Blockchain free worker platform
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.
1. Jinrong China Financial Instry Co., Ltd.
this is a digital currency trading platform in Hong Kong. At the beginning of trading, it developed on the principle of safeguarding the rights and interests of customers.

2. Bitfinex

It occupies an important position in the world's cryptocurrency trading and circulation. It also provides the world's most liquid registration policy and plays an important role in the world's trading operations, At present, it occupies the second place in the domestic regular blockchain platform
3. Fire coin network
this is an earlier digital currency trading platform in China, mainly trading bitcoin. As the third instry of domestic regular blockchain platform, it is the trading platform with the largest bitcoin trading volume in China. Many new digital asset trading platforms have been developed under the company, For the future development of the foundation
This is a digital currency trading platform jointly established by some digital currency enthusiasts, and its founder is Zhao CHANGPENG.

There are many kinds of digital currencies for trading, and their main functions are cash out and derivative trading. They are well-known in the world's exchangeshow many stages is the blockchain divided into&# 8194;
there are 1.0, 2.0 and 3.0 blockchains, and the digital currency dominated by bitcoin is blockchain 1.0; The smart contract platform centered on Ethernet is blockchain 2.0; The application scenario and platform of high-performance blockchain is blockchain 3.0. The simple conclusion is that 1.0 is mining and currency speculation; 2.0 is ICO and currency; 3.0 is the implementation of the project. The real landing projects are still far away from us. Most projects take stage 2.0 as the entry point of instry solutions. The combination of blockchain and instry enables blockchain to be applied in a certain instry&# 8194;
how to be a qualified blockchain project&# 8194; potential blockchain projects have different evaluation standards and different periods. The main reason for the outbreak of digital currency in 2017 is the promotion of ICO and Ethernet smart contract. In the past, projects that could meet these two conditions were considered good. Now, the measurement standard of projects is: & (1) There are application scenarios. The project itself has team, goal and real scene application. Because some teams or enterprises are not suitable for blockchain applications, it is a rather crude way to establish a connection between them&# 8194;&# 8194;&# 8194;&# 8194;&# 8194; (2) the multi parties involved in the blockchain can generate transactions (3) blockchain has a large number of communities and users. In conclusion, good blockchain projects can be applied refer to the case of Henan keoo Information Technology Co., Ltd

There are some differences between SOA and micro service architecture in terms of architecture division and technology platform selection
First, the architecture is divided into different levels2. Microservices are divided by Vertical Architecture and business capability. Each service completes a specific function, and service is proct
Second, the choice of technology platform is different2. Microservices can select different technology platforms according to different business characteristics, go to the center for unification, and give full play to the advantages of various technology platforms
Thirdly, the boundary processing mechanism between systems is different.
1. SOA architecture emphasizes the communication and decoupling between heterogeneous systems A coarse-grained and loosely coupled service architecture
2. Microservice architecture emphasizes the fine-grained splitting and deployment of the system according to the business boundary
The main goal of SOA architecture is to ensure that applications can operate interactively2. Microservice architecture, the main goal is to achieve new functions, and can quickly expand the development team

the suggestion is to redo the system, and then find the guardian God to reinforce the system security for you, so as to completely plug the loopholes.
