There are numerous challenges associated with\nblockchain technology, which can be categorized into technological, organizational, and environmental challenges. When examining these challenges, specifically the technological challenges emerge frequently, and solving them is considered essential for the development of blockchain technology. The challenges\nexamined in this thesis appear frequently in the literature, and different potential\nsolutions have been developed for them.
