Production consumer mode blockchain

1. There are many applications that have been implemented in blockchain. Although they can not be adapted to all application scenarios, there are many applications on the market, such as micro three cloud. Their blockchain integral system has many application scenarios such as e-commerce and content payment, and has been certified by many businesses.

2. I'd like to know about blockchain. It's said that blockchain can create ten times the value of the Internet, so I'd like to ask you to use blockchain to create 1 million value for me. Anyway, it's just a small amount of money for blockchain.

3. Newton blockchain and Newton based e-commerce
Newton is a social economic infrastructure that provides governance, collaboration and incentive. Newton, through the basic technology, protocol layer and application layer blockchain technology architecture, has built a social economy managed by non-profit foundations, replacing the traditional economy managed by closed-end for-profit companies, and implemented the vision of "everyone should benefit from the economy". Compared with the traditional business, the transaction cost of social economy is greatly reced because there is no commercial intermediary
the man-machine community created by Newton, which is composed of human and machine nodes, can be calculated as newforce according to the degree of contribution to the ecology, so as to obtain the corresponding new incentive according to the newforce value, so as to ensure that the economic beneficiaries cover the service providers, consumers and other ecological participants. Newton planned the application scenarios of chain retail, supply chain, agriculture, public welfare, games and self finance to serve the real economy
newmall, a chain retail platform to be launched in 2019, is Newton's first commercial application scenario. Compared with traditional e-commerce, on the chain retail platform, participants including but not limited to shopping, browsing advertising, promotion and other behaviors can get the incentive of new. Participants own their own data to prevent the disclosure of consumption information. For businesses, the platform cost will be greatly reced. Moreover, Newton is initiated by a non-profit organization. Newmall will not retain any platform fees as profits, and will encourage the participants in the form of new in various ways.

4. The application of blockchain and logistics supply chain is now in the landing state, and the blockchain + mode is very popular. Changsha Information Instry Park has built a service platform project of SMIC blockchain, which is for enterprises to collect information on the chain, and to build a blockchain instry alliance.

5. The analysis of jinwowo group, the core value of blockchain application in social field, believes that: let users control data by themselves and prevent privacy leakage
the purpose of the application of blockchain technology in the social field is to change the control of social networks from centralized companies to indivials, realize the change from centralization to decentralization, and make the control of data firmly in the hands of users
in the future, jinwowo will continue to tap the value of blockchain technology in the commercial field, give full play to the advantages of big data services, add value to user behavior, break the ice for the development of small and medium-sized enterprises, and build a real, efficient, safe and honest Internet community of destiny.

6. The procer consumer model says that the input and output of a business process are decoupled into two parts. Asynchronous operation
has no theoretical relationship with distributed operation. Distributed operation only means that the business behavior contains multiple points participating at the same time, so their relationship can be synchronous or asynchronous

7. Design patterns can be regarded as the experience summary and sublimation in OO (object-oriented) programming. The common design patterns are 21 classic ones. The purpose of using design patterns is to make your code more extensible and reusable
so if the procer consumer model can make your code easy to expand and reuse, it can be considered as a better design pattern
of course, the advantages and disadvantages of procer and consumer models can be referred to: http://tech.sina.com.cn/s/2009-07-30/00491005541.shtml

8. C + + multithreading can also use UNIX C library function, pthread_ mutex_ t,pthread_ create,pthread_ cond_ t,pthread_ detach,pthread_ mutex_ Lock / unlock, etc. When using multithreading, you need to create a thread first and use pthread_ Create, you can make the main thread wait for the child thread to use pthread_ You can also separate threads and use pthread_ detach The biggest problem in the use of threads is the synchronization problem. Generally, the proction consumer model is used for processing, and the condition variable pthread is used_ cond_ t,pthread_ mutex,pthread_ cond_ Wait. Others say that no matter how much it is, it's someone else's. read a book or Google by yourself.

9. Specific business needs to be customized. Your demand is actually a deformed procer consumer realization. For this kind of requirement, the main purpose is to decouple the request from the actual processing process. Generally, the requester is notified asynchronously, which has little to do with whether to use redis or not. The general implementation method is that you need to encapsulate the user's request into a task, and then push the task to the redis queue, and then the back-end worker. PHP can process the task concurrently with multi process and multi thread, and call back the processing result to the requester. The only trouble here is the design of the task, which needs to contain the request information (request content, requester ID, etc.)
