The leading country in blockchain
At present, there are quite a lot of MSB licenses in the United States. The bigger ones are Huo coin, coin an, and the smaller domestic second and third tier exchanges are all licensed. At present, the licenses are also a trend in the future. They are all moving towards standardization, and there are more than 20 applications for licenses every month
for example: US MSB, Estonia, Australia
e to the technical characteristics of blockchain, concentric mutual aid has three characteristics: first, all capital flows are open and transparent, which can not be forged or tampered with, and each user can exercise the right of supervision. Secondly, the transfer of all funds can only be carried out in accordance with the open smart contract, and there is no legal person for misappropriation and intervention. Finally, each user's personal sensitive information will be highly encrypted, and no one else can access it. Based on the above three points, the problems existing in the traditional network mutual aid mode have been solved one by one. In addition, in order to ensure the authenticity of the payment, the new "jury" system has been established in the supervision mechanism, which forms a professional identification system with lawyers, doctors, judges, police and other public officials, so as to ensure the authenticity and reliability of each payment, and completely eliminate the most critical defects of traditional network mutual assistance.
the definition of blockchain
in a narrow sense, blockchain is a kind of chained data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography
broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code
there are many channels to learn blockchain
① you can buy some books related to blockchain, learn some knowledge related to blockchain, take notes in your spare time, and consult relevant information
② watch some videos of blockchain on the Internet, the contents of which are easy to understand, with relevant examples, It's also a very good way to learn
③ you can take part in some offline blockchain learning exchange meetings, or take part in some training courses, and some teachers will answer questions for you
to sum up,
all roads lead to Rome. There are many channels to learn blockchain, and the best one is suitable for you
of course, blockchain has also been applied in real life, such as medical equipment corresponding to Ruitai coin, ant financial services, etc.
ut ultrasonic, a small instrument is simple and convenient, but the technical level of the operator is high, and it can detect internal defects
mT magnetic powder needs a magnetic powder machine, which is bulky and needs AC power supply, so it is inconvenient to construct
Pt penetration is more convenient than ultrasonic. It can only detect surface defects with cleaning agent, colorant and imaging agent
there are X-ray and gamma ray elements in RT. the former is less radioactive, and the latter will involve radioactive pollution with high risk coefficient. However, RT is also a method with accurate detection and the most direct evidence (X-ray film), so it is commonly used.
In fact, as of August last year, Bank of America had filed at least 30 patent applications for blockchain technology, while in February last year alone, they filed nine applications with the U.S. patent and Trademark Office
