Created on the 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.
From the perspective of technology and architecture, I will tell you my understanding of blockchain in common language
what is blockchain? In a word, blockchain is a storage system. To be more specific, blockchain is a distributed storage system without an administrator and each node has all the data
What are the common storage systems like
first, how to ensure high availability
the common storage system usually uses "rendancy" to solve the problem of high availability. As shown in the figure above, if the data can be copied into several copies and rendant to multiple places, high availability can be guaranteed. The data in one place is hung, and there is data in other places. For example, the master-slave cluster of MySQL is the same principle, and the raid of disk is also the same principle
two points need to be emphasized in this place are: data rendancy often leads to consistency problems
1. For example, in the master-slave cluster of MySQL, there is actually a delay in reading and writing, which means there is a inconsistency in reading and writing in a short period of time. This is a side effect of data rendancy
The second point is that data rendancy often reces the efficiency of writing, because data synchronization also consumes resources. If you add two slave libraries, the write efficiency will be affected. The common storage system is to use rendancy to ensure the high availability of dataso the second question, ordinary storage system, can write more
the answer is yes, for example, take this graph as an example:
in fact, MySQL can do a master-slave synchronization of al masters, master-slave synchronization of al masters, two nodes can be written at the same time. If you want to do a multi room multi live data center, in fact, multi room multi live data synchronization. What we should emphasize here is that multi-point writing often leads to the consistency problem of writing conflicts. Take MySQL as an example, suppose that the attribute of a table is self incrementing ID, then the data in the database is 1234 now. If one of the nodes writes and inserts a piece of data, it may become 5, and then these 5 pieces of data are synchronized to another master node, Before synchronization, if another write node inserts a piece of data, a piece of data with self incrementing ID of 5 will be generated. Then, after the generation, synchronize to another node, and the synchronized data will conflict with the two local 5's after it arrives, which will lead to synchronization failure and write consistency conflict. This problem will occur in the case of multi-point writing
how to ensure consistency in multi-point writing

Hello, thank you
How can enterprises establish their own blockchain
with the popularity of various currency transactions, the development of the exchange instry has been promoted. As Xiao, who wants to cross instry, how to establish a blockchain exchange development company? Chain soft network summarizes the following points for you
2. Check the country's regulations and compliance requirements
almost all governments require entities involved in currency exchange business to comply with the "know your customer" (KYC) specification. KYC is a process for an enterprise to verify the identity of its customers through the ID card or passport issued by the government. The main purpose here is to prevent money laundering. Ensure compliance with KYC specifications in your country / region and integration of appropriate customer verification proceres in your exchange
3. Working with banks or payment processors
you need to work with banks or payment providers to process payments in legal tender. You can choose a trustworthy bank with lots of online facilities
4. Create liquidity in your exchange
any exchange needs liquidity to operate successfully. Customers are hesitant to place orders or even deposit money unless they see the full order and transaction activity. New transactions will naturally encounter liquidity problems
5. Ensure high-level security of trading and customer data
any exchange development company needs first-class security to ensure that the funds of exchange operators and traders are safe. This should also apply to your customers' private data, including their KYC details and bank account information. Over the years, the unnoticed GOx vulnerability resulted in the theft of nearly 1% of the total number of bitcoins in circulation at that time. According to chain soft network, between 2009 and 2019, one third of all bitcoin exchanges were hacked. Therefore, security must be the first priority in your transaction
Finally, customer support is another important part of a successful exchange. Staff are required to approve KYC requests, answer customer complaints, process deposits and withdraw legal tender, etc. A fast customer support mechanism ensures that your customers start trading from the date of signing and generate revenue for your exchangeI hope it can help you to solve the related problems. For more details, please feel free to consult and discuss< br />
the hypervessel platform developed by IBM China Research Institute provides a blockchain development and testing environment for blockchain enthusiasts and developers. Through this platform, users can create a multi node blockchain based on hyperledger fabric free of charge and quickly, and play smart contracts on their own chains
of course, decent, a foreign decentralized content sharing platform, can also be created.
1. Asia and the Middle East will actively promote blockchain
2. Network security requirements will drive the popularization of blockchain
3 - all instries will fully invest in blockchain application technology
4 - automation and privatization are coming.
in order to let people visit their own website, domain name is essential. Domain names should be as short and easy to remember as possible, such as. Top domain names. Of course, there are not many easy to remember and characteristic domain names now. You need to consider it yourself, as long as you think there are certain rules or it is convenient for users to remember
Second, space
to build a website, there must be a space, that is, a place to store the website. For indivial users, it is recommended to purchase virtual host. When purchasing a virtual host, you need to see its service, speed, response time, etc. Generally, you can choose a well-known service provider
note: at present, the domestic service providers with better domain name and space, such as alicloud, Western Digital and China data, are very good choices< Third, the website program
of course, the website program is ready-made, because indivials do not need to start from scratch to develop a website program, and they do not have the strength. Now there is a ready-made website management system on the Internet, and there are many such systems, which can be selected on the basis of their own comprehensive trial
when choosing a website program, we must also consider its versatility and secondary development. For the general bad, not concive to the second phase of development, although powerful, but not recommended, because the site has a certain scale, the need for personalized function design will be very troublesome. In addition, ASP (ASP. Net) is the best choice for the program. PHP and JSP are not very popular in China; Asp.net should be chosen as far as possible between ASP and asp.net. After all, its development trend is based on. Net architecture
Fourth, website design
after choosing the website program, you need to design the website according to your own needs. Generally speaking, if there are professional artists and programmers to modify the nature of the best. But indivial stationmaster may not have this kind of condition, can choose the intelligent station of service provider.
