LOG-STRUCTURED MERGE-TREE WITH BLOCKCHAIN PROPERTIES

Abstract:

An example operation may include one or more of storing data within a temporary memory structure, transferring the stored data from the temporary memory structure into a set of files of a log-structured merge-tree, generating a respective sequence of hashes within each file of the set of files, where the respective sequence of hashes provides proof of a sequential order in which data values are stored within the respective file, and storing the sequences of hashes in storage.
