METHOD AND SYSTEM FOR BYZANTINE FAULT TOLERANT DATA REPLICATION

摘要

The present invention relates to a method for byzantine fault tolerant data replication with a plurality of 2f+1 data servers and one or more clients, wherein data is stored in at least f+1 different data servers out of the 2f+1 data servers and wherein metadata of the stored data is stored under a metadata-identifier in a fault-tolerant metadata-service, wherein the metadata to be stored includes a unique identifier of the stored data, a fingerprint of the stored data and a list of data servers which have stored the data. The present invention further relates to a system for byzantine fault tolerant data replication.
