Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.
Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

Crowdsourcing clinical research utilizing blockchain-based incentivization systems by Phillip Olla, Lauren K. Elliott, Mustafa T. Abumeeiz, Joshua Zegrean, Vijay Rajasekar Abstract: During the ongoing pandemic, the organisation of clinical trials has proven problematic for many researchers. Recruitment challenges aside, the need to maintain participant safety has made it difficult for researchers to enrol a suitable number of participants. As such, many researchers have had to adopt a virtual approach to conducting clinical trials. Virtual clinical trials have the potential to enable mass enrolment of participants in studies, ultimately crowdsourcing clinical data. However, there remains a need to encourage participation in studies and protect data. To overcome this, an incentivisation system which can be trusted by participants and researchers has been discussed in this paper. Titled Cashish, this system is a blockchain-based incentivisation network that encourages participant recruitment by awarding cryptocurrency that can be used in marketplace transactions. Blockchain technology eliminates the need for trust-based systems and allows researchers to be transparent with participants while participants remain anonymous. Keywords: blockchain; cryptocurrency; cannabis research; virtual clinical trials. DOI: 10.1504/IJBC.2021.10042090
Decentralized Domain Authentication by Shehyaaz Khan Nayazi, Mohammed Sufiyan Aman, Shakshi Pandey, Riyanchhi Agrawal, Namratha M Abstract: Transport layer security protocols ensure secure and encrypted communications on the internet. The security of TLS protocols relies on properly validating digital certificates containing the public keys of domains during the handshake authentication. These certificates are issued by certificate authorities (CAs). However, mis-issued certificates have been used to attack users. To monitor CA behaviour, certificate transparency (CT) and a decentralised system, instant karma public key infrastructure (IKP) were proposed, however, they do not tackle domain misbehaviour. Based on CT and
IKP, a decentralised system is proposed using the Ethereum framework to handle the misbehaviour of domains and enhance the security of TLS. The proposed system utilises CT logs to detect and respond to domain misbehaviour.
