Defi + NFT = decentralized Finance + heterogeneous currency, NFT + defi is to transplant the method of liquidity mining to the field of NFT. At present, meme, sand and rari are typical representatives

the blockchain instry has been trapped in the "self Hi" of the circle, unable to really enter the mass market. Compared with the increment of market and user scale, the Internet instry is a drop in the bucket. Although many projects are emphasizing the novelty of their ideas and advanced technology, few projects are really concerned about how to attract large-scale end users and attach importance to their use experience. Breaking the circle is the only way. The core problem is where to break it? Defi + NFT is a great choice

defi + NFT

the imitation and creativity of the financial field has graally formed the subdivisions of defi, giving birth to the new play of defi + NFT. On the one hand, defi + NFT perfectly solves the problem of insufficient asset supply of defi, on the other hand, it gives the power to creators in an unprecedented way. With the passage of time, more and more artists and innovators will certainly take advantage of the unique attributes of NFT, and then expand them in new ways, giving them stronger, safer and more reliable financial attributes

when the market is crazy, we need to be more rational. Whether it is the popular encryption cat in the early stage or meme in the recent boom, although NFT + defi mode is used to link the encryption field with the physical object, so that the project has the underlying assets, it is essentially a speculative behavior. It is an established fact that the liquidity of NFT assets is poor, which further limits its rising space. In other words, the capacity of the NFT market is very limited. However, in the current situation that the market is graally weakening, defi + NFT may really become the next hot spot

4. ESB is called enterprise service bus. It is a combination of traditional middleware technology, XML, web services and other technologies. ESB provides the most basic connection center in the network, and is a necessary element to build the enterprise nervous system. The emergence of ESB has changed the traditional software architecture, which can provide cheaper solutions than traditional middleware procts. At the same time, it can also eliminate the technical differences between different applications, make different application servers work coordinately, and realize the communication and integration between different services. From the functional point of view, ESB provides event driven and document oriented processing mode, as well as distributed operation management mechanism. It supports content-based routing and filtering, has the ability of complex data transmission, and can provide a series of standard interfaces< First, five basic functions of ESB:
1) metadata management of service: managing the registration, naming and addressing of service in the field of bus
2) transport services: ensure the correct delivery of messages between business processes interconnected through the enterprise bus, and also include content-based routing
3) mediation: provide location transparent routing and location services; Provide a variety of message delivery forms; Support widely used transport protocol
4) multi service integration mode: such as JCA, web service, messaging, adapter, etc.
5) service and event management support: record, measure and monitor data of calling service; It can detect, trigger and distribute events< Second, eight extended functions of ESB: 1) service oriented metadata management: he must understand the two ends of the mediation, that is, the service request and the requester's requirements for the service, as well as the service provider and the description of the service he provides
2) mediation: it must have some mechanism to complete the role of mediation, such as protocol conversion
3) communication: service publishing, subscription, response request, synchronous and asynchronous message, routing and addressing, etc
4) integration: legacy system adapter, service choreography and mapping, protocol transformation, data transformation, enterprise application integration middleware continuity, etc
5) service interaction: service interface definition, replacement of service implementation, service message model, service directory and discovery, etc
6) service security: authentication and authorization, non repudiation and confidentiality, support of security standards, etc
7) service quality: transaction, service delivery, etc
8) service level: performance, availability, etc
the two most frequently mentioned functions in ESB are message transformation and message routing< The emergence of ESB has changed the traditional software architecture, and can provide cheaper solutions than traditional middleware procts. At the same time, it can eliminate the technical differences between different applications, and make different application servers work in coordination, It realizes the communication and integration between different services. From the functional point of view, ESB provides event driven and document oriented processing mode, as well as distributed operation management mechanism. It supports content-based routing and filtering, has the ability of complex data transmission, and can provide a series of standard interfaces< Fourth, the application characteristics of ESB
large scale distributed enterprise applications need relatively simple and practical middleware technology to simplify and unify the increasingly complex and cumbersome enterprise information system platform. Service Oriented Architecture (SOA) is able to connect different functional units of an application through well-defined interfaces and contracts between services. SOA enables users to reuse software and interconnect various resources without restriction. As long as it personnel choose standard interfaces to package old applications and build new applications into services, other application systems can easily use these functional services
the key to support SOA is its messaging architecture enterprise service bus (ESB). ESB is the proct of the combination of traditional middleware technology with XML, web services and other technologies, which is used to realize the accurate, efficient and secure transmission of different messages and information in enterprise applications. The emergence of ESB has changed the traditional software architecture, and can provide cheaper solutions than traditional middleware procts. At the same time, it can also eliminate the technical differences between different applications, make different application services work in coordination, and realize the communication and integration between different services. ESB has a very wide range of uses in different fields:
telecommunication field: ESB can fully support the application integration concept of OSS in telecommunication instry. It is an ideal carrier level application software platform
power sector: ESB can fully support the data integration concept of EMS in power instry, and is an ideal data exchange platform for SCADA system
financial sector: ESB can support the process integration concept of business processing platform between banks and enterprises in an all-round way, and is an ideal B2B transaction support platform
E-government: ESB can fully support the platform realization of e-government application software business foundation platform, information sharing and exchange platform, decision analysis support platform and government portal< Five kinds of ESB structure
ESB provides an open and standard based message mechanism, which can complete the interoperability between coarse-grained applications (services) and other components through simple standard adapters and interfaces, and can meet the integration requirements of large heterogeneous enterprise environment. It allows generations of technologies to interoperate without changing the existing infrastructure
by using ESB, the existing system of an enterprise can have a new service interface in a seamless and non intrusive way without changing the code, and can support any standard in the deployment environment. More importantly, the ESB (which is responsible for transforming business logic and data format between many services) is separated from the service logic, so that different applications can use the same service at the same time, and there is no need to change the service code when the application or data changes

