This complication relates to the disclosure of proprietary trading information that could be used to {\textquotedblleft}front-run{\textquotedblright} certain investors. The authors outline a solution to this problem, which involves the use of a cryptographic hash to indicate prioritization of transactions. This solution could facilitate widespread usage of blockchain technology in a variety of financial contexts.TOPICS: Quantitative methods, exchanges/markets/clearinghouses}, issn = {2329-0196}, URL = {https://pa.pm-research.com/content/6/2/1.12}, eprint = {https://pa.pm-research.com/content/6/2/1.12.full.pdf}, journal = {Practical Applications} }
