Our main contribution is a fully decentralized architecture that combines blockchain and traditional distributed database to gain additional features such as efficient query and retrieval of metadata stored on the blockchain.doi:10.1007/978-3-319-76451-1_33Obaro Odiete...
Blockchain technology is increasingly being used in the internet of things (BCoT: Blockchain for IoT) to ensure the security and reliability of data exchanged between connected devices. There are several generic blockchain architectures for IoT that differ in their network and consensus characteristics...

More details about the blockchain architecture can be found in [[5], [7]]. Blockchain has also provided a technology where the concept of smart contract can be materialized. In general terms, a smart contract refers to the computer protocols or programs that allow a contract to be ...
This article presents design principles, artifacts and code samples for building blockchain applications using a microservice architecture style and deploying them on the Azure Blockchain platform.

Blockchain-based and Intelligence-assisted solutions for 5G-related drone network security concerns have also been discussed. We also highlight the utility of drones in present-day Smart City Infrastructure, ranging across multitudes of applications, as well as in the Precision Agriculture domain and ...
通过将一个普通的 API 作为所有控制器设备的前端, 可以抽象出不同设备类型和微服务分区的复杂性。 然后, 该设备可以转换为服务(device-as-a-service) , 并被其他服务使用。 基于网格数据的类型, 网关可以调用单独的事件和查询处理服务(类似于 CQRS 架构) , 该服务可以更新和检索在"事件存储"中持久存在的对象的...
Moreover, the security vulnerability because of centralization is an easy target for Distributed denial-of- service (DDoS) attacks. Additionally, to ensure data integrity presence of publically verifiable audits without involving a TTP is desirable. In this context, blockchain can mitigate security ...
The Service Bus message also requires:userChainIdentifier: The blockchain address of the user or device that was created on the blockchain network. contractLedgerIdentifier: The blockchain address of the contract on the ledger. workflowFunctionName: The name of the smart contract’s function to ...
introduce our framework in three parts: 1) a novel blockchain system architecture MSLShard based on access control; 2) a spectral clustering-based network sharding scheme (SCNS) for edge blockchains; 3) a multi-dimensional subjective logical trust management model (MSLTM) based on blockchain. ...
