  The applications of the blockchain technology are still being discov-ered.
When a new potential disruptive technology emerges, there is a tendency to try
to solve every problem with that technology. However, it is still necessary to
determine what approach is the best for each type of application. To find how
distributed ledgers solve existing problems, this study looks for blockchain
frameworks in the academic world. Identifying the existing frameworks can
demonstrate where the interest in the technology exists and where it can be
miss-ing. This study encountered several blockchain frameworks in development.
However, there are few references to operational needs, testing, and deploy of
the technology. With the widespread use of the technology, either integrating
with pre-existing solutions, replacing legacy systems, or new implementations,
the need for testing, deploying, exploration, and maintenance is expected to
in-tensify.
