Tencent cloud blockchain service

1. 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..

Ma Huateng: blockchain, line; ICO, no way

at the two sessions, Ma Huateng said that the topic of blockchain has been very hot recently, and even some people teased that the Internet before blockchain was "classical Internet". Although blockchain technology is innovative, how to make good use of this technology is another problem

in Ma Huateng's view, blockchain technology can be applied in many fields, especially in the aspect of the uniqueness of digital authentication objects. Just like a file or bill in reality, blockchain technology can be used to ensure that they cannot be copied or tampered with. Compared with traditional IT technology in the past, blockchain has epoch-making significance in truly simulating the uniqueness of documents and receipts in real society

Ma Huateng thinks that there are still many risks in doing digital currency ICO. "If everyone can issue digital currency freely with blockchain technology, it will cause a lot of regulatory problems," he said

for example, the golden red envelope project in the 2017 Spring Festival internal test is Tencent's attempt to record users' digital assets with blockchain technology. In addition, Tencent also uses blockchain technology to rece the problem of information asymmetry

in addition to finance and public welfare, Tencent also reached a cooperation with Intel in September 2017, announcing that both sides will jointly develop blockchain technology to improve the security protection capability in the Internet of things scenario

3. By 2015, a new technology, blockchain, is likely to be the next connector
as the underlying technology of bitcoin, block chain has broken through the financial instry, especially with the emergence of the alliance chain technology, the block chain can become the core technology of "Internet plus". At the May 2015 Guiyang big data Expo, Ma Huateng emphasized that "Internet plus" is also a kind of connection ability. Then, Tencent naturally will not miss the block chain, that is, the "Internet plus" era connector.
the micro public bank led by Tencent has started to practice in the exploration of blockchain
in May 2016, Weizhong bank participated in and launched the financial blockchain cooperation alliance (hereinafter referred to as "jinlianmeng") in Shenzhen, China. In June, it launched the alliance chain cloud service based on Tencent cloud. At the end of September, it reached a cooperation agreement with Wanxiang Group ring Shanghai blockchain international week
this series of signals shows that Tencent has entered the competition of blockchain and is trying to make blockchain the next connector (from Netease News)
Ethereum has built an intelligent contract platform by using blockchain technology; European crowdfunding uses blockchain technology to serve the real economy, making crowdfunding more open and transparent.

4. There are few real baas that have been approved by the state. At present, the mainstream platforms are Tencent's tbaas, Jingdong Zhizhen chain jdchain, ant blockchain baas, Rongze's rbaas, network's Intelligent Cloud and Huawei's cloud BCS. Among them, the top four baas platforms are teams that have been researching and developing blockchain technology for several years, R & D capabilities are very strong.

5. Yes, blockchain is a new distributed infrastructure and computing method that uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data, Self development costs are high, you can find related service providers, such as: Renren chain

6. To be exact, blockchain and traditional server cannot be compared together, because blockchain is a technical model, while server is a kind of hardware resource
but if we have to compare them, we can first see the differences or connections between the two characteristics
the traditional server is centralized
take a look at the figure below, it is a typical centralized network, the most central is the server, the others are clients, the server is responsible for providing services to all clients, and the client obtains services from the server, such as downloading files.

7. Take the bus, take the light textile city bus station, the ticket price is 20 yuan ~ 10 times a day

8. This paper introces the architecture of cloud computing from the technical point of view:
four modes of cloud computing: public cloud, private cloud, hybrid cloud and Instry Cloud
cloud computing architecture: infrastructure layer, cloud platform layer, business application layer and business management layer
computing service mode: IAAs, PAAS and SaaS
Key Technologies of cloud computing: virtualization, distributed data storage Cloud computing management platform and other technologies

9. It specifically refers to enabling users to quickly build their own IT infrastructure and blockchain services on an elastic and open cloud platform. In addition, the use of baas can greatly rece the cost of realizing the underlying technology of the blockchain, simplify the construction and operation and maintenance of the blockchain, meet the personalized needs of users in the face of various instry scenarios, and quickly deliver customized baas in one stop. Hope to adopt, thank you
