How is a Verisart certificate permanent?

The foundation of a Verisart certificate is the Bitcoin blockchain and the timestamp

referenced in a Verisart certificate is generated by the blockchain as the registration of

the proof of work.

 

Verisart certificates are made permanent by the distributed nature

of the blockchain whose ongoing proof of work components and timestamps make

existing records in the database stronger and more resistant to tampering whereas

other trust-based databases get weaker and more vulnerable over time.
