Abstract: Blockchain has evolved into a secure and trustworthy environment for decentralized applications, offering the advantages of tamper‐resistant, while simultaneously introducing on‐chain overhead issues. The development of metaverse related smart contracts on blockchain has given rise to a compelling research inquiry concerning the secure reduction of on‐chain storage overhead. In this research, the Metaverse Off‐chain Storage Framework based on Chameleon hash (MSC), a unique framework for decentralized system based on chameleon hash, supports code or stored data updates without changing on‐chain data is presented. The index of decentralized applications' data is calculated using the Chameleon hash to ensure that the index remains unchanged during the data modification process. Simultaneously, data can be stored outside of the blockchain with proper authentication mechanisms in place. The experimental results have shown that MSC exhibits reduced on‐chain storage requirements when compared to similar frameworks. Furthermore, MSC significantly reduced overhead as compared to the direct storage of data within a smart contract.
