Data resource construction based on blockchain
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: it is more instrumental and easy to create, deploy, run and monitor blockchain.

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.
Blockchain has the advantages of decentralization, distributed accounting, encryption and traceability, which can ensure the integrity and authenticity of the data on the chain. Once it is tampered or forged, it can be found. At the same time, because the blockchain has the characteristics of Distributed Accounting, even if the data on indivial nodes are deleted, other nodes can still save the data completely, ensuring the normal operation of the whole blockchain storage system
Shanghai published the opinions on comprehensively promoting the digital transformation of Shanghai city. Focus on the wide application of new technologies, and vigorously enhance the level of urban innovation. Accelerate the construction of digital infrastructure, promote the coverage of Gigabit broadband, 5g, Satellite Internet and other high-speed networks, build a high-performance public computing center, build digital platforms such as artificial intelligence, blockchain and instrial Internet, and firmly support digital applications in various fields such as economic development, public life and urban governance. Support the next generation of information and communication, high-end chips, core software, v2x vehicle road collaboration and other new technologies in the urban digital transformation, and take the lead in large-scale implementation, so as to further consolidate the advantages of digital technology. Focus on brain like intelligence, quantum communication and other key areas of cutting-edge technology, deeply integrate with urban digital transformation, strengthen key core technology research and functional platform construction, and vigorously enhance urban digital innovation ability
since the national development and Reform Commission incorporated the blockchain into the new infrastructure, the whole country has ushered in the upsurge of blockchain policy. The central and local governments have promulgated blockchain related policies one after another, taking the blockchain as the main breakthrough in the field of new economy and technology, building the future strategic competitive advantage, and the related application scenarios of blockchain are hot. The deep integration of blockchain and instry is the embodiment of maximizing the use of blockchain< based on "blockchain + justice + application", the easy security platform has successfully built a paperless one-stop service platform for business cooperation, providing E-contract, right protection and Internet notarization services for enterprises and authorities, and helping them solve the problems of high operating costs, chaotic management of contracts and seals, unsafe data storage and difficult accountability for network infringement. Completely transform the traditional business model, create a comprehensive upgrade of digital office
first of all, by using all data chains in the blockchain for prediction and analysis, the regulatory authorities can timely discover and prevent possible systemic risks. The decentralized characteristics of the blockchain can eliminate the information island in big data risk control, and improve risk control through information sharing
secondly, the distributed database of blockchain can improve the poor quality of big data risk control data, and solve the problems of data format diversification, data form fragmentation, lack of effective data and incomplete data content
finally, blockchain can prevent data leakage. Because the blockchain database is a decentralized database, any node's operation on data will be found by other nodes, thus strengthening the monitoring of data leakage.
