Abstract
Blockchain is a relatively novice technology rapidly increasing as a next-generation solution for maintaining digital transactions and record-keeping issues. Blockchain technology can be used in financial services, healthcare facilities, social services, the governmental sector, the Internet of Things (IoT), etc. Regularly any new technologies have some challenges like security risks (threats and vulnerabilities). Among these blockchain challenges is managing the large-scale digital transactional system, which is potentially exposed to a multitude of threats. Thus, this paper introduces the categories of blockchain technologies’ cybersecurity vulnerabilities and some aspects of cybersecurity risk assessment.
