How to upload traceability data to blockchain

1.
The three characteristics of blockchain are well known, that is, decentralization, transparency and non tampering. The tamper proof feature makes blockchain used in many places. Such as proct traceability, privacy protection and so on
because the proction process it traces back to is artificially uploaded, so even if it is tamperable data, the authenticity of the data can not be guaranteed, and the substantive problem still can not be solved
generally speaking, although blockchain has brought great benefits, it is not perfect after all. However, blockchain technology has promoted the development of the times, and I believe its future is worth looking forward to
2. Blockchain technology brings new growth possibilities to these fields. For example, in the insurance field, combined with blockchain technology, we can see growth opportunities for reinsurance in the future; In the field of health care, the integration of medical data and file management can also be realized through distributed ledger technology; The combination of supply chain and blockchain technology will create more financing opportunities
all of the above are potential application fields of blockchain technology, but if the first large-scale application field of blockchain technology, I think it will be in the fields of insurance and health care
because the current data in these two fields are very scattered and chaotic, they can be integrated systematically through blockchain technology. In the future, a lot of business opportunities can be found after specific analysis of these data
some excellent digital currencies have begun to appear in China, such as Puyin, a tea standard digital currency launched by Puyin group. Puyin is a high-quality Tibetan tea asset that is stored, identified, evaluated and authorized by three parties, and a standard digital currency that is issued through encryption and digitization.

3. How to store information on the blockchain: call the API provided by the blockchain platform
generally, the blockchain platform will provide corresponding interfaces, such as RPC, json-rpc, HTTP, etc. of course, the platforms are not the same, and the degree of friendliness is different
some companies specializing in API, such as blockcypher, can provide friendly calling interfaces, and it is not very convenient to write answers on the mobile phone, Search below
as for the storage content, add a point: in addition to the conventional cloud storage, file entities on the file hash record chain also have blockchain based storage schemes, such as IPFs, storej and so on

4. With the help of blockchain technology and alliance chain node, wangchain technology integrates and writes the information of commodity raw material circulation process, proction process, commodity circulation process and marketing process into the blockchain, and uses the tamper proof attribute of the blockchain to realize the whole process traceability of one thing one code
5. VAT invoice is also a kind of invoice. Enterprises with the qualification of general VAT taxpayer can apply to the competent state tax department for purchasing VAT invoice and issue it through the anti-counterfeiting tax control system. Enterprises with the qualification of general VAT taxpayer can dect vat by VAT invoice. Special invoice is the abbreviation of "VAT special invoice". An invoice issued for the sale of goods subject to VAT. After the implementation of the Provisional Regulations of the people's Republic of China on value added tax, in order to ensure the implementation of the tax dection system of value-added tax which belongs to extra price tax, it is printed and distributed for the use of enterprises. When taxpayers sell goods or taxable services, they shall issue special VAT invoices to the purchasers, indicating the sales amount and output tax amount respectively. The use of special invoice as dection voucher is limited to the general taxpayers who are both VAT buyers and sellers.
6. Dmtc mainly uses blockchain technology to integrate the resources of agricultural supply chain, combined with the support of soft and hard chain technology, so as to realize the whole process of agricultural organic food proction record, check, tamper proof and traceability, and thoroughly solve the practical problems of agricultural development. It includes data acquisition, data security and data sharing
in terms of data collection, through artificial intelligence and Internet of things technology, dmtc runs through the whole agricultural ecological chain. During agricultural proction, it automatically records the proction environment data, proction process data, transportation, sales and consumer behavior data of agricultural procts
in terms of data security, the existing traceability IT architecture is used to maintain the security of the system through network equipment and Agricultural Internet of things (IOA)
in terms of data sharing, the data collected in the whole process of dmtc can be conditionally shared with users in the whole supply chain of ecological agriculture, and the proction and transportation data can be shared with consumers, so as to trace the origin and development of procts, guide agricultural procers to adjust proction direction and improve proction efficiency.

7. I saw an agricultural traceability project of dmtc rice before -
is to install an RFID chip on the proct, which records the whole life cycle of the proct, which is equivalent to that every commodity has an identity tag. These data will be linked in real time and form a tamperable information to ensure the safety and traceability of goods
my understanding is probably like this, so should other traceability procts
you can also ask me if you have any questions, I hope it will help you!

8. As far as I know, vonetracer is a blockchain traceability platform based on
blockchain
technology independently developed by wangchain technology, which is different from the traditional one. Instead, vonetracer uses
blockchain technology
to realize the real traceability of food and increase trust for traceability. After the verified proct information is linked, the data on the chain is backed up in each
network node
, As a result, the cost of data modification in the whole network is very high, which ensures that the data in the blockchain network is difficult to be tampered with, and the data can be checked and trusted, so as to truly realize the source quality control of agricultural procts.

9. The administration building of Shenzhen Airlines base is on terminal 4 road, about 1km away from the terminal. It takes 20 minutes to walk from Bao'an airport
there is no bus. If you are in a hurry, you have to take a taxi. Check in floor map
< p class = "f-aid" style = "margin: Auto;" > This data comes from the network map, and the final result is subject to the latest data of the network map

10. The return on investment is very good. It is a kind of currency that can be used in the digital world. In October 2017, it was officially launched on the international trading platform, with a total amount of 27 million. It is a powerful currency.