4. Implementation of ESB by servicemix
servicemix is an open source ESB (Enterprise Service Bus) project based on JBI (JSR 208) syntax rules and APIs. Servicemix is a JBI based ESB. It is an open source ESB and SOA toolkit based on JBI semantics and API, which is released under Apache license. It is a lightweight ESB implementation and easy to use as an embedded ESB; The support of spring technology is integrated; It can run on client or server; It can be used as an independent ESB provider or as a service component of another ESB; It can be used in Java se or Java EE server; Servicemix is fully integrated with Apache Geronimo and JBoss server, and JBI components and services can be directly deployed in Apache Geronimo server. Java business integration (JBI) technical specification defines the core and architecture of SOA service-oriented integration. It standardizes the common message path architecture, service engine and bundled plug-in interface, and composite service description mechanism, so that multiple services can be combined into a single executable and auditable unit of work. JBI and servicemix diagram JBI is not an interface designed for developers. To be more precise, it is an integrated system and a series of interfaces for integrators in JBI container. So people can assemble all the parts they need to make an overall solution. For example, in theory, you can assemble an infrastructure from a BPEL engine, EJB container, or data transfer proct, and integrate it appropriately. Servicemix contains a complete JBI container, which supports all the functional requirements of JBI specification: l standardizing message service and routing l JBI managing beans (MBeans) l ant tasks managed and installed by components l full support for JBI deployment units, Support hot deployment of JBI components

At the same time, it can also eliminate the technical differences between different applications, make different application servers work in coordination, and realize the communication and integration between different services. From the functional point of view, ESB provides event driven and document oriented processing mode, as well as distributed operation management mechanism. It supports content-based routing and filtering, has the ability of complex data transmission, and can provide a series of standard interfaces< The five basic functions of ESB are as follows:
1) metadata management of services: registration, naming and addressing management of services within the scope of bus
2) transport service: it is necessary to ensure the correct delivery of messages between business processes interconnected through the enterprise bus, and transport also includes content-based routing function
3) mediation: provide location transparent service routing and location services; Multiple message delivery forms; Support widely used transport protocol
4) multiple service integration methods: such as JCA, web services, messaging, adapter, etc.
5) service and event management support: such as service call recording, measurement and monitoring data; It can detect, trigger and distribute events
eight extended functions of ESB:
1) service oriented metadata management: he must understand the two ends mediated by him, that is, the service request and the requester's requirements for the service, as well as the service provider and the description of the service he provides
2) mediation: it must have some mechanism to complete the role of mediation, such as protocol conversion
3) communication: service publishing, subscription, response request, synchronous and asynchronous message, routing and addressing, etc
4) integration: legacy system adapter, service choreography and mapping, protocol transformation, data transformation, continuity of enterprise application integration middleware, etc
5) service interaction: service interface definition, replacement of service implementation, service message model, service directory and discovery, etc
6) service security: authentication and authorization, non repudiation and confidentiality, support of security standards, etc
7) service quality: transaction, service delivery, etc
8) service level: performance, availability, etc
the two most frequently mentioned functions in ESB are message transformation and message routing< br />

6. There is no universally accepted standard for ESB. The function of ESB is to help integrate services, not to participate in business logic. Popular point: ESB is the intermediary to realize intelligent integration and management among services in SOA architecture
the concept of enterprise service bus (ESB) is developed from service oriented architecture (SOA).
ESB has two basic functions: metadata management and mediation. As an important part of SOA, ESB also undertakes the important task of how to connect the existing business services in the enterprise architecture to the bus, which we call adapter function
ESB should be built on a perfect SOA architecture and do what it should do service integration. As for how to integrate, you should consider which SOA infrastructure is available to you according to your context, and then implement your ESB design based on SOA infrastructure
at a higher level, ESB also provides functions such as service proxy, protocol conversion, etc., which we call ESB usage pattern
as for why to use ESB, there must be many systems in an enterprise, but the data transmission format and transmission protocol between operating systems are not the same. In this case, the call between different systems must be very complex, and the maintenance cost of the interface must be very large. At this time, the ESB is very necessary to mediate. There are also many ESB procts, such as IBM's WebSphere message broker, Oracle's OSB, and wso2's synapse / wso2 ESB. IBM's characteristic is to simplify the development mode, rece the threshold of use, rece the probability of use, and the development mode will change from bottom-up to top-down. IBM also has many agents in China, such as Beijing Shenma and Shanghai Dehui.
