Nonfungible Tokens: Constructing Value Systems in Parallel Societies

Welcome to the fifth issue of Ieee Transactions on Computational Social Systems (TCSS) of 2021. As usual, we would like to share some great news first. Since April 2021, IEEE TCSS has been added to the Science Citation Index Expanded (SCIE) database in Clarivate Web of Science. We are excited to report that all TCSS articles published since 2018 have been backtracked and indexed by SCIE.
