FHIRChain: Applying Blockchain to Securely and Scalably Share Clinical Data

Secure and scalable data sharing is essential for collaborative clinical decision making in telemedicine. Conventional clinical data efforts are often siloed, however, which creates barriers to efficient information exchange and impedes effective treatment decision making for remote patients. This paper provides four contributions to the study of applying blockchain technology to clinical data ...

Blockchain manoeuvres: applying Bitcoin's technology to banking

Already there are ideas for using the blockchain to make payments faster and cheaper, to make it easier for small businesses to obtain finance and for banks to assess mortgage portfolios at the click of a mouse. Smart trade finance contracts are being worked on that are so watertight, they will never be argued over in court. Securities transactions could be settled in minutes rather than days. ...

IOM suggests ways to share clinical trial data.

CODS: Evolving Data Efficiently and Scalably in Column Oriented Databases

Database evolution is the process of updating the schema of a database or data warehouse (schema evolution) and evolving the data to the updated schema (data evolution). Database evolution is often necessitated in relational databases due to the changes of data or workload, the suboptimal initial schema design, or the availability of new knowledge of the database. It involves two steps: updatin...

2-hop Blockchain: Combining Proof-of-Work and Proof-of-Stake Securely∗

Cryptocurrencies like Bitcoin have proven to be a phenomenal success. Bitcoin-like systems use proofof-work mechanism which is therefore considered as 1-hop blockchain, and their security holds if the majority of the computing power is under the control of honest players. However, this assumption has been seriously challenged recently and Bitcoin-like systems will fail when this assumption is b...
