SCALABLE DECENTRALIZED SYSTEMS BASED ON DISTRIBUTED DATA STORAGE

DOI: 10.31673/2786-8362.2025.029186

Abstract

The article presents an analysis of approaches
to improving the scalability of decentralized systems through the integration of blockchain platforms with
distributed NoSQL storage. The feasibility of using NoSQL databases as a distributed block storage layer
within the ElasticBloC model is substantiated, which allows reducing the load on the blockchain and
ensuring horizontal scalability. A system integration approach based on a multilayer software architecture
using Java and Python is considered. As a result, a conceptual model of the synergistic combination of
blockchain, NoSQL infrastructure, and application services is formulated, creating the prerequisites for
building scalable and secure decentralized applications in DeFi environments. Approaches to integrating
blockchain technologies with distributed NoSQL storage and architectural alignment of Java- and Pythonbased components within decentralized applications are systematized. The proposed solutions can be
applied in the design of information systems with high requirements for resilience, reliability, and
performance.
Keywords: blockchain, decentralized systems, distributed data storage, Java, microservices, NoSQL,
object-oriented programming, Python
