日本データベース学会の皆様 京都大学の曹です。 お世話になっております。 2つブロックチェーンに関するSpecial IssuesのCFPを送りいたします。 *Sensors*: Special Issue "Emerging Blockchain Technology Solutions for Real-world Applications (EBTSRA)" https://www.mdpi.com/journal/sensors/special_issues/EBTSRA *Peer-to-Peer Networking and Applications (PPNA)*: Special Issue on Blockchain for Peer-to-Peer Computing https://www.springer.com/journal/12083/updates/17751820 論文提出の〆切は2020年10月末です。 投稿をご検討をよろしくお願いいたします。 曹洋 ---------------------- Call for Papers 1: *Sensors*: Special Issue "Emerging Blockchain Technology Solutions for Real-world Applications (EBTSRA)" https://www.mdpi.com/journal/sensors/special_issues/EBTSRA Deadline for manuscript submissions: 31 October 2020. This Special Issue comprises papers presented at the 2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring) Workshop on Emerging Blockchain Technology Solutions for Real-World Applications (EBTSRA), held 25–28 May 2020 in Antwerp, Belgium. This semi-annual flagship conference of the IEEE Vehicular Technology Society will bring together individuals from academia, government, and industry to discuss and exchange ideas in the fields of wireless, mobile, and vehicular technology. *This Special Issue is also open to other submissions. * A blockchain is a secured, shared, and distributed ledger that facilitates the process of recording and tracking resources without the need of a centralized trusted authority. The technology is scalable and robust, and all participant nodes provide resources fairly, which alleviates many-to-one traffic flow bottlenecks. This technique decreases traffic delays and defeats errors due to a single point of failure. However, blockchain is still a nascent technology and as such there are challenges for the wide adoption of blockchain as a new enterprise and operational layer. These challenges are around scalability, interoperability, standards, privacy, security, governance, and consensus mechanisms, which need to be defined and validated for real-world applications. This workshop opens a forum to present the recent research work related to blockchain-based technologies (e.g. smart contracts, threat and attack models, and incentive mechanisms). Moreover, research on other aspects inherently present in blockchain-based applications, like the internet of things, smart grids, e-health, logistics, etc. are also invited in this workshop. This Special Issue seeks original unpublished papers focusing on theoretical analysis, emerging applications, novel system architecture construction and design, experimental studies, and social impacts of blockchain. Both review/survey papers and technical papers are encouraged. Topic areas include, but are not limited to, the following: Blockchain in 5G technologies; Blockchain in IoT; Blockchain in information-centric networking; Blockchain in smart grids; Blockchain in artificial intelligence; Blockchain in networking and edge/fog/cloud technologies; Blockchain in e-health; Blockchain in decentralized financing and payments; Blockchain in social networking; Blockchain in agriculture; Blockchain in autonomous vehicles; Blockchain in mobile cellular networks; Blockchain standardization; Blockchain tools, simulators and test-bed; Private blockchain systems; Decentralized storage in blockchain; Security, privacy, and trust of blockchain and distributed ledger technologies; Secure smart contracts; Consensus mechanisms. We are proud to announce our agreement with MDPI to publish a Special Issue on Emerging Blockchain Technology Solutions for Real-World Applications (EBTSRA) and cordially invite all researchers to publish a full paper in this Special Issue of the journal Sensors (ISSN1424-8220; *Impact Factor 3.031*; https://www.mdpi.com/journal/sensors) published online by MDPI, Switzerland. According to the publishing rules regarding the extended version of conference papers, 1) Title and Abstract should be substantially different with that of conference paper so that they can be differentiated in various databases; 2) 50% new data should be added to make it a real and complete journal paper; 3) The conference proceedings should be mentioned and discussed in the Introduction section; 4) Conference proceedings should be submitted together as supplementary information. Manuscript Submission Information Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website. Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI. Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions. ---------------------- Call for Papers 2: *Peer-to-Peer Networking and Applications (PPNA)*: Special Issue on Blockchain for Peer-to-Peer Computing https://www.springer.com/journal/12083/updates/17751820 Paper submission deadline: *30 Oct. 2020* First-round notification: 15 Dec. 2020 Revision deadline: 15 Jan. 2021 Final decision notification: 15 Feb. 2021 Aim and Scope A Blockchain is a secured, shared and distributed ledger that facilitates the process of recording and tracking resources without the need of a centralized trusted authority. The technology is scalable and robust and all participant nodes provide resources in a fair manner, which alleviates many-to-one traffic flow bottlenecks. This technique decreases traffic delays and defeats errors due to a single point of failure. However, blockchain is still a nascent technology and as such there are challenges for the wide adoption of blockchain as a new enterprise and operational layer. These challenges are around scalability, interoperability, standards, privacy, security, governance and consensus mechanisms that need to be defined and validated for peer-to-peer computing. This special issue opens a forum to present the recent research work related to blockchain-based technologies, e.g. smart contracts, threat and attack models, and incentive mechanisms. Moreover, research on other aspects inherently present in blockchain-based applications, like the Internet of things, smart grid, e-health, logistics, etc. are also invited to this special issue.
