Decentralised Blockchain Storage Solution: Scalable and Secure Optimisation Scheme for Efficient Data Management
Jun Wook Heo · Queensland University of Technology · 2024
As blockchain is an immutable, distributed, and decentralized ledger, blockchain full nodes face challenges related to the tremendous data size and the lack of verification of their local ledgers. This research introduces novel Proof-of-Storage solutions for blockchain full nodes, along with storage optimisation strategies aimed at reducing replicas and the overall ledger size. The Proof-of-Storage solutions can enhance the security and decentralisation of blockchain full nodes, minimising performance degradation through the use of an asymmetric encoding and decoding scheme. Meanwhile, the storage optimisation solutions can significantly reduce the number of replicas and provide a secure method for updating the ledger.
