Dirty data is the worst. Protocol manipulation and selectively published outcomes pose a real threat to clinical trial validity and patient safety. But imagine a world where this is entirely preventable. With Bitcoin, the premise could become a reality. Bitcoin- an open-source, digital currency- can now be used in the clinical trial space to prevent questionable alterations to original trial protocol and pre-specified trial measures. Using an inexpensive publically distributed, time-stamped Bitcoin technology known as a “Blockchain”, alterations to study endpoints and data can verified by any interested third party. Furthermore, changing the original source is extremely difficult. So any individual thinking about adding their own creative spin on trial outcome is looking at an almost impossible uphill battle.
