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 </span><span style="FONT-SIZE: 12pt; TEXT-DECORATION: none; FONT-FAMILY: Arial; FONT-VARIANT: normal; VERTICAL-ALIGN: baseline; WHITE-SPACE: pre-wrap; FONT-WEIGHT: 400; COLOR: #2b2b2b; FONT-STYLE: normal; BACKGROUND-COLOR: transparent">within

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.</span></p>

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.</span></p>
