Antique entertainment financial blockchain company

2. There are still many domestic enterprises that are actually doing blockchain technology, such as fun chain technology, Vientiane blockchain, energy chain group, complex US technology, Xinghe blockchain, Zhigui technology and medical chain group. They are all well-known enterprises with good technology in the instry. Internet giants basically have blockchain sections.

3. It should be. After all, China is so big. Other domestic blockchain + financial applications need to be official and large-scale. Now Bank of Changsha has a cooperation with a public platform of SMIC blockchain, which seems to be a blockchain loan for small enterprises.

4. What is the domain of blockchain? Blockchain applications? The reason why we all say that blockchain is a subversive technology is that it is indeed the first time in the whole process of computer development that decentralized trust can be established from the technical level. Features: consensus, security and openness. First of all, blockchain is a multi-party consensus mechanism, and the consensus algorithm is the basis of building the whole technology trust. It does not rely on the trust of people and institutions, but a relatively democratic mechanism. Under the constraint of this mechanism, the authenticity, validity and persistence of data are guaranteed, so as to establish the trust foundation of this alliance business of multi-party Union and multi-party mutual supervision

secondly, blockchain is a relatively safe system. bitcoin is such a familiar blockchain application, and it is also the most successful blockchain application so far. So far, bitcoin has been running stably for 6-7 years. This system almost breaks everyone's idea of building a traditional financial system. First of all, it has no security facilities. Anyone who takes a machine into the network can join the network and work. In the whole bitcoin network, more than 80% of the machines are bare metal, They have neither good security protection nor any firewall measures; Secondly, because of the design of bitcoin, some of its data can track the history, prevent tampering and be irreversible

finally, it is an obvious feature of blockchain. It is a very open system. At present, there are many open source underlying implementations for your reference or use, and it is very scalable. It has been committed to establishing a multi center instry alliance or business alliance

Introction to Bubi blockchain

since its establishment, Bubi blockchain has been focusing on the R & D and innovation of blockchain technology and procts, has a number of core technologies, and has made substantial innovation in many aspects, forming a number of core technology achievements, such as: mathematically verifiable distributed consensus technology, fast large-scale ledger access technology, and so on Multi Chain general ledger technology supporting business form expansion, interconnection technology between heterogeneous blockchains, etc. On April 25, "gege integral" introced the integral system into the concept of blockchain, opened up by multiple parties, issued and exchanged integral, and promoted the circulation of integral. All cooperative institutions can jointly participate in transaction verification, account book storage and real-time settlement; The third-party payment platform of the enterprise points issuer makes the points in and out more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, credit and other fields. Bubi has been committed to building an open value circulation network with the core of decentralized (polycentric) trust, so that digital assets can flow freely

there are two extremes in the development trend of blockchain. Some people advocate private chain, while others advocate public chain. In fact, more than 90% of the mainstream applications in Europe and the United States are instry chain or alliance chain, that is, the upstream and downstream of an instry, or the semi open blockchain built by core enterprises, such as R3, LINQ of NASDAQ supported by chain, and some instry applications made by Dah to Australian stock exchange or Morgan

in fact, in the process of development and use of blockchain, it is around the following three important links: consensus, balance of book efficiency and scalability. Some geeks, such as bitcoin or Ethereum, are completely public. There are also some private chains used for efficiency transformation or connection between subsidiaries within enterprises. Most of them are upstream and downstream of instry alliances. They gather together for heating or jointly expand the business scale, which is the mainstream instry chain at present

blockchain naturally has two kinds of attributes: voucher and transaction. The attribute of voucher makes it the entrance of asset securitization and asset number, and the attribute of transaction enhances the free circulation of assets. Therefore, blockchain may become the infrastructure to build a free circulation network of value in the future

the field of blockchain? Blockchain applications? Referring to the development history of the Internet, the value free circulation network constructed by the blockchain is also an independent partial value circulation network (instry chain, alliance chain) formed by various instries according to their own needs in the early stage. In the later stage, driven by the demand for cross instry asset exchange, the instry chain is connected in series by some ways of interconnection, The formation of a de facto free circulation network of common value (public chain).

