SUMMARY CHAINS IN DISTRIBUTED SYSTEMS

Abstract:

Certain aspects of the present disclosure provide techniques for summarizing data in a distributed system. Embodiments include generating an ordered list of blocks by iterating through a first group of blocks of a hash chain starting at a last block of the hash chain and adding each of the first group of blocks of the hash chain to the ordered list. Embodiments further include generating summary data by applying a summary function to the first group of blocks based on the ordered list. The summary function may take the ordered list as an input and provide the summary data of the first group of blocks as an output. Embodiments further include generating a summary block comprising the summary data and adding the summary block to a summary chain.
