Abstract
Distributed ledgered data is stored within a distributed persistent storage system comprising multiple persistent storage systems as distributed ledgered participants. In various embodiments, the distributed ledgered data is maintained using the native capabilities of a persistent storage system. The distributed ledgered data is replicated as persistent data objects in a 'ledgered repository of objects' that are replicated at each of the persistent storage systems. Changes at one persistent storage system are recorded within a block in a distributed blockchain that is distributed across each of the other distributed ledgered participants. The other distributed ledgered participants read the changes from the blockchain and apply the changes to the respective replicas at each of the other distributed ledgered participants. Hence, this approach is referred to as blockchain apply. Blockchain apply may be used to replicate the repository objects of various forms of PSSs. In a DBMS, a repository of objects is a table, where each record or row is an object in the repository. In a file system, a repository of objects is a directory, where each directory and file therein is an object in the repository. In a document storage system (DOCS), a repository of objects is a collection of documents, where each document is an object in the repository.
