How about companies that do blockchain of art

1. blockchain is an important concept of bitcoin. In essence, it is a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
characteristics of blockchain:

decentralized
e to the use of Distributed Accounting and storage, there is no centralized hardware or management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system
openness
the system is open, in addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all, and anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
autonomy
blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work
information cannot be tampered with
once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high<
anonymity
since the exchange between nodes follows a fixed algorithm, their data interaction does not need trust (the program rules in the blockchain will judge whether the activity is effective by themselves), so the counterparties do not need to let the counterparties generate their own trust by disclosing their identities, which is very helpful for credit accumulation<

the application of blockchain
the art instry
ascribe allows artists to use blockchain technology to declare ownership, issue numbered, limited edition works, and target any type of art in digital form. It even includes a trading market where artists can buy and sell through their websites without any intermediary services
legal instry
bitproof is the most advanced of many document time stamp applications emerging in recent years, which will make the traditional notarization method a thing of the past
development instry
colu is the first enterprise to allow other enterprises to issue digital assets. They can "token" all kinds of assets and make a profound impact on many people
real estate instry
the international bitcoin Real Estate Association (ibrea,) is not a company, and is more similar to an instry lobbying organization
Insurance Instry
Tongxin society is the first domestic application project of blockchain technology and an open mutual information service platform
thank you!

2. Art is very risky
blockchain is very risky
Art blockchain is very risky

3. It's cold and snowy in the Xiling mountains
if you have a collection worth millions,
if you can't sell it, it's bullshit
recently, Shaanxi calligraphy and painting art trading center, Shenzhen cultural property exchange, xiong'an World Art Bank building, Hainan International Culture and art trading center have been set up on the Internet, and even 5000 museums will be set up in Beijing. But Lao Wang wants to ask, do you want to pay? Previously, seven cultural relics appraisal units across the country charged 100 yuan for each piece of appraisal, Later, we set up a work of art authentication record, which costs 800 yuan. Now we set up a trading center. In a word, paying money is a liar. If we really want to do something practical for the sake of the people, now we call it work of art finance, work of art blockchain and work of art big data every day. The more we don't understand, the better we cheat
the most important issue of art trading is identification. Who are you looking for in these so-called trading centers and banks? According to the official propaganda, Qian weipeng and Qiu Xiaojun are employed by Shenzhen cultural property exchange. Is it true that these two are valued at 50 million yuan? You will definitely accept them and pay on the same day without any conditions, We minzang don't need to pay a cent. We can give you a 70% commission in the later period. Therefore, I suggest minzang take good care of its own money bag at this time
this is an ideal, but the reality is that we still need to collect money. Then collecting money will return to the old topic, art trade. Why do I want to go to these places? I sell them directly to the antique city, or I pay for poly and Jiade. Maybe the auction price is higher, or Cheng Shoukang, Li Jianchen and Zhang Dingyuan, so that they can contact the rich directly
if it is really for the sake of our people, we should amend the cultural relics law as soon as possible. What we need to see is the real things, not the empty things.

4. My relative was cheated for more than 200000 yuan in this way, but fortunately, he kept the receipt and so on. Later, he came back
