Abstract
There is a rising need for secure and effective ways to store and retrieve data as data privacy takes on more significance. Due to its decentralized and unchangeable nature, blockchain technology has shown potential in this sector. However, the efficiency and scalability of conventional Blockchain systems are constrained. It is suggested an Inter Planetary File System (IPFS) storage and retrieval system on the Blockchain using Elliptic Curve Cryptography (ECC) with Advanced Encryption Standard (AES) for file encryption, Access Control Lists (ACLs) for data access management, a Name Server for decentralized naming, Layered Radix Tree with Adaptive Hashing (LRT-AH) for indexing and Proof of Fair Chance (PoFC) consensus mechanism to overcome these restrictions. Before storing the data on the IPFS network, the system encrypts it using ECC-AES and uses ACLs to restrict access to only approved users. The Name Server offers a practical method of accessing the saved information without jeopardizing user privacy.. PoFC is a fair and effective consensus process since the PoFC algorithm, a revolutionary approach, guarantees that each user has an equal probability of being chosen as the next block minor. LRT-AH provides a scalable and adaptive indexing structure, optimizing data storage and retrieval operations in blockchain environments. The proposed system has demonstrated 50% improvement in efficiency for both insertion and retrieval times over traditional blockchain systems and those utilizing only IPFS. The system performance is analyzed along with scalability and efficiency, proving that it is appropriate for applications requiring massive amounts of data storage and retrieval.
