Abstract
A reliable log system is a prerequisite for security applications. One of the first actions a hacker takes upon penetrating a system is altering the log files. Maintaining redundant copies in a distributed manner in a Byzantine setting has always been a challenging task, however it has recently become simpler given recent advances in blockchain technologies. In this work, we present a tamperresistant log system through the use of a blockchain. We leverage the immutable write action and distributed storage provided by the blockchain and add an additional encryption layer to develop a secure log system. We assess the security and privacy aspects of our solution. Finally, we implement our system over Hyperledger Fabric and demonstrate the system's value for several use cases.
