An IT startup has developed a novel blockchain-based approach for secure linking of databases, called ChainifyDB. "Our software resembles keyhole surgery. With a barely noticeable procedure we enhance existing database infrastructures with blockchain-based security features. Our software is seamlessly compatible with the most common database management systems, which drastically reduces the barrier to entry for secure digital transactions," explains Jens Dittrich, Professor of Computer Science at Saarland University at Saarbrücken, Germany.

"If a doctor changes something in his table, it affects all other tables in the network. Subsequent changes to older table states are only possible if all doctors in the network agree," explains Jens Dittrich.

If the result is identical in all tables in the network, the changes can be accepted.

"This makes the system tamper-proof and guarantees that all network participants' tables always have the same status. Furthermore, only the shared data in the connected tables is visible to other network participants; all other contents of the home database remain private", emphasizes Dr. Felix Martin Schuhknecht, Principal Investigator of the project.

If a former participant is to be reinstated, the remaining network participants only have to agree on a "Correct" table state.
