China has long been the dominant player in the bitcoin mining market, controlling more than 70% of the global hashrate. However, with the introduction of strict regulations and bans on cryptocurrency mining in 2021, China's influence on the mining complexity of BTC has undergone significant changes. In this article, we look at how China's actions are reflected in the mining complexity of bitcoin, what consequences this has for the entire network, and how the redistribution of mining capacity around the world changes the mining landscape.
1. What is bitcoin mining complexity?
Bitcoin mining complexity (or mining complexity) is a parameter that determines how difficult it is to find a new block on the network. It is automatically adjusted every 2016 blocks (approximately every two weeks) and depends on the total network hash rate. If the hash rate grows (that is, the computational power of mining increases), the complexity increases to maintain a stable interval between blocks. If the hashrate drops, the complexity decreases.
Mining complexity plays a key role in the security of the network, as it prevents possible attacks and helps maintain the stability of the bitcoin network. Therefore, any changes in the hash (and therefore in mining complexity) have a significant impact on the market.
2. How did China influence bitcoin's mining complexity until 2021?
Until 2021, China was the world leader in bitcoin mining. The largest mining companies and farms were located in the country, which allowed Chinese operators to control most of the network's hashrate. China's influence on mining complexity was obvious: since China provided a significant amount of computing power, the complexity of bitcoin mining remained high.
China's dominant position in mining also meant that any jump or drop in the country's hashrate had a major impact on global mining complexity. For example, when Chinese mining companies increased their capacity, the complexity of mining automatically increased, creating a more competitive environment for bitcoin mining.
3. China mining bans: Impact on hashrate and complexity
In 2021, the Chinese government implemented a complete ban on cryptocurrency mining, which led to the massive closure of mining farms throughout the country. The decision caused a sharp reduction in the bitcoin network's hashrate as Chinese mining companies controlled a huge share of the global hashrate.
3.1 Sharp decline in hashrate
After China's mining ban, bitcoin's hashrate fell 40-50%, the largest drop in the history of cryptocurrencies. The decrease in the hash rate led to a decrease in the total computing power of the network, and in order to maintain stable time between blocks, mining complexity began to decrease.
3.2 Capacity reallocation
After the ban on mining in China, many Chinese mining companies were forced to look for new locations for their farms, moving to other countries such as the United States, Kazakhstan, Russia, Canada and others. This redistribution of capacity led to a change in the distribution of the hashrate around the world, with an increase in capacity in new regions. However, the process of moving and installing new equipment took some time, and the hashrate did not recover instantly.
3.3 Complexity Adjustment
A decrease in the hashrate as a result of China's ban automatically led to a decrease in the mining complexity of bitcoin. This phenomenon, called "automatic complexity adjustment," is an integral part of bitcoin's blockchain mechanism, allowing the network to adapt to changes in computing power.
However, despite the fact that the complexity has decreased, it still remained high compared to those times when Chinese farms occupied a dominant position. The redistribution of capacity and adaptation of new mining farms took time, but eventually the difficulty began to recover as the hashrate increased in other countries.
4. Implications for network security and global mining
4.1 Decentralization of Mining
One of the positive consequences of China's bans was a more even distribution of mining capacity around the world. This has contributed to improved decentralization of the bitcoin network, as mining power is now distributed across multiple countries rather than concentrated in the same region.
Decentralization of mining contributes to improving network security, as reducing the concentration of power in one place reduces the risks associated with possible attacks on the network, for example, attacks of 51%.
4.2 Increasing Market Resilience
The redistribution of capacity and adaptation of mining farms in new countries also increased the stability of the bitcoin market. China was too big, and its exit from the mining ecosystem caused significant changes in the dynamics of hashrate and mining complexity. Now, given the more even distribution of capacity, the market has become less influenced by one region or state.
5. Conclusion
Banned Chinese measures against bitcoin mining had a significant impact on the mining complexity of the network. A sharp reduction in the hashrate after the ban on mining in China led to a decrease in complexity, which made it easier for miners in other countries to adapt to new conditions. However, this process also contributed to the decentralization of mining, improving the security of the network and making it more resistant to external risks. In the future, China, despite the ban on mining, will continue to influence the global cryptocurrency market, but a more even distribution of capacity and increased decentralization will create a more stable and secure ecosystem for bitcoin mining.
