In this research we aim to determine what positive and negative factors influence blockchain adoption in the Netherlands. We achieve this by interviewing eight blockchain experts and by analysing the factors that are top of mind among these experts.We anticipated that the majority of the experts would mention the technological advantages of blockchain as a prevalent factor that drives adoption. Surprisingly, our research suggests a disconnect between blockchain adoption and its technological advantages. By contrast, a prevalent factor that drives blockchain adoption is competitive pressure, according to the majority of experts. Also, based on the analysis of the interviews we introduce two new drivers, 1. Being willing to collaborate, and 2. Problem match. We also identify two factors that are an impediment for blockchain adoption according to the majority of the experts, 1. Lack of regulation on blockchain, and 2. Lack of knowledge about blockchain properties by non-experts. Our work is useful as organisations and governments may want to reconsider their rationale for adopting blockchain. If a rationale exists for adopting blockchain then these organisations and governments can focus on the impediments of blockchain adoption.","PeriodicalId":218474,"journal":{"name":"2020 Second International Conference on Blockchain Computing and Applications (BCCA)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126213323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The heterogeneity and high-mobility in smart city systems have arisen the need for the mobile ad-hoc network (MANET). Ad hoc On-Demand Distance Vector (AODV) emerges as an efficient routing protocol in MANET is based on the less overhead by reducing message exchange with limited information. However, this creates a weakness as nodes have limited knowledge about other nodes’ identity inside the path beyond the neighboring node (node in transmission range). That prevents the participant from authenticating others and has limited capability to check the integrity of the exchanged information. To accomplish this, it requires a further exchange of messages that defeat the AODV main principle and causes extra overhead that drains the portable devices’ limited battery energy inside the network. This paper used the blockchain concept to generate a hashed identifier from the node’s IP and passed between nodes inside the path during the route discovery that provides assurance about the identity of the node and keeps the integrity of the exchanged information. Additionally, Simulation results using (Riverbed/Opnet) of the attack scenario show that the proposed algorithm prevents impersonation and black-hole attacks by eliminating the path that involves malicious nodes with a (4 millisecond) increase in route discovery time.","PeriodicalId":218474,"journal":{"name":"2020 Second International Conference on Blockchain Computing and Applications (BCCA)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128423513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The social network connects two devices if they have a common owner or both manufactured by the same company or they are situated at the same location etc. Centralized SIoT platforms have security and privacy problems. We advance the state of art in SIoT as we have developed a decentralized SIoT platform. In a decentralized SIoT platform, the services provided by a device is only known to its neighbours. Due to such characteristics of decentralized SIoT platform, there are several challenges in designing it, such as verification of social neighbourhood, privacy-preserving search in SIoTs, and scalability of SIoT platform. In this paper, we propose a blockchain-based SIoT platform to mitigate these problems. Our main contributions are: We developed a decentralized SIoT platform that allows secure privacy-preserving method to verify social neighbourhood a device, we developed a protocol to find devices in the decentralized SIoT and we developed a high scale decentralized SIoT platform using blockchain offline channels. We prove the proposed decentralized SIoT platform is privacy-preserving, secure, and scalable.","PeriodicalId":218474,"journal":{"name":"2020 Second International Conference on Blockchain Computing and Applications (BCCA)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126976494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
