Blockchain is becoming increasingly prominent in clinical trials due to the security and accessibility of data collected within a research program. Securing the collection and distribution of sensitive information from cyber-attacks bolsters trust in research organizers and attracts more participants in the future. Decentralized identifiers that provide verifiable, decentralized digital identities imply that patients own their data and effectively control how it is used. Blockchain aggregating a variety of data also increases program efficiency and contributes to reducing costs.
