Blind writes can cause anomalies if multiple different blind write transactions are executed at the same time.<ref>{{Cite journal |last1=Herman |first1=Nanna Suryana |last2=Anshar |first2=Khairul |last3=Andono |first3=Pulung Nurtantio |date=2022-04-01 |title=Blind Write Protocol Throughput |journal=Journal of Physics: Conference Series |volume=2224 |issue=1 |article-number=012074 |doi=10.1088/1742-6596/2224/1/012074 |issn=1742-6588|doi-access=free |bibcode=2022JPhCS2224a2074H }}</ref>
