<br> When China announced on September 24 that it would ban all cryptocurrency activities, bitcoin fell less than 6 percent.The total value of all cryptocurrencies is now estimated at $2.5 trillion, and a single bitcoin trades for around $60,000 (up from a low of around $4,000 during the broader market crash in March of last year). How about trades that occur all inside the warehouse? Internationally, this emission output would exceed the total annualized greenhouse gas emission output of the Czech Republic and Qatar. The level variable GDP consists of Bitcoin miner’s profit rate and total cost, which reflects the accumulated productivity of 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 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. In this paper, we quantify the current and future carbon emission patterns of Bitcoin blockchain operation in China under different carbon policies<br>>
<br>> 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. In this work, we show that moving away information from Coin Viewer 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. Due to the proximity to manufacturers of specialized hardware and access to cheap electricity, majority of the mining process has been conducted in China as miners in the country account for more than 75% of the Bitcoin network’s hashing power, as shown in Fig. 1. As one of the largest energy consuming countries on the planet, China is a key signatory of the Paris Agreement18,19,20. Nevertheless, the rapid hardware development and fierce competition have significantly increased the capital expenditure for Bitcoin mining15; second, the Bitcoin mining activity and the constant-running mining hardware has led to large energy consumption volume. The mining hardware has evolved through several generations. 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 industr<br>p><br>p> Through scenario analysis, we find that some commonly implemented carbon emission policies, such as carbon taxation, are relatively ineffective for the Bitcoin industry. In addition, the maximized carbon emission per GDP of the Bitcoin industry would reach 10.77 kg/USD based on BBCE modeling. This paper uses the theory of carbon footprint to create a theoretical model for Bitcoin blockchain carbon emission assessment and policy evaluation11,12. In addition, since the SD-based model is focused on disequilibrium dynamics of the complex system9,10, 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. 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 country10.

By his calculations based on the current network characteristics, this should limit the amount of bandwidth used for gossip updates to about 12 MB per day, making it easier to use LN on slow devices (like single-board computers) and low-bandwidth network connections. As Bitcoin attracted considerable amount of attention in recent years, its underlying core mechanism, namely blockchain technology, has also quickly gained popularity. In recent years, the system dynamics (SD) based model is widely introduced for carbon emission flow estimation of a specific area or industry4,5. 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 2140. As a result, the Bitcoin market price increases periodically due to the halving mechanism of Bitcoin blockchain. Specifically, transactions packaged in the block are confirmed when the block is formally broadcasted to the Bitcoin blockchain. While this can be exploited for fee attacks, it is a bigger threat to pre-signed transactions protocol<br>p>
