Antiques and blockchain

1. bitcoin, which has been popular for a long time, must be well known to everyone. Bitcoin is a revolutionary innovation based on blockchain. After bitcoin, all kinds of digital currencies have sprung up. Then, CRBC, which is also based on blockchain project, is different from other digital currencies? What is its biggest characteristic? What is the technical principle of it? The author will be here to solve the puzzles one by one
the definition of CRBC is actually very simple and easy to understand. Its full name is the international cultural heritage chain. It is actually a digital asset chain that uses art treasures as collateral and credit guarantee. It is a digital asset developed based on the blockchain erc2.0 as the underlying technology, and uses smart contracts to build consensus mechanism, Create a traceable and decentralized ancient culture art exchange or bank
the biggest difference between CRBC and other digital currencies is that CRBC itself is combined with antiques. Under the traditional financial system, small and micro enterprises are faced with the problems of no asset mortgage, difficult financing and expensive financing. However, the traditional antique market is faced with the instry problems of difficult circulation and cash flow, and many investment and collection of art The understanding of antique calligraphy and painting is facing great trouble. This provides an unprecedented opportunity for the combination of antiques and finance. The integration of ancient cultural artworks and financial innovation aims to accelerate the circulation of artworks and promote financing and investment. This is an instrial chain that needs multi-faceted integration, as well as a set of scientific and standardized operation mode and process. If you want to integrate art or antiques into the financial channel, you need to go through the evaluation and appraisal of the authoritative expert team first, and formulate detailed proceres on the process of transferring collection and loan, so that each transferred collection has a relatively fixed and visible value space
CRBC has three characteristics: unifying the value estimation standard, integrating the cultural relics trading market, and financing the active market. There are many chaotic phenomena in the appraisal instry, such as nonstandard, arbitrary charges and non refundable appraisal fees. The same collection, different experts and institutions give different appraisal results and value estimates. Even the same collection and the same expert give different appraisal results at different times. CRBC integrates and separates physical objects, property rights, identification, evaluation and contract randomly through blockchain technology, which can unify the credibility and is difficult to fake. The ancient culture and art trading platform built by CRBC can integrate the above-mentioned scattered, centralized and pledged cultural relics trading markets, and meet the needs of single, scattered, bulk and batch trading modes. CRBC has changed the traditional credit guarantee mechanism, allowing new small and medium-sized enterprises with good reputation, domestic and foreign capital, cultural exchange and Art Bank to enter CRBC as nodes, which can speed up the integration of financial elements into the antiquities trading market, transform the art value into economic value reasonably, and proce good market effect
the core of the construction and implementation of CRBC is divided into three parts: smart contract, distributed storage and data analysis system, and data traceability system. CRBC does not provide a centralized data storage center for all the cultural relic identification data recorded in the main chain, the financial operation and capital operation data of enterprise nodes, and the capital management data of users and investment fund nodes. Instead, it uses CRBC as a value incentive to build a distributed storage and data processing system to ensure the security of system operation, Openness and transparency. The data traceability system is the credit lifeline of the whole ecosystem of CRBC. It involves the value identification of art collections as value guarantee, the financial operation data of enterprises and the operation flow content of the financing funds. By establishing its own aggregation SDK database, the art information is partitioned, and each new identification result will be recorded on the blockchain at the first time, It will be witnessed by all CRBC holders. CRBC ancient culture and art exchange will synchronize every piece of information from identification to auction and collection channels within 24 hours, making every piece of information of art transparent, searchable and more rapid.

2. This kind of thing can only admit bad luck, even if the police, the hope of money back is slim. Therefore, if you want to trade bitcoin in China, you must choose one of the most powerful exchanges, such as okex, which has a large trading volume, and its technical strength and security are also recognized as the best in the circle.

3. This friend's answer has been very pertinent. It is the direction that the standard blockchain technology features can be combined with the physical instry at this stage
there is no point in talking on paper, I don't know whether the subject is engaged in antiques collection or blockchain technology
if it is antiques, we should know that now China antiques network has started to combine blockchain technology with antiques
this website has launched a blockchain based digital currency, Gubi, which is mainly used for the trading of antiques collection
and the characteristics of digital currency itself In the future, blockchain technology will be used to distinguish counterfeits
that is, the characteristics of traceability, non tampering and decentralization mentioned by this friend
this is the most important link in the combination of blockchain and entities

