Abstract: The present invention relates to a method and system for storing log data entries to provide a for a nonrepudiation log file that may be authenticated on an entry by entry basis. The system and method may be, or use, an encoder plug-in to translate entries into paired data and to write the translated entry to the log file in any order thereby allowing for the use of multiple processor systems. The log entries may be extracted and verified as authentic using this encoding plug-in and one or more processor systems. Various techniques may be used to prevent tampering with the log to remove a tuple and to detect unauthorized removal of data from the log. The present invention also relates to a method and system of securing and processing digital asset transactions.
