  Traditional distributed transaction processing (TP) systems, such as
replicated databases, faced difficulties in getting wide adoption for scenarios
of enterprise integration due to the level of mutual trust required.
Ironically, public blockchains, which promised to solve the problem of mutual
trust in collaborative processes, suffer from issues like scalability,
probabilistic transaction finality, and lack of data confidentiality. To tackle
these issues, permissioned blockchains were introduced as an alternative
approach combining the positives of the two worlds and avoiding their
drawbacks. However, no sufficient analysis has been done to emphasize their
actual capabilities regarding TP. In this paper, we identify a suitable
collection of TP criteria to analyze permissioned blockchains and apply them to
a prominent set of these systems. Finally, we compare the derived properties
and provide general conclusions.
