One account chain mining
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
There is no law in China to ban bitcoin, so it is not illegal to mine and earn bitcoin
it is not illegal to buy bitcoin in China. In 2013, five ministries and commissions jointly issued the bitcoin risk notice, which states that although bitcoin does not belong to legal tender and is not legally compulsory, people can freely participate in bitcoin trading activities when they voluntarily undertake risks
"notice" clearly defines the nature of bitcoin, and holds that bitcoin is not issued by the monetary authority, has no monetary attributes such as legal compensation and mandatory, and is not a real currency. In terms of nature, bitcoin is a specific virtual commodity, which does not have the same legal status as currency and cannot and should not be used as currency in the market
however, as a kind of commodity trading on the Internet, ordinary people have the freedom to participate in bitcoin trading at their own risk
the notice requires that at this stage, financial institutions and Payment institutions shall not price procts or services with bitcoin, buy or sell bitcoin as a central counterparties, underwrite insurance business related to bitcoin or include bitcoin in the scope of insurance liability, and provide other bitcoin related services to customers directly or indirectly, Including: providing bitcoin registration, trading, clearing, settlement and other services for customers; Accept bitcoin or use bitcoin as a payment and settlement tool; Carry out bitcoin and RMB and foreign currency exchange services; Carry out bitcoin storage, custody, mortgage and other services; Issuing financial procts related to bitcoin; Take bitcoin as the investment target of trust, fund, etc
in order to avoid over hype of virtual commodities such as bitcoin in the name of "virtual currency" and damage the public interest and the legal tender status of RMB, the circular requires financial institutions and Payment institutions to correctly use the concept of currency in their daily work, pay attention to strengthening the ecation of the public's knowledge of currency, and correctly understand the concept of currency The concept of correctly treating virtual commodity and virtual currency, rational investment, reasonable control of investment risk, and maintenance of their own property security should be included in the content of financial knowledge popularization activities, so as to guide the public to establish a correct concept of currency and investment

I can use it
it may be a mine card
is not worth it
brand new, three-year warranty sotay 1065 only needs 1399, but the performance is only 10% less. The vast majority of games are a few frames away, so what you should be able to play is still able to play. I don't know how long it took to buy one. I don't know if there are any second-hand miners. Why bother to come here

Ping An technology, founded in 2008, is a wholly-owned subsidiary of Ping An group. The company is headquartered in Shenzhen and has branches in Beijing, Shanghai, Cheng and Nanjing
artificial intelligence is one of the core technologies of Ping'an science and technology, and has formed a series of solutions including predictive AI, cognitive AI and decision-making AI. Predictive AI based on disease prediction model has been applied to the prediction of influenza, diabetes and other diseases; Especially in the field of cognitive AI, face recognition, voiceprint recognition, OCR, image recognition and so on
extended materials:
Ping An technology is also building AI intelligent cognitive middle platform to realize business connection. Different from other middle platforms, it is not only a capability middle platform, but also a strategic middle platform. As a capability platform, Ping'an intelligent cognitive middle platform integrates AI technology capabilities as an integrator downward, and empowers services as a solution provider upward. The integration of upper and lower resources reflects the value of middle platform
at the 10th annual meeting of China Information directors in 2017, Ping An technology's smart customs program also won the "2017 China informatization outstanding Program Award", and Ping An technology's assistant to the general manager & amp; Chief proct officer District Haiying won the "2017 China informatization leader award"
Ping An technology and Century Internet Data Center signed a strategic cooperation to build a smart city base, invest in the establishment of a data center, and expand smart city projects. After the research of smart city scheme, promote the instry standard and common scheme, and promote and export the smart city together. In addition, Ping An technology has reached strategic cooperation with century Internet blockchain Laboratory of Central University of Finance and economics and Beijing Aerospace smart core technology Co., Ltd. to jointly promote instrial research and application of blockchain
in terms of application scenarios, one account chain platform has been put into use in many scenarios, such as blacklist sharing, supply chain finance, one account communication of financial institutions, small and micro enterprise loan platform and asset platform
for example, in the process of traditional bill transfer, there are some pain points, such as cumbersome bill verification process, difficult to predict the upstream and downstream risks of bills, time-consuming and labor-consuming transfer proceres, etc. There is a bill asset trading system on the one account inter-bank platform of financial institutions using ping an one account chain technology. The bill holder only needs to enter the bill information on the platform. After the bank's approval, the platform will digitize the bill and save it in the blockchain. At this time, the bill becomes an unchangeable digital asset. In the process of bill transfer, the platform will automatically generate the transfer contract. No matter where the operator is, under the authorization of the company, he can sign the contract digitally through the platform to ensure that the signed contract can not be tampered with. The change information of bill ownership will be permanently stored in the blockchain together with the whole process information of bill transfer, Double protection of the authenticity and effectiveness of bill transfer, and greatly improve business efficiency. The worries of bill verification, official seal verification and communication cost will be solved
of course, this is just the tip of the iceberg. You can find other apps on the official website.
Ping An's technology company financial one account link officially launched a blockchain solution, one account chain. According to the introction, the solution has three advantages: sparrow privacy middleware guarantees data privacy security on the fimax underlying framework, core high-performance underlying improves throughput, and Concord one click deployment and management platform optimizes user experience
to put it simply, some of the bottlenecks restricting the implementation of blockchain in the financial instry have been basically solved. With the continuous optimization and updating in the later stage, blockchain will have a subversive impact on the financial instry.
