How is Blockchain used on Countermark?

Countermark uses Ethereum Blockchain to provide a secure, unalterable audit of Countermark changes.

No Countermark details are stored in the Blockchain, just a ‘hash’ (essentially a sum of all the data in the Countermark record). This hash value can be recalculated for the Countermark data, and compared with the unalterable Blockchain version to look for any alterations to confirm that the Countermark data is not compromised.

Blockchain in Countermark is available as an option, depending on your requirement.
