[39] In a so-called "51% attack" a central entity gains control of more than half of a network and can then manipulate that specific blockchain record at will, allowing double-spending. [40] Blockchain security methods include the use of public-key cryptography.

[5] To overcome these shortcomings, taking a traditional database and adding blockchain features to it sounds more feasible. [6]
