Application of blockchain big data in rail transit

1. 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.

2. The five elements are about Yin and Yang, eight trigrams, Qimen, tunjia, heaven, earth, people, gods and ghosts. In general, it refers to gold, wood, water, fire and earth.

3. If you don't understand this, don't do it. It's all virtual things. When the landlord asks questions, it's deceptive. It's obvious that those who advertise on this platform value your principal

4. Guess money network did not say what role..... It's just for gambling

cough, this property should be similar to body color
you will ask: after gambling? How to deal with a lot of guessing coins
I would say: maybe there will be some useful official notice in the future, such as activities ring the world cup
[reward method]

after the world cup, the top 9 users in the quiz list can get the reward from the post bar. At the same time, in addition to the top 9 netizens, we will randomly select 20 bar friends from the top 100 bar friends in the ranking to give out lucky prizes. Come and join us<

[award setting]

one first prize, three second prizes for Sony dsc-tx7c digital camera, five third prizes for iPod new shuffle 4G MP3, 20 lucky prizes for Internet travel storage bags, Logitech M215 wireless mouse, and the support for the event The final right of interpretation of this activity belongs to aitieba, and network employees are not allowed to participate in the activity to receive awards.

5. The answer is yes. The blockchain distributed accounting technology can completely record the source of big data and improve the storage, which solves the limitations of traditional big data in the scope of data collection. At the same time, jinwowo group uses the non tamperable characteristics of blockchain to provide the whole process tracking of procts and services for enterprises. It greatly ensures the authenticity of data sources, especially in the field of commodity circulation. Jinwowo blockchain technology will form a detailed list of platform transactions, completely trace the source of all procts and the transaction process, and build a protection wall for enterprises' honest operation.

[guide] while big data brings great opportunities to all walks of life, it also brings many challenges. Blockchain, with its characteristics of decentralization, distrust, high transparency and no tampering, can be considered that big data is endowed with higher security, transparency and privacy. So what are the effects of blockchain in big data

first, improving data quality

the essence of blockchain is a decentralized distributed ledger. It can also be understood as a non tampering, full history, distributed database storage technology. Therefore, blockchain technology can liberate more data. The trustworthiness, security and non tampering of blockchain technology fundamentally improve the quality of data and enhance the ability of data inspection

Second, dealing with the problem of data island

big data has a very serious problem of data island, and a lot of data cannot be obtained at present. Blockchain is expected to deal with this problem. This is mainly because blockchain is not only a distributed ledger, but also has the characteristics of decentralization and openness. As order maintainers in the financial market, regulatory organizations can also predict and analyze possible dangerous problems through the data chain in the blockchain

3. Dealing with data leakage

in essence, the blockchain is actually a decentralized database. Therefore, if the data of one node in the blockchain changes, other nodes will find it at the first time, so the possibility of data leakage will be greatly reced. Only in the form of private key can the identity information of each node in the blockchain be obtained successfully, and only the data owner can know the private key

IV. blockchain can protect the relevant rights and interests of data

for valuable data assets of indivials or organizations, blockchain can be used to register them, and transaction records are recognized, transparent and traceable throughout the network. The source, ownership, use right and circulation path of big data assets are clear, which is of great value to the transaction of data assets

v. traceability of blockchain

data can be stored in the blockchain from every step of collection, trading, circulation, and accounting analysis, so that the data quality can obtain unprecedented strong trust endorsement. At the same time, it also ensures the correctness of data analysis results and the effect of data mining

the above is Xiaobian's "what is the role of blockchain in big data?" I hope it can help you. In general, with the application of big data in many instries, engineers and developers with big data technology are very popular

7. Blockchain and big data are current cutting-edge technologies, and they can be combined with each other. Many big data platforms are based on blockchain. There are more than 30000 enterprises on the public service platform of SMIC's blockchain, which will connect all the enterprises together. In the future, it may radiate to the whole country.

8. The traceability of blockchain makes every step record of data collection, transaction, circulation and calculation analysis can be kept on the blockchain, which makes the quality of data obtain unprecedented strong trust endorsement, and also ensures the correctness of data analysis results and the effect of data mining.