5. First of all, I'd like to introce some well-known blockchain companies in China, and then I'll personally evaluate which one is good. You can judge for yourself

1. Bubi blockchain company, which is engaged in the underlying technical services and instry solutions of blockchain. That is to say, an underlying blockchain is built, and an adaptation layer is built on it, so that enterprises can quickly establish commercial applications. The underlying blockchain is self-developed. The consensus mechanism is pbft, TPS is 5000 transactions per second, UnionPay is 2000 transactions per second, and bitcoin is 7 transactions per second. Of course, different underlying architectures lead to different performance, because Bubi's commercial blockchain pays more attention to performance. At present, Bubi is mainly used in digital assets, supply chain finance, supply chain traceability, public notary and other fields< 2. Bumeng blockchain. Theoretically, bumeng should be regarded as the proct line of Bubi, but Bubi is mainly engaged in the private chain, while bumeng is an alliance chain. So separately, bumeng is Bubi's layout in digital assets. The underlying technology is Bubi blockchain, but it encapsulates the blockchain according to the scene and provides API interface for enterprises. Enterprises issue their own assets on it. According to the characteristics of blockchain, they can freely circulate their assets. At present, some enterprises such as sunshine insurance, Qianxiang finance, crowdsourcing, Haohuo, etc. have joined in, and the assets in them include insurance policies, integral points, and so on Financial procts and so on. Finally, it is estimated that this platform will break through the barriers between assets, and the end users can freely use and transfer these assets. This is an interesting way for the blockchain instry, because it has both the opening of public chain and the security of private chain

Third, only chain, which is a commodity ID management cloud platform based on blockchain technology, provides enterprise users with commodity asset management, tracing, anti-counterfeiting verification, new supply chain management, etc. in the form of baas. Simple understanding is that only chain has done the content of "supply chain traceability" of Bubi blockchain

four, concentric mutual aid, concentric mutual aid is a mutual aid security platform, put some mutual insurance related information into the blockchain, and users can apply to become nodes, participate in bookkeeping, and maintain their own data

5. Xiaoyi is a decentralized network protocol based on blockchain technology, which digitizes the assets and interests of the real world, and carries out financial business such as registration and issuance, transfer transaction, clearing and delivery through point-to-point network

these five blockchain companies are probably well-known in China, and I personally recommend bumeng

first, bumeng uses the underlying technology of Bubi blockchain, which is very promising in the instry. It has the largest number of landing applications in China. Enterprises can not only use the blockchain technology at low cost (just call the interface, it seems that it is free), but also use the resources inside. Think about being on the same chain with many enterprises and docking resources in the future, User transformation should not be easy

Second, Weilian and Tongxin Huzhu focus on one field, and do not provide underlying technology and instry solutions. That is to say, if you are in this instry or can be used in the upstream and downstream of this instry, you can not be used in other fields. Take mutual security field as an example, zhongtuobang and zebra Club both choose bumeng. Of course, if it is an investment, you can consider it

Third, Xiaoyi, why not recommend Xiaoyi, because Xiaoyi is an open source project, and we all know the domestic business environment, especially when the instry is just beginning to develop, and the domestic market is different from that of foreign countries, Xiaoyi has gone through two rounds of ICO, which will be a great worry in the future operation, and at present, Xiaoyi has not been applied in practice, We have made a Fada platform, which has not been used by any company yet (guess it may be related to the factors of open source, who dares to open their data completely). Of course, the open attitude of Xiaoyi is worth encouraging. Although I guess the advantages and disadvantages of the code are well understood by peers, it is not clear

Fourth, why is there no recommendation for Bubby? Bubby has raised 30 million yuan a while ago, because Bubby is more open and has more resources. Of course, if the business requires high privacy, it can also choose Bubby blockchain

finally, for all my hard work, choose me!

6. Research on the maturity of supply chain finance of E-Chain Technology

7. The difference of wallets on the market is not obvious, mainly e to the classification:
centralized wallets: suitable for novices, easy to manage
decentralized
cold wallets (offline wallets)

8. If it's raw stone, the general quality (small particles and soft cracks) of Baijing is about 20 yuan per kilogram. If it's bracelet, I bought a better Baijing bracelet, 12mm, 20 yuan, which is less than 1 yuan per gram based on 25g. If it is more high-end varieties, such as garnet, amethyst, green ghost, the lowest quality of about 3 yuan a gram.

9. 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

10. 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.
