Abstract
A database management system stores an entry in a journal. Upon storage of the entry, the journal comprises a plurality of threaded leaf nodes and a hierarchy of interior nodes comprising hash values computed from the threaded leaf nodes. A first set of hash values is provided to prove that the entry is stored in a first version of the journal. A second set is provided to prove that the entries stored in the first version of the journal are unmodified and stored in a second version of the journal.
