Abstract
Methods and systems for storing a file on a plurality of servers are provided. The number of servers is n and the maximum number of servers which may fail is t. A predefined number b of byzantine failures and a number t−b of crashes of the servers is contemplated, where n equals 2t+b+1. The file is divided into a plurality of chunks, where the number of chunks is equal to or greater than the number of servers. The chunks of the file are sent to the n servers, where at least one chunk is sent to each server. The number of replies r from the n servers indicating successful storage of the respective chunks are determined. The number of replies r matching a terminating condition is checked. A new file based is generated. The process is repeated for the new file.
