Public officials participating in virtual currency mining will be transferred to the supervisory organ. What are the hazards of mining?

What are the hazards of virtual currency mining? Recently, Alex De Vries, a principal researcher, published an analysis report entitled "Sustainable energy cannot solve the sustainability problem". He believes that the power consumption cost of MTD not only offsets renewable energy, but also fails to realize other environmental costs brought by mining. How much damage does the bitcoin mine have?

People measure several key issues of mining energy consumption: First, we have not considered the bitcoin ecology (such as bitcoin ATM) and the direct and indirect energy consumption costs of exchange, wallet and payment solution providers. Even with the standard energy cost of electronic banking transactions and bitcoin transactions, standard banking technology consumes more energy than bitcoin. It is shocking that the current power consumption rate of each Bitecoin transaction is as high as 491.4 kW/hour to 765.4 kW/hour.

In addition, although the number of digital transactions in the banking process is growing exponentially, the average power footprint of these transactions is as high as .4 kWh. (Perhaps bitcoin advocates will soon insist on refuting that these indicators do not include the cost of energy and materials needed to make legal tender in the body. )

Secondly, perhaps the most important problem pointed out by Alex De Vries, the use of cheap hydropower will also generate a lot of carbon emissions and costs. According to Tongjin statistics, nearly half of China and Sichuan have mineral capacity (48%). Due to the poor quality of the power grid, it limits the power export capacity. It is a large number of cheap hydropower, attracting a large number of bitcoin miners and trying to use low. Honest consumption and high pollution industry "

Finally, Alex de Vries pointed out that the electronic waste generated by the upgrading of mining machines is also a waste of resources and a new type of pollution source. In addition, at present, the most efficient bitcoin mining machine in the market is no longer a GPU mining machine, but an ASIC mining machine specially optimized for mining. Because of its "particularity", after the ASIC mining machine is shut down due to upgrading, it is almost impossible to reuse it.

according to the report, the annual e-waste produced by bitcoin mining is as high as 1,948 tons, which is equivalent to the total e-waste produced by countries in Luxembourg.

"Now, there is a clearer view and a more complete understanding of bitcoin miners and their mining energy consumption. What impact will it have on the environment when the mining machine is electronic waste? ? Renewable energy washing can't be more powerful and highly polluting. "Alex De Vries believes that such problems can be avoided by replacing the POW*** knowledge mechanism. For example, the POS*** knowledge mechanism can significantly reduce the energy consumption of Bitcoin and eliminate the need for dedicated, non-recyclable hardware. God said, "Even if you don't believe that pollution and carbon dioxide are a problem, it does have a huge waste of energy." V God believes that turning POS will reduce the energy consumed by Ethernet communication by more than 1 times. "The integration power required by the blockchain transaction itself is not great. Pow is its huge cost power, mainly to verify the digital signature consumed.
