Abstract
A method for byzantine fault tolerant data replication with a plurality of 2f+1 data servers and one or more clients includes storing data in at least f+1 different data servers out of the 2f+1 data servers, and storing metadata of the stored data under a metadata-identifier in a metadata-service (MDS). The stored metadata includes a unique identifier of the stored data, a fingerprint of the stored data, and a list of the at least f+1 different data servers which have stored the data.