4. The reason why there is today's chaos in the antique instry is known as the fraud instry. In addition to the misunderstanding of the outside world, it is inseparable from the confrontation and infighting of the antique instry itself. Let me give you a brief introction. Let's see which group you support
the two major forces in the antique world:
the elderly group: according to the legal age is 60, if calculated according to the latest retirement age is 65, the elderly has retired for six years. The elderly group in the antique world refers to the group over 50 years old, mainly focusing on eye science, and some people oppose machine detection of the age of antiques, Some of them, of course, are also actively studying the age of machine detection of antiques. They are the main body of the Curio TV treasure appraisal program. They have no university culture and are generally half-way monks. Because they like to switch to the instry of antiques, they have deep social experience and are older. For example, ye Peilan, Li Zhiyan, Geng Baochang, Deng Dingsan, Cui Kai and Cai Guosheng think that the new generation of people are ignorant and do not know how to respect and respect the elderly, The supporting forces are official museums and television stations
new generation group: after a good full-time university ecation, this group is young and energetic. They are extremely disgusted with the elderly group. They think that the elderly group will only go around and make false identification and false evaluation. They don't do practical things and are full of lies. If they want to have real skills, why don't they go to Taobao and charge hundreds of yuan for identification fees everywhere, Among them, Li Jianchen, the most important representative of the new generation group, thinks that the antiques identification adopts the international back-to-back identification and evaluation system, as well as the method of blind identification of antiques using the same model of machine at different times and places, and the forces behind it are responsible national capitalists
seven gangs in the antique world
the first one: giant auction company
Christie's, Sotheby's, poly, Jiade, Hanhai, Kuangshi, oyunxuan and Xiling Seal society formed an alliance of attack and defense
the second largest Gang: Antique experts
this group is very complex. Some farmers with good image recite a few lines and become antique experts. Some museums retire and become antique experts. Some antique shop owners become antique experts. For example, Cui Kai, Wang lianqin, Deng Dingsan, Yang Shi and Yang Baojie all belong to this category
the third largest Gang: minzang
this group has made a great contribution to the protection of ancestral cultural relics from damage
the fourth largest Gang: counterfeiting
this group has formed a complete instrial chain. There are seven counterfeiting bases in China, supported by local policies. Generally known as Changchun, Shenyang, Shijiazhuang, Zhengzhou, Luoyang, Wuxi and Jingdezhen, they are all famous antique counterfeiting bases
the fifth largest Gang: fake auction company
this group mainly charges customs fees, appraisal fees, storage fees, auction fees, catalogue fees and other various fees, and at the same time, they cheat by counterfeiting poly, Jiade, Christie's and Sotheby's. In 2016, more than 700 companies and more than 1300 people were arrested in Shanghai, more than 900 companies and more than 5000 people were arrested in Guangdong in 2018 and 2019, more than 100 companies and more than 500 people were arrested in Xi'an. In 2020 and 2021, this group is mainly located in Cheng, Zhuhai, Shenzhen, Kunming and other places, so we should be careful
the sixth largest Gang: exhibitions, expositions, bed exchanges, stalls, trade fairs, e-commerce, galleries
this kind of group is very complex, some of them buy and sell in order to earn a price difference, some of them are collectors who don't collect and go to set up stalls to sell
big data, finance, blockchain and filing of the seventh largest Gang
these words are very fresh, feel tall and have a sense of science and technology, but please remember, they have nothing to do with folk collection
the chaos in the antique world has not been formed in a few years, but in the past 20 years. Why is it so? Ma Wei has a good saying: "Yang Boda, the vice president of the Palace Museum, sold his dignity and the most basic conscience of the antiques expert for the appearance fee of 5 million yuan. Liu Yan, an antiques collector, no longer believes that the words of the antiques expert are for the truth. A voice of CAI Guosheng connects the Shandong Qilu treasure expert with the Xiaoshan Airport, which is confusing, Let the collector no longer believe the expert's words. "
I don't know what else to believe in the antique world. The confrontation and infighting between the two forces and seven gangs will only consume themselves, and foreigners will be very happy.

5. The first kind of national teams, represented by certification, finance, blockchain and big data, usually don't do treasure authentication activities. They all make money by running antique training courses, art finance, art blockchain and art big data, and the lowest is tens of millions of yuan. But ordinary shareholders can't do it
but the national team is not always so cold. Recently, the national team is also revising the cultural relics law. Maybe the spring of the antique world will come
the second kind of investors, who have suddenly taken shares in the primary and half market
you can see how the rich have operated in the past seven or eight years. For example, Ma Yun registered new companies in the art market crazily. A few days ago, Ma Yun registered Dajingtou (Shanghai) No.2 culture and Art Co., Ltd., which has been in deep storage for many years, This time, it was also revealed that the five members of the behind the scenes team who never made public were Cheng Shoukang, Qiu Guoshi, Li Jianchen, Zhai Jianmin and Jiang Bingqiang. Looking back on Ma Yun's experience in the art market in recent years, he photographed Zeng Fan's "Peach Blossom Garden" oil painting for HK $36 million in 2014, wrote calligraphy, painting and seal engraving himself, and worked with major painters to create many works
the third category, people who invest in the value of antiques
this kind of investors in the antiques instry are relatively lonely, most of the time they don't move, and their collections are high, fine, rare and unique. As a result, the antiques market will pick up. Of course, they should participate in it timely. In fact, in the antique market, there are not many opportunities to make a lot of money. It is impossible for everyone to make a lot of money.

6. Is your formula CA FCA, and how to use this formula to push, add, subtract, what do you don't understand? FCA is the compressive load that the concrete can bear plus the compressive load that the longitudinal reinforcement can bear, and f ′ ya ′ s is the total compressive load that the member can bear. It can be multiplied by a factor of 0.9 for more safety; φ It's related to slenderness ratio. The bigger the slenderness ratio is, the better the slenderness ratio is, φ The smaller is the bearing capacity of the longer member.
