“It makes it really obvious when someone’s changing something,” lead author Daniel Wong said in a statement. “You can see who put their hands on it, who made it, who changed it, and who received it.”
Co-author of the paper, Atul Butte, believes that this development could have real uses in ensuring scientific integrity. “Everyone is talking about how blockchain is going to revolutionize many of the data challenges in medicine, and here is one use that finally might make sense,” he said in the same statement. “We think it could someday be useful for pharma companies running clinical trials.”
The paper is published in the journal Nature Communications.
