3.1 assumptions
This work assumes that DAPP and Web3 are hosted in multi -missile data centers. The targeted environment focuses on the output applications, for example, Oracle applications outside the series, and light applications that have been implemented outside the series in Web3. This means that services such as Blockchain as a (Baas) service or auditor as a (VAAS) service is located outside the scope of this work. Moreover, we assume that DAPP and Web3 applications can be implemented by container containers. In the future, the frame can be extended to support the wide back interface services, such as the virtual system counterparts. We also assume that services are called with API calls through API gates. After protesting, the DAPP implementation may create Blockchain transactions, for example, update the status/status on the chain. However, it is not required that every time a job is called, it must include any reaction on the chain. DAPP may perform other DAPP functions. The DAPP or Web3 application may be turned on by updating the status on the chain, for example, running the Web3 function after confirming the payment on the chain. For DAPP and Web3 applications, IAM depends on Blockchain identities. This means that if the execution of the function requires permission, the access control depends on the Blockchain portfolio accounts. The environment aims to support DAPP and Web3 applications in a multi -episode context. We assume that there are cross bridges to exchange states and exchange digital assets via Blockchains (for example, [Robinson(2021)]) Like bills across the chain of services (for example, [Herlihy(2018), Pillai et al.(2022)]). The cross bridges are supposed to be safe[2]. There is a confidence management plan for the ecosystems. For example, a stake using symbols may be needed for DAPP/Web3 service providers (for example, API gate service provider, DAPP Provider) in the environment. If the service provider is offended, his share may be reduced. Cloud service providers are supposed to be somewhat reliable, which means that they will often adhere to the level of service level. Cloud service providers will not act harmful and attack DAPP or WEB3 hosted applications such as the launch of Denial of Service. Although this work focuses on black multi -settings, the work can be extended in the future to a hybrid environment that includes both multi -missile databases and the user contributed to computing resources (the subject of future research).
3.2 Comprehensive architecture for Devas
Figure 1 provides an overview of the system structure. The frame avoids the central component, and it is not completely central in the sense that there is no single entity that can control a major component of the system. Management is achieved using specific Blockchain. On the high level, the exact nature of this Blockchain, for example the type of consensus protocol, subsidized smart nodes, is not related because one can imagine different applications to match specific requirements in certain contexts. We assume the presence of Blockchain management. Blockchain is connected to other superstructures using the bridges of the crossed chain to enable multi -power support so that DAPP and Web3 applications can be managed based on different groups of Blockchains by Blockchain individual management. Under this frame, a DAPP or Web3 function can be called by users of multiple groups. This Blockchain management is also responsible for bills. The bills accumulate for each user. After a period of time, he can send a request for bills to Blockchain opposite to charge users for services. For example, if the user is affiliated with Blockchain A and the user assembly the total $ 100 (for example, bills in stable metal currencies) within a week. Management series can use the cross bridge and cross -transactions to charge the user on Blockchain A.
Framework supports a network of API gates hosted in multi -fluid setting. Non -central API gates. The system may require that the portal service providers have stakeholders. If the gate supplier is harmful, its share can be reduced. The mechanism is similar to how to manage the labia in groups of proof. The portal contract forms a distributed network network. API calls can be directed between the gates.
DAPPS and Web3 applications are performed upon request using FAAS containers (function as a service). There are many benefits using this infrastructure. First, the container -based FAAS is not to know the cloud, and it achieves a high ability to transport. Second, he is safe and graceful with strong isolation of containers. Third, there is no need to plan the node capacity and there is no need to manage the server contract. Fourth, the system can easily expand with a container -based scaling. Fifth, there is no waste of resources because bills depend on payment.
As shown in Figure 1, Blockchain provides management main services such as registration of the end of the application programming interface, identity management, support for the interim operation between the cloud and Blockchain, control and licensing for applications interface calls, invoices management, support and registration support (see details In the next section). In the end, it should be noted that the design does not carry any assumption of the hosting environment in Blockchain itself.
3.3 The components of the prefaas preliminary model
In this specific work, we choose Hyperledger Besu [Besu([n. d.]]Also, management Blockchain. It is important to highlight that the general design is not limited to Besu or Hyperledger. Besu supports EVM and smart contracts. It can be applied to the general and private Blockchain network. For FAAS, we use OpenFaaas [OpenFaaS([n. d.])]. There are many platforms for FAAS and Computing without a server (for example, [OpenWhisk([n. d.]), Without success ([n. d.]), Faster ([n. d.]))). OpenFaaas is chosen for clarification purposes. This means that our framework does not rule out the adoption of other FAAS platforms. OpenFaaas supports FAAS containers using kubernetes. It is easy for developers to publish microservices that depend on Multi-Cloud using OpenFaaas. Applications can be filled in an OCI compatible image for publication. The platform is extendable and customized. The end points are largely developed with automatic division.
