Development of an Hybrid Blockchain and NoSQL Platform to Improve Data Management

Abstract: Blockchain technology is a Distributed Ledger Technology mainly used to store information in an immutable and secure way, but scalability and throughput issues are major challenges. Integration of the NoSQL paradigm within a Blockchain pipeline enhances throughput and scalability, and it can handle both on-chain and off-chain data. This work aims to study which approaches are currently used to integrate a NoSQL database in a Blockchain architecture, how the advantages of both technologies can be exploited to enhance the system's capabilities, and to propose a novel hybrid architecture that mixes Blockchain and NoSQL characteristics.
