You can check if/when a document was notarized (digitally certified), i.e. the digital fingerprint (hash value) of a file was stored in the blockchain. To do this, select the appropriate file (the hash value is calculated automatically), or enter the hash value manually (using copy/paste).
The used blockchain system is a test instance of "DatNoS", running on Multichain.
