File Validator

FV is a service for checking the integrity of files received from unreliable sources.

The file (program or document) is signed by the developer or publisher, and the digital signatures of the file are published on the blockchain.

Any user can check a file obtained from torrents or similar sources for integrity and immutability. Verification is possible even if the developer has stopped supporting or has gone out of business altogether. This is very important for outdated device drivers, which can only be found in the archives of questionable sites.

Also, FV records in the Emer blockchain have reliable time stamps, and you can find out who and when published a particular signature, as well as when the signers' records were created.
