Blockchain systems use a distributed ledger to record transactions, with the goal of having every node in the network have an identical copy. High storage costs are associated with blockchain systems since they are similar to repetition codes. It has been argued that distributed storage blockchain (DSB) systems that include secret sharing, private key encryption, and information dispersion techniques may increase storage efficiency. When peers fail because of DoS assaults, however, the DSB incurs high communication costs. Using a local secret sharing (LSS) system with a hierarchy secret structure consisting with one global secret and numerous local secrets, we suggest a novel DSB method. The recovery and storage communication costs are reduced using the suggested DSB method with LSS.
