After the United States finds bitcoin
You should be talking about the loss of bitcoin account password of bitcoin trading platform or online wallet. There are generally three solutions:
1. Retrieve or reset the password through the bound mobile phone number or email
2. Help people find or reset their passwords through customer service staff
3. Retrieve or reset the password by submitting the real name authentication information
Personally, I don't think blockchain development technology is reliable. It's just what kind of R & D technology group you choose. Even if you choose a better R & D technology group, you may not be able to achieve the blockchain technology you require. Different instries and fields have different technical indicators, not to mention this complex new technology. On the other hand, let the R & D technology group agree with the machine instry thinking you need to apply, otherwise the procts developed will not meet your requirements. We focus on the professional field of blockchain technology, and the project has been carried out for more than a year, but it has not been successfully implemented. The difficulty is that overthrowing the traditional model will touch a great chain of interests, so it must be a process of graal infiltration
according to what you said: blockchain based on machine learning can be understood as asking a technical question
I hope the above answers can help you
1、 Open pit mining: in general, diamond mines are mined around kimberlite pipes. The middle of the pipes is the place where high-quality diamonds are most concentrated, which is usually characterized by huge holes. When the Kimberley rock pipeline was found, miners g out vertically from the ground surface
Second, underground mining: this mining method is safer and more efficient, especially with the deepening of the mining process, it is difficult to judge whether to continue mining to expand the mine. Underground mining only needs to open a tunnel to extract diamonds under the surface, which is more reasonable and less dangerous. Sometimes a combination of underground and open-pit mining is used to make a tunnel from the pit into the surrounding rock Extraction of kimberlite from the mine: kimberlite can be released from the earth's crust by artificial explosion, and a large number of rocks can be destroyed by explosion, but it can not be detected on site. It is wrapped with diamonds and must be transferred to another place for processing and diamond extraction by large trucks and steam shovels, Generally speaking, there are 0.5 carats of diamonds in one ton of mud (4) percussive Mining: rivers and streams will bring kimberlite to the river bed, shore, or even coastal zone to form percussive sand deposits. Percussive mining is also known as artificial mining, because the miner has to go to the percussive sand deposit to search for diamonds artificially. The farther away from the kimberlite pipeline, the lower the output of diamonds and the more sparse the distribution density of diamonds. Therefore, percussive mining is not suitable for instrial diamond mining

1. The Kimberley diamond deposit was discovered by the Burnett brothers in 1870. It is this discovery that makes people know which kind of rock may contain diamond. It's a volcanic rock formed after the magma of ancient times cooled. In places where garnet and olivine are proced, the possibility of finding diamond is relatively high. Therefore, garnet and olivine become the "indicator minerals" for diamond
From 1866 to 1914, 50000 miners used shovels and other tools to excavate, and a total of 2722 kg of diamonds were excavated. The South African government is trying to apply for the Kimberley pit as a world heritage site Third, open-pit mining is a process of removing the covering from the ore body to obtain the required minerals and extracting useful minerals from the open surface stope. Open pit mining operation mainly includes perforation, blasting, mining and loading, transportation and mping. Compared with underground mining, open pit mining has the advantages of full utilization of resources, low dilution rate, suitable for large-scale mechanical construction, fast mine construction, large output, high labor proctivity, low cost, good working conditions and safe proctionIn 2021, the price of bitcoin has gone up wildly. It can be said that the price is very high now< at present, it has increased by more than 200%. Such a rise also surprised many people. Similarly, we can see that its current price has been highlighted, which makes many netizens' cognition, and it is very terrible
at the same time, although the wallet provides the user with an opportunity to try a password for 10 times, we can see that the reason why he wants to withdraw the money is that we can understand it. In other words, as far as a bitcoin is concerned, its current situation is that it cannot be retrieved at will. If it is retrieved, its wallet will have a great impact on bitcoin. At present, the official has also made a corresponding statement, saying that if you want to seek their official status, you must pay 3000 US dollars for a compensation to find out the corresponding password, which gives people a bad feeling. At the same time, many netizens said that the password of bitcoin can not be re encrypted, because bitcoin is very special, so bitcoin never belongs to a currency, it only recognizes a secret key but not the owner's
