MDPI-BLOC 2019 : MDPI Future Internet Journal - Special Issue on Blockchain: Current Challenges and Future Prospects/Applications

Dear Colleagues,

Blockchain innovates in three simple but powerful directions. First, the way records are kept excludes tempering; second, it assures trust in the transactions amongst strangers; and third, it offers transparency and much greater safety/security than the traditional Internet. Blockchain has been called “the next generation of the internet” and alternatively “the Internet of value”, aiming to revolutionize the Internet of today by exploiting its three breakthrough innovations. There are still problems to be solved and challenges to be overcome, but similar ones were faced in the early 1990s when the Internet was in a comparable stage to that of today’s blockchain.

It is the purpose of this Special Issue to cover all aspects of blockchain technology. Authors are encouraged to submit articles that include existing problems/challenges together with suggestions of how they could be dealt with, as well as covering its revolutionary future prospects and their implications for real-life applications upon which the Special Issue editors have placed special emphasis. The list of topics below is indicative but not exhaustive of the papers to be submitted for possible publication in this Special Issue.
