Sustainable NFT Blockchain Storage for High Availability and Security

Abstract

Blockchain is the technology to secure transaction by connected ledgers. Non Fungible Token (NFT) transactions are getting popular daily from 2021 and it generates new economy world. The transactions of NFTs are stored in the blockchain but the contents of NFTs are not stored if the contents are so big amount of volume, because of higher transaction gas fee. We propose long term storage node system architecture named Sustainable Generation Manager (SGM) which is using hash based file system on storage node on blockchain to maintain these contents of data of NFTs. This paper shows the architecture, parameters and implementation of SGM on our original voting blockchain.
