“…The cross-chain workflow model proposed in the article [ 11 ] defined the cross-chain process as a cross-chain workflow, which abstracted the cross-chain process with similar characteristics and realized the management of cross-chain workflow with the relay chain as the centre. According to the experimental results obtained in this paper, because of the involvement of the relay chain, the burden of inter-chain interactions was increased and the average cross-chain time was 10.47 s. The management system based on cross-chain switching designed by Tan et al [ 14 ] introduced public key encryption with a keyword search to improve the scalability of blockchain applications in vehicular ad hoc networks. An average cross-chain exchange performance of 10.5 s was obtained in the experiment built in an actual blockchain environment.…”

“…More attention should have been paid to the loyalty of nodes and a poor focus on avoiding security risks of transmission outside blockchains. The authors in [ 14 ] described a cross-chain exchange-based management system to improve the scalability of blockchain applications in an onboard self-organizing network by introducing public key encryption with a keyword search.…”

Cross-chain interoperability can expand the ability of data interaction and value circulation between different blockchains, especially the value interaction and information sharing between industry consortium blockchains. However, some current public blockchain cross-chain technologies or data migration schemes between consortium blockchains need help to meet the consortium blockchain requirements for efficient two-way data interaction. The critical issue to solve in cross-chain technology is improving the efficiency of cross-chain exchange while ensuring the security of data transmission outside the consortium blockchain. In this article, we design a cross-chain architecture based on blockchain oracle technology. Then, we propose a bidirectional information cross-chain interaction approach (CCIO) based on the former architecture, we novelly improve three traditional blockchain oracle patterns, and we combine a mixture of symmetric and asymmetric keys to encrypt private information to ensure cross-chain data security. The experimental results demonstrate that the proposed CCIO approach can achieve efficient and secure two-way cross-chain data interactions and better meet the application needs of large-scale consortium blockchains.

“…These atomic swaps are also known as atomic crosschain trading based on smart contracts, and they allow users to trade their coins directly from their crypto wallet. So atomic swaps are, essentially, peer-to-peer trades across different blockchains [107], [108]. Atomic swap protocols are designed to prevent any of the involved parties from cheating.…”

Recently, Blockchain-based applications have become immensely popular because of limited reliance on a single entity, unlike a centralized system. However, reaching a consensus among blockchain networks is a challenging and vital aspect of blockchain-based applications. There are various types of blockchain networks for different kinds of application scenarios. Among all of them, the consensus algorithm is the most crucial part of reaching an agreement in the complex blockchain network. Over the years, researchers have focused on dealing with the challenges like distributed computing, storage, transaction speed, security, validity, interoperability, and many more. However, only some of them are appropriate for all domains. Therefore, this paper presents an extensive study of different types of consensus protocols used in existing blockchain solutions with the strength and limitations of each algorithm. We also provide an inherent comparison among different algorithms to understand consensus protocol selection better. Moreover, we investigate operational and interoperability issues in existing blockchain-based applications to understand challenges and provide recommendations for future developers.INDEX TERMS Blockchain, consensus algorithm, interoperability, cross-chain transactions, architecture, operational issues, applications, research directions. I. INTRODUCTIONT HE blockchain concept was first introduced by Haber and Stornetta [1], which is considered one of the technologies with the most potential. After that the introduction of Bitcoin by Nakamoto [2], it has attracted intense attention from all over the world. In Blockchain systems, different cryptographic protocols, like hash functions, digital signatures, etc., are used to maintain the authenticity and security of the data. Blockchain is a distributed ledger system that keeps data secure from unauthorized access. Blockchain technology allows users to add, view, and validate transactions to the distributed ledger. These transactions often take place with the consent of all involved users. Blockchain uses a consensus mechanism to ensure that all transactions are accurate.In a trustless environment, blockchain provides users with desirable qualities like decentralization, autonomy, integrity, immutability, verification, fault-tolerance, anonymity, auditability, and transparency, which have received significant academic and industrial attention recently years [3]-[6]. However, the blockchain system is trustless and ensures blockchain-enabled trust through other cryptographic peerto-peer communication in the decentralized network. Further verification and validation mechanisms are employed

TCA: A Trusted Collaborative Anonymity Construction Scheme for Location Privacy Protection in VANETs

As location-based services (LBS) are widely used in vehicular ad-hoc networks (VANETs), location privacy has become an utmost concern. Spatial cloaking is a popular location privacy protection approach, which uses a cloaking area containing k-1 collaborative vehicles (CVs) to replace the real location of the requested vehicle (RV). However, all CVs are assumed as honest in k-anonymity, and thus giving opportunities for dishonest CVs to submit false location information during the cloaking area construction. Attackers could exploit dishonest CVs' false location information to speculate the real location of RV. To suppress this threat, an edge-assisted Trusted Collaborative Anonymity construction scheme called TCA is proposed with trust mechanism. From the design idea of trusted observations within variable radius r, the trust value is not only utilized to select honest CVs to construct a cloaking area by restricting r's search range but also used to verify false location information from dishonest CVs. In order to obtain the variable radius r of searching CVs, a multiple linear regression model is established based on the privacy level and service quality of RV. By using the above approaches, the trust relationship among vehicles can be predicted, and the most suitable CVs can be selected according to RV's preference, so as to construct the trusted cloaking area. Moreover, to deal with the massive trust value calculation brought by large quantities of LBS requests, edge computing is employed during the trust evaluation. The performance analysis indicates that the malicious response of TCA is only 22% of the collaborative anonymity construction scheme without trust mechanism, and the location privacy leakage is about 32% of the traditional Enhanced Location Privacy Preserving (ELPP) scheme.
