Bitcoin mining leaves a footprint on half of the Earth’s surface: Nature

Bitcoin mining has experienced exponential growth and distribution in recent months, with more than 40% of the Earth’s surface located, according to the results of a scientific study conducted by researchers from the journal Nature.

According to the research, it is called Spatial Analysis of Global Bitcoin MiningAnd the Mining activity has been detected in more than 6000 geographical points in 139 countries and regions of the world. In more detail, 44.3% of the surface of our planet already has a Bitcoin mining footprint, as evidence of its increasing expansion.

The thing Nature highlights is that mining doesn’t discriminate on location. In fact, they explained that unlike already known points, such as China, the United States or Iceland, Mining has been revealed in unexpected places, such as Tahiti in French Polynesia or Malawi in Southeast Africa.

In addition, if you look closely at the attached map above, it is possible to see significant mining activity in Latin America, Especially in Venezuela and Brazil, where there are many green dots indicating equipment detection ASIC From mining on foot.

tendency to focus

Nature highlights that mining activity, which is widely distributed, is consistent with the principles of the decentralized nature of the blockchain. however, It indicates that there is a “strong trend towards spatial concentration” of minersespecially in places where energy is plentiful and cheap.

This phenomenon, as they called it, “increases the potential risk of attack by 51% and makes the entire network more vulnerable due to regulatory changes, disasters or other restrictions in specific locations.”


What Nature says refers to the United States or China, the two countries where there is more mining and where more than 50% of the computing power (the hash rate) of Bitcoin is concentrated.

But launching a 51% attack is not that easy. Therefore, more than half of the miners must agree to launch the attack and in the US, although there is a majority of the hash, This is distributed to companies and farms that hardly join forces to damage the source of their money.

And if not, To launch a 51% attack, it would be necessary to build a sufficient mechanism to beat the current mark, It would cost billions of dollars to achieve, not counting energy prices, which no one is likely to own.

international mark

Nature stresses that based on the analysis and study conducted by its researchers, the best way to regulate bitcoin mining is through Building a global framework in the short term, motivating operators to mine where there is abundant renewable energy and ability Electricity surplus.

These can be places in Latin America, where the activity can be profitable, having conditions close to nature, It can enhance the enormity of mining.

Venezuela, for example, has frequent electricity surpluses, which can be used to improve the national electrical system, as Bitcoin miners suggested earlier this year.

Nature, through its research, does nothing more than recognize the growth of Bitcoin mining, an activity that does not seem to give up, although it is in crisis (due to falling prices), on the contrary, What it does is keep its constant expansion.
