Selected versions of the database are hashed upon the blockchain. These versions can be proven to have been created at the specified time and can be proven to have been unaltered.
The state of a database at any point in time can be retrieved.
The complete history of any item can be retrieved, showing its initial contents, and the changes made to the document at each point in time.
Developing Blockchain applications is time-consuming and error-prone because familiar and well-established database development idioms are not available.
ProvenDB layers on top of a standard database engine adding core Blockchain characteristics to the database. The resulting database respects all usual database “CRUD” operations (Create-Read-Update-Delete) but also provides Immutability, Tamper Dection, Point-in-time History, and Data Provenance.Free Sign up Request A Demo
