Query: When Distributed Ledger Technology meets Internet of Things -- Benefits
  and Challenges   There is a growing interest from both the academia and industry to employ
distributed ledger technology in the Internet-of-Things domain for addressing
security-related and performance challenges. Distributed ledger technology
enables non-trusted entities to communicate and reach consensus in a fully
distributed manner through a cryptographically secure and immutable ledger.
However, significant challenges arise mainly related to transaction processing
speed and user privacy. This work explores the interplay between
Internet-of-Things and distributed ledger technology, analysing the fundamental
characteristics of this technology and discussing the related benefits and
challenges.
