Optimized Local Secret Sharing Techniques for Distributed Blockchain Networks

Abstract

In blockchain systems, transaction details are stored across a distributed ledger, and each peer bears the responsibility of upkeeping an identical replica of this ledger. This project explains the challenges faced by the high storage costs occurred in the traditional blockchain systems, where each peer maintains an identical copy of transaction data. A DSB system tries to tackle the high storage cost issue by incorporating cryptographic techniques. The Distributed Storage Blockchain (DSB) systems, however face communication costs during peer failures, which are often caused by denial-of-service attacks. To overcome these challenges, the DSB approach has been using a LSS approach. This method utilizes a hierarchical privacy scheme comprising a primary global secret node and multiple subordinate local secret nodes. The suggested Distributed Storage Blockchain (DSB) approach, incorporating Local Secret Sharing (LSS), enhances both storage efficiency and reduces recovery communication costs. This approach aims enhancing both the effectiveness of storage and reducing communication costs. During recovery processes. In the case of peer failures and security threats the DSB with LSS approach provides a solution for creating more resilient and resource-efficient blockchain systems.
