Abstract:
Blockchain technology is introduced in 2008 by Satoshi Nakamoto's paper, in which it is used as a distributed ledger to store Bitcoin cryptocurrency transactions. This technology allows for immutable data to be saved, such that once entered, it cannot be modified. This feature of the Blockchain fits perfectly with the need for companies to save and maintain the Authentication Logs of system administrators, a requirement imposed by law since 2019. The purpose of this thesis is to present the design of a product capable of saving logs within a blockchain-based system and to propose an implementation developed using the Hyperledger Fabric framework, a Linux Foundation product designed for enterprise blockchain solutions.
