Blockchain data service

1.

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin,

in essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information of bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

most blockchain public chains are limited by scalability. The biggest feature of blockchain technology is decentralization, which requires that all accounts in the network need to deal with the accounting process. Distributed accounting has high security, low misoperation rate, political neutrality and correctness

however, blockchain technology embraces these features at the same time, sacrificing scalability, unable to meet the personalized supervision, and slightly insufficient in protecting data privacy. Moreover, with the increase of the number of ledger, the interaction delay will increase exponentially, that is to say, the more ledger in the blockchain network, the higher the delay

2. In many cases of blockchain application, we can always see the word baas. Baas is the abbreviation of blockchain as a service, which is translated into "blockchain as a service" in Chinese. So what is blockchain as a service baas? With this question, we will follow Xiao Wang of Renren blockchain technology team to discuss it carefully
according to Xiao Wang, the concept of blockchain as a service (baas) is mainly proposed by Microsoft and IBM. To put it bluntly, it is actually a new type of cloud service, a cloud service combined with blockchain technology. For example, Microsoft's azure cloud computing platform and IBM's bluemix garage cloud platform all provide blockchain as a service baas
blockchain as a service (baas) is a space created by enterprises such as Microsoft and IBM from their own cloud service network to run a blockchain node. Compared with ordinary nodes and exchange nodes, the main purpose of baas nodes is to quickly establish the development environment they need, and provide a series of operation services based on blockchain, such as search query, transaction submission, data analysis, etc. these services can be centralized or decentralized to help developers verify their concepts and models faster. The service of baas node is reflected in: stronger tool, easy to create, deploy, run and monitor blockchain..

3. 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.

4. Hello, stock trading software can buy money funds. You can apply for it in the form of subscription, or you can directly purchase exchange traded monetary funds like stocks.

5. It may be running away or being sealed up. Anyway, illegal trading platforms have such risks.

6. In order to ensure that big data can be truly implemented and used by the state, enterprises and the people, a special big data underlying technology blockchain emerges as the times require. After years of controversy, in 2017, blockchain entered the "first year" from pure theory to application
compared with pure big data technology, blockchain technology breaks the traditional big data monopoly, avoids the illegal factors of big data application, extends data application to all walks of life, and makes data flow, complete storage and system analysis at ease.

7. Today, big data, blockchain and other new technologies are sweeping the world, "digital economy" is profoundly changing people's lives and lifestyles. As a new driving force of economic growth, the role of "blockchain + big data" is becoming increasingly prominent. It is one of the technology hotspots in the forefront of Internet Science and technology. Relying on such a perfect combination, including e-commerce, Internet of things, Internet of things, Internet of things, Internet of things, Internet of things, Internet of things, Internet of things, etc The development of Internet, including government affairs, will open up a new situation, and many cross instry and cross regional innovative cooperation modes will be established

and Chongqing jinwowo network technology group has built an Internet innovation ecosystem with "blockchain + big data" in an all-round way. It aims to strengthen the ability of big data collection and analysis through the R & D and application of blockchain technology, and provide reasonable and legal technical development and application guidance for different enterprises and indivial users. Let the indivial user become the "digital business" who obtains the Internet dividend with the effective behavior record, let the enterprise user rece the operation cost and improve the accuracy of market delivery.
