Hyperledger is one of the most promising blockchains that provide easy-to-use smart contract functionalities. With the help of IBM and Sovrin foundation, more and more developers and consumers start to adopt HyperLedger to serve their business purposes. In 2018, a team from a Chinese company Humsen Inc. published a paper at the international conference IEEE ICSESS 2018. The research paper was on how to develop a log storage system Medusa using Hyperledger technologies.
Web logs and audit logs are two most common log types in real world enterprises and institutes. The safety and accuracy of log data is of crucial importance to data users. Unlike legacy data management systems, Hyperledger based log system provides tamper-proof and decentralized log keeping system that are immune to a high proportion of Byzantine nodes in the distributed system. Medusa provides data query and appending functionalities. Compared with log storage system proposals based on other systems such as ETH , Hyperledger-based log storage system has a huge advantage in regard of throughput and latency. This is what has made blockchain powered log system one step closer to commercialization.
