scenario is a baseline and current scenario of each policy factor, which suggests that the Bitcoin industry continues to operate under minimal policy intervention. Moreover, the punitive carbon tax will be imposed if the carbon emission per GDP of the Bitcoin industry is greater than 2.

In the other three scenarios, policies on different Bitcoin mining procedures are adjusted due to energy saving and emission reduction concerns.

Specifically, in the Bitcoin mining and transaction subsystem, market access standard for efficiency is doubled, i. In the carbon tax CT scenario, carbon tax is increased to two-times the initial value to enforce more strict punishment for high carbon emission behaviors of Bitcoin blockchain.

Utilizing the above scenarios, carbon emission flows and energy consumptions of Bitcoin blockchain are assessed, the carbon and energy reduction effectiveness of different policies are evaluated in BBCE simulations from the period of — Without any policy interventions, the carbon emission pattern of the Bitcoin blockchain will become a non-negligible barrier against the sustainability efforts of China.

The peak annual energy consumption and carbon emission of the Bitcoin blockchain in China are expected to exceed those of some developed countries such as Italy, the Netherlands, Spain, and Czech Republic. Figure 2 reports the estimated annualized energy consumption and carbon emission flows of Bitcoin blockchain in China. As the baseline assessment under minimal policy intervention, the Benchmark scenario simulates the natural operation results of the Bitcoin blockchain.

In the BM scenario, the annual energy consumption of Bitcoin blockchain in China will gradually grow and eventually peak in , at This suggests that Bitcoin industry operation would follow an energy intensive pattern. In fact, energy consumed by Chinese Bitcoin blockchain in will exceed the energy consumption level of Italy and Saudi Arabia in , ranking it 12th among all the countries.

Regarding the carbon tax scenario, the highest energy demand of the Bitcoin industry slightly decreases due to carbon emission penalties, at However, the results of the market access and site regulation scenarios indicate that the total energy consumption of the Bitcoin industry will reach Estimated annualized energy consumption a and carbon emission flows b of Bitcoin operation in China are generated through monthly simulation results of BBCE modeling from to The blue, red, yellow, and green bars in a and b indicate the annual energy consumption and carbon emission flows of Chinese Bitcoin industry in benchmark, site regulation, market access, and carbon tax scenario, respectively.

It is clear that the carbon emission behavior of the Bitcoin industry is consistent with the Bitcoin blockchain energy consumption intensity.

In the BM scenario, annual carbon emission of the Bitcoin industry is expected to reach its maximum in , at At the international level, the estimated Bitcoin carbon emission in China exceeds the total greenhouse emission of the Czech Republic and Qatar in , ranking it 36 th worldwide. At the domestic level, the emission output of the Bitcoin mining industry would rank in the top 10 among Chinese prefecture-level cities and 42 major industrial sectors.

In comparison, the carbon emissions generated by Bitcoin blockchain experienced a significant reduction in SR and CT scenarios, which illustrate the positive impact of these carbon-related policies. On the contrary, the MA scenario witnesses a considerable increase of Bitcoin carbon emission to Based on the scenario results of the BBCE model, the Benchmark scenario indicates that the energy consumed and the carbon emissions generated by Bitcoin industry operation are simulated to grow continuously as long as mining Bitcoin maintains its profitability in China.

This is mainly due to the positive feedback loop of the PoW competitive mechanism, which requires advanced and high energy-consuming mining hardware for Bitcoin miners in order to increase the probability of earning block rewards. In addition, the flows and long-term trend of carbon emission simulated by the proposed system dynamics model are consistent with several previous estimations 10 , 13 , which are devoted to precisely estimate the carbon footprint of Bitcoin blockchain. The Paris Agreement is a worldwide agreement committed to limit the increase of global average temperature 22 , However, according to the simulation results of the BBCE model, we find that the carbon emission pattern of Bitcoin blockchain will become a potential barrier against the emission reduction target of China.

As shown in Fig. In particular, it would account for approximately 5. The peak carbon emission per GDP of Bitcoin industry is expected to sit at In addition, in the current national economy and carbon emission accounting of China, the operation of the Bitcoin blockchain is not listed as an independent department for carbon emissions and productivity calculation. This adds difficulty for policy makers to monitor the actual behaviors of the Bitcoin industry and design well-directed policies.

In fact, the energy consumption per transaction of Bitcoin network is larger than numerous mainstream financial transaction channels To address this issue, we suggest policy makers to set up separated accounts for the Bitcoin industry in order to better manage and control its carbon emission behaviors in China. In Fig. Annual energy consumption and ranking by countries a are obtained from cia. The carbon emission by Chinese cities c and industrial sectors d are obtained from China Emission Accounts and Datasets www.

Due to the unreleased or missing data in some database, the above energy consumption and carbon emission data are obtained for level. Policies that induce changes in the energy consumption structure of the mining activities may be more effective than intuitive punitive measures in limiting the total amount of energy consumption and carbon emission in the Bitcoin blockchain operation. Figure 4 presents the values of key parameters simulated by BBCE model. The carbon emission per GDP of the BM scenario in China is larger than that of all other scenarios throughout the whole simulation period, reaching a maximum of However, we find that the policy effectiveness under the MA and CT scenario is rather limited on carbon emission intensity reduction, i.

Overall, the carbon emission per GDP of the Bitcoin industry far exceeds the average industrial carbon intensity of China, which indicates that Bitcoin blockchain operation is a highly carbon-intense industry.

Based on the regressed parameters of the BBCE model, the whole sample timesteps of network carbon emission assessment cover the period from January to January However, it is important to note that the entire relocation process does not occur immediately. Miners with higher sunk costs tend to stay in operation longer than those with lower sunk costs, hoping to eventually make a profit again.

Consequently, the overall energy consumption associated with Bitcoin mining remains positive until the end of , at which time almost all miners would have relocated elsewhere. Correspondingly, the network hash rate is computed to reach EH per second in the BM scenario and the miner total cost to reach a maximum of million dollars. Comparing the scenario results for the three policies, the profitability of mining Bitcoin in China is expected to deteriorate more quickly in the CT scenario.

In the hype of bitcoin and cryptocurrency was high, and so were the profits to be made if you knew what you were doing. Millionaires were made. But in views changed when the market crash showed that cryptocurrency was just as fallible as real coins. Only the die-hard fans stuck with the currency and the persistent few hackers who still saw the opportunity to use the currency for ransom attacks.

Cryptocurrency is attracting the attention of many disciplines.

But, as with most things Bitcoin, this interpretation is based more on hope than fact. Bitcoin has failed to live up to the hype that it would democratize finance by enabling cheap, instantaneous, and secure payments that could be conducted without having to rely on stodgy old financial institutions like banks and credit card companies. Bitcoin has failed to meet this vision due to its excessive price volatility, slow transaction processing, difficult user experience e. Some have even questioned whether bitcoin has any social value at all. Rather than being a viable currency at scale, Bitcoin is and will remain a speculative asset, in a class with gold, tulips, and Beanie Babies.

All the industry, if not the entire world is talking about crypto-mining, and the value of Bitcoins. One of the benefactors of this explosive commodity market bubble has been the suppliers of add-in boards AIBs and subsequently the purveyors of GPUs. Motherboard and power supply unit PSU suppliers have also benefited.
