  Blockchain is one of the most discussed and highly accepted technologies,
primarily due to its application in almost every field where third parties are
needed for trust. Blockchain technology relies on distributed consensus for
trust, which is accomplished using hash functions and public-key cryptography.
Most of the cryptographic algorithms in use today are vulnerable to quantum
attacks. In this work, a systematic literature review is done so that it can be
repeated, starting with identifying the research questions. Focusing on these
research questions, literature is analysed to find the answers to these
questions. The survey is completed by answering the research questions and
identification of the research gaps. It is found in the literature that 30% of
the research solutions are applicable for the data layer, 24% for the
application and presentation layer, 23% for the network layer, 16% for the
consensus layer and only 1% for hardware and infrastructure layer. We also
found that 6% of the solutions are not blockchain-based but present different
distributed ledger technology.
