Call for Papers: Special issue on Blockchain Technology and Applications Aims and scope In recent years, the blockchain technology is having an ever growing popularity, in particular for what concerns its application cryptocurrencies. As a matter of fact, Bitcoin is currently the most known application of the blockchain technology, and a number of alternative cryptocurrencies have been defined and are currently used, e.g., Litecoin or Monero. However, the application of blockchain is not limited to cryptocurrencies. The immutability of the transactions and the absence of trusted intermediaries make the blockchain technology suitable to be applied in many research and business scenarios, and a number of blockchains are currently available on the market. For instance, permissioned blockchains are meant to address those business scenarios where transactions needs to be private, and their processing must be executed within a predefined group of known participants. Moreover, some blockchains (such as Ethereum or Quorum) allow the execution of Smart Contracts, thus paving the way to a very large plethora of new interesting applications of the technology in several fields, such as: Internet of Things, Cyber Physical Systems, Edge Computing, Supply Chain Management, Social Networks, and many others. The aim of this special issue is to gather latest research results concerning blockchain technology and its application on relevant scenarios, such as the ones previously listed. Researchers, experts, and scholars from both industry and academia are encouraged to present their recent achievements and research directions in this area.
