Digital libraries are critical in preserving and providing access to vast cultural and academic information. However, traditional preservation methods face challenges to data integrity, authenticity, and storage access. This research explores blockchain technology and the Interplanetary File System's potential to address security and privacy issues of digital library preservation. By leveraging blockchain's decentralized, immutable nature and smart contracts, digital libraries can achieve improved security, transparency, and accountability in their preservation. Furthermore, it presents a platform built on an elliptic curve digital signature algorithm (ECDSA) and zero-knowledge proofs cryptographic to boost the security system communication. Lastly, this framework will support a scalable double-blockchain by using flexible consensus algorithms to prevent attacks.
