Blockchain and Distributed Ledger Technology are evolving in today's digital world for faster processing and secure transactions. Most IT industries are migrating their applications to blockchain frameworks because of high security and faster processing operations. Cryptocurrencies and bitcoin applications use Blockchain and distributed ledger technology to perform decentralized transactions. With the current blockchain technology, there is a limitation in storing and processing a large volume of transactions and data, affecting memory and throughput. To overcome this limitation, we propose a methodology to integrate Blockchain with IPFS to enhance the throughput and optimize the memory. As a case study marks card validation application is being developed on the Ethereum framework considering Geth and Parity clients. Blockchain consensus protocol, i.e., proof of work (POW) and proof of stake (POS), are used to build smart contracts and process transactions. InterPlanetary File System (IPFS) is integrated with Blockchain to enhance the throughput and performance of the application. The results indicate that Blockchain integrated with IPFS performs better by optimizing the memory and reducing the transaction delay. The comparative analysis shows that the proposed approach reduces the transaction processing cost by 10% and enhances the throughput by 8% compared to the Fileshare and BlockIPFS techniques.
