“…Moreover, blockchain-based social networks can be utilized for combining fog computing to develop security architecture for managing IoT systems by creating tamperproof digital identities in a trustless domain [15]. An additional blockchain contribution to social networks is Tweet-chain [16]. Tweet-chain is a novel social network model-based on blockchain for managing public posts based on Proof of Concept protocol [17] to ensure social transaction security instead of proof of work.…”

Rumors and misleading information detection and prevention still represent a big challenge against social network developers and researchers. Since newsworthy information propagation is a traditional behavior of most of the users in social media, then verifying information credibility and reliability is indeed a vital security requirement for social network platforms. Due to its immutability, security, tamperproof and P2P design, Blockchain as a powerful technology can provide a magical solution to overcome this challenge. This Paper introduces a novel blockchain approach called Proof of Credibility (PoC) for detecting fake news and blocking its propagation in social networks. The functionality of the PoC protocol has been simulated on two datasets of newsworthy tweets collected from different news sources on Twitter. The results clarified a satisfying performance and efficiency of the proposed approach in detecting rumors and blocking its propagation.

“…The document [26] points out that blockchain allows transaction parties to communicate and exchange resources in a peer-to-peer network, which can be traced to the source and save security and audit costs. The documents [27]- [30] propose blockchainbased crowdsourcing application systems suitable for specific purposes respectively, while the document [31] conceptualizes a blockchain-based decentralized framework for crowdsourcing named CrowdBC for general purposes. CrowdBC protects the privacy of users in the block chain, and applies to a large number of incentives tasks, however, it does not consider anonymity and auditing.…”

Recently, crowdsourcing applications for smart cities have become more and more popular due to its higher work efficiency and lower work costs. However, the reasonable task assignment is still one of the important challenges for crowdsourcing. The existing researches on crowdsourcing task assignment focus on the tradeoff between maximizing the utility of platforms and minimizing the cost of requesters, but they lack of the considerations of stability and satisfactory. In this paper, we propose an intelligent multi attributes crowdsourcing task assignment with stability and satisfactory, called TASS. TASS can exploit the multi attributes to solve the stability of the transaction, and adopt the game theory to maximize the satisfaction of both sides during the task assignment. Next, we theoretically prove that the task assignment mechanism is truthfulness, individual rationality, stable and satisfactory assignment, and budget-balanced. Finally, we evaluate the performances of TASS with the state-of-the-art task assignment works. The experimental results show that TASS is better than the state-of-the-art task assignment works in terms of truthfulness, individually rationality, stable and satisfactory assignment, and balanced budget.INDEX TERMS Crowdsourcing, smart city, task assignment, game theory, stable matching.

“…Buccafurri et al 37 proposed an alternative scheme to blockchain based on online social networks to implement crowdsourcing services, but it did not guarantee the confidentiality of the information and there was no incentive mechanism. C Tanas et al 38 utilized the blockchain as a channel to pay rewards, but their proposed scheme cannot defend against some malicious users' attacks, such as the requester's dishonest execution of incentive policy, undermining the fairness of crowdsourcing.…”

The crowdsourcing schemes which utilize the social network to solve complex tasks are an important part of open cooperation over the Internet. Although blockchain-based crowdsourcing schemes have considerable advantages in decentralization and data sharing, there is still a challenge to gurantee the security of crowdsourced-sensitive information and the fairness of crowdsourcing on the blockchain. To this end, this article investigates a crowdsourcing scheme based on blockchain. First, we define the basic requirements of blockchain-based crowdsourcing schemes including fairness, confidentiality, and integrity. And then, using secure hash, commitment, and homomorphic encryption, we propose a blockchain-based secure and fair crowdsourcing scheme, that is, BFC. The analysis results show that our scheme can satisfy the above requirements. Finally, the experimental results show that the computational overhead of the BFC scheme is acceptable to both the requester and the workers. In a word, our proposed crowdsourcing scheme has good expansibility in reality.
